Managed SIEM
Transform overwhelming log data into high-fidelity, actionable security alerts.
Book AssessmentIntelligent Log Orchestration & Compliance Monitoring
Security Information and Event Management (SIEM) platforms are powerful but notoriously difficult to maintain. Without constant tuning, they generate thousands of false-positive alerts a day, burying real threats in white noise. Atgardas Managed SIEM services take the burden off your internal team.
Our engineers deploy, host, and continuously tune elite cloud-native SIEM architectures (like Microsoft Sentinel or Splunk). We aggregate logs from your firewalls, identity providers, cloud infrastructure, and endpoints into a single, correlated pane of glass.
We author custom detection logic tailored to your specific business operations, ensuring that when an alert fires, it warrants immediate investigation by our integrated 24/7 SOC.

We primarily support Microsoft Sentinel, Splunk, and Elastic Security, though we adapt to others.
We offer both models. We can co-manage your existing on-premise SIEM or host entirely cloud-native solutions.
Log management just stores data. A SIEM uses complex logic to correlate disparate logs to identify an attack chain.
Yes, we heavily filter useless 'chatter' logs at the source to save you massive ingestion fees.
Yes, nearly all modern security frameworks require centralized, tamper-proof logging with defined retention periods.
MDR handles endpoint events; SIEM handles everything else (firewalls, O365, VPNs). They work best together.
Absolutely. We operate with full transparency, providing you with real-time dashboard access.
Yes, Custom Detection Engineering is a core part of our ongoing management.
