Upholding excellence in compliance
Proton supports our customers' compliance requirements by establishing clear contracts, conducting comprehensive security audits, and adhering to up-to-date international standards like ISO 27001.

This is the gold standard for information security management systems (ISMS). This certification reflects our commitment to maintaining the highest level of security across our internal processes. ISO 27001 ensures that we systematically assess and address risks, implement comprehensive security controls, and continuously improve our security practices.
Third-party validation
While frameworks like DORA, NIS2, and CCPA emphasize using providers with state-of-the-art security, our independent audits and ongoing efforts to obtain additional certifications ensure that we meet and exceed these expectations.
