SENTRY — SIEM-as-a-Service

Managed SIEM, Without the In-House Tuning Burden

A SIEM is only as good as the people tuning it. SIEM-as-a-Service delivers log collection, correlation, and detection engineering as a managed capability — so alerts reflect real risk instead of noise nobody has time to fix.

The Problem With Self-Managed SIEM

A SIEM Is a Platform. Detection Is a Practice.

Standing up a SIEM is a licensing and integration exercise. Getting useful signal out of it — tuned detection rules, low false-positive rates, current threat coverage — is an ongoing discipline that most internal IT teams don’t have the bandwidth to sustain alongside everything else on their plate.

Left untuned, a SIEM produces exactly what it was built to produce: a very large number of alerts. Without dedicated detection engineering, that turns into alert fatigue — the exact failure mode that lets real incidents get missed inside the noise.

Managed SIEM (SIEM-as-a-Service) puts the collection, correlation, tuning, and detection-content maintenance on a provider whose job is specifically to keep signal-to-noise workable — as an ongoing practice, not a one-time deployment.

What’s Included

Log source onboarding

Ingestion configured across endpoints, network devices, cloud platforms, identity providers, and applications.

Correlation & tuning

Detection rules mapped to real attacker techniques and continuously tuned against your actual environment, not a generic template.

Retention & compliance

Log retention configured to the requirements of frameworks like HIPAA, PCI-DSS, SOC 2, and CMMC 2.0.

Migration support

Historical data and existing detection use cases can typically be migrated from an existing SIEM with the provider owning the cutover.

Frequently Asked Questions

Can managed SIEM replace our current platform?
In most cases, yes. Historical data and existing detection use cases can be migrated, and the new environment operated going forward — see our SOC-as-a-Service overview for the broader monitoring context this sits inside.
Is SIEM-as-a-Service the same as MDR?
No. SIEM-as-a-Service is the log collection and detection layer; MDR is the broader managed response service that typically consumes SIEM (and EDR/XDR) data as its input. See MDR vs. EDR vs. XDR.
How does this support 24/7 monitoring?
Managed SIEM is the data layer that a 24/7 SOC monitors against — the two are usually delivered together, not separately.
