Vulnerability Management and Technical Mitigation: Oversee the vulnerability Management program, penetration testing, and security assessments to identify vulnerabilities and remind technical remediation strategies.

Lead and manage internal and external audits, actively assisting in obtaining and maintaining relevant certifications.

Vendor and Third-Party Security: Assess, manage, and conduct due diligence on information security and data protection risks associated with third-party vendors. Review and negotiate Data Processing Agreements (DPAs) and security clauses, leveraging DPIAs to assess personal data processing posture and provide stakeholder recommendations.

Awareness and Training: Develop and deliver ongoing information security and data protection awareness training, including regular phishing simulations, to foster a security-conscious culture.

Stakeholder Engagement: Collaborate across departments (Legal, Service Delivery, HR) to embed security principles, translate technical risks into business-friendly advice, and liaise with regulatory bodies (e.g., ICO, DPA equivalents in EU) as required.

Proven experience (typically 3+ years) in information security, specialising in Cyber Security Governance, Risk, and Compliance (GRC) for managing risks, controls, and compliance activities.

Experience with leading vulnerability scanning tools (e.g., Nessus, Qualys, Tenable.io, Rapid7 InsightVM) and interpreting scan results to drive remediation.

Proven ability to coordinate and manage penetration testing engagements (web, network, mobile, cloud) and security assessments.

Strong technical understanding of common vulnerabilities (e.g., OWASP Top 10, CVEs) and attack vectors.

Understanding enterprise network security technologies: Firewalls (Palo Alto, Cisco ASA, Fortinet), IDS/IPS, VPNs, proxies, DLP, CASB and network segmentation architectures
