About Us

Engineers first.
Security always.

DoThinkSecure is the security practice of the DoThink team — built on years of running data platforms in production.

OUR STORY

From data platforms
to AI defense.

For years our team has designed, migrated and operated PostgreSQL platforms, built CDC pipelines and delivered staging environments where changes could be rehearsed before they touched production. That is the DoThinkData practice, and it continues at dothinkdata.com.

Then clients started adding intelligence: copilots over the warehouse, RAG search over the knowledge base, agents operating the very pipelines we built. We began testing those systems the way we test data platforms — and kept finding the same wounds: prompts assembled from untrusted content, agents with standing database credentials, corpora that mixed access levels, outputs piped straight into SQL.

So we opened DoThinkSecure: the same engineering discipline, pointed at the new attack surface.

We secure AI the way we secure data: with architecture, least privilege and testing — not with stickers.

LLM security is the focus. Data security is the foundation. One team, one system.
PRINCIPLES

How we work.

Engineering, not fear

Every finding arrives with a fix, an effort estimate and a priority. No fear decks, no theater.

Least privilege, always

For humans, services, agents and models. Nothing holds more power than its job requires.

Measure

A control that is not tested is a hope. We re-test everything we ship and show you the numbers.

Plain language

Security that leadership and engineers can both read, understand and act on.
