We’ve been recertified! CodeTwo remains Microsoft 365 Certified app since 2022

We’re excited to share that CodeTwo Email Signatures 365 has been once again recertified under the Microsoft 365 App Compliance Program. It is also the first and only email signature solution fully certified by Microsoft, and we continue to renew this certification every year.

This ongoing certification gives our customers extra assurance that our cloud service for managing email signatures, legal disclaimers, and branding in Microsoft 365 – together with its Microsoft Azure infrastructure and Outlook add-in – continues to meet Microsoft’s highest standards for security, compliance, and data protection, making it the most secure email signature solution on the market.

CodeTwo has consistently achieved M365 Certification since 2022, demonstrating their commitment to handling their customers’ data with care and security. We appreciate their diligence and look forward to the continued partnership with CodeTwo and the M365 App Compliance Program.

Why being Microsoft 365 Certified matters?

Microsoft 365 Certification is not a one-time check but an ongoing validation process. Each year, certified apps are reviewed and audited against well-established industry standards (such as ISO 27001, SOC 2, and PCI DSS), and undergo penetration testing conducted by Microsoft’s security experts. All submitted audit evidence must be up to date to confirm that certified solutions remain secure and compliant. Learn more about Microsoft 365 Certification framework

The certification confirms that we uphold the highest levels of security and data protection, safeguard user privacy with absolute rigor, and consistently meet (and often exceed) the most demanding standards Microsoft requires from its trusted partners.
