What to look for in a cybersecurity MSP
The most important distinctions between cybersecurity providers are often invisible in sales pitches. A few things worth verifying before shortlisting:
Verification checklist
- Ask for the SOC2 report, not just the certificate. A SOC2 Type II report covers a period of operation under audit. Type I only covers a point in time. Read the exceptions section.
- Test their P1 response time. Call at 2am on a weekend before you sign. How the on-call engineer answers tells you more than any SLA document.
- Ask who your named engineer is. Providers who can't name the person responsible for your environment are routing you through a helpdesk pool, not a dedicated team.
- Check their CMMC or HIPAA experience specifically. General cybersecurity competence does not transfer automatically to regulated frameworks. Ask for a reference in your specific vertical.
