We just need to lock down approx. 20 folks at our India office. 9,000 miles and no local HR department means we have to treat them like children I suppose.
What makes you think they simply won't bypass whatever you install?
The fact that they've already signed an AUP and we will fire the shit out of them.
So then why do you need an CF on top of the AUP. . . or are you just really wanting to monitor if they break the AUP and then fire them?
That's what the bosses want. Only 1 person on that side to keep them inline, and he's been interviewing and hiring lately. They've been warned, but in order for that office to be cost effective, we have to block them from shopping online and watching cricket matches.

So doing HR's job because there is no HR onsite. Well that sucks.

I've not used this but Privoxy might work well enough.

@dustinb3403 meh. I've had way more stupid assignments in other "IT" jobs before. Should be basically set-and-forget after whitelisting customer websites. One thing our overseas workers do not do is whine about stuff like filtered internet... that's a huge positive.

What do you have at the site already?
Many firewall devices have this stuff built in now.
I could block anything by category or even strings 'cricket' 'viagra' stuff like that. Any traffic passing through the interface out to the web gets inspected.
Any requests that use these words get blocked with a warning in the browser and logged.
Not quite the same as a dns filtering though. -
You might look at Clouflare. They have a free option and are hosted. I use them on my websites so been a while since I set them up but I think you can do some filtering and white listing.

Also there is no way for most of those devices to block anything HTTPS unless you let the UTM perform MitM on your SSL. This generally causes more problems than it solves.

Oh that is too bad.

We use PiHole. Not as comprehensive, but it's low cost and we can control it.

But PiHole is not designed to block all domains and only allow a whitelist.

For ONLY Whitelist, DansGuardian, then.

Does that do DNS filtering now?

No, but it does whitelist content filtering, which is what he had asked for. You could point it to a DNS filtering service for an additional layer, of course.

Webroot DNS on the endpoints?

DNSFilter and Censornet are products I have used.

Interesting... I'll have to check into that. We already run Webroot endpoint AV.

You can use dnsmasq to achieve what you want. It will block all requests except the domains you choose. You have to add the following to your dnsmasq.conf file.
bogus-priv domain-needed no-resolv # blocks the usage of your resolv.conf file and hosts files, and only allows upstream servers set in this file. # Whitelist - will forward dns request to the following domains server=/mangolassi.it/1.1.1.1 # Dns to which to forward the allowed request
