Picture this: you've hardened every laptop in your fleet with real‑time telemetry, rapid isolation, and automated rollback. But the corporate mailbox—the front door for most attackers—is still guarded by what is effectively a 1990s-era filter. This isn't a balanced approach. Email remains a primary vector for breaches, yet we often treat it as a static stream of messages instead of a dynamic, post-delivery environment. This environment is rich with OAuth tokens, shared drive links, and years of sensitive data. The conversation needs to shift. We should stop asking, "Did the gateway block the bad thing?" and start asking, "How quickly can we see, contain, and undo the damage when an attacker inevitably gets in?" Looking at email security through this lens forces a fundamental shift toward the same assume-breach, detect-and-respond mindset that already revolutionized endpoint protection. The day the wall crumbled Most security professionals know the statistics. Phishing and credential theft continue to dominate breach reports, and the financial impact of Business Email Compromise often outweighs ransomware. But the data tells a more interesting story, one that mirrors the decline of legacy antivirus. A decade ago, AV was good at catching known threats, but zero-day exploits and novel malware slipped past. Endpoint Detection and Response (EDR) emerged because teams needed visibility after an attacker was already on the machine. Email is following the same script. Secure Email…Read More
