Top 10: Network Security Vendors
Project Glasswing – Anthropic’s initiative to secure the world’s most critical software across tech providers like AWS, Broadcom, Cisco, CrowdStrike and more – marks a turning point in the digital arms race by uniting industry titans to defend against AI vulnerabilities.
As autonomous attack chains collapse the window between discovery and weaponisation, human defenders face an unprecedented speed asymmetry.
Security is no longer just a priority but a survival imperative – and these 10 network security vendors are leading the charge.
10: Akamai
Revenue: US$4.21bn (annual revenue in 2025)
Employees: 11,300+
CEO: Dr Tom Leighton
Founded: 1998
This year, Akamai is leading the market in distributed denial of service mitigation and API security, leveraging its edge network to stop threats before they reach the data centre.
The company’s focus on zero-trust network access and microsegmentation makes it a favourite for enterprises with highly distributed workforces that require low-latency security enforcement without sacrificing application performance.
“In the past week, I’ve received questions about what several announcements from AI frontier company Anthropic could mean to AI-optimised cloud infrastructure and cybersecurity providers,” writes Dr Tom Leighton, CEO of Akamai on LinkedIn.
“Are these a replacement for traditional cloud and CDN infrastructure? Does AI that can autonomously discover and exploit software vulnerabilities threaten Akamai’s business, or make what we do more important? We believe this makes Akamai more important than ever.
9: Check Point Software
Revenue: US$2.73bn (Q4 2025)
Employees: 7,000+
CEO: Nadav Zafrir
Founded: 1993
Check Point prioritises a “prevention-first” philosophy.
Its Infinity Platform has evolved to utilise a hybrid mesh architecture, unifying security across on-premises, cloud and IoT environments.
Known for high-efficacy threat intelligence via Check Point Research, the firm offers some of the most granular firewall policies in the industry.
It is currently leading the charge in securing AI-driven workflows, preventing data leakage within corporate Gen AI applications.
8: Juniper Networks (HPE)
Revenue: US$5.2bn (2025, according to Companies Market Cap)
Employees: 10,000
CEO: Rami Rahim
Acquired by Hewlett Packard Enterprise: 2025
Now a part of the Hewlett Packard Enterprise (HPE) ecosystem, Juniper Networks excels in AI-native networking.
Its security strategy is built around the Mist AI engine, which automates threat detection and network self-healing.
By integrating security directly into the fabric of the network, Juniper reduces the security tax on performance.
It is the go-to choice for organisations prioritising high-speed, automated operations and a connected security approach.
7: Cloudflare
Revenue: US$2.61bn
Employees: 5,000
Co-founder and CEO: Matthew Prince
Founded: 2009
Cloudflare has redefined the security service edge by making complex protection accessible at machine speed.
Its global network now blocks more than 200 billion attacks daily, using virtual patching at the edge to protect legacy systems from zero-day exploits.
Cloudflare’s One platform is a dominant force in shadow AI governance, providing visibility and control over unsanctioned AI tools that employees introduce into the corporate environment.
6: Broadcom (Symantec)
Revenue: US$19.3m (Q1, 2026)
Employees: 10,000+
CEO: Hock E. Tan
Founded: 1961
Following the integration of Carbon Black and Symantec, Broadcom has launched Symantec CBX, a unified XDR platform designed to provide enterprise-grade security with reduced complexity.
By consolidating endpoint, network and email telemetry into a single AI-driven interface, Broadcom is targetting mid-to-large enterprises that need massive defensive power without an army of analysts.
The firm’s focus remains on high-end data loss prevention (DLP) and protecting the global software supply chain.
5: Zscaler
Revenue: US$719.2m (Q4, 2025)
Employees: 10,000
CEO: Jay Chaudry
Founded: 2007
A pioneer of the Zero Trust Exchange, Zscaler continues to dominate the secure-access-service-edge market by completely decoupling security from the physical network.
It has moved beyond simple web auditing to AI-powered data protection, using machine learning to classify sensitive data in real-time as it moves to the cloud.
Zscaler’s direct-to-app connectivity model eliminates the need for traditional VPNs, significantly reducing the lateral movement risks that plague legacy flat networks.
Jay Chaudry, CEO of Zscaler, says: “Traditional defenses like VPNs and firewalls leave doors open for AI to pick. To survive, you must eliminate your attack surface entirely. You must ‘go dark’ by removing your applications from the open internet.
“Zscaler’s Zero Trust Exchange was built for this exact speed and scale: connecting users to apps, not networks and removing your business from an attacker’s line of sight.”
4: CrowdStrike
Revenue: US$5bn (FY2026)
Employees: 10,000+
CEO: George Kurtz
Founded: 2011
CrowdStrike’s Falcon Platform is now a central nervous system for network security.
Its 2026 updates focus on threat-informed cloud risk prioritisation, mapping adversary behaviour directly to network vulnerabilities.
By combining identity protection with automated response, CrowdStrike can stop breaches in record time.
Its single-agent architecture remains its greatest competitive advantage, providing deep visibility across the network, cloud, and endpoints without the usual performance overhead.
3: Fortinet
Revenue: US$6.8bn (2025)
Employees: 10,000+
CEO: Ken Xie
Founded: 2000
Fortinet’s strength lies in its Security Fabric, which integrates over 50 products into a single, cohesive ecosystem.
Its proprietary application-specific integrated circuit technology allows its firewalls to process encrypted traffic at speeds that software-only competitors struggle to match.
Fortinet is the leader in the convergence of networking and security, offering a price-to-performance ratio that makes it the preferred vendor for branch offices and distributed retail environments globally.
2: Cisco
Revenue: US15.3bn (Q2, FY2026)
Employees: 10,000+
Chair and CEO: Chuck Robbins
Founded: 1984
Cisco has successfully integrated Splunk into its Cisco Security Cloud, creating a massive telemetry engine that provides unmatched visibility.
Its hypershield technology introduces AI-native security that can automatically shield vulnerable workloads in milliseconds.
By leveraging its dominance in hardware (Catalyst and Nexus), Cisco embeds security directly into the silicon, making the network itself a sensor and an enforcer across hybrid-cloud and multi-cloud architectures.
1: Palo Alto Networks
Revenue: US$2.6bn (Q2 FY2026)
Employees: 10,000+
Chairman and CEO: Nikesh Arora
Founded: 2005
Palo Alto Networks holds the top spot thanks to its aggressive platformisation strategy and the launch of Precision AI.
This system goes beyond basic automation, using agentic AI to autonomously investigate and patch network vulnerabilities without human intervention.
The firm’s Strata, Prisma and Cortex pillars offer a complete, integrated stack that secures everything from the hardware firewall to the most remote cloud container, effectively ending the era of disconnected “point products” in cybersecurity.
“The fastest AI-assisted attacks are already moving from access to exfiltration in 25 minutes, while the average enterprise still takes days to detect an intrusion,” says Nikesh Arora, Chairman and CEO of Palo Alto Networks.
"These numbers were already uncomfortable. The new frontier models will make them untenable. The question I hear most often is: Now what?
"The key lies in the fact that the same models that find and exploit vulnerabilities can also be part of the defense, but only if they are quickly integrated into defensive solutions."
