Kamran Bhatti - PeerSpot reviewer
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. I have not checked other products, so I cannot give any detailed or specific feedback regarding that. From what I have checked from Kaspersky mail security, it is satisfactory.
Amber Worth - PeerSpot reviewer
Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features are the anti-phishing and anti-spam capabilities."
"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."
"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 feature is the straightforward setup."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"It is scalable."
"The scalability is pretty good; it does what it is supposed to do."
"It offers great security against malware and other threats."
"The email policy configuration options in Microsoft EOP are satisfactory."
"With Microsoft Exchange Online Protection, if malware is attached to a mailer, it's very easy to go into the incident alert and find out what's happening with that identity and the mail."
"It's definitely scalable."
"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."
 

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 solution is not 100 percent stable and that can use improvement."
"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."
"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."
"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."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"Microsoft 365 Defender and EOP policies are stable with the proper license. However, with the basic policy, it's hard to say it's stable due to configuration limitations."
"We would like the solution to have more in-built intelligence in the way that it reviews potential security risks, rather than our team constantly having to update the policies."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"The solution must improve the user experience."
"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
"The security compliance features need to be improved. Sometimes, a client's mailbox becomes full because of retained information and not because of mail. I would like to see improvement in block rules as well."
 

Pricing and Cost Advice

"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"My company makes annual payments towards the licensing costs solution."
"The solution is not expensive."
"The tool's pricing is excellent."
"The pricing of the solution is reasonable."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
"The solution should reduce the cost."
"Online Protection is fairly expensive."
"The price could be lower."
