Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

Quotes from Members

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

Pros

"We are grateful for the solution and its great advances in connecting teams under a secure environment that cybercriminals cannot compromise."
"The program has reduced the dangers related to phishing, malware, ransomware, and other vulnerabilities."
"If we look at four to five years ago, we had close to six or eight people click a link in an email per month. Now, we are probably down to about five or six clicks a year, if not less."
"Spam protection is the most valuable feature."
"The most valuable feature of Avanan is its Anti-Malware solution for Office 365, and box.com."
"I like Avanan's SmartDLP module. It's seamless, and the administrative overhead is low. We aren't a very sophisticated operation. We just want to reduce our exposure, so we find ThreatCloud helpful. Avanan's acquisition by Check Point was beneficial for them."
"Avanan is just outstanding on how efficient and effective their learning modules are to pick up on these different pieces."
"The most valuable feature of Avanan is its effectiveness; when scanning incoming emails for threats it can, in an automated fashion, quarantine suspicious attachments."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"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."
"With both of them working together, we have the perfect solution for mail."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"The most valuable feature is the straightforward setup."
 

Cons

"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"The cost is higher for SMEs, however, the pricing and billing criteria can be lessened to accommodate more willing customers."
"There are some things that they can't remediate. The honest thing is nobody can right now because of the nature of how some of the secure email platforms work."
"The email filtration system is not well set since it sometimes blocks useful emails that are safe."
"There are times when we have false positives."
"Since it periodically identifies ordinary emailers as spam or dubious, they may need some AI logic improvement."
"It should reduce the amount of time needed for thorough scanning."
"The system response in a slow computing device affects performance when sending and receiving emails."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"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 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."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"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."
"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."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
 

Pricing and Cost Advice

"Having the flexibility and modeling to do the pricing that best fits the needs of the organization is incredibly ideal. That is what Avanan does. They know exactly how many users are using it, etc. We can tune the invoicing associated with how we are using the product so we can charge it back to the shows appropriately."
"The pricing of Avanan is reasonable."
"Good pricing arrangement as an SaaS offering."
"The product is not the cheapest in the market."
"Avanan’s price is comparable to Barracuda."
"My company makes annual payments towards the licensing costs solution."
"The solution is not expensive."
"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."
