Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

A stable product that provides security and control over spam and phishing emails
I have a lot of control over spam and phishing emails. I can monitor and manage it from Hornetsecurity’s console. The live tracking system is valuable. We can track every incoming and outgoing email live. We can decide whether to block, release, or quarantine emails. We can also review the emails before releasing them. The product provides 99.9% coverage for email security.
Taha Khaleel - PeerSpot reviewer
A highly reliable solution that provides monitoring capabilities and protection to multiple types of devices
The initial setup of Kaspersky Security for Mail Server is very easy. The initial setup of Kaspersky Security for Mail Server takes around four minutes. The solution is deployed on the cloud and on-premises. For the deployment process, you can buy the solution in a CD form or purchase it directly from the company website and activate it. My company needs managers, engineers, and developers to deploy the solution. The number of people required for the deployment process changes from time to time, so all the staff are included not just for the deployment of the solution but also to make improvements to the solution in the future. You can contact Kaspersky to see if they can provide the solution with integration capabilities for your company by providing you with an open account, which I haven't tried yet, though I plan to try it in the future.

Quotes from Members

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

Pros

"Microsoft Defender for Office 365 is a stable solution."
"Scalability-wise, I do not think there are any issues so far."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"I have a lot of control over spam and phishing emails."
"Hornetsecurity 365 Total Protection is an easy-to-use solution."
"Backup and restore are precious features."
"The best part is, I rarely have to access the portal as everything is set up and tweaked the way I wanted it. But the feature set is incredibly granular and allows for deep levels of customization."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The most valuable feature is the straightforward setup."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"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."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
 

Cons

"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"I'd like some additional features any product can give me to protect our environment in a better way."
"Microsoft Defender for Office 365 should be more proactive."
"You should be able to deploy Defender for every subscription without the need to add servers."
"The phishing and spam filters could use some improvement."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"I guess I would say maybe quick access to training material for end-users. I know partners have access to this but I as an end-user do not have immediate access to new update information."
"The solution’s pricing is not reasonable."
"A reduction of 10% in pricing can be an improvement."
"The pricing is a little high compared to other products."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"The license is expensive because the cost is based on the number of users."
"The product is expensive."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The pricing has become expensive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"The product is very expensive."
"The pricing is acceptable and falls into the medium range, neither cheap nor overly expensive."
"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."
"My company makes annual payments towards the licensing costs solution."
