About Us

As organizations, your security maturity is directly related to the quality of your security testing program. As security service providers, your consultancy relies on personnel. In both instances; the human element is critical.

As an alternative to using junior resource as many consultancies do, Atlan Digital R&D only provides highly experienced consultants to deliver on engagements. These resources are specialists in the relevant domains.

We only field contractors that have a minimum of 5-10 years experience having delivered at the highest level of offensive security consulting.

Whether it is our contracting leads for a project based engagement, or cross disciplinary team of four contractors that you seek for a challenging multi-month end-to-end engagement, or an ongoing Penetration Testing as a Service (PTaaS) offering - we can deliver world class outcomes.

Background, experience, and selected research and tooling.

Tom has eleven years of operational offensive-security experience across red teaming, application and infrastructure security, custom implant and C2 development, and advisory, delivering regulator-led engagements for financial institutions and critical national infrastructure across Europe, the US and the Middle East. Since 2019 his focus has been the intersection of machine learning and offensive security: he is co-author of SharpML, architect of the TURUL product and SilentPath, and co-instructor of the Machine Learning for Red Teams training, delivered to enterprise and federal security teams. He founded Atlan Digital R&D in 2024 to build AI-driven offensive-security capability, and was shortlisted for NATO DIANA that year, after serving as Technical Manager in KPMG's Cyber Defence Services practice in 2021 and running its predecessor consultancy, Atlan Digital Limited, which worked with multiple European stock exchanges, heavy industry, blockchain and custody, and other areas. He is OSCP certified and has completed many other training programmes.
