Our company switched over to AppRiver about 3 months ago in May 2016, from Sophos' spam filter. Sophos would constantly let spam through, and it was the same spam that other companies were complaining about on the Sophos forums. Some users were receiving 40 spam emails a day (210 users). We contacted Sophos and ran all updates, but still had the same issues. When we switched over to AppRiver, the setup was not complicated. The first 3 or 4 weeks consisted of our tweaking settings, mostly just allowing legit emails stuck in the filter through to users. Since then life has been MUCH easier. Our users receive nearly zero spam emails a week. Every once and a while you get an unwanted email that makes it through the filter, but all you have to do is email your spam to email@example.com and they will dissect the spam and add it to their filter. I really couldn't ask for more. AppRiver has made my job much easier, and they even have an informative interface. It turns out that we receive up to 40,000 spam emails in a single day! It puts my mind at ease knowing they are catching all of these unwanted emails, especially knowing that the encryption/ransomware viruses (Locky, CryptoLocker, etc.) have been on the rise. This has been one of the best IT choices we have made in a long time. Thank you AppRiver, keep up the good work.
