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

"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."
"A stable solution."
"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."
"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 anti-malware, risk scanning has been pretty spot on."
"It is a stable solution...It is a scalable solution."
"The main use case for Sophos Email is its robust security features; we are effectively blocking spam and phishing attempts, and we have strong control over these aspects."
"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."
"Sophos Email offers encryption and malware protection, provides visibility into emails, has 99% accuracy in catching spam, enhances organizational safety, integrates with various vendors like Microsoft, is deployable with any email service, prevents data loss, features authentication rules, synchronizes with Active Directory and Azure, and includes a self-service portal. The product is very flexible."
"The tool's most valuable feature is the anti-spam detection filter. Its threat email intelligence features help to identify email data."
"Good VIP protection, time of click protection and the Sandstorm feature."
 

Cons

"FTP server and TRUST Manager functionality."
"Malware needs improvement."
"I am not satisfied with Clearswift because of the lack of customer support."
"The pricing could improve by having additional discounts."
"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 solution's technical support is slow and unresponsive. You need to book time in order to get support."
"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."
"Their technical support is slow to respond."
"The tool has some performance issues and bugs, making it an area where improvements are required."
"A lot of legit emails get quarantined."
"The tool's integration becomes an issue when the internet connection is weak."
