Vulnerability Management Security Sr. Analyst

What success looks like in this role: Vulnerability Assessment & Scanning

• Plan, schedule, and execute vulnerability scans across network, endpoint, server, and cloud environments using tools such as Nessus, Qualys, Rapid7 InsightVM, or Microsoft Defender Vulnerability Management.
• Perform authenticated and unauthenticated scans, ensuring coverage across all in-scope assets.
• Conduct ad hoc scans following remediation activities to validate closure of identified vulnerabilities.
• Maintain and continuously improve scan coverage, ensuring no asset gaps in the vulnerability programme. Analysis & Risk Prioritisation
• Analyse scan results and assess vulnerabilities based on CVSS scores, exploit availability, asset criticality, and business impact.
• Correlate vulnerability findings with threat intelligence feeds to identify actively exploited vulnerabilities that require expedited remediation.
• Differentiate and prioritise Critical, High, Medium, and Low severity vulnerabilities in line with client SLAs and organisational risk appetite.
• Provide contextual risk analysis beyond automated scoring, considering the environment and compensating controls in place. Remediation Management & Follow-up
• Assign remediation tasks to relevant resolver teams and track progress through to closure.
• Conduct regular follow-up with resolver teams to ensure patch deployment, configuration changes, or compensating controls are applied within agreed timelines.
• Escalate overdue or high-risk items to management and client stakeholders as appropriate.
• Validate remediation completeness through rescan confirmation and update records accordingly. Reporting & Governance
• Prepare and deliver monthly, weekly, and ad hoc vulnerability management reports for client and internal stakeholders, including trend analysis, SLA performance, and risk posture summaries.
• Maintain accurate and up-to-date vulnerability records across ticketing and vulnerability management platforms.
• Support governance meetings, monthly business reviews, and audit activities with relevant vulnerability data and evidence.
• Track and report on KPIs such as mean time to remediate (MTTR), vulnerability age, and scan coverage. Client & Stakeholder Engagement
• Act as a point of contact for client queries related to vulnerability findings, remediation status, and risk assessment.
• Provide guidance and recommendations to resolver teams and clients on remediation approaches, patch management, and risk acceptance.
• Participate in client calls and governance forums, presenting vulnerability posture and remediation progress clearly and concisely. Process Improvement & Documentation
• Maintain and continuously improve vulnerability management SOPs, playbooks, and process documentation.
• Identify opportunities to automate or streamline scanning, reporting, and remediation tracking workflows.
• Stay current with emerging vulnerabilities, CVEs, threat actor activity, and vendor advisories, and communicate relevant intelligence to the team and stakeholders.
• Support tool evaluations, onboarding of new scan targets, and integration of new clients or entities into the vulnerability programme. You will be successful in this role if you have:
• 4–6 years of experience in cybersecurity with at least 2–3 years focused on vulnerability management.
• Hands-on experience with vulnerability scanning tools — Nessus Professional, Qualys, Rapid7 InsightVM, Defender or equivalent.
• Working knowledge of network protocols, operating systems (Windows, Linux), and cloud platforms (Azure, AWS, GCP).
• Experience with ITSM and ticketing platforms such as ServiceNow for remediation tracking.
• Strong analytical and report-writing skills with the ability to communicate technical findings to non-technical audiences.
• Experience working in a managed security services or client-facing environment is preferred.
