Recommended Posts

Posted (edited)

Hello,

I had block some websites with policies successfully. 

My query is if it is possible  when I open a website which is in the block list then to redirect in specific webpage instead of error on browser "ERR_NAME_NOT_RESOLVED"

 

To avoid

What version of Endpoint do you have installed? Do you have SSL filtering enabled? What browser and version do you use?

What website did you attempt to block and how did you block it in a policy? Did you block it via Web Control or Web access protection -> URL address management ?

In order to block facebook, do the following:

- add *facebook.com* in the list of blocked addresses
- make sure that SSL filtering is enabled
- make sure that communication with trusted domains is not excluded (by default it is)
- in order for filtering to work in Chrome, QUIC protocol needs to be disabled as per https://support.eset.com/kb6757/

Please provide me with logs collected with ESET Log Collector on the troublesome machine.

To get rid of this error, you must have SSL filtering enabled. Then you should get the yellow notice that I posted above. The error is displayed by Chrome so we cannot do anything about it until protocol filtering is enabled in Endpoint. Please provide me with logs collected with ELC from the client so that I can check if everything is set up correctly in Endpoint.

One more thing, if you want to use a custom message with graphics, you will have to block access via Web Control and not via URL management:

In Web Control wildcards are not supported so just create a URL-based blocking rule for facebook.com.

I return because i have 2 question more about that.

First is why cannot view policy on Client ESET? (missing Web Control under WEB AND EMAIL)

eset_app.jpg.0e5685c713fa77b8ece5260b2a239c57.jpg

but on ERA is ok

eset_web_control.thumb.jpg.56b42f3201fdfde50b362bd60d6a1acc.jpg

 

Second is not only not appear on client but not applied also.

It appears that you have ESET Endpoint Antivirus. Web Control is included only in ESET Endpoint Security.

For blocking websites you can use URL address management, however, without the option to choose a custom note and graphics.

Yes is ESET Endpoint Antivirus.

In ESET Endpoint Security can i have only note or graphics or i have the ability to redirect it on my URL (that include custom access denied webpage)?

Only an image can be linked through a url. I think the main reason for this is to prevent situations when the url would be inaccessible and users would not get any information then. If the url to the image is inaccessible, it's not a big issue since the user gets a notice at least.
