Isaiah Dasen
AppSec Engineer & Developer
I help enterprises solve their hardest security problems — application security, bot mitigation, API protection, DDoS, and identity. 15+ years spanning network infrastructure, identity, and AppSec — with a side passion for vintage Pokémon cards.
About Me
I'm a cybersecurity leader with 15+ years of experience architecting solutions and leading teams across the full security stack — networking, network security, SaaS security, and zero trust. I build relationships, identify value, and translate complex technical concepts into actionable deliverables.
My background spans the full application security stack: network-level work at F5, identity protocols at Okta, bot mitigation and API security at DataDome, and my current role at Thales managing technical pre-sales for the Imperva AppSec portfolio — WAF, Bot Management, API Security, and DDoS — alongside CipherTrust and Luna HSM.
Outside of security, I collect vintage Pokémon cards — which is why this site doubles as a small card shop. This deployment runs on Google Cloud Platform and serves as a live security demo environment.
