Vulnerability Management and Compliance

Support vulnerability scanning and analysis, ensuring full visibility into security gaps.

Collaborate with IT teams to enforce patch compliance, particularly for critical and high-severity vulnerabilities.

Provide reports on vulnerability trends, security risks, and remediation progress.

Conduct firewall rule reviews, cloud security assessments, and network security testing.

Evaluate SIEM rules, endpoint security configurations, and cloud security controls for misconfigurations.

Support vulnerability management efforts, ensuring timely remediation of identified risks.

Assist in evaluating and testing new security tools, integrating them into SOC workflows.

MSSP Oversight and Performance Management:

Act as a primary escalation point for MSSP investigations, ensuring appropriate response times and quality.
