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?
Managed Security is quoted after scoping, and its detection tooling and response targets are set in the contract. On managed email, cloud and DevOps, a person responds to critical incidents within 1 hour, 24/7.
What's your security operations model (SOC)?
Monitoring is automated around the clock, and a person responds to critical incidents within 1 hour, 24/7. A dedicated security operations center is scoped and quoted separately through Managed Security.
How do you ensure compliance across frameworks?
Ongoing compliance support for SOC 2, ISO 27001, HIPAA or PCI-DSS, with a named control and evidence register, is Security & Compliance Support, from $1,500 a month. Larger programmes and audit support get a custom quote.
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.

Risk Reduction Metrics That Matter
Measurable security outcomes that demonstrate ROI to the board
Critical-incident response
24/7 on managed email, cloud and DevOps
Impact: A person starts triage while the incident is still small
Routine requests
Business hours, Monday to Friday
Impact: Day-to-day changes don't queue behind incidents
Vulnerability Remediation SLA
By severity (Critical/High/Medium)
Impact: Close attack windows rapidly
Assessment Turnaround
Initial report within 48 hours
Impact: Fast path to prioritized remediation
Breach Cost Avoided
IBM Cost of a Data Breach 2026
Impact: ROI of proactive security investment
False Positive Rate
PlatOps tuning target
Impact: Analyst efficiency and alert fatigue reduction
Average breach cost avoided per year: $4.99M(IBM Cost of a Data Breach Report 2026)

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 the response commitments in writing: what counts as critical, when the clock starts, and whether a person is on call 24/7/365 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.
