Before Sophos, I would receive scammers regarding tradeshow lists. People wanted me to pay for lists, but these people weren't actually from the tradeshows. I can now block those, and have received much fewer of those scams. I am also able to open emails within quarantine to view them before deleting, releasing, allowing, or blocking. I use this to my advantage, and am able to make better decisions on what to do with the emails.
Allowing options: I am able to choose from several different options (release, release and allow, delete, block, block and report to Spam)
Warning labels: emails have labels at the top to define if an email is from a trusted sender or the email is from an external sender and may not be trusted. I can block those emails, if I choose to
Quarantine emails: I appreciate the 2x daily emails detailing which emails have been quarantined, and if I would like to release them or delete them
Sophos competes well with other content filtering products. It's categorization is on par if not better than the competition. What stands out most for me is it's ability to integrate seamlessly with the Sophos XG and XDR and Endpoint solutions. Like most network security products, it's often best integration to stick with the same family and the Sophos solution is no different. Because of that, I feel the overall product offering from Sophos (outside of Content Filtering) is on-par with other solutions as well so it's a no-brainer if you use Sophos firewalls, Sophos Content Filtering is the best choice.
