SSL inspection Certificate mystery

is it possible to use a verisign (or any other CA) for SSL inspection(web filtering, appcontrol) , in order to get rid of annoying certificate warning on https sites when using the inbuilt fortigate CA ssl proxy certificate.

If yes what type of certificate needs to be bought , a single ssl certificate etc....

from this discussion ,  i am doubtful about the possibility. 

 

Apart from this i see no other way , by which the https certificate warning can be avoided completely. as smartphone, tabs , ipads are never part of domain so its not possible to use active directory infra to push local certificate and its a tedious task to install fortigate ssl proxy cert manually on every single device.

If a public CA started handing out signing certificates that people could use for SSL inspection the first thing I would do is remove their root from my browser store. Certificates are about trust... how can I trust a CA that lets others do SSL inspection on any site?

The short answer is no, this is what SSL is suppose to do, give you  or let me re-phrase " the end-user the warning " & then he/she can make the validation to proceed after being warned.

You can use a custom certificate for SSL inspection, instead of the default FortiGate cert. You can find instructions for how to do this here: http://cookbook.fortinet.com/preventing-certificate-warnings/#custom

Technical Writer, FortiOS

Let me know if there's anything you want to see added to the FortiGate Cookbook.

Hi,

 

Which version of the fortiOS are you using. After thinkering a little bit and a couple of forums found a solution for 5.2.1 and 5.2.2. I only the certificate issue on sites that are actually being barred from use.

 

Is that what you are looking for?

Exactly, it's called a chain of trust for a reason
