• Recommended for: Organizations that already standardize on FortiGate / Fortinet Security Fabric and want to “bolt on” a turnkey SOCaaS rather than build their own SOC or integrate a third-party MDR stack.

How should you choose a SOCaaS provider in USA? 

Start by defining your baseline: data sensitivity, in-house skills, tech stack, and acceptable risk. Then choose SOCaaS providers using clear, verifiable criteria rather than marketing claims. 

Prioritise vendors that: 

• Prove 24×7 coverage with US-aligned SLAs, named contacts, and mean time to detect/respond measured in minutes, not hours.  
• Prioritise mssp companies in USA that already protect organisations with similar size, industry, and tech stack, and confirm they deliver US-hours threat hunting, incident response, and executive-ready reporting rather than basic alert forwarding. 
• Integrate cleanly with your existing EDR, firewalls, cloud platforms, and ticketing so the managed security services SOC function can act on your environment from day one. 
• Demonstrate experience with US regulations (HIPAA, PCI DSS, SOX, state privacy laws) and provide audit-ready reports, not just alert feeds. 
• Offer transparent runbooks that show exactly what they will contain, escalate, or remediate—and what still depends on your team. 
• Publish third-party attestations (SOC 2, ISO 27001) and customer references from US organisations of a similar size and industry. 
• Operate as a true managed security service provider, with clear ownership of detection and response outcomes, not just tool hosting or log collection.
