Service

Managed SIEM & Log Management

A SIEM is only as good as the sources feeding it and the people tuning it. We design, deploy, and run your SIEM — onboarding the log sources that matter, engineering high-signal detections, and keeping costs predictable.

What you get

  • Deployed and documented SIEM architecture
  • Managed detection rule set with monthly tuning
  • Quarterly source coverage and cost review

Outcomes

What changes for your team

  • Log sources prioritized by risk, not by what was easy to connect
  • Detections tuned so analysts chase real threats, not noise
  • Retention and searchability aligned to your compliance obligations
  • Predictable ingest costs instead of surprise invoices

Inside the service

What's included

Architecture & onboarding

Source prioritization, parsing, and normalization across cloud, identity, endpoint, and network telemetry.

Detection content

A managed rule set mapped to MITRE ATT&CK, tuned continuously against your environment's baseline.

Cost & health management

Ingest monitoring, source health alerts, and retention tiering so the platform stays fast and affordable.

Compliance-ready reporting

Log retention and audit evidence aligned to frameworks like SOC 2, HIPAA, and PCI DSS.

Is this you?

Signs this is the right starting point

  • You bought a SIEM and it became an expensive log bucket
  • Auditors keep asking for log evidence you can't produce quickly
  • Your team spends more time tuning rules than investigating
