Cybersecurity Services Agency FAQ
Common questions about finding and evaluating cybersecurity services agencies.
What should I look for when hiring a cybersecurity services agency?
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).
How much does it cost to hire a cybersecurity services agency?
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.
How long does a typical cybersecurity services project take?
A penetration test takes 2–4 weeks. A comprehensive security assessment takes 4–8 weeks. SOC 2 or compliance readiness programs take 3–6 months. Incident response should begin within hours.
What are red flags when evaluating cybersecurity services agencies?
Using only automated scanning tools (no manual testing), no clear remediation guidance in reports, certifications that are expired or unverifiable, and making security guarantees (no one can guarantee zero breaches).
How many cybersecurity services agencies are listed on AgencyCluster?
