8 Security Dinosaurs and What Filled Their Footprints

Cybersecurity technology is always evolving because the bad guys zig when defenders zag, and new technology and infrastructure is the name of the game in IT, constantly forcing tech revisions on the defensive front. Given this fundamental state of flux, it should come as no surprise that the security world is full of tech dinosaurs on the route to extinction, typically in one of two major fashions.
