Looking for a recommendation on a small business firewall for a very small office. There will be one server, two desktops, one laptop, and a total of five users. I'm looking more for a solid hardware firewall that doesn't necessarily have all of the UTM bells and whistles; however, the ability to block URLs or certain websites that could potentially distract from productivity would be great. VPN is a must for remote access. I was eyeing up the Sonicwall TZ 105, but the additional add-ons are almost more than the device costs. I've played around with pfsense on a spare machine at my home, but one thing that concerns me about a white-box firewall is if it is HIPAA-compliant. What would you recommend? I am not opposed to a linux firewall, if you can convince me that it would be the ideal solution. A general budget would be somewhere under the $500 mark. Thanks!
