SIEM Monitoring as the Operational Core of DORA Compliance

DORA Articles 10 and 17 require financial institutions to connect all critical-function ICT systems to a SIEM, detect and classify security events in real time, and escalate incidents within regulatory timeframes (4-hour initial notification, 24-hour follow-up). Operationally excellent SIEM goes beyond compliance: it delivers measurable detection times (MTTD), automated response playbooks, and complete audit trails for DORA supervisory reviews.

We support you in implementing and optimizing SIEM solutions that provide comprehensive visibility into your security posture while meeting DORA requirements. Our approach combines technical expertise with deep regulatory knowledge to create monitoring capabilities that are both effective and compliant.

6 QUESTIONS, BRIEFLY ANSWERED

Frequently asked questions about DORA SIEM Monitoring

What SIEM requirements follow from DORA?

DORA doesn't mandate a specific SIEM product, but under Articles 10 and 17 it requires continuous detection of ICT incidents and their timely reporting. A SIEM system is, in practice, the most common technical means of actually operationalizing this real-time monitoring and anomaly detection requirement.

How does SIEM specifically support DORA incident reporting obligations?

A well-configured SIEM provides the timestamps and details needed for a timely initial notification within DORA's reporting deadlines, as well as the forensic data needed for the later final report. Without consistent logging, the level of detail a DORA incident report requires often can't be assembled in time.

Which log sources need to be connected for DORA-compliant monitoring?

Priority goes to systems critical to core business functions: network infrastructure, access control systems, critical applications, and interfaces to key ICT third-party providers. Connecting every single system is rarely realistic and usually unnecessary; prioritization should follow the criticality assessment from ICT risk management.

Is an existing SIEM system sufficient, or is a DORA-specific extension needed?

An existing SIEM can provide the technical foundation but often needs adjusted alerting rules and classification logic so incidents get automatically evaluated against DORA's criteria for "major" incidents. Without that adjustment, the system detects technical anomalies but doesn't automatically sort them into the category relevant for reporting obligations.

How is SIEM monitoring effectiveness demonstrated for DORA purposes?

Evidence typically comes from documented test scenarios where simulated incidents are actually detected and correctly escalated, along with an evaluation of how quickly real or simulated events were detected historically. A SIEM that has never been tested against realistic scenarios provides no solid evidence of effectiveness in an audit.

Which providers or service partners support SIEM buildout specifically for DORA?

What matters less is the SIEM product brand and more the provider's experience configuring rules around DORA's specific reporting deadlines and incident categories. When selecting one, it's worth checking whether the provider has already supported comparable financial entities through a DORA-compliant SIEM rollout, rather than bringing only general SIEM expertise without regulatory context.
