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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The only benefit from Mail Assure is its white label feature and its per-user licensing plus the ability to package archiving and spam protection into a single interface."
"Sophos Email is a stable solution."
"The tool is a good solution for protecting against email attacks and monitoring networks. It supports our compliance efforts and is easy to use and stable."
"The main benefit is security for your email, and the beauty of the Sophos system is that the XDR functionality runs across the system so you have very good connectivity from the endpoint to the cloud at the email level and to some extent onto the browsing traffic, giving you a very rounded security aspect."
"The most significant aspect is the response filtering concerning attachments and links."
"Sophos already has Sandbox, and if any issues are identified, Sophos blocks that particular mail and site instantly, which is why customers are very happy and safe from other attacks."
"I cannot guarantee any email by its name. It can be spam. Sophos Email helps to double-check whether an email is spam or not. It has a dashboard which gives an overview of the alerts."
"It is a stable solution...It is a scalable solution."
"Our client recently received many emails, and their employees didn't realize these emails were phishing attempts. Consequently, they clicked on them and fell victim to the attack. Therefore, it is important to secure their system with Sophos Email Security."
 

Cons

"This is a dud product with inferior spam filtering versus alternatives like SpamHero, and the continuity feature is essentially marketing fluff."
"Sophos Email does not work with split delivery. If I have a domain with 100 mailboxes and want to protect only 50, it is not recommended by Sophos or not possible to configure."
"If they had better deployments for email security, I might rate them higher."
"Lacks visibility into spam emails."
"Sophos lacks real-time support, which would be a help to us."
"Sophos Email can improve security. We would like more security for our customers."
"The main drawback is regarding the technical support."
"Sophos Email could improve DLP features."
"Sophos Email needs to increase the number of promos."
 

Pricing and Cost Advice

Information not available

"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."
"The tool's pricing is medium."
"Sophos Email is neither cheap nor expensive."
"The tool's price is reasonable. On a yearly basis, there is a 20 percent increase in prices, but it is not an issue."
"The solution is expensive."
"It is an expensive solution. On a scale of one to ten, where one is low price, and ten is high price, I rate the pricing a seven."
"It falls somewhere in the middle—it's not excessively expensive nor very cheap."
