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

"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"Sophos Email provides both inbound and outbound filtering."
"The most significant aspect is the response filtering concerning attachments and links."
"The deployment is very easy. It's quite straightforward."
"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."
"The feature of Sophos Email that we find most effective for detecting suspicious emails is primarily based on their signatures."
"It has enhanced our approach to tackling malware and spam. It is a reliable product with a good user interface."
"The best thing about it is the logs."
"Sophos Email is in the cloud and integrated with its firewall."
 

Cons

"FTP server and TRUST Manager functionality."
"Malware needs improvement."
"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."
"Sophos Email could improve DLP features."
"The tool's pricing is expensive. In its future release, the tool should make reporting easier to view."
"Enhancing rule creation and customization features would provide users with greater control over their email security settings."
"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."
"The tool's integration becomes an issue when the internet connection is weak."
"It was sometimes hard to find the settings in the solution's interface."
"Their technical support is slow to respond."
 

Pricing and Cost Advice

Information not available
"The tool's pricing is medium."
"The product is cheaper compared to other solutions."
"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 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."
"We use exchange licenses, for which we get immediate support from Sophos."
"Sophos Email is a little expensive for us, but it's necessary. We have a subscription and renew it every three years."
"The pricing is quite reasonable, with a fixed cost and no additional charges."
"I would rate the pricing of Sophos Email as a six. It is considered affordable as a standalone product, and there are no additional costs besides licensing. The pricing is fixed."
