Happy Clients

Leading companies rely on us for their PKI and digital signature needs
``Our team was not able to handle the AATL needs for our Esign Service, so we researched and found Codegic. They provided a solution that worked in our workflow, and also put us in touch with an AATL certificate provider that was far less expensive than what we had been seeing. Their skills and expertise were obvious regarding AATL and PKI & literally, the project took less than 4 weeks. It was impressive. We would not hesitate to use them again.``
Aaron Jones Founder,
``Codegic team was immensely helpful in bringing our ideas for phone-based PKI authentication and signing to reality. Codegic was absolutely up to the challenge of bringing the security and accountability of our Authenticity Infrastructure's identity certificates to iOS and Android. They gave us secure solutions when it came to advanced digital signatures (CAdES, JSON signing) and WebCrypto. With top quality support, they are a go to shop for any serious PKI / Digital Signature development.``
Wes Kussmaul Reliable Identities, Inc.
``Security is at the heart of our business. We were struggling with our PKI implementation when Codegic came to the rescue. They not only sorted our technical issues but also designed the whole PKI for the infrastructure. There in depth PKI knowledge down to the code level helped us in many ways. I highly recommend their PKI technical expertise.``
