This is a dud product with inferior spam filtering
This is a dud product with inferior spam filtering versus alternatives like SpamHero, and the continuity feature is essentially marketing fluff. Failed deliveries, for example, they don't count it as an issue so those messages won't be queued for another delivery attempt. As I understand it from talking to their support, if the server pings or sends any response at all, then Mail Assure will not keep a copy. It will also weirdly mark messages during that outage as rejected, so it's not like Mail Assure doesn't know that the message never reached the user(s).

Comprehensive detection has protected email traffic and now simplifies endpoint security work
Sophos Email security is the primary product I use. It scans all your inbound and outbound email for malware. It also has a capability for looking for phishing and spear phishing content and blocking it. Email has an extended capability that includes what's called a secure web gateway. All user traffic gets managed through that, making it a combination product. The version of the product you run determines which features are available. Reporting is competent. There is scope for more improvements, which they will do as they do every year regularly. They keep updating the product. Reporting gives you the relevant details of what is happening, so it's mature on that front. The main benefit is security for your email. The beauty of the Sophos system is that the XDR functionality runs across the system. Sophos, Trend Micro, and Microsoft are the only three that have a very strong system with this concept. XDR stands for extended detection and response, and it's a technology where the system automatically exchanges security signals between the endpoint, the email, and other similar products of the same brand. If you have Sophos Endpoint and Sophos Email, you have very good connectivity from the endpoint to the cloud at the email level and to some extent onto the browsing traffic. You have a very rounded security aspect.

Pricing and Cost Advice

Information not available
"The solution is expensive."
"The pricing could improve by having additional discounts. For example, when customers buy have more than 50 or more users, there should be additional discounts."
"It falls somewhere in the middle—it's not excessively expensive nor very cheap."
"The pricing is affordable, so I’d rate it around a four out of ten on the pricing scale. We pay about fifty pounds a month, including hardware so that costs may differ without it."
"Sophos Email is priced lower than its competitors."
"There is an additional fee for their central managed console."
"Most of our clients are on a perpetual license. If there is a budget issue, they can choose a subscription. However, most of the clients choose the perpetual license."
"Sophos Email is a little expensive for us, but it's necessary. We have a subscription and renew it every three years."
