Choose Slack if you need a primary messaging hub with deep workflow automation, extensive app integrations, or want to manage asynchronous communication with a low cost-per-user for large teams. For optimal collaboration, many organizations use both: Slack for daily messaging and Webex for scheduled meetings.","keyDifferences":[{"label":"Primary Function","winner":"tie","entityAValue":"Video conferencing & meetings","entityBValue":"Team messaging & collaboration"},{"label":"Max Meeting Participants (Free Plan)","winner":"a","entityAValue":"100 participants, 40 min limit","entityBValue":"Not applicable (messaging platform)"},{"label":"Max Meeting Participants (Paid Plan)","winner":"a","entityAValue":"40,000 participants","entityBValue":"Not applicable (messaging platform)"},{"label":"Message History (Free Plan)","winner":"a","entityAValue":"Unlimited","entityBValue":"90 days / 10,000 messages"},{"label":"Starting Price (Monthly, Annual)","winner":"b","entityAValue":"$15.99/user/month","entityBValue":"$8.75/user/month"}],"winner":{"slug":"slack","name":"Slack"},"confidence":"high","entities":[{"name":"Cisco Webex","slug":"cisco-webex","url":"https://www.aversusb.net/entity/cisco-webex","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/cisco-webex"},{"name":"Slack","slug":"slack","url":"https://www.aversusb.net/entity/slack","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/slack"}],"faqs":[{"question":"Can Webex and Slack replace each other?","answer":"Not entirely. Webex excels at scheduled video meetings and large-scale presentations, while Slack dominates daily team messaging and workflow automation. Most organizations use both together: Slack for ongoing communication and Webex for formal meetings. Slack has added video calling (up to 50 participants on paid plans), but it's not optimized for presentations. Webex has added messaging, but it lacks Slack's integration depth."},{"question":"Which platform is more secure for sensitive data?","answer":"Webex edges ahead for enterprise security. It holds FedRAMP authorization, HIPAA compliance, and encrypts all meetings by default on all plans. Slack supports end-to-end encryption only in direct messages and on Enterprise+ plans. For regulated industries (healthcare, government, finance), Webex is the safer choice. Slack is secure for most organizations but requires Enterprise+ for meeting encryption."},{"question":"Which is cheaper for a 50-person team?","answer":"Slack is more affordable. At 50 users, Slack Pro ($8.75/month) costs $5,250 annually, while Webex Pro ($15.99/month) costs $9,594 annually—a 45% difference. However, Webex's free plan supports 40-minute meetings for 100 people, while Slack's free plan limits video to 3 people, making Webex better value if you only need basic conferencing without paid accounts."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/webex-vs-slack","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/webex-vs-slack), Webex is a video conferencing platform optimized for meetings with up to 40,000 participants and advanced security features, while Slack is a team messaging platform designed for asynchronous communic","dateModified":"2026-06-14T17:33:56.901Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/webex-vs-slack","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/webex-vs-slack","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/webex-vs-slack","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/webex-vs-slack#claimreview","url":"https://www.aversusb.net/compare/webex-vs-slack","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"Webex vs Slack","reviewBody":"Webex is a video conferencing platform optimized for meetings with up to 40,000 participants and advanced security features, while Slack is a team messaging platform designed for asynchronous communication and workflow integration.
