Key Benefits

  • Robust authenticity

    – Ascertia’s ADSS CA/PKI Server offers a robust certification authority service, which enables operators to build as many Trusted Certification Authorities as they need to satisfy business requirements for trust infrastructure.

  • Enhanced security

    –Keys and certificates are issued from a central Certificate Authority (CA). Each key is unique and ADSS CA/PKI Server enables easy rotation of keys and certificates on a regular basis. Whilst the initial deployment can be more complex, it provides strong proof of identity and full credential lifecycle management.

  • Comprehensive digital trust

    – ADSS CA/PKI Server is core to providing digital trust and is used by global TSPs, businesses and governments. It delivers a highly secure and scalable platform upon which services can be built to issue digital certificates to people, devices and applications.

Our experience with the ADSS Server product and its availability and performance is what I, as an IT Professional and as Nikken’s IT manager of 9 years believes makes Ascertia the standards by which all companies in this industry sector should consider following.
