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.

Achieving Seamless Email Security and Encryption while Managing Temporary Email Storage Limits
We continue to use Sophos products and remain with the company. For firewall protection, we use XGS systems. We have provided Sophos Email Gateway for one of our clients. We have integrated Sophos Email with our internal email server, using it for both outbound and inbound traffic. Integration with Office 365 protection for Sophos Email Security works smoothly without any challenges. The solution is totally cloud-based. I recommend Sophos Email for mid-sized companies as it is a good option, though it may not be ideal for large-scale or small businesses. I have not tried incorporating AI technology with Sophos Email yet. I am Bhanu Prakash, Technical Head for Systek Services, and can be reached at b.hanu@teamsistek.com. I am a partner with Sophos. Overall rating for Sophos Email: 10/10.

Quotes from Members

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

Pros

"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
"The most significant aspect is the response filtering concerning attachments and links."
"The solution protects users from phishing links and spam."
"The best thing about it is the logs."
"The platform is scalable when installed on server-based systems."
"The tool's most valuable feature is the anti-spam detection filter. Its threat email intelligence features help to identify email data."
"I would recommend Sophos Email to both end-users and other entities that want to protect their emails."
"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."
"Good VIP protection, time of click protection and the Sandstorm feature."
 

Cons

"Malware needs improvement."
"FTP server and TRUST Manager functionality."
"The solution has not found a way to block certain kinds of phishing emails."
"Sophos Email could improve DLP features."
"Email installation could be more user-friendly so that it can be done without involving the partner."
"Sophos Email can improve security."
"There have been some issues with compatibility and effectiveness, particularly when integrating it with our firewall. The main challenge has been email protection, especially due to compatibility issues and difficulties with log access and email relay configuration."
"The solution should be able to support the cloud environment."
"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."
"Servicing and support are areas with shortcomings where the solution needs to improve."
 

Pricing and Cost Advice

Information not available
"I rate the product's pricing a seven out of ten."
"The tool's pricing is medium."
"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."
"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."
"Sophos Email is priced lower than its competitors."
"It falls somewhere in the middle—it's not excessively expensive nor very cheap."
"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."
"The product is cheaper compared to other solutions."
