OffSeq — short for Offensive Sequence — was founded in 2022 on a simple principle: you cannot reliably defend a system that has never been tested from an attacker’s perspective. Every engagement begins by identifying the paths an adversary could actually use.
We combine deep offensive-security expertise with the regulatory requirements European organisations face. NIS2, DORA and GDPR shape how we test, report and advise.
In 2026, OffSeq became a PECB training partner, expanding our work into internationally recognised ISO and cybersecurity training and certification across Latvia and the EU.

Principles we operate by
- 01
Attacker-led
We start with the attack paths most relevant to your environment, not a generic checklist.
- 02
Clear communication
Clear findings and candid advice, without fear-based selling or unnecessary jargon.
- 03
Evidence over opinion
Every conclusion is supported by evidence, a severity rating and an assessment of business impact.
- 04
Built for Europe
Our work reflects the regulatory and operational context of European organisations.
