Check their certifications (OSCP, CISSP, CEH) and whether their team has disclosed responsible vulnerabilities. Ask about their methodology (OWASP, NIST, PTES). For penetration testing, ask if they provide detailed remediation guidance, not just vulnerability lists. Check if they have experience with your industry's compliance requirements (HIPAA, SOC 2, PCI DSS).

Penetration testing engagements cost $10K–$60K depending on scope. Security assessments and compliance readiness range from $20K–$100K. Managed security retainers (continuous monitoring, incident response) run $5K–$30K/month.
