Roan Caws — CEO

I’m a UK-based security consultant and AI practitioner with hands-on experience across offensive security, remediation, and secure architecture. I hold Pro Hacker rank on HackTheBox and have completed most of the HTB Academy curriculum. My work spans penetration testing, threat modeling, and practical AI integration for teams that need results they can safely ship. I have consulted for large private and public sector organisations, as well as startups, helping them harden infrastructure, test applications, and adopt AI safely. On the AI side I work with AI service providers and open source models, host and fine-tune models from Hugging Face, and build agentic workflows using tools such as Microsoft AutoGen. What I do: - Penetration testing for networks, cloud, web, and local applications - Security reviews, threat modeling, and remediation guidance - AI security and governance for applied ML and LLM systems - Practical enablement for teams using VLMs and LLMs in production How I work: - Evidence-driven, reproducible findings with clear remediation steps - Straightforward communication with engineers and stakeholders - Remote delivery, UK business hours with flexibility for US teams Ethics and scope: I only accept engagements where the client can prove ownership or explicit testing authorisation. Before work starts, we agree a written scope that lists in-scope assets, constraints, and escalation paths. This protects both sides and keeps the work focused. Native English speaker, UK based, available for short sprints or ongoing advisory. If you need a practical partner to find vulnerabilities, reduce risk, and make smart choices about AI, I’m ready to help.
