WORK HISTORY
Security Engineer @Sage
Security Engineer specialising in Cyber Threat Intelligence (CTI) and adversary analysis, with 20+ years’ experience in regulated financial services. Currently a Security Engineer at Sage UK, leading threat-led risk prioritisation and operational intelligence integration.Expert in adversary TTP analysis using MITRE Corporation ATT & CK, Diamond Model and Cyber Kill Chain to identify control gaps across endpoint, network and cloud environments. Track global ransomware, supply-chain and zero-day activity, producing actionable intelligence briefings for SOC and executive stakeholders.Correlate CVE disclosures with Cybersecurity and Infrastructure Security Agency KEV and FIRST EPSS to prioritise exploitable vulnerabilities based on real-world threat activity. Designed structured workflows in ArmorCode to reduce false positives and align remediation with adversary behaviour.Collaborate closely with SOC teams, mapping incidents to ATT & CK techniques, enriching alerts with threat context, and maintaining curated IoC libraries. Conduct malware triage and dark web monitoring to identify pre-compromise signals.Hands-on exposure to intelligence platforms such as Recorded Future, ThreatConnect and MISP, alongside operational tooling including CrowdStrike, Splunk and Qualys.Strong technical foundation across cloud security (AWS/Azure), DevSecOps, endpoint defence and enterprise infrastructure, enabling intelligence to translate directly into measurable defensive improvement.

ABOUT MANOJ SATHEESAN
IT Security Consultant specialising in Cyber Threat Intelligence (CTI), with over 20 years of experience across enterprise IT and regulated financial services environments including banking, insurance and retail. I combine intelligence-led analysis with hands-on security engineering to strengthen detection, response and risk-based decision-making.My core focus is threat intelligence production and operationalisation, including:Threat actor and campaign analysisMITRE ATT & CK technique mapping and adversary modellingIOC analysis, enrichment and contextual correlationOSINT collection and intelligence validationVulnerability intelligence using CVE, CVSS, EPSS and CISA KEV prioritisationThreat-informed defence aligned to NIST and industry best practice frameworksI specialise in translating raw intelligence into actionable outcomes by integrating CTI into SOC operations, SIEM use cases, detection engineering, vulnerability triage and SOAR playbooks. My approach ensures intelligence directly improves defensive coverage, reduces noise and supports measurable risk reduction.Beyond CTI, I bring broad technical capability across:Vulnerability management and contextual triage across SAST, DAST, SCA and container security platformsDevSecOps integration (CodeQL, Semgrep, Fortify, Checkmarx, GitHub Advanced Security and AI-assisted remediation tooling)Endpoint protection, malware analysis and intrusion detection/prevention systemsCloud security architecture across AWS, Azure and IBM CloudCDN and edge security (Cloudflare, AWS CloudFront)Network and micro-segmentation security (Cisco firewalls, routers, switches, VMware NSX-V/NSX-T)Enterprise middleware security including IBM WebSphere DataPower, MQ, Application Server, Integration Bus, App Connect Enterprise and WebSphere CommerceI have supported cloud migrations, security architecture reviews and control gap assessments within highly regulated environments, ensuring alignment to compliance and governance expectations.Currently completing the final module of a GCHQ-accredited MSc in Cyber Security from Edinburgh Napier University, with advanced focus areas in cryptography, malware analysis and digital forensics.I operate confidently across intelligence, engineering and architectural domains, engaging senior stakeholders while remaining technically hands-on. My strength lies in connecting threat intelligence, vulnerability context and defensive engineering into a cohesive, intelligence-led security strategy.
