I'd like to ask the experts here what you'd say are some ways and ballpark costs to block people from accessing 'adult sites' in a work environment? Mostly at a PC on the office domain. But there's also wifi they could use.
It's an SBS 2011 Standard domain with 7 users at desktops. There's a low end Cisco router (RW-215). There's 2 wifi VLANs - an office SSID and public SSID supplied by a group of Ubiquiti unifi UAPs
Depending on cost, they'd want to block adult sites on office VLAN for sure, and maybe public VLAN
I haven't deal with this in a while.
I remember Open DNS had a (free?) service that allowed category blocking? But the devices had to use OpenDNS DNS servers. Enforcible for desktops, but not enforable on employee wireless devices and not on people's devices on public wifi
Having not dealt with this in a while, my vision is that it's never 100%? Sites are always popping up - that won't appear on lists of sites to block - and if people are motivated to get to them, they most likely can. If the public wifi VLAN is not site filtered, they can use that. Or heck, they can use cellular if they really need to see porn at work. I would think they just make an employee policy not to go to those sites rather than go through the trouble of technology to get them to behave?
