What our clients say about us

Leo C. - VP of Engineering, Geckoboard

As the VP of Engineering at Geckoboard, I had the pleasure of working closely with Leviathan Security Group. I was thoroughly impressed by their expertise, professionalism, and commitment.

Leviathan’s Security Engineers approached the project with a keen eye which revealed security gaps that had not been uncovered by any previous cybersecurity firms. Leviathan’s team is exceptionally skilled and “switched on.” When working to address security findings, they were responsive, thoughtful, and highly engaged with our project and the tight deadlines at play.

In summary, Leviathan is an outstanding security partner. Their dedication and technical expertise make them a true asset to any organization that prioritizes information security.

Understanding our customers' concerns isn’t solely a part of the job—it's the essence of it. To us, vulnerabilities aren’t simply items on a list; they're chapters in a story that our customers are living every day.

We listen, we learn, and we transform that understanding into reports that not only inform, but they resonate deeply.

They're actionable, they're clear, and they empower our clients to act with confidence.

It's the compelling stories we craft from complex data that keep our customers returning—because they know the quality of our narratives is the key to their security.
