Do you hold any independently assessed certifications? For example ISO 9000/14000/20000/22300/27000, SOC 2, NIST, FedRAMP, TISAX?

Altium follows industry best practices for cyber security and keeps customer data protection as a fundamental commitment.
We have SOC2 Type 1 certification, and are in the process of obtaining Type 2 (the SOC2 Type 1 report can be be shared upon request, with a mutual NDA in place).
We conduct annual penetration testing by specialized third-party cyber security providers (see “Do you do regular penetration testing by a third-party company? Can you share a results report?), have rigorous security protocols (“Does Altium maintain an SDLC?) and have a full set of organizational security controls.

At present, Altium 365 does not have official government certifications and is not ITAR compliant.
