The Firewall Company That Bet Everything on the Middle
For 30 years, WatchGuard has sold security to the companies too small for Palo Alto and too serious to go without - and built its whole business around the partners who install it.
WireX Systems
WireX Systems is a cybersecurity company building network detection and response (NDR) and forensics technology under its EvidenceOps platform, powered by Ne2ition. Its patented Contextual Capture engine translates raw network packets into human-readable intelligence, retaining months of full payload data so security teams can investigate, prove, and respond to threats in minutes instead of days. Founded in 2010 by veterans of Israel's intelligence community, the company serves SOC teams across finance, healthcare, manufacturing and retail.
Vectra AI
Vectra AI is a San Jose-based cybersecurity company that uses artificial intelligence to detect, investigate, and stop active cyberattacks across hybrid and multi-cloud environments. Its platform - built around what the company calls Attack Signal Intelligence - watches network, identity, public cloud, and SaaS behavior to surface real attacks in progress while filtering out the noise that overwhelms security teams. Founded in 2011 and led by CEO Hitesh Sheth, Vectra has raised roughly $425M, reached a $1.2B valuation, and was named a Leader in the 2026 Gartner Magic Quadrant for Network Detection and Response.
Corelight
Corelight is a San Francisco-based cybersecurity company that pioneered the commercial Open NDR (Network Detection and Response) platform, built on Zeek - the gold-standard open-source network security monitor created by co-founder Dr. Vern Paxson at Lawrence Berkeley National Lab. By transforming raw network traffic into high-fidelity, structured logs and pairing them with AI-powered analytics, Corelight gives enterprise security teams and government agencies the evidence they need to detect, investigate, and respond to threats faster. With $309M in total funding, 40%+ ARR growth, and recognition as a Gartner Magic Quadrant Leader for NDR, Corelight is widely regarded as the most trusted platform for network-based threat detection.
