Critical Software builds software for sectors where failure is not an option: space, aviation, energy, defence, finance, e-commerce, medical devices, transportation. With more than 1,000 employees serving customers in industries that have zero tolerance for compromise, the company's own security posture had to mirror the standard it engineers into its products.

Why "once a year" couldn't be the answer

In zero-tolerance sectors, a single successful attack can cascade into life-safety or national-security consequences. Critical Software's customers needed assurance that the company's own assets were validated continuously, not just on the date the last pentest report was issued.

The team needed an approach that could:

• run 24/7 against new deployments
• prioritise findings by real exploitability
• deliver actionable guidance their engineers could act on without losing sprint velocity

Continuous, validated, and integrated

Ethiack deployed Hackian against Critical Software's external attack surface. Every code change triggers fresh testing. Every finding is prioritised, paired with mitigation guidance, and validated for exploitability through proof-of-exploit, keeping false positives below 1%. No more weeks of triage on phantom issues.

Within the first phase, Critical Software identified and mitigated four high-impact exploitable risks across 25 assets: exactly the validated, prioritised signal a high-stakes engineering organisation needs.

The change isn't operational, it's strategic. Critical Software can now reassure its high-risk-industry customers, every day, not once a year, that the assets they depend on are tested, validated, and continuously defended.
