Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

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

"We use a few features for web proxy, and another feature is the email content filter and malware for our internal policy in the email content."
"A stable solution."
"Go for it! I think it's an excellent product with great technical support."
"Ability to create your own content-filtering policies with relative ease."
"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."
"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."
"I find the comprehensive features of Sophos Email most valuable."
"There are many features that are important, but among those, the spam protection feature is very valuable. It help us to safeguard the email against phishing and ensures that there is maximum security enabled for our communication processes. It has a huge role in protecting our emails from potential threats."
"Sophos Email is a stable solution."
"Good VIP protection, time of click protection and the Sandstorm feature."
"I found the user interface friendly."
"The speed and stability were fine."
 

Cons

"FTP server and TRUST Manager functionality."
"Malware needs improvement."
"I am not satisfied with Clearswift because of the lack of customer support."
"Sophos Email can improve security. We would like more security for our customers."
"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."
"The solution should be able to support the cloud environment."
"A lot of legit emails get quarantined."
"However, the setup was tricky, particularly with the DNS routing between Microsoft Exchange Online and Sophos cloud services. It took me about four attempts to get it working correctly. Despite that, Sophos Email does everything we need, so we don't require any additional capabilities now."
"While Sophos Email is generally sufficient, one challenge we face is the 24-hour email storage limitation."
"Servicing and support are areas with shortcomings where the solution needs to improve."
"The tool's integration becomes an issue when the internet connection is weak."
 

Pricing and Cost Advice

Information not available

"We use exchange licenses, for which we get immediate support from Sophos."
"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."

"The pricing is quite reasonable, with a fixed cost and no additional charges."
"The product is cheaper compared to other solutions."
"The pricing is fair."
"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."
