The most common encryption models for business messaging apps are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\"><strong>TLS<\/strong> (Transport Layer Security). All messages are encrypted in transit (while the message is being sent). Apart from the intended recipient who can decrypt the message and read it, the messages may also be accessed from the server side. This is usually only done when a company needs to give access to messages for legal reasons (e.g., a harassment case). TLS level security also allows apps to offer \u201cglobal search\u201d, allowing employees to search for files shared before they were added to the app\u2019s workspace, and similar.<\/li>\n\n\n\n<li class=\"translation-block\"><strong>End-to-End encryption<\/strong> (E2EE). All messages are encrypted by the sender and can exclusively be decrypted by the receiver. There\u2019s no server side access. E2EE is insisted upon by companies dealing with highly sensitive data (such as governments, hospitals, etc.). The downside is that it often imposes the limitation on searching through messages for important documents or accessing chats on the server side for legal reasons, so many businesses often avoid it \u2014 for better day-to-day functionality of the app.<\/li>\n<\/ul>\n\n\n\n<h3 id=\"security-compliance-certifications\" class=\"wp-block-heading translation-block\">Security compliance certifications<\/h3>\n\n\n\n<p class=\"translation-block\">Security compliance certifications represent official awards granted by accredited, independent third parties. They verify a given company&#8217;s security program and guarantee that it meets a specific, recognized standard.<\/p>\n\n\n\n<p class=\"translation-block\">The most common security certifications for business messaging apps include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\"><a href=\"https:\/\/online.utulsa.edu\/blog\/what-is-soc-2-compliance\/\" target=\"_blank\"

were very easy to grasp. I also like the personalization features, like the option to arrange my workspace just the way I prefer.<\/p>\n\n\n\n<p class=\"translation-block\">In Pumble, users can, among other things:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Set up group individual chats and <a href=\"https:\/\/pumble.com\/features\/channels\" target=\"_blank\" rel=\"noreferrer noopener\">channels<\/a>,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Make voice and video calls,<\/li>\n\n\n\n<li class=\"translation-block\">Send <a href=\"https:\/\/pumble.com\/features\/voice-messages\" target=\"_blank\" rel=\"noreferrer noopener\">voice<\/a> and <a href=\"https:\/\/pumble.com\/features\/video-messages\" target=\"_blank\" rel=\"noreferrer noopener\">video messages<\/a>,<\/li>\n\n\n\n<li class=\"translation-block\">Set different color themes, and&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Turn notifications on or off on a per-channel basis or for the whole app.<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block\">I think it\u2019s equally suited to remote, hybrid, and in-person environments, since it has <strong>virtually no learning curve<\/strong>.

Despite this, it still looked secure, and its security features backed this up.<\/p>\n\n\n\n<p class=\"translation-block\">Regardless of the subscription tier, Slack implements encryption (TLS) for all customer data \u2014 both the data traveling publicly and the data at rest.<\/p>\n\n\n\n<p class=\"translation-block\">However, Slack\u2019s more <strong>advanced administrative controls<\/strong> such as workspace-wide policies, granular permissions, Data Loss Prevention (DLP), and eDiscovery tools, are o<strong>nly available on more expensive plans<\/strong> (the Pro and Enterprise+ plans, depending on the feature).<\/p>\n\n\n\n<p class=\"translation-block\">Slack offers a vast list of security certifications allowing specific industries to be compliant with their requirements. The most important ones are:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">SOC 2 Type II and SOC 3,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">ISO\/IEC 27001, 27017, 27018,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">FedRAMP moderate authorization (for US government agencies),&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">GDPR,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">HIPAA, and&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">FINRA compliance support.&nbsp;&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block\">However, <a href=\"https:\/\/pumble.com\/slack-pricing\" target=\"_blank\" rel=\"noreferrer noopener\">Slack\u2019s pricing<\/a> doesn\u2019t offer much choice in terms of payment for a heavily regulated business \u2014 the Enterprise+ plan is the only option that can provide <strong>all<\/strong> of the necessary tools to meet high-risk and compliance obligations, with a <strong>custom and relatively expensive price<\/strong>.<\/p>\n\n\n\n<p class=\"translation-block\">Many of the advanced security features are only available to Enterprise+ users \u2014 the most expensive plan available for the platform with a \u201ccustom\u201d price.

Its appeal grew steadily over the years due to its <strong>open-source nature and commitment to privacy<\/strong>. Significant mainstream recognition came in late 2020 and early 2021, after <a href=\"https:\/\/www.inc.com\/jason-aten\/how-signal-became-most-popular-app-in-world-overnight-why-it-matters.html\" target=\"_blank\" rel=\"noreferrer noopener\">concerns about privacy policies<\/a> of rival messaging apps were raised.<\/p>\n\n\n\n<p class=\"translation-block\">Its interface is simple enough, and does just what you would expect from a consumer-grade chat app.<\/p>\n\n\n\n<p class=\"translation-block\">To me, the app shines at its brightest when it&#8217;s used for personal day-to-day communication or secret one-on-one talks with its <strong>\u201cdisappearing messages\u201d feature<\/strong>.<\/p>\n\n\n\n<p class=\"translation-block\">The user\u2019s identity is tied to a personal phone number, and the account is secured with a user-created PIN. Within a group, its <strong>creator can add or remove members<\/strong>, but there are <strong>no granular, role-based permissions like RBAC<\/strong>.<\/p>\n\n\n\n<p class=\"translation-block\">In terms of security, which is Signal\u2019s most talked about strength, the app uses the open source Signal Protocol to provide mandatory, always-on end-to-end encryption (E2EE).&nbsp;<\/p>\n\n\n\n<p class=\"translation-block\">This means that <strong>only the sender and intended recipient can ever access the content of<\/strong> all messages, voice calls, and video calls.<\/p>\n\n\n\n<p class=\"translation-block\">However, the central paradox of Signal is that its greatest strengths from a privacy perspective are its most critical weaknesses from the perspective of corporate risk management.<\/p>\n\n\n\n<p class=\"translation-block\">Signal offers <strong>virtually no administrative controls in a business context<\/strong>. While a user can create and manage a group, there are no central dashboards, data retention policies, or user management features.<\/p>\n\n\n\n<p class=\"translation-block\">The platform is designed well for peer-to-peer communication, but, unfortunately, it just isn\u2019t suitable for corporate oversight.<\/p>\n\n\n\n<p class=\"translation-block\">Enterprise-grade controls for policy enforcement and platform oversight are completely absent. The authentication and authorization features are intentionally minimal for user privacy.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block\">There is no central identity management or support for automated user provisioning like SCIM. Finally, there is no support for enterprise features like SSO.<\/p>\n\n\n\n<p class=\"translation-block\">All in all, Signal is a product deliberately designed for individual consumer privacy. The lack of an administrative console, user management, and no compliance certifications all imply that <strong>although Signal offers great security, the tool simply isn\u2019t built for business organizations<\/strong>.<\/p>\n\n\n\n<p class=\"custom-btn translation-block\"><a href=\"https:\/\/pumble.com\/register\" target=\"_blank\" rel=\"noreferrer noopener\">Try Pumble \u2014 a communication tool built for businesses<\/a><\/p>\n\n\n\n<h3 id=\"wire-a-good-balance-between-security-and-usability\" class=\"wp-block-heading translation-block\"><a href=\"https:\/\/wire.com\/en\/\" target=\"_blank\" rel=\"noreferrer noopener\">Wire<\/a> \u2014 A good balance between security and usability<\/h3>\n\n\n\n<p class=\"translation-block\"><strong>User experience: <\/strong>Secure, clean, professional<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Security: <\/strong>Mandatory, open-source E2EE, GDPR, SOC 2 Type II, ISO\/IEC 27001, SSO, Microsoft Entra ID (Azure AD) and Okta IdP integration, RBAC<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Business oriented: <\/strong>Yes<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Most affordable paid plan: <\/strong>\u20ac7.45 (~$8.65) per user per month (billed annually)<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"434\" src=\"https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Wire-UI.jpeg\" alt=\"Wire interface\" class=\"wp-image-11484\" srcset=\"https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Wire-UI.jpeg 1200w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Wire-UI-300x109.jpeg 300w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Wire-UI-1024x370.jpeg 1024w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Wire-UI-768x278.jpeg 768w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Wire-UI-18x7.jpeg 18w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption class=\"wp-element-caption\">Wire interface<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"translation-block\">Wire is a messaging app widely recognized for achieving a <strong>strong balance between good security and a modern, user-friendly interface<\/strong>.<\/p>\n\n\n\n<p class=\"translation-block\">To me, it feels like a crossover between a business-grade and consumer-grade app, with a little more versatility in the ways you organize and navigate your conversations.<\/p>\n\n\n\n<p class=\"translation-block\">Apart from the basic chat and call functionalities, Wire allows you to:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Store favorite chats,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Archive them,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Sort them into folders, and&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Connect with other users who sign on to the app from their email address.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block\">Its guest feature allows you to<strong> temporarily include external collaborators<\/strong>, similar to Pumble.<\/p>\n\n\n\n<p class=\"translation-block\">With their Proteus protocol, Wire enforces E2EE for every single message. In addition, <strong>every message on Wire is encrypted with a new key<\/strong> for maximum security. The conversation history is stored locally on each user&#8217;s device, and can\u2019t be accessed on the server.<\/p>\n\n\n\n<p class=\"translation-block\">As far as administrative controls go, Wire also allows admins to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Manage the full user lifecycle (onboarding and offboarding),<\/li>\n\n\n\n<li class=\"translation-block\">Create and manage teams and user roles, and<\/li>\n\n\n\n<li class=\"translation-block\">Set security policies, such as the \u201cdevice screen lock\u201d requirement.<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block\">Wire supports SSO and employs a RBAC model for managing user permissions and access to conversations. It also supports SCIM for automated user provisioning and de-provisioning.<\/p>\n\n\n\n<p class=\"translation-block\">Wire\u2019s greatest downsides for the most security-heavy organizations are the <strong>lack of native 2-factor authentication <\/strong>and <strong>metadata sensitivity<\/strong> (the patterns of communication are visible to the platform operator, which may be a disqualifying factor for organizations with the most rigorous security needs).<\/p>\n\n\n\n<p class=\"translation-block\">Another important thing to watch for here is the pricing. The <strong>\u20ac7.45 (~$8.65) price per seat <\/strong>(billed annually) is suitable for <strong>teams of up to 100 people<\/strong>. After that, you\u2019ll have to contact Wire\u2019s sales team for a custom price.<\/p>\n\n\n\n<p class=\"translation-block\">Wire is a solid choice if your organization operates in a highly regulated industry, or it requires absolute confidentiality. However, if your priority is <a href=\"https:\/\/pumble.com\/blog\/how-to-boost-productivity-at-work\/\" target=\"_blank\" rel=\"noreferrer noopener\">maximizing productivity<\/a> through a seamless workflow, a more feature-rich app like Pumble is a better choice.<\/p>\n\n\n\n<p class=\"custom-btn translation-block\"><a href=\"https:\/\/pumble.com\/register\" target=\"_blank\" rel=\"noreferrer noopener\">Super-charge team productivity with Pumble<\/a><\/p>\n\n\n\n<p class=\"translation-block\">With the \u201cprivacy purist\u201d apps covered, let\u2019s take a look at the widely known, but risky crossovers \u2014 WhatsApp, Telegram, and Discord.<\/p>\n\n\n\n<h3 id=\"whatsapp-good-for-external-communication\" class=\"wp-block-heading translation-block\"><a href=\"https:\/\/www.whatsapp.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">WhatsApp<\/a> \u2014 Good for external communication<\/h3>\n\n\n\n<p class=\"translation-block\"><strong>User experience: <\/strong>Intuitive, people-oriented, consumer-grade<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Security compliance certifications:<\/strong> E2EE through Signal protocol, no security compliance certifications, authentication through a personal phone number<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Business oriented: <\/strong>No<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Most affordable paid plan: <\/strong>It\u2019s free.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"654\" src=\"https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/WhatsApp-UI.jpeg\" alt=\"WhatsApp interface\" class=\"wp-image-11483\" srcset=\"https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/WhatsApp-UI.jpeg 1200w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/WhatsApp-UI-300x164.jpeg 300w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/WhatsApp-UI-1024x558.jpeg 1024w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/WhatsApp-UI-768x419.jpeg 768w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/WhatsApp-UI-18x10.jpeg 18w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption class=\"wp-element-caption\">WhatsApp interface<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"translation-block\">Being arguably one of the most popular communication apps in the entire world, WhatsApp probably needs no introduction.<\/p>\n\n\n\n<p class=\"translation-block\">It has developed a reputation as an essential and reliable utility for personal communication.<\/p>\n\n\n\n<p class=\"translation-block\">The business version of the app, called WhatsApp Business (billed on a per-message basis), allows you to:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Create a business profile with an address and business hours,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Organize chats with labels such as \u201cpending\u201d or \u201cresolved\u201d,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Set automatic replies, and similar.<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block\">In terms of security, WhatsApp provides mandatory, strong E2EE for all messages, calls, and file transfers using the highly-regarded Signal Protocol.<\/p>\n\n\n\n<p class=\"translation-block\">As far as administrative controls go, <strong>WhatsApp offers no central dashboard<\/strong> to manage multiple employee users, enforce security policies, or oversee communications.<\/p>\n\n\n\n<p class=\"translation-block\">Upon testing it, it was obvious to me that the app was designed primarily with one-on-one personal communication in mind, and small to medium-sized group conversations.<\/p>\n\n\n\n<p class=\"translation-block\">In terms of business use, WhatsApp can be very useful as a <strong>means to reach out and run a small business as an entrepreneur<\/strong>, especially if your work requires frequent one-on-one <a href=\"https:\/\/pumble.com\/blog\/best-customer-communication-tools\/\" target=\"_blank\" rel=\"noreferrer noopener\">client communication<\/a>.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block\">However, as a consumer-first application, WhatsApp is simply not designed to meet the data governance, auditing, and control requirements of regulated industries \u2014 which also means no security compliance certifications for larger teams.<\/p>\n\n\n\n<p class=\"translation-block\">Finally, there is no central system for managing users or automatic account provisioning and de-provisioning, making it impossible for a business to control employee access securely. The same goes for important company information.<\/p>\n\n\n\n<p class=\"translation-block\">Overall, the business version of the app is a tool that\u2019s very well designed for small businesses to communicate with external customers, as it can serve as a \u201cdigital storefront\u201d. Plus, it\u2019s quite cost-effective, especially for businesses that are just starting out.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block\">On the other hand, due to the complete lack of administrative controls, compliance certifications, and identity management features, it might not be the best choice for medium or large companies.<\/p>\n\n\n\n<p class=\"custom-btn translation-block\"><a href=\"https:\/\/pumble.com\/register\" target=\"_blank\" rel=\"noreferrer noopener\">Handle complex communication challenges easily with Pumble<\/a><\/p>\n\n\n\n<h3 id=\"telegram-optional-e2ee-whatsapp-alternative-for-individual-users\" class=\"wp-block-heading translation-block\"><a href=\"https:\/\/telegram.org\/\" target=\"_blank\" rel=\"noreferrer noopener\">Telegram<\/a> \u2014 Optional E2EE WhatsApp alternative for individual users<\/h3>\n\n\n\n<p class=\"translation-block\"><strong>User experience:<\/strong> Minimalist approach, user friendly, consumer grade<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Security:<\/strong> TLS, E2EE in \u201csecret chats\u201d, no compliance certifications, authentication through a personal phone number<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Business oriented:<\/strong> No<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Most affordable paid plan: <\/strong>It\u2019s free.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"471\" src=\"https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Telegram-UI.jpeg\" alt=\"Telegram interface\" class=\"wp-image-11482\" srcset=\"https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Telegram-UI.jpeg 1200w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Telegram-UI-300x118.jpeg 300w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Telegram-UI-1024x402.jpeg 1024w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Telegram-UI-768x301.jpeg 768w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Telegram-UI-18x7.jpeg 18w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption class=\"wp-element-caption\">Telegram interface<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"translation-block\">Telegram is a messaging app that feels like a <strong>fast and feature-rich hybrid between a private messenger and a social media platform<\/strong>.<\/p>\n\n\n\n<p class=\"translation-block\">It offers all the expected features of a consumer-grade messaging app, such as messaging, calls, creating group chats, calling other users, sharing files, and chat search. To me, it feels more focused on speed, customization, and large-scale community features than WhatsApp.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block\">It even evokes a sense of being a \u2018power-user\u2019 tool, especially when we take into account Telegram\u2019s strong stance on privacy and freedom of speech.<\/p>\n\n\n\n<p class=\"translation-block\">To achieve maximum security for its users, Telegram&#8217;s chats use client-server encryption (TLS) as a default, with E2EE available as an optional feature called &#8220;Secret Chats&#8221;. They are limited to one-on-one conversations, and they do not sync across devices.<\/p>\n\n\n\n<p class=\"translation-block\">However, group chats and channels are never end-to-end encrypted.<\/p>\n\n\n\n<p class=\"translation-block\">As far as businesses are concerned, Telegram offers controls for managing communities, but isn\u2019t very suitable for managing a large corporate workforce. In groups and channels, admins can:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\">Add or remove members,&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Set granular permissions (control what content members can post),&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Manage chat history, and&nbsp;<\/li>\n\n\n\n<li class=\"translation-block\">Pin messages.<\/li>\n<\/ul>\n\n\n\n<p class=\"translation-block\">However, Telegram offers <strong>no central dashboard<\/strong> for a business to manage multiple employee accounts.&nbsp;<\/p>\n\n\n\n<p class=\"translation-block\">This means that a business cannot enforce security policies or oversee company-wide data, which is a major downside for business use. Same as with WhatsApp, SSO is not supported in Telegram.<\/p>\n\n\n\n<p class=\"translation-block\">Permissions are limited to group and channel administration (e.g., the ability to ban users) and there is <strong>no central system for a business to manage employee identities <\/strong>or automate account provisioning and de-provisioning.<\/p>\n\n\n\n<p class=\"translation-block\">Similar to WhatsApp, user identity is tied to a phone number, though Telegram also allows its users to create a public username.<\/p>\n\n\n\n<p class=\"translation-block\">Although Telegram&#8217;s powerful channel and group features are often used by businesses for community engagement, this tool is still a consumer messaging app in essence.<\/p>\n\n\n\n<p class=\"translation-block\">In my opinion, Telegram can be more than sufficient for micro-sized or small teams and companies in need of a fast messaging app with a minimalist design. Backed with strong E2EE and personal data protection, it could be a solid choice \u2014 if access to all messages after a team member leaves the company is not of utmost importance.<\/p>\n\n\n\n<p class=\"translation-block\">On the other hand, the absence of any corporate compliance certifications and the complete lack of enterprise identity management tools make it unsuitable and insecure for internal business collaboration where security and compliance are a priority \u2014 especially for medium and large teams.<\/p>\n\n\n\n<p class=\"translation-block\">\n<div class=\"banner banner-dark pumble-gradient-landing-3\">\n    <div class=\"banner-text lg:pr-[6rem]\">\n        <h2 class=\"translation-block text-2xl !mb-4\">Communication made easy<\/h2>\n        <p class=\"translation-block !text-sm\">Improve collaboration and cut down on emails by moving your team communication to Pumble.<\/p>\n\n        <div class=\"banner-buttons d-flex space-x-4 translation-block\">\n            <a class=\"rounded-md px-6 py-2 bg-white\" href=\"https:\/\/pumble.com\/register\" target=\"_blank\">Sign up<\/a>\n\n                            <a class=\"button-2\" href=\"https:\/\/pumble.com\" target=\"_blank\">Learn more<\/a>\n                    <\/div>\n    <\/div>\n\n    <div class=\"banner-image banner-image-bottom \">\n        <picture>\n            <source srcset=\"https:\/\/pumble.com\/learn\/wp-content\/themes\/cake-learn\/src\/images\/pumble\/banners\/landing-3@2x.png 2x\" alt=\"Illustration\"  media=\"(min-width: 1022px)\" \/>\n            <img decoding=\"async\" src=\"https:\/\/pumble.com\/learn\/wp-content\/themes\/cake-learn\/src\/images\/pumble\/banners\/landing-3.png\"  alt=\"Illustration\" \/>\n        <\/picture>\n    <\/div>\n<\/div>\n    <\/p>\n\n\n\n<h3 id=\"discord-solid-user-controls-good-for-personal-use\" class=\"wp-block-heading translation-block\"><a href=\"https:\/\/discord.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">Discord<\/a> \u2014 Solid user controls good for personal use<\/h3>\n\n\n\n<p class=\"translation-block\"><strong>User experience:<\/strong> Casual, customizable, not really private<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Security compliance certifications:<\/strong> TLS, no security compliance certifications, 2FA, RBAC<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Business oriented: <\/strong>No<\/p>\n\n\n\n<p class=\"translation-block\"><strong>Most affordable paid plan: <\/strong>$2.49 per user per month (billed annually)<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"685\" src=\"https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Discord-UI.jpeg\" alt=\"Discord interface\" class=\"wp-image-11477\" srcset=\"https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Discord-UI.jpeg 1200w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Discord-UI-300x171.jpeg 300w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Discord-UI-1024x585.jpeg 1024w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Discord-UI-768x438.jpeg 768w, https:\/\/pumble.com\/learn\/wp-content\/uploads\/2025\/09\/Discord-UI-18x10.jpeg 18w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption class=\"wp-element-caption\">Discord interface<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"translation-block\">Discord is a community chat platform organized into servers, best known for a unique blend of <strong>text channels and \u201cdrop-in\u201d voice channels<\/strong> that create a social hangout space.<\/p>\n\n\n\n<p class=\"translation-block\">I\u2019d describe Discord\u2019s vibe as informal and community-driven \u2014 which is either the best thing or the worst thing about it, depending on your team\u2019s size and workplace culture.<\/p>\n\n\n\n<p class=\"translation-block\">The biggest reasons for Discord&#8217;s popularity are its <strong>high-quality audio calls and seamless server and channel hopping experience<\/strong>. For some users this is a standout feature, because it allows people to always be connected while collaborating. In a business setting, users often make use of this by being muted while working and unmuting themselves when they need to ask someone a question.<\/p>\n\n\n\n<p class=\"translation-block\">Discord allows admins to <strong>create servers with a detailed hierarchy and specific permissions<\/strong>. This gives server owners the opportunity to control everything from someone\u2019s ability to speak in a channel, all the way to sending messages, or allowing other users to manage server members.<\/p>\n\n\n\n<p class=\"translation-block\">However, fundamentally, these controls are designed for online communities, not a corporate environment. Like the two previous consumer-grade apps I mentioned, Discord doesn&#8217;t have the central dashboard to manage multiple servers under one business profile.<\/p>\n\n\n\n<p class=\"translation-block\">Discord does support a strong 2FA, but it does not support enterprise SSO. Also, there is no support for automated user provisioning and de-provisioning.<\/p>\n\n\n\n<p class=\"translation-block\">Despite the powerful role and permission system, Discord is fundamentally still a consumer and community platform.<\/p>\n\n\n\n<p class=\"custom-btn translation-block\"><a href=\"https:\/\/pumble.com\/register\" target=\"_blank\" rel=\"noreferrer noopener\">Stay compliant and secure with Pumble<\/a><\/p>\n\n\n\n<p class=\"translation-block\">The absence of any business compliance certifications and the inability to integrate with enterprise identity systems make it mostly unsuitable and insecure for confidential internal business communication of medium and large teams. On the other hand, I can see how <strong>small teams with a casual work ethic could enjoy the benefits of the laid back design and feel<\/strong>.<\/p>\n\n\n\n<p class=\"translation-block\">It is also worth mentioning that Discord announced <a href=\"https:\/\/discord.com\/press-releases\/discord-launches-teen-by-default-settings-globally\" target=\"_blank\" rel=\"noreferrer noopener\">age assurance checks<\/a> starting in the second half of 2026. To access sensitive or age-restricted servers and channels, users will need to verify their age through a facial scan or by submitting an ID.&nbsp;<br>This change aims to protect teens using the app, and while it adds a layer of security for restricted content, it has raised questions among members as to how their data is handled.<\/p>\n\n\n\n<p class=\"translation-block\">_______<\/p>\n\n\n\n<p class=\"translation-block\">Concluding our list with 3 consumer-grade apps, it\u2019s important to note that using these types of tools for business purposes creates what is known in the IT world as <a href=\"https:\/\/www.ncsc.gov.uk\/guidance\/shadow-it\" target=\"_blank\" rel=\"noreferrer noopener\">Shadow IT<\/a>, specifically because of the lack of data control.<\/p>\n\n\n\n<p class=\"translation-block\">This practice is considered a significant security risk not because the apps themselves are inherently malicious, but because they fail to deliver the fundamental requirements of a corporate environment. Keep that in mind when choosing a tool based on security for your business.<\/p>\n\n\n\n<div class=\"wp-block-group pro-tip\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"translation-block\"><strong>\ud83c\udf93 Pumble Pro Tip<\/strong><\/p>\n\n\n\n<p class=\"translation-block\">Check out a direct comparison of Discord and Pumble for team communication:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"translation-block\"><a href=\"https:\/\/pumble.com\/blog\/pumble-vs-discord\/\" target=\"_blank\" rel=\"noreferrer noopener\">Pumble vs Discord: Pricing, Features, and Professional Use Compared<\/a><\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<p class=\"translation-block\">\n<div class=\"banner banner-light pumble-gradient-pricing\">\n    <div class=\"banner-text lg:pr-[6rem]\">\n        <h2 class=\"translation-block text-2xl !mb-4\">Boost team productivity<\/h2>\n        <p class=\"translation-block !text-sm\">Make communication simple and effective.
