Log retention isn't just a storage problem. It's a visibility problem.

Without a clear strategy, organizations face:
↳ Skyrocketing storage costs
↳ Alert fatigue from low-signal data
↳ Slow incident response during investigations

The fix? A tiered approach:

🔥 Hot storage — active monitoring, security alerts, auth logs
🌤️ Warm storage — recent historical events, compliance logs
💧 Data Lake — enriched, normalized logs routed for cost-effective long-term querying
❄️ Cold storage — long-term archives, legal holds, regulatory records

Each tier serves a purpose. The goal is keeping the right data, at the right cost, for the right amount of time.

A solid log retention policy also means:
✔ Clear data classification
✔ Automated lifecycle management
✔ Encryption and least-privilege access
✔ Legal hold exceptions built in

We just published a guide covering everything you need to build a cost-effective log retention strategy — from policy frameworks to storage architecture.
