Comodo Dragon ver 17.2 beta (with CertSentry preview) is now available

Comodo Dragon Beta 17.2 is now available for beta testing and should not be used on production systems.
The beta can be downloaded from the following link:


  • Chromium core 17.0.963.46.



  • “Comodo Dragon is unresponsive” message when launching a second instance of Dragon after install.
  • Update was not downloaded when current tab had a low-validation SSL certificate warning loaded.

This beta release has a technology that will enable us to test a new technology that will help us fight against “State sponsored attacks”.

So your help in testing is much much appreciated!

thank you


Can you give a little more detail about ‘Certsentry’?

its about measuring the capability of the OCSP infrastructure, so that we can build new technologies to address them.

That sounds like a total different approach then Google seems to take by dropping ‘soft-fail’ in Chromium…


we want “revocation to work”!;msg583811#msg583811

here is a more comprehensive answer about CertSentry.

This version fixes the Extension related crashes that I was having when running in portable mode :slight_smile:

Thanks !!!

Same for me but then in install mode.

To whom can I contribute German translations for the added Comodo features?
