Today’s three largest cybersecurity markets are endpoint security, network security, and
identity. While there are other large cybersecurity markets, including email security, web
security, cloud security, SIEM, and SOC, these three account for over 50% of the cybersecurity
market and are a big part of any organization’s budget.
Today’s cybersecurity solutions are sophisticated and powerful. However, many of them still
operate as individual point solutions. But this is beginning to change. Many vendors have
started integrating their point solutions into a platform that increases interoperability,
simplifies management, and can span today’s hybrid networks.
But this isn’t where cybersecurity started. Like any market or technology, network security has
undergone several cycles of evolution since its inception, especially as critical new functions
and features are developed to support today’s complex networks and to combat increasingly
determined threat actors. Network security has now begun its third era of growth—but where did
it all begin?
