Cybersecurity

Cybersecurity covers the software, services, and technology that protect systems, networks, data, and identities from threats — spanning endpoint, network, cloud, application, and identity security, plus the managed services and consulting that operate and advise on defense. It is one of the largest, fastest-growing, and most resilient technology categories, with security spending treated as non-discretionary even in downturns.

Demand is driven by escalating threats (ransomware, nation-state attacks, supply-chain compromises), cloud migration, AI (both a new threat and a defensive tool), tightening regulation, and a chronic shortage of security talent. It is the most active arena in technology M&A and venture capital — mega-deals like Google's acquisitions of Mandiant and Wiz and Cisco's purchase of Splunk, alongside Thoma Bravo's serial roll-ups — with the market consolidating toward platforms even as best-of-breed point solutions proliferate.
