Revive Adserver is a software package that anyone can download and then host on their own server(s). As such, certifying organisations like the IAB, or companies like Google with the 3rd party ad server certification program, are unable to certify the software itself. After all, even if the software is very good (and we believe it is), it is possible to implement it very badly and still end up with an unreliable ad server application.
Individual implementations of Revive Adserver can be certified, and there are many known cases where this has been successful. For example, Platform IQ, the company owned by Revive Adserver team member Erik Geurts, hosts a video ad server implementation based on Revive Adserver and the commercially available VAST2 plugin VidiX. This implementation has been certified by Google for their “VAST InStream” requirements, allowing the pre-roll video advertisements to be displayed on YouTube. Google calls this a 3PAS (third party ad server) certification.
