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.

Pros

"The most important feature is data processing."
"The most important feature is data processing, and I like the dashboard and the undo or multi-call feature of Microsoft Purview Customer Lockbox."
"The feature of Sophos Email that we find most effective for detecting suspicious emails is primarily based on their signatures."
"It is really good for anti-spam, anti-malware, and especially for ransomware."
"I found the user interface friendly."
"Good VIP protection, time of click protection and the Sandstorm feature."
"The anti-malware, risk scanning has been pretty spot on."
"The best thing about it is the logs."
"I would recommend Sophos Email to both end-users and other entities that want to protect their emails."
"When you say email security, it's about everything, incoming email, outgoing email, spam, phishing emails, unwanted marketing emails. You can set rules, but the main feature of Sophos Email is to make sure you don't get hacked. 95% of people who are hacked do not get hacked by typing the router password. They are hacked from the inside out, which means they send you a document that is a zero-day attack, you open it, nothing happens, but technically the attack is running in the background of your computer. This is how they gain access to your PC."
 

Cons

"The pricing for personal users is not cost-effective. It feels expensive for individual expenses."
"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 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."
"It was sometimes hard to find the settings in the solution's interface."
"Sophos lacks real-time support, which would be a help to us."
"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."
"Some existing functionality in the product needs better articulation in how data is displayed."
"Sophos Email can improve mail security."
"The tool's pricing is expensive. In its future release, the tool should make reporting easier to view."
 

Pricing and Cost Advice

Information not available
"Sophos Email is priced lower than its competitors."
"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 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."
"The tool's price is reasonable. On a yearly basis, there is a 20 percent increase in prices, but it is not an issue."
"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."
"I rate the price of Sophos Email a four out of five."
"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."
"Licensing is paid on a yearly basis."
