One of the add-ons you might find with Mac security products, although also commonly sold separately, is Mac VPN (virtual private network). For many users these are of interest because they can mask your location and allow you to view things (like streaming series) that are otherwise off-limits in your location. But they also have a very real benefit for security, protecting your internet connection by encrypting it, which is especially useful when using public Wi-Fi networks. In this day and age we should all be using VPNs and, while we'd recommend buying a dedicated Mac VPN product, one built into your antivirus software is better than nothing - just be prepared to be nagged to upgrade to the full product.
