Isaiah Dasen
The Application Security Guy
I help enterprises understand and solve their hardest security problems — bot mitigation, application security, data protection, and identity. Currently bringing deep technical expertise to the cybersecurity product space at Thales, with a side passion for vintage Pokémon cards.
About Me
I'm a cybersecurity sales engineer with a career built across network infrastructure, identity, application delivery, bot mitigation, and data protection. Over 15+ years I've worked hands-on with the products and platforms that secure modern enterprises — from F5 BIG-IP and Okta to DataDome and Thales HSMs.
At DataDome I led the solutions and services team focused on stopping bots, account takeover, and API abuse at scale. At Okta I specialized in identity federation and authentication protocols. At F5 — where I spent the better part of a decade across two stints — I grew from network support into enterprise account engineering and eventually security-focused solutions engineering.
Today at Thales I help organizations solve their toughest data protection and key management challenges using hardware security modules and encryption platforms. And when I'm not in front of a whiteboard or a demo environment, I collect vintage Pokémon cards — which is why this site doubles as a small card shop.
