What I'm looking for

I'm looking to build threat intelligence, detection, and response capabilities where I can combine OpenCTI, OSINT, vulnerability remediation, and AI-assisted analyst workflows to strengthen security operations.

At Brookcourt Solutions, I build and operate OpenCTI end-to-end, integrate multi-source threat feeds, and produce threat intelligence reporting for technical and executive stakeholders. I also use Tenable, Recorded Future, OSINT, NetScout, and AI-augmented workflows with Ollama and Open WebUI to support detection, triage, remediation, and supplier-risk decisions.

Previously at Softcat, I protected more than 3,000 users through phishing triage, IAM, endpoint controls, vulnerability remediation, and Cyber Essentials Plus work. I reduced VIP impersonation phishing attacks by 90% through targeted Mimecast sender-blocking policies and supported Red Team remediation.

Alongside cybersecurity, I design secure UniFi networks, VLAN segmentation, firewalls, VPNs, CCTV monitoring, and Home Assistant automations for SME clients.
