The best thing about this product was that it did not make my system slow or laggy! It worked perfectly for me with no problems what so ever in over 6 months use (on different systems).
I have never had any issues using Aneenforce as far back when we used them during an office move/changeover from one ISP provider - which also makes sense given how long they've been around now too.. We would definitely recommend allotnetennforcement products if you're looking into something like Anenevetor but be prepared because their support team can sometimes take awhile getting answers out there!! Make sure your needs are very specific before choosing anything else though otherwise other options may fit better than allote net enforecer does specifically regarding internet usage monitoring & control via software only without hardware involved etc.
