Organizations don't fail because they lack technology. They fail because security weaknesses remain undiscovered until attackers exploit them.

I find the weak spots in web apps, APIs, and networks before a real attacker does, then show your team exactly how to close them. I've worked both sides of security. I test systems the way an intruder would, and as a SOC analyst I've watched how those same attacks show up in the logs. That mix means I don't just hand you a list of problems. I can tell you what an actual breach would look like on your side and how to spot the next one early. Most "penetration test" reports are a scanner's output dumped into a PDF and padded with false positives. I don't work that way. Every finding is tested by hand, proven with a working proof of concept, and rated by the real risk to your business, so your developers fix what counts instead of chasing noise. What I do: Web application penetration testing, full OWASP Top 10 coverage API security testing for REST and GraphQL Internal and external network and infrastructure VAPT Cloud and SaaS security assessments SOC support: SIEM monitoring, log analysis, threat detection, and incident response Reviewing existing scan results and stripping out the false positives Things I regularly find: SQL injection, SSTI, command injection, XSS, CSRF, IDOR and broken access control, authentication and session flaws, business logic abuse, API weaknesses, and server and cloud misconfigurations. Every report gives you a severity rating, the business impact in plain English, steps to reproduce the issue, and remediation your developers can ship right away. All work is fully authorized, kept inside the agreed scope, and confidential. Send me your scope or tell me what's keeping you up at night, and I'll walk you through how I'd test it and what you'll get back.

🔒 You need security that actually works — 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. 🎯 Where can I help: 🗡️ Network & Infrastructure Penetration Testing — adversarial testing of internal and external infrastructure, finding exploitable exposures before an attacker does. 🌐 Application Penetration Testing — web application and API security testing against real attack patterns: authentication, authorisation, input handling and business logic flaws. ☁️ Microsoft 365 Security Assessment — Entra ID, Conditional Access, PIM, Intune, DLP, sensitivity labelling, Exchange Online and Defender for Office 365. 🔷 Azure Security Assessment — identity and access management, network controls, storage and key management, Defender for Cloud posture, and monitoring coverage. 🟢 Google Workspace, GCP & AWS Security Assessments — configuration and access control assessments across Google and Amazon cloud environments. 🏛️ Security Architecture and Risk Advisory — senior technical input on architecture decisions, control design and risk without a full engagement commitment. 👤 Every engagement is delivered directly by me — 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. 📋 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: ✅ A visually structured report with clear separation between executive summary, findings and remediation roadmap — written to be read by people who are not security specialists ✅ Risk ratings adjusted to your specific environment and context, not defaulted from a tool ✅ A prioritised remediation roadmap so your team knows exactly what to fix first and why it matters commercially ✅ Immediate escalation of any high-risk finding or schedule-affecting issue during the engagement — you are never waiting until the end to hear something important ✅ Daily status updates so you always know where the engagement stands ✅ 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 — not whether it looks configured — I am worth a conversation.
