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."
"I have found Sophos Email to be scalable."
"Sophos Email is a stable solution."
"I found the user interface friendly."
"Good VIP protection, time of click protection and the Sandstorm feature."
"The most valuable feature is its email security."
"Sophos Email is in the cloud and integrated with its firewall."
"The most significant aspect is the response filtering concerning attachments and links."
"The filtering capabilities are precious and far superior to others I've used. It's intuitive in what it pushes to quarantine, and users can quickly review, free, or delete items without needing an administrator, making it ideal for a multi-user environment."
 

Cons

"FTP server and TRUST Manager functionality."
"Malware needs improvement."
"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."
"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."
"Sophos Email has few improvements to implement, including the handling of incoming emails in the systems. It needs to add additional feature that helps in enhancing the scanning processes of these emails. While adding these features, it should work towards improving the current features also."
"Sophos Email could better detect fake emails, especially when the domain names are similar. It needs to improve spotting spoofed domains, like when one letter differs in a domain name. It also needs to incorporate AI detection. Barracuda detects suspicious emails better. However, malware scanning is better in Sophos Email."
"The product could include all the essential features and capabilities, similar to the on-premise, server-based version."
"The tool's integration becomes an issue when the internet connection is weak."
"The tool’s stability should be improved."
"Lacks visibility into spam emails."

"I rate the price of Sophos Email a four out of five."
"Sophos Email is priced lower than its competitors."
"The tool's pricing is medium."
"It falls somewhere in the middle—it's not excessively expensive nor very cheap."
"The platform is inexpensive. It offers a cost-effective licensing model. We purchase its yearly license."
"The pricing is quite reasonable, with a fixed cost and no additional charges."
"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."
