Provides reliable real-time email protection and offers competitive pricing features
Regarding Kaspersky Security for Mail Server, I have not compared with other solutions, but I will compare and provide feedback. It is a reliable and fast security solution, and I can say it blocks better than other competitor software. Kaspersky Security for Mail Server has support for Windows and Linux, but regarding improvement, I have to dig deep and will have to do research on that. I have not checked into much detail about what can be better in Kaspersky Security for Mail Server. I have checked in general. If given some time, I can check and compare with other solutions. Regarding Kaspersky Security for Mail Server, I have found this is quite a good solution. It has a good response and good detection capability.

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

"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The most valuable feature is the straightforward setup."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"Our client recently received many emails, and their employees didn't realize these emails were phishing attempts. Consequently, they clicked on them and fell victim to the attack. Therefore, it is important to secure their system with Sophos Email Security."
"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."
"It is a stable solution...It is a scalable solution."
"The solution protects users from phishing links and spam."
"The anti-malware, risk scanning has been pretty spot on."
"Sophos Email provides both inbound and outbound filtering."
"It has enhanced our approach to tackling malware and spam. It is a reliable product with a good user interface."

Cons

"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"The solution is not 100 percent stable and that can use improvement."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"The solution's technical support is slow and unresponsive. You need to book time in order to get support."
"It was sometimes hard to find the settings in the solution's interface."
"I would like to see improvements in the initial setup process, ensuring better compatibility with diverse customer infrastructures."
"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 sandboxing and spam control features could be improved."
"Sophos Email can improve security."
"The tool’s stability should be improved."
"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."
