Your server logs are screaming warnings — are you listening? Learn the 5 sneaky patterns that expose attackers before they own your SaaS.

Security Tip
1
Monitor for repeated 401/403 errors from a single IP — this screams brute force or credential stuffing.
2
Alert on sudden spikes in 500 errors — attackers probing your app logic will trigger backend failures.
3
Watch for abnormally slow request rates from one source — low-and-slow attacks dodge rate limiters by design.
4
Flag unusual user-agent strings in logs — bots and scanners rarely pretend to be Chrome convincingly.
5
Set up automated log parsing with tools like GoAccess, Fail2Ban, or a SIEM so threats surface in real time.
