• Design and develop advanced detection content (Sigma rules, UEBA baselines, custom rules) across SIEM and EDR platforms.
• Identify and close detection gaps through continuous telemetry analysis and logic refinement.
• Coordinate log source visibility reviews, baselining, and high-fidelity use case design.

5. MSSP Reporting & Executive Briefings

• Prepare and deliver Monthly and Quarterly Security Reports to MSSP clients covering:
• Alert trends, threat landscape updates, SLA/KPI dashboards
• Executive summaries, incident breakdowns, and risk remediation insights
• Present findings to customer stakeholders via scheduled service review meetings and executive briefings.
• Ensure SLA compliance targets are tracked and reported, including MTTD, MTTR, escalation compliance, and false positive rates.

6. IR Tabletop Exercise Management

• Plan, facilitate, and report on Quarterly Incident Response Tabletop Exercises with internal and external stakeholders.
• Develop realistic, role-based tabletop scenarios (ransomware, insider threat, data exfiltration, etc.).
• Deliver Tabletop Exercise Reports with participant feedback, lessons learned, and actionable improvements.

7. SOC Governance & Pre-Onboarding Support

• Contribute to MSSP onboarding by helping define:
• Log source mapping and ingestion validation
• Detection rule baselines, alert taxonomy, and escalation matrix
• Secure communication procedures and SLA/OLA handoff alignment
• Support pre-engagement risk assessments and operational readiness reviews.
