Managed SIEM Compliance Evidence Checklist: NIS2 and DORA
A SIEM can detect every incident and still leave gaps in the evidence an auditor will ask for. This checklist helps you find those gaps before a review does.
- NIS2 and DORA evidence requirements checklists
- Log retention and evidence verification worksheet
- Evidence readiness scoring and gap inventory
SIEM evaluations focus on detection. Audits focus on documentation.
Neither NIS2 nor DORA requires a specific SIEM platform. Both require you to demonstrate what your monitoring produced during an incident.
What's inside the Managed SIEM Compliance Evidence Checklist
NIS2 evidence requirements checklist
Assess whether your SIEM supports log retention, incident documentation, and reporting evidence requirements under NIS2.
DORA evidence requirements checklist
For financial entities in scope: ICT incident classification, investigation records, business impact documentation, and audit trail requirements.
Log retention & verification worksheet
Map current retention periods against regulatory requirements across endpoint, authentication, firewall, cloud, application, and email logs.
Compliance evidence gap inventory
Document and prioritize gaps by evidence area, business impact, and owner — not every gap carries the same risk.
Evidence readiness scoring worksheet
Score your evidence readiness across both frameworks and get a rating: High risk, Developing, Established, or Audit-ready.
Readiness rating & improvement guide
Interpret your score and identify priority actions before the next audit cycle.
Your SIEM detected the incident. Could you prove it six months later?
The security controls worked. Find out if the paper trail would too — before a review asks the same question.

A managed SIEM optimized for one is not automatically capable of the other. A SIEM can score well on every metric on the left and still fail an audit on the right.
Why evidence readiness matters under NIS2 and DORA
NIS2 notification timeline
Significant incidents require an early warning within 24 hours and a detailed notification within 72 hours — grounded in incident timelines, impact assessments, and response actions.
DORA incident classification
Financial entities must classify ICT incidents using documented criteria. Undocumented or inconsistent classification is a finding on its own.
Investigation records
Both frameworks expect investigation activities to be documented and retained. A well-functioning SOC that keeps no investigation records still fails the evidence standard.
Audit trail requirements
DORA mandates audit trails for critical systems and administrative actions. NIS2 expects authentication and access activity to be logged and searchable.
Frequently asked questions
What is compliance evidence in a managed SIEM context?
The records an auditor will actually ask for: incident timelines, investigation notes, containment decisions, recovery actions, and proof that logs were retained according to policy. Detection alerts are not evidence — documentation of what happened after the alert is.
Does NIS2 require a specific SIEM platform?
No. It requires outcomes: monitoring, incident detection, and records that support regulatory reporting. How you get there is your call. A managed SIEM is the most common way organizations produce that evidence.
What does DORA require for ICT incident documentation?
Classification using documented criteria, investigation records, business impact documentation, and audit trails for critical systems. The practical gap most organizations discover is that the records exist somewhere but can't be produced quickly when requested.
What's the difference between detection readiness and evidence readiness?
Detection readiness is your ability to identify threats. Evidence readiness is your ability to prove what happened. A SIEM can score well on the first and still fail an audit on the second.
How long does this assessment take?
30 to 45 minutes for the checklists and scoring. Longer if pulling a real incident record for the evidence availability test reveals that the documentation is harder to locate than expected — that delay is itself a useful finding.
Evaluating a managed SIEM provider?
Most evaluations test detection. Few test evidence production. Q-Sec helps organizations add an audit-readiness dimension to their SIEM strategy, before, during, and after a provider evaluation.
