Our Services

Fractional leadership. AI-driven operations. Automated compliance. In a single monthly engagement.

The Delivery Model

One provider. Named accountability.

Traditional MSSPs sell tool licenses and call it a service. Aetos One assigns named security leaders who own your program outcomes at every tier.

01
Fractional Leadership
A named CISO or DPO owns your security program. Not a ticket queue.
02
AI-Native Operations
AI SOC platform integrates with your existing stack to triage and respond 24/7.
03
Compliance Automation
Compliance automation platform keeps your controls current and audit evidence organized across frameworks.
