How to choose a cybersecurity services provider
Cybersecurity services divide into four distinct buying categories that rarely share the same vendor: managed detection and response (MDR/SOC), penetration testing and offensive security, incident response retainers, and cyber risk advisory. Bundling reduces switching costs but concentrates risk; many CISOs deliberately split offensive testing and managed SOC across separate firms to avoid grading their own homework.
For incident response retainers, Mandiant, CrowdStrike Services, and Kroll dominate North American breach response volume. European buyers should also evaluate NCC Group and Secureworks for regional availability. Retainer pricing is now standardised: typical retainer fees run $50k-$250k annually for guaranteed response SLAs, with hourly engagement rates of $400-$800 for IR consultants. A no-retainer engagement during an active breach can run 3-5x the retained rate.
For ongoing managed SOC, evaluate alongside SIEM platforms and XDR platforms to understand which detection content the provider can deliver. For broader security architecture advisory see identity and security consulting, and for ongoing compliance see IT governance and compliance. Pen testing buyers should require CREST or equivalent accreditation and named-tester CVs.
Frequently Asked Questions
How much does a managed SOC cost for a mid-sized enterprise?
Managed SOC pricing for a 3,000-employee enterprise: $400k-$1.5M per year. Co-managed models (where the customer keeps tier 1 in-house and outsources tier 2/3) typically run 30-40% less than fully outsourced models. Pricing is driven by ingested log volume (EPS or GB/day) and the supported toolset.
What is the difference between an incident response retainer and ad-hoc IR?
An IR retainer guarantees response SLAs (usually 2-4 hour kick-off) and locks in hourly rates. Ad-hoc IR engagement during a live breach commonly runs 3-5x the retained rate and may face delays of days during peak periods. For any organisation processing regulated data, a retainer is now considered baseline.
How do we evaluate penetration testing providers?
Look for: CREST or OSCP-equivalent certifications at the team level, named-tester CVs (not just firm credentials), sample reports with technical depth, and clear methodology aligned to MITRE ATT&CK. Continuous testing platforms (PTaaS) are emerging as an alternative to annual point-in-time tests.
Should we use a Big Four or pure-play security firm?
Big Four firms (Deloitte Cyber, PwC, KPMG, EY) excel at board-level advisory, cyber transformation, and integrating with broader risk frameworks. Pure-play firms (Mandiant, CrowdStrike Services, NCC Group, Bishop Fox) lead on technical depth for IR, threat hunting, and offensive testing. The two are usually complementary, not substitutes.
How do we measure SOC effectiveness?
Key metrics: mean time to detect (MTTD) under 24 hours for known threats, mean time to respond (MTTR) under 4 hours for confirmed incidents, true-positive rate above 60%, and coverage of MITRE ATT&CK techniques relevant to the industry. Require quarterly purple-team exercises to validate detection content. See SOC metrics benchmark for details.
