OffSeq — short for Offensive Sequence — was founded in 2022 on a simple belief: you cannot defend what you have never seen attacked. Every engagement begins from the attacker’s perspective, because that is where real risk lives.

We pair deep offensive expertise with the regulatory reality European organizations face. NIS2, GDPR and Latvia’s national requirements aren’t an afterthought in our work — they shape how we test, report and advise.

In 2026 OffSeq became an accredited PECB training partner, extending our work into internationally recognized ISO and cybersecurity certification — part of a mission to make internationally certified security skills accessible across Latvia and the EU.

How we think

Principles we operate by

Adversary-first

We start from how you’d actually be attacked, not a generic checklist.

Plain-spoken

Clear findings and honest advice. No fear-selling, no jargon for its own sake.

Evidence over opinion

Every claim is backed by proof, severity and business impact.

Built for Europe

Compliance and context for the regulations our clients live under.
