When I started working in cybersecurity 20 years ago, there were a few rock-solid security technology principles treated as gospel. One of those was the insistence on best-of-breed security technologies. Those of you working in security in the early 2000s may remember installing independent firewall and antivirus software on every endpoint.
Best-of-breed technologies were then combined as part of another time-honored principle—defense-in-depth. In theory, best-of-breed technologies would complement one another for incremental security protection.
During the intervening years, the best-of-breed mentality was imbued within cybersecurity culture, while individuals and groups closely protected their preferred technologies. Your organization was a McAfee or Symantec shop and used Check Point, Cisco, or Fortinet firewalls. Security “server huggers” saw any suggestion of change as blasphemy.
