Nikolina Palasrinne
Founder & Principal, Rubix Legal
When CertMate was looking for the right cyber security support to help grow in the SaaS market, we found far more than a vendor. We found a genuine partner. What stood out wasn’t just their expertise, but how readily Chris and the team adapted to the way we work. Every question was met with a fast, practical answer. As a SaaS business, having a cyber security partner that understands our space and grows alongside us has made all the difference.
