Use this address to verify a message from me, continue an existing disclosure, or discuss scoped security work.
Published details
Limited public footprint
My online presence is deliberately limited because this work often involves sensitive reports, private vendor conversations, and evidence that should remain confidential.
I do not publish private company names, screenshots, or report references without permission. If you need to verify a message, start a new email using the address published on this page.
For commissioned work
If you want to discuss scoped testing, send a short email with the essentials below. Please do not include credentials, tokens, customer data, or sensitive evidence in the first message.
- The product or feature area you want reviewed
- The security boundary or concern you want tested
- Whether this is one-off, quarterly, or fix validation work
- The preferred timeframe and main technical contact
- Who can approve the testing scope and authorisation
Please do not send passwords, access tokens, private keys, or large amounts of third-party data by ordinary email. Where sensitive evidence is required, I can agree an appropriate secure transfer route.
