Job Description

We are seeking a hands-on cybersecurity professional with specialised experience across Security Exposure Management (SEM), External Attack Surface Management (EASM), Third-Party Cyber Risk/Assurance and Cyber Threat Intelligence (CTI).

The role will focus on continuously identifying external cyber exposures, assessing third-party security posture, validating material cyber threats and driving remediation across complex enterprise environments.

Key Responsibilities

• Perform continuous external attack-surface discovery and monitoring of internet-facing assets, domains, subdomains, IP addresses, certificates, exposed services and cloud resources.
• Identify unknown, unmanaged and externally exposed assets and validate material security exposures.
• Analyse vulnerabilities and external exposures against exploitability and threat intelligence to determine actual organisational risk.
• Conduct end-to-end cybersecurity assessments of third-party service providers, including inherent risk assessment, security questionnaires, evidence review, control validation, risk rating and residual-risk assessment.
• Perform cybersecurity due diligence and continuous assurance of critical third parties.
• Assess fourth-party/nth-party dependencies and cyber-risk propagation across the supply chain.
• Conduct structured third-party assessments using SIG, CAIQ, VDD/ODD or equivalent methodologies.
• Assess security controls against NIST CSF, ISO 27001 and CIS Controls.
• Investigate emerging vulnerabilities, active exploitation, external threats, leaked credentials, impersonation and digital-risk indicators.
• Correlate threat intelligence, vulnerability information, asset criticality and external exposure to prioritise remediation.
• Validate clear-and-present-danger cyber threats affecting the organisation or critical third parties.
• Develop cyber exposure, third-party posture, risk dashboards and management reporting.
• Automate security monitoring, enrichment, assessment and reporting activities using Python, PowerShell and/or Bash.
• Work with security engineering, infrastructure, cloud, risk and business stakeholders to drive identified risks through remediation and closure.

Essential Requirements

• 3–5 years of hands-on cybersecurity experience with direct exposure to Security Exposure Management, EASM, Attack Surface Management or Digital Risk.
• Hands-on experience conducting third-party/vendor cybersecurity assessments, beyond vendor coordination or procurement activities.
• Experience conducting security questionnaires, evidence/control reviews, risk assessments and remediation tracking.
• Practical understanding of third-party, fourth-party and nth-party cyber risk.
• Experience with external attack-surface, cyber exposure, digital-risk or threat-intelligence platforms.
• Strong vulnerability-management and risk-based prioritisation experience, including CVE, CVSS and actively exploited vulnerabilities.
• Practical knowledge of NIST CSF, ISO 27001 and CIS Controls.
• Strong understanding of TCP/IP, DNS, HTTP/HTTPS, TLS, APIs and internet-facing infrastructure.
• Security exposure across AWS, Microsoft Azure and/or Google Cloud Platform.
• Hands-on scripting/automation experience using Python, PowerShell and/or Bash.
• Strong analytical, documentation, stakeholder-management and security-risk communication skills.

Relevant Technology Exposure

Hands-on experience with one or more of the following or equivalent technologies is highly desirable:

SecurityScorecard, BitSight, RiskRecon, CyCognito, Censys, Microsoft Defender EASM, Tenable Attack Surface Management, Palo Alto Cortex Xpanse, Recorded Future, Flashpoint, Mandiant Threat Intelligence, ZeroFox, watchTowr, ServiceNow GRC/IRM and RSA Archer.

Preferred Certifications

• CompTIA Security+ / CySA+
• CEH
• GIAC GSEC / GCIH
• CISSP / Associate of ISC2
• CISM
• ISO 27001 related certifications

Candidates should have demonstrable hands-on experience in external cyber exposure and/or third-party cybersecurity assessment. Experience limited primarily to SOC alert monitoring, SIEM operations, general IT audit, vulnerability scanning or vendor coordination without direct cyber-risk assessment experience may not meet the specialised requirements of this position.
