You usually find me at one of these moments: an enterprise customer sent a security questionnaire you can't fully answer, investor due diligence flagged your security, a SOC 2 or HIPAA requirement is blocking a deal, or you shipped fast with AI tools and you're no longer sure what's exposed. If any of those is you, you're in the right place. ๐‘พ๐’‰๐’‚๐’• ๐‘ฐ ๐’…๐’: โœ… Application & API penetration testing: web apps, APIs, auth/access control, OWASP Top 10, and the AI-generated-code failure patterns (hardcoded secrets, broken authz, injection) โœ… SaaS security & pre-launch hardening: find and fix what's exploitable before you scale, fundraise, or sign that enterprise customer โœ… Compliance & GRC: SOC 2 readiness, HIPAA/HITECH, security questionnaires, and controls mapped to frameworks like NIST and ISO 27001 so audits stop being a fire drill โœ… Fractional security ownership: threat modeling, API contracts, zero-trust architecture, penetration tests, logs analysis, and the security playbooks your team actually follows Across my engagements I've reduced measured security risk by ~80% on average, eliminated injection and access-control flaws, and secured 7+ startups with zero breaches since. Whether it's a regulator, an auditor, an investor, or an enterprise customer asking the hard questions, send me the scope and I'll tell you straight where you stand and what I'd fix first.

๐Ÿ”’ You need security that actually works โ€” not a report that says it does. The organisations I work with want to find the vulnerabilities that matter, fix them with confidence, and get on with growing their business without security becoming the thing that stops them. I have delivered over 1,000 commercial penetration tests across 27 years. Not side projects. Not internal assessments. Full mission-critical engagements for high street and investment banks, hedge funds, insurance firms, government departments, police, military, national infrastructure, retailers, law firms, airports and more. I led the security architecture for the Athens 2004 Olympics internet-facing systems. I was lead architect on the UK Cyber Essentials scheme at launch. I have published in commercial security press and guest lectured at universities. There is a difference between someone who does penetration testing and someone who has seen every flavour of environment, every attack pattern, and every way organisations deceive themselves about their security posture. That difference is what you are hiring. ๐ŸŽฏ Where can I help: ๐Ÿ—ก๏ธ Network & Infrastructure Penetration Testing โ€” adversarial testing of internal and external infrastructure, finding exploitable exposures before an attacker does. ๐ŸŒ Application Penetration Testing โ€” web application and API security testing against real attack patterns: authentication, authorisation, input handling and business logic flaws. โ˜๏ธ Microsoft 365 Security Assessment โ€” Entra ID, Conditional Access, PIM, Intune, DLP, sensitivity labelling, Exchange Online and Defender for Office 365. ๐Ÿ”ท Azure Security Assessment โ€” identity and access management, network controls, storage and key management, Defender for Cloud posture, and monitoring coverage. ๐ŸŸข Google Workspace, GCP & AWS Security Assessments โ€” configuration and access control assessments across Google and Amazon cloud environments. ๐Ÿ›๏ธ Security Architecture and Risk Advisory โ€” senior technical input on architecture decisions, control design and risk without a full engagement commitment. ๐Ÿ‘ค Every engagement is delivered directly by me โ€” David Morgan, founder of Metis Security. No account management layer, no junior handoffs, no templated output. You work with the person conducting the analysis and writing the report. ๐Ÿ“‹ How I work is as important as what I find Every finding in my reports is one I will defend as genuinely material to your environment. No padding, no low-hanging fruit included to justify the fee, no default risk ratings copied from a scanner. If your context changes the risk, the rating reflects that. What you receive: โœ… A visually structured report with clear separation between executive summary, findings and remediation roadmap โ€” written to be read by people who are not security specialists โœ… Risk ratings adjusted to your specific environment and context, not defaulted from a tool โœ… A prioritised remediation roadmap so your team knows exactly what to fix first and why it matters commercially โœ… Immediate escalation of any high-risk finding or schedule-affecting issue during the engagement โ€” you are never waiting until the end to hear something important โœ… Daily status updates so you always know where the engagement stands โœ… A debrief call at close to walk through findings, answer questions and finalise the report before it is delivered CISSP | ISSAP | Microsoft Security certifications | 27 years If you need to know whether your environment is genuinely secure โ€” not whether it looks configured โ€” I am worth a conversation.
