I'm an IT consultant for several small to medium-sized business. I've mostly use Avast and Malwarebytes for my Anti-virus and Malware protection. For the small offices it's easy to manage, but for bigger offices, keeping track of anti-virus expiration dates is ridiculous (since it will be different based on when they get a new computer) and this week it was proven that I can't rely on the staff to let me know when a registration is expiring. One of the computers was infected with CryptoLocker because he ignored the 30-day daily reminders of Avast expiring. Fortunately, I was able to minimize the data lost to 4 hours to 12 hours by using Shadow Copies and the previous nights backup for the database applications that got encrypted. Please note, they also host their own exchange server (SBS 2011/Exchange 2010 or SBS 2008/Exchange 2007)
So, with that preface, I need a good business management solution that provides virus, malware, phishing, spam, web-content filtering and blocking of potentially harmful sites. For one of the offices, I do have a Barracuda Anti-Virus/Spam firewall, but this is only for email not web-content filtering.
I am considering the following:
Untangle NG Firewall - would order the hardware from them
Dell SonicWall solution - debating between NSA or TZ series for the medium-sized businesses.
I also really like the Barracuda devices, but I'm not sure the benefits outway the cost compared to the others.
I'd greatly appreciate any feedback on the above solutions, especially if you use them in your office or any other solutions that you use that you think may be better than the ones I mentioned.
Thank you in advance.
