How many users does Webex have?

Cisco’s most current disclosure puts Webex Calling at more than 18 million cloud users and Cisco’s combined cloud-plus-on-prem calling base at more than 50 million users. Suite-level meeting users are not broken out as a single figure in current Cisco IR releases, so the calling-installed-base numbers are the most recent primary-sourced count Cisco itself publishes.

Webex Calling Users and Market Reach

Webex Calling is the cloud arm of Cisco’s broader calling installed base. Per Cisco’s WebexOne blog disclosures, the cloud-share ratio sits at more than 18 million of more than 50 million combined Cisco calling users (more than a third) today, with the remaining roughly two-thirds still anchored on UCM on-premises. That ratio is the practical context for any “Webex Calling growth” narrative; the cloud transition is real, but on-premises UCM is still the larger half of the calling base.

• Webex Calling reaches more than 18 million users across 195+ markets worldwide.
• Cisco UCM on-premises serves over 30 million users worldwide, the larger half of the combined calling base.
• One of the world’s largest retailers runs Webex Calling for more than 1.4 million users across 4,600+ locations at 99.999% availability.
• Cisco’s own internal migration to Webex Calling covers over 84,000 employees, the platform’s largest reference deployment.
• Webex Calling availability covers over 95% of global GDP across its 195+ market footprint.

By the numbers: Webex Calling reaches more than 18 million users across 195+ markets representing 95% of global GDP, with one named retailer running more than 1.4 million users across 4,600+ locations at 99.999% availability. Per Cisco’s WebexOne 2025 disclosures, that places Webex Calling at roughly a third of Cisco’s broader 50 million-user calling installed base.

For Microsoft 365 statistics, Microsoft’s seat base offers a useful frame for how Webex Calling’s 18 million cloud number compares against suite-bundled competitors.

Webex Contact Center Scale and Enterprise Deployments

Webex Contact Center is Cisco’s enterprise-grade CCaaS arm, packaging voice, digital, and AI Agent capabilities. According to the Cisco Newsroom briefing, deployments reach up to 36,000 concurrent agents, with double-digit Contact Center product-order growth in Q1 FY26 alongside a 200+ new-feature batch and an expanded 160-country footprint.

• Webex Contact Center product orders posted double-digit growth year over year in Q1 FY 2026, one of Collaboration’s stronger sub-segments.
• Cisco delivered over 200+ new Webex Contact Center features in a single quarter (Q1 FY26).
• Webex Contact Center increased its global footprint to 160 countries and scaled to support deployments of 50,000+ voice agents.
• Webex Contact Center Enterprise supports up to 36,000 concurrent agents in a single deployment.
• Maersk adopted the entire Webex Suite and deployed a 15,000-seat contact center spread across 150 locations.

Cisco Collaboration Segment Revenue (FY25 Full Year)

Cisco’s Collaboration segment is the home of Webex inside the company’s IR breakdown. Full-year FY25 Collaboration revenue closed at $4,154 million, up 1% year over year on a flat base, with Devices, Webex Suite, and CPaaS as the named drivers; the Q4 FY25 quarter contributed $1,042 million of the annual total at +2% YoY.

• Cisco FY25 Collaboration revenue totaled $4,154 million, up 1% year over year.
• The segment’s growth was driven by Devices, Webex Suite, and CPaaS offerings, per Cisco’s full-year IR commentary.
• Q4 FY25 Collaboration revenue stood at $1,042 million, up 2% year over year.
• Cisco total revenue for FY25 reached $56.7 billion, an increase of 5%.
• Q4 FY25 Cisco revenue was $14.7 billion, up 8% year over year.

Collaboration Segment Quarter-by-Quarter (Q3 FY25 to Q1 FY26)

The three-quarter window tells a more pointed story than the full-year roll-up. Q3 FY25 Collaboration revenue grew 4% year over year; Q4 FY25 slowed to 2%; Q1 FY26 turned negative at –3%. The mix shift lines up with FY25 commentary naming Devices and Webex Suite as drivers, then naming both as the drag one quarter later.

• Q3 FY25 Collaboration revenue was $1,031 million, up 4% year over year.
• Q4 FY25 Collaboration revenue was $1,042 million, up 2% year over year.
• Q1 FY26 Collaboration revenue came in at $1.1 billion, down 3% year over year.
• Cisco said the Q1 FY26 Collaboration result reflected declines in Devices and WebEx, partially offset by growth in CPaaS.
• Cisco Q1 FY26 total product revenue was up 10%, driven by AI Infrastructure and campus networking solutions, with AI infrastructure orders of $1.3 billion in the quarter.

Source: Cisco Investor Relations and Newsroom (Q3 FY25, Q4 FY25, Q1 FY26 earnings)

The deceleration trajectory matters more than the absolute Collaboration figure; Cisco’s Q1 FY26 prepared remarks name Devices and Webex as the drag, with CPaaS softening the decline rather than reversing it.

Webex AI Assistant and AI Agent Adoption

Webex AI Agent became generally available on March 31, 2025, and Cisco’s WebexOne 2025 customer disclosures show early adopters cut self-service operational costs by 31% and average handle time by 8%. Two named customers, CarShield and the broader Maersk Contact Center deployment, anchor the case-study layer.

• Early adopters of Webex AI Agent saw a 31% reduction in self-service operational costs.
• Contact centers using Webex AI Assistant cut average handle time by 8%.
• Webex AI Agent became generally available on March 31st, 2025, providing autonomous self-service across both digital and voice channels.
• Webex AI Assistant will soon support over 50+ languages, including transcription, summaries, and other AI-powered features.
• CarShield, deploying Webex AI Agent for claims processing, posted a 23% reduction in call-handling time and a 66% gain in processing efficiency.

For broader AI agent adoption data, the Webex AI Agent figures sit alongside the wider enterprise AI-agent rollout numbers SQ Magazine tracks across vendors.

Webex Market Share vs Zoom, Microsoft Teams, RingCentral

The SRG 2022 UCaaS market analysis remains the most-cited public market-share breakdown, even as the underlying figures have aged. RingCentral led at approximately 21% share with 24% growth; Microsoft and Zoom each held approximately 10% share with 40% YoY growth; Cisco sat in the relatively flat tier alongside 8×8 and LogMeIn. The competitive shape, Microsoft and Zoom growing fastest while Cisco defends share through enterprise depth, has carried into more recent industry commentary.

• Total UCaaS subscribers grew over 21 million, with subscriber base growth of 20% year over year.
• The US represented nearly three-quarters of UCaaS subscribers in the analyzed period.
• Microsoft and Zoom each held approximately 10% market share, with both growing 40% year over year.
• RingCentral led the market at approximately 21% share with 24% growth in Q2.
• Cisco’s market share, alongside 8×8 and LogMeIn, remained relatively flat in the analyzed window.

Why it matters: SRG’s UCaaS data places RingCentral at approximately 21% share with 24% growth, while Microsoft and Zoom each held approximately 10% with 40% YoY growth, and Cisco sat in the relatively flat tier alongside 8×8 and LogMeIn. Cisco defends share through enterprise depth (calling plus contact center bundles), not subscriber-count lead.

Is Webex bigger than Zoom or Microsoft Teams?

By UCaaS subscriber share, no, Microsoft and Zoom each held approximately 10% share, growing 40% year over year, while Cisco sat in the relatively flat tier in the SRG analysis. By calling installed base, Cisco’s more than 50 million combined calling users (cloud and on-prem) and more than 18 million Webex Calling cloud users still represent enterprise scale. Microsoft and Zoom do not match in the legacy on-prem footprint.

Webex Suite Pricing and Plan Mix

Cisco bundles Webex Calling, Meetings, Messaging, and Contact Center inside the broader Webex Suite, sold through subscription seat licenses with Suite, Enterprise, and Contact Center tiers. Public pricing pages show Webex Calling published seat tiers; enterprise pricing is contract-negotiated. Two publicly-named Webex Calling deployments include Cisco’s own 84,000-seat internal rollout and a more than 1.4 million-user retailer migration, confirming the seat-based model scales without a hard published ceiling.

• The named retailer’s Webex Calling migration includes more than 1.4 million users across 4,600+ locations with reported 99.999% availability.
• Cisco’s own internal Webex Calling deployment covers over 84,000 employees, the largest internal seat reference for Cisco itself.
• Webex Contact Center Enterprise supports up to 36,000 concurrent agents in a single deployment, the published ceiling for Contact Center seat licensing.
• Cisco’s segment commentary names Webex Suite and Devices as growth drivers within FY25 Collaboration, indicating Suite-tier sales are the prevailing motion at the high end.

How much does Webex cost for businesses?

Webex Suite pricing is contract-negotiated for enterprise tiers and seat-license-based for SMB. Cisco does not publish all-tier pricing in IR releases, but the largest disclosed reference deployments, more than 1.4 million retailer users with reported 99.999% availability and over 84,000 Cisco internal Webex Calling seats, confirm the per-seat model scales to mass-deployment volumes inside the Webex Suite, Webex Calling, and Webex Contact Center bundles.

Webex Devices Portfolio (Desk, Board, Room Kits)

Webex Devices include the Cisco Desk Series, Cisco Board Series, and Cisco Room Kits, sold both as standalone hardware and as bundled accessories inside Webex Suite contracts. Cisco’s full-year FY25 commentary named Devices as one of the three Collaboration segment growth drivers; the Q1 FY26 commentary then named Devices as part of the segment’s 3% decline, illustrating the hardware cycle’s quarter-to-quarter volatility.

• Cisco named Devices, Webex Suite, and CPaaS as the FY25 Collaboration revenue growth drivers.
• Q1 FY26 Collaboration’s 3% decline reflected drops in Devices and WebEx, partially offset by CPaaS growth.
• The Webex Devices portfolio supports the 36,000-agent Contact Center ceiling and 50,000+ voice-agent deployment scale when paired with Cisco’s Suite-tier subscriptions.

Webex Integrations Footprint (Microsoft 365, Salesforce, ServiceNow)

Webex’s integration story leans on Cisco’s Connected Intelligence framing, embedding Webex AI Assistant, Webex Calling, and Webex Contact Center inside customer workflows that already run on Microsoft 365, Salesforce, ServiceNow, and similar enterprise platforms. Cisco delivered 200+ new Webex Contact Center features in Q1 FY26 and expanded the global footprint to 160 countries.

• Webex Contact Center delivered over 200+ new features in Q1 FY 2026, a release cadence built around integration depth.
• Webex Contact Center expanded its global footprint to 160 countries, the integration-relevant geographic footprint.
• Webex AI Assistant will soon support over 50+ languages, including transcription, summaries, and other AI-powered features that integrate with downstream workflow systems.
• Webex Contact Center scale supports deployments of 50,000+ voice agents, the Suite-level integration ceiling for voice channels.

Cisco Webex Security Incident History (12-Month CVE Rollup)

Cisco PSIRT disclosed two Webex-family vulnerabilities of note across the trailing 12 months: CVE-2025-20236 (Webex App client-side RCE, CVSS 8.8, April 2025) and CVE-2026-20184 (Webex Services SSO impersonation, CVSS 9.8, April 2026). The April 2026 advisory carries the higher severity and broader blast radius, with no available workarounds and a customer-mandatory SAML certificate rotation.

• CVE-2026-20184 carries a CVSS Base Score of 9.8 with severity Critical, rated CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, the higher of the two recent Webex CVEs.
• CVE-2025-20236 carries a CVSS Base Score of 8.8 for the Webex App client-side RCE in earlier desktop versions.
• CVE-2025-20236 affected Cisco Webex App Desktop versions 44.6.0.29928 to 44.7.0.30285 specifically.
• Cisco PSIRT confirmed CVE-2025-20236 had no public announcements or malicious use of the vulnerability described in the advisory as of the advisory date.
• CVE-2026-20184 was first published on April 15, 2026, 16:00 GMT and last updated April 16, 2026, 18:52 GMT, a one-day refinement window.

Worth noting: Cisco’s security advisory confirmed CVE-2026-20184 (CVSS 9.8) had no available workarounds and required affected organizations to upload a new identity provider SAML certificate to Control Hub to avoid service interruption. Cisco itself addressed the vulnerability in Webex Services; the customer-side action was certificate rotation.

CVE-2026-20184: The April 2026 SSO Impersonation Flaw

CVE-2026-20184 is the most severe Webex advisory of the past 12 months. Cisco’s security advisory classified the vulnerability as Critical with a CVSS base score of 9.8, network-attack vector, low complexity, no privileges, no user interaction, and high impact across confidentiality, integrity, and availability. The flaw allowed an unauthenticated, remote attacker to impersonate any user within the service due to improper certificate validation in SSO integration with Control Hub.

• The advisory ID is cisco-sa-webex-cui-cert-8jSZYhWL with CVE identifier CVE-2026-20184.
• The vulnerability allowed an unauthenticated, remote attacker to impersonate any user within the service due to improper certificate validation.
• Cisco’s security advisory noted there are no workarounds that address this vulnerability; remediation requires customer SAML certificate rotation.
• Cisco addressed the vulnerability in Webex Services, with customer-side action limited to uploading a new IdP SAML certificate to Control Hub.
• The CVSS vector was CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, the highest-severity vector class.

For cybersecurity attack data on the broader pattern of SSO and certificate-validation flaws across enterprise SaaS, the CVE-2026-20184 disclosure offers a concrete recent example with full PSIRT documentation.

Is Webex secure after the 2026 vulnerability?

Cisco’s security advisory addressed CVE-2026-20184 in Webex Services on the April 15-16, 2026 advisory window, with the customer remediation limited to uploading a new IdP SAML certificate to Control Hub; for the related CVE-2025-20236 Webex App advisory, Cisco PSIRT stated it was not aware of any public announcements or malicious use of the vulnerability. Helps reduce the attack surface, but it does not guarantee zero risk. Affected organizations following Cisco’s certificate rotation guidance materially reduced the impersonation risk; organizations skipping the rotation remained exposed until they completed it.

Webex Reliability and Outage Track Record

One publicly-named Webex Calling reference is a retailer migration of more than 1.4 million users across 4,600+ locations running at 99.999% availability; Cisco’s own internal Webex Calling rollout covers more than 84,000 employees. SQ Magazine’s analysis of Apple’s customer loyalty patterns shows ecosystem lock-in predicts retention better than satisfaction alone; a similar dynamic applies to Webex’s enterprise reliability commitments inside multi-product Cisco contracts.

• Cisco supported one of the world’s largest retailers in a Webex Calling migration running at 99.999% availability across more than 4,600 locations and more than 1.4 million users.
• Cisco’s internal Webex Calling deployment serves over 84,000 employees as the secondary reliability reference.
• Combined Cisco calling reaches more than 50 million users worldwide across both cloud and on-premises platforms, and the broader installed base is subject to similar reliability targets.

Conclusion

Webex Calling powers more than 18 million users across 195+ markets, sitting inside Cisco’s broader, more than 50 million-user combined calling installed base and a Collaboration segment that booked $4,154 million in fiscal 2025, up year over year. The platform’s enterprise positioning rests on Webex Suite seat-license bundles for Calling, Contact Center (up to 36,000 agents), and AI Assistant plus AI Agent capabilities that early adopters report cutting self-service operational costs by 31%.

The Q3 FY25 to Q1 FY26 segment trajectory, +4% year over year, +2% year over year, –3% year over year, is the watch-line for the next two quarters: Cisco named Devices and WebEx as the Q1 FY26 drag with CPaaS partly offsetting, and the next earnings cycle will tell whether the deceleration reverses or extends. CVE-2026-20184, the April 15, 2026, SSO impersonation advisory rated CVSS 9.8, requires customer-side SAML certificate rotation to Control Hub.
