A Microsoft-native SOC built for reality

The SOC your Microsoft stack deserves.

Alexein is a 24x7 Security Operations Centre delivered as-a-service, built natively within the Microsoft security ecosystem.

Powered by Microsoft Sentinel, Defender XDR, Entra ID and Purview, Alexein continuously monitors your environment, triages alerts within minutes, and contains threats using pre-approved, controlled actions.

We don’t replace your Microsoft investment. We operationalise it.

From detection to outcome – we identify it, analyse it, contain it where safe, 
and clearly show the impact.

Data rich. Action poor.

Security tools don’t stop threats.
Operational clarity does.

Most organisations already own powerful Microsoft security tools.

What they don’t have is:

24x7 monitoring coverage

Consistent triage discipline

Clear containment guardrails

Defined escalation pathways

Documented audit trails

Time to investigate every alert

The result?

Alert fatigue. Slow response times. Unclear accountability. Unmeasured risk exposure.

Alexein closes that gap.

Structured. Measured. Predictable.

Outcomes that matter.

Different by design.

Alexein operates directly inside your Microsoft tenant.

We do not move your data out of your Microsoft tenancy.
We do not operate a black-box SIEM.
We do not replace your Microsoft security stack.

We enhance it. We operationalise it. We make it accountable.

Smarter security starts with clarity.
