SIEM Selection Guide: 10 critical Criteria (2026)

The market is crowded: cloud-native, open source, legacy vendor. Writing an RFP without asking the right questions is expensive.

10 criteria

1. Log source support — do you have FortiGate/MikroTik/AD?
2. Correlation quality — ready-made use-case vs writing from scratch
3. False positive payload — measure in the pilot period
4. TCO — license + storage + operations staff
5. Data location — KVKK, on-site or in the cloud?
6. A.I. approach — is data getting out?
7. Reporting — admin and audit PDF
8. 5651 / KVKK — is there a ready package?
9. Scale — Performance as EPS increases
10. Support language — Turkish documentation and SLA
