What do F5, SonicWall, and Salesloft Drift have in common? They're all cybersecurity vendors that got breached in 2025. And nobody noticed for weeks!
Mandiant's 2026 data shows the average intrusion sits undetected for 14 days. In espionage cases, it's 122.
The warning signs are almost never dramatic. They're things your team already sees but doesn't flag:
π A password reset for someone on holiday
π An "alert closed as routine" that never got a second look
π A service account querying tables it's never touched
π Backup jobs finishing suspiciously fast or failing quietly
π An OAuth app connected by someone in marketing, months ago
None of these require new tools. They require someone whose job is to notice.
