Deliverables (Artifacts)
Security Scorecard
Leadership‑ready snapshot of risks, trends, and actions
Control Matrix
Who owns what, mapped to CIS controls and your policies
Runbooks & Policies

Compliance Mapping
We align practical controls to common requirements and insurer questionnaires. Mappings available for:
Incident Response (IR) – Retainer or On‑Demand
When it happens
- Containment & isolation, evidence preservation
- Forensic‑light review & blast radius assessment
- Executive/insurer communications support
After it’s contained
- Root cause, corrective actions, policy updates
- User re‑education and phishing refreshers
- After‑action report with lessons learned
Optional: prioritized “first 72 hours” response plan and call tree.
Service Levels (SLAs)
| Priority | Assess | Harden | Monitor & Respond |
|---|---|---|---|
| P1 Security Incident | — | — | Response: 30 min Target containment: 6 hrs |
| P2 Vulnerability / Degraded | Risk review within 1 biz day | Patch/mitigate within 1–2 biz days | Response: 2 hrs Mitigation within 1 biz day |
| P3 Policy / User Issue | Next business day | Within same business day | Within 4 business hours |
SLAs and scope are tailored to your hours of coverage, locations, and toolset.
