About Cisco Systems
Cisco Systems, Inc. is the world's largest networking and cybersecurity company, headquartered in San Jose, California. Founded in 1984 by Leonard Bosack and Sandy Lerner, two Stanford University computer scientists, Cisco pioneered the commercialisation of the multi-protocol router — a device that allowed disparate computer networks to communicate using a common language. That foundational innovation established Cisco as the backbone of the modern internet and the enterprise network, a position the company has held and continuously expanded for four decades. Today Cisco generates over $57 billion in annual revenue and employs more than 80,000 people worldwide, serving customers across commercial, enterprise, service provider, and public sector markets in virtually every country on earth.
Cisco's product portfolio spans the full spectrum of enterprise technology infrastructure. In networking, Cisco's Catalyst and Nexus switching platforms are the dominant choice for enterprise campus and data centre networks respectively, while Cisco's ISR and ASR routing platforms form the backbone of wide area networks for hundreds of thousands of organisations globally. Cisco's acquisition of Meraki in 2012 extended its reach into cloud-managed networking, giving it a strong position in the SMB and distributed enterprise market where traditional on-premises management models are being replaced by cloud-first architectures. Cisco's wireless LAN portfolio, built on the Catalyst 9000 series access points and Cisco DNA Center management platform, holds leading market share in enterprise Wi-Fi deployments globally, making Cisco the default choice for organisations building or refreshing campus and branch wireless networks.
In cybersecurity, Cisco has grown into one of the top three security vendors in the world through a combination of organic development and strategic acquisitions. The Cisco Firepower platform — built on the foundation of the SourceFire acquisition in 2013 — delivers next-generation firewall, intrusion prevention, and advanced threat detection capabilities to enterprise and government organisations. Cisco's ASA (Adaptive Security Appliance) remains one of the most widely deployed firewall platforms in existence, with millions of units in active production. Cisco's acquisition of Duo Security in 2018 added market-leading multi-factor authentication, while the acquisition of Umbrella (formerly OpenDNS) provided cloud-delivered DNS security and SASE capabilities. Together these assets make Cisco one of the most comprehensive security platform vendors serving enterprise customers today, with a security portfolio that spans network, endpoint, cloud, identity, and application security.
Cisco's collaboration portfolio was transformed with the relaunch of Cisco Webex as a unified platform covering video meetings, messaging, calling, events, and contact centre capabilities. The COVID-19 pandemic accelerated enterprise adoption of Webex as organisations globally shifted to remote and hybrid working, and Cisco invested heavily in AI-powered features including noise removal, real-time translation, and meeting intelligence. Cisco Unified Communications Manager (CUCM) remains the standard for on-premises enterprise telephony at thousands of large organisations, while Webex Calling represents the cloud successor to that installed base — creating a substantial migration opportunity for partners and technology vendors serving the Cisco collaboration space.
In data centre and cloud infrastructure, Cisco's Unified Computing System (UCS) — launched in 2009 — disrupted the traditional three-tier data centre by integrating compute, networking, and storage access into a single converged infrastructure system. UCS remains a significant presence in enterprise data centres globally. Cisco's acquisition of AppDynamics in 2017 for $3.7 billion gave it a leading application performance monitoring platform, while the acquisition of ThousandEyes in 2020 added internet and cloud network intelligence that is increasingly critical as enterprises move workloads to multi-cloud environments. ELP Data's Cisco Users List gives you direct access to 485,232+ confirmed organisations running Cisco technology in their active infrastructure today, covering all major product lines and every major geographic market.

Recent Developments at Cisco & Enterprise Networking
Key market developments shaping the Cisco installed base and enterprise networking landscape in 2024 and 2025.
Cisco Launches AI-Native Networking with Cisco AI Assistant
Cisco has announced a major push into AI-native networking with the introduction of the Cisco AI Assistant, embedded across its Webex collaboration platform, Cisco DNA Center network management, and Cisco Security Cloud. The AI Assistant is designed to automate routine network operations tasks — including troubleshooting, configuration changes, and anomaly detection — that currently consume significant time from network engineering and IT operations teams. Cisco's investment in AI-driven networking reflects the broader industry shift towards AIOps, where machine learning models monitor network performance, predict failures, and recommend or automatically apply remediation actions without human intervention. For vendors selling AI, automation, or network management solutions into Cisco environments, this transition creates compelling new sales conversations with CIOs and Network Architects evaluating how to modernise their operational tooling. Cisco's large installed base means that any significant product shift at Cisco ripples through hundreds of thousands of enterprise IT organisations simultaneously, creating both opportunity and urgency for complementary technology vendors. The AI networking investment also positions Cisco competitively against cloud-native networking vendors who have been gaining ground in greenfield deployments at technology-first organisations.
Cisco Security Cloud Consolidates Enterprise Cybersecurity Portfolio
Cisco has been executing a multi-year strategy to consolidate its cybersecurity portfolio into a unified Cisco Security Cloud platform, bringing together Cisco Secure Firewall, Cisco Duo MFA, Cisco Umbrella cloud security, Cisco Secure Endpoint, Cisco SASE, and Cisco XDR under a single integrated architecture. This consolidation strategy addresses the growing enterprise demand for platform-based security rather than point solutions, as IT and security teams seek to reduce the complexity of managing dozens of disparate security tools from different vendors. Cisco's position as the network vendor for most large enterprises gives it a significant advantage in delivering security that is tightly integrated with the underlying network infrastructure — an approach increasingly valued as network and security operations converge into unified NOC/SOC functions. The Security Cloud transition is driving significant evaluation activity at Cisco accounts, with CISOs and IT Directors re-evaluating their security stack architecture in light of Cisco's unified platform offer. For cybersecurity vendors and managed security service providers, this transition creates compelling discussions with Cisco customers about complementary security capabilities that sit alongside or integrate with the Cisco Security Cloud.
Cisco Webex Strengthens Enterprise Position with AI-Powered Features
Cisco Webex has made significant gains in the enterprise collaboration market, particularly among large organisations with complex security, compliance, and integration requirements. Cisco's investment in AI-powered collaboration features — including Webex AI Assistant for meetings, real-time transcription and translation in 100+ languages, automated action item extraction, and intelligent noise cancellation — has strengthened Webex's competitive position. Cisco's strategy of delivering Webex as both a standalone cloud service and as an integration layer on top of existing Cisco Unified Communications Manager (CUCM) deployments has enabled gradual migration paths for the large installed base of on-premises telephony customers, many of whom are now in active evaluation of Webex Calling as their cloud telephony successor. For vendors building on the Webex platform — including integration developers, ISVs, and managed service providers — Cisco's growing Webex installed base represents a substantial and expanding addressable market with strong enterprise spending power.
Enterprise SD-WAN Adoption Drives Cisco Meraki and Catalyst SD-WAN Growth
Enterprise adoption of SD-WAN technology continues to accelerate as organisations replace legacy MPLS-based wide area networks with more flexible, cloud-friendly software-defined architectures. Cisco is the leading SD-WAN vendor by installed base, serving this market through both Cisco Meraki SD-WAN and Cisco Catalyst SD-WAN (formerly Viptela). The migration from traditional WAN architectures to SD-WAN is creating a wave of network refresh activity at thousands of enterprise organisations, with CIOs and Network Architects evaluating SD-WAN as part of broader cloud migration and hybrid work infrastructure projects. Cisco's SD-WAN growth is also being driven by the convergence of SD-WAN with SASE, as organisations seek to combine network connectivity and security into a single cloud-delivered service. For managed service providers, network security vendors, and cloud connectivity specialists, the SD-WAN transition within the Cisco installed base represents one of the largest near-term sales opportunities in enterprise networking, with most large enterprises now in active evaluation or early deployment phases.

Why This List Matters for B2B Marketing
Cisco's installed base represents one of the largest and most commercially valuable audiences in enterprise technology. With 485,232+ verified organisations running Cisco products across networking, security, collaboration, data centre, and cloud infrastructure, the Cisco ecosystem is not a niche market — it is the foundational technology layer for a significant proportion of the world's enterprise IT infrastructure. Any vendor whose product integrates with, complements, or displaces a Cisco technology is operating in an addressable market that spans hundreds of thousands of organisations globally and reaches into virtually every industry vertical and geographic market.
Cisco's current transition from hardware-centric networking to software, cloud, and subscription-based models is creating an extraordinary level of buying activity within its installed base. Organisations that deployed Cisco hardware five or ten years ago are now evaluating whether to refresh with new Cisco hardware, migrate to Cisco's cloud-managed platforms, or consider alternative networking and security vendors. This transition — driven by Cisco's push towards subscription licensing, its Meraki cloud-managed platform, and its Security Cloud consolidation strategy — is generating active evaluation cycles at thousands of enterprise IT organisations simultaneously, creating a multi-year wave of procurement activity that benefits any vendor positioned in the Cisco ecosystem.
The Cisco installed base is also highly valuable for cybersecurity vendors. Cisco's dominant position in network infrastructure means that Cisco network devices — switches, routers, firewalls — are present in the vast majority of enterprise networks. Security vendors whose products integrate with Cisco infrastructure, consume Cisco telemetry, or provide capabilities that complement Cisco's security portfolio have a natural sales motion into Cisco accounts. Network Detection and Response vendors, SIEM platforms, threat intelligence providers, and zero-trust access vendors all benefit from reaching Cisco infrastructure owners who are already investing heavily in network security and are receptive to complementary capabilities that extend their existing Cisco security investments.
