The CISO's Guide to Managed Security Operations
Security evaluation framework for assessing managed security service providers. Threat detection, incident response, compliance management, and security program maturity.
Key Questions CISOs Ask
Critical security concerns when evaluating managed security service providers
How do you handle threat detection and response?
24/7 SOC with SIEM, EDR, NDR integration. AI-powered threat hunting, correlation rules, automated response playbooks. MTTD < 15 min, MTTR < 1 hour.
What's your security operations model (SOC)?
Hybrid SOC with US-based Tier 3 analysts, 24/7/365 coverage. Direct Slack/Teams integration for real-time collaboration. No offshore-only black box.
How do you ensure compliance across frameworks?
Continuous compliance monitoring with automated controls. Expert guidance through SOC 2, ISO 27001, HIPAA, PCI-DSS, FedRAMP audits. 100% pass rate.
What visibility will I have into security posture?
Executive dashboards with risk metrics, compliance status, vulnerability trends. Board-ready reports with business impact context, not just technical findings.
How do you handle incident response and forensics?
Documented IR playbooks, war room protocols, forensic investigation capabilities. Post-incident analysis with actionable recommendations and lessons learned.
What's the approach to vulnerability management?
Risk-based prioritization, not just CVSS scores. Automated scanning, coordinated patching, compensating controls. Critical/High remediation SLA: 24-72 hours.

Red Flags When Evaluating Providers
Warning signs that should make you think twice before signing a contract
No Clear Incident Response Process
Can't explain their IR playbooks, escalation paths, or war room procedures. No documented runbooks.
What to look for instead: Request sample IR playbooks, test escalation response time during sales process, review post-incident report examples.
Can't Explain Detection Capabilities
Vague answers about SIEM rules, threat hunting methodology, or detection coverage. No visibility into alert logic.
What to look for instead: Ask for sample detection use cases, false positive rates, threat intelligence sources, and coverage across MITRE ATT&CK framework.
No Compliance Expertise
Never completed SOC 2, ISO 27001, or your required framework. No in-house compliance experts.
What to look for instead: Validate past audit success rate, request compliance team credentials, check for framework certifications (CISA, CISSP, CISM).
No Security Certifications
Provider itself has no SOC 2 Type II, ISO 27001, or security certifications. Unaudited security practices.
What to look for instead: Request their SOC 2 Type II report, ISO 27001 certificate, and insurance coverage (E&O, cyber liability $5M+).
Offshore-Only SOC with Language Barriers
All analysts based offshore with limited English proficiency. Communication only via tickets, no real-time collaboration.
What to look for instead: Ask about SOC team locations, languages spoken, communication channels. Test real-time response during evaluation.
No Transparency into Security Tools
Won't disclose SIEM, EDR, or security tools used. Proprietary black-box systems with no integration options.
What to look for instead: Demand full transparency on security stack, integration capabilities, and access to underlying tools (Splunk, CrowdStrike, etc.).
Slow Response Times
SLAs measured in hours or days for critical incidents. No 24/7 coverage or on-call SOC analysts.
What to look for instead: Review SLA commitments: MTTD < 15 min, MTTR < 1 hour. Validate 24/7/365 coverage with no gaps.
No Vulnerability Management SLA
No commitment to remediation timelines. Scanning without coordinated patching or compensating controls.
What to look for instead: Request vulnerability remediation SLA by severity (Critical: 24h, High: 72h, Medium: 7d). Check patch coordination process.
