Security leaders today are rethinking email security, not because traditional methods have failed outright, but because the threat landscape and business needs have evolved beyond what legacy approaches can handle.<\/p>\n
A surprising but apt analogy keeps surfacing: email security is stuck where antivirus (AV) was a decade ago, and it\u2019s time it evolved like AV did, into an element of EDR.<\/p>\n
The comparison might not be obvious at first. After all, email and endpoints seem like apples and oranges.<\/p>\n
But when you look deeper, especially at the way EDR (Endpoint Detection and Response) grew from the core of AV, the parallel becomes impossible to ignore. Understanding that evolution offers a roadmap for what\u2019s next in email security.<\/p>\n
AV to EDR: A Lesson in Resilience<\/strong><\/p>\n For years, legacy AV promised total protection. The goal was to detect and block every malicious file. If a file looked good, it was allowed. If it matched a known signature of badness, it was blocked. This binary \u201cyes or no\u201d model worked, until it didn\u2019t.<\/p>\n Attackers adapted. Malware became polymorphic. New threats emerged faster than vendors could write signatures. Eventually, the industry had to admit an uncomfortable truth: 100% prevention is impossible.<\/p>\n
