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 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.

Provides good identity proxy features, but sandboxing and spam control features could be improved

Sophos gives you a feature set to manage your on-premises firewall on the cloud. I just integrated my on-premises firewall into the cloud, and I can manage the tool through the cloud as well if needed. I recommend using Sophos Email as a proxy. For email gateways, I advise choosing mature products with rich feature sets, like Trend Micro or CrowdStrike. The solution's integration with other tools is very simple. I easily integrated Sophos Email with my Active Directory. My organization needs a WAF with a limited feature set, which we use through Sophos. Purchasing additional WAF will be costly, but I get sandboxing and WAF features free of cost with Sophos, which is included in the license. Overall, I rate the solution a seven out of ten.

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 feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."

"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."

"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."

"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."

"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."

"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."

"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."

"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."

More Microsoft Defender for Office 365 pros

"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."

"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."

"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."

"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."

"I find the comprehensive features of Sophos Email most valuable."

"It is a stable solution...It is a scalable solution."

"Endpoint and server protection are very effective."

"It's easy to use and the configuration is straightforward."

"Sophos Email is in the cloud and integrated with its firewall."

"I cannot guarantee any email by its name. It can be spam. Sophos Email helps to double-check whether an email is spam or not. It has a dashboard which gives an overview of the alerts."

"The anti-malware, risk scanning has been pretty spot on."

"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."

Cons

"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."

"We need to be able to whitelist data at the backend."

"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."

"The phishing and spam filters could use some improvement."

"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."

"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."

"The UI needs to be more user-friendly."

"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."

More Microsoft Defender for Office 365 cons

"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."

"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 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."

"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."

"The tool has some performance issues and bugs, making it an area where improvements are required."

"Email installation could be more user-friendly so that it can be done without involving the partner"

"The product could include all the essential features and capabilities, similar to the on-premise, server-based version."

"The tool's pricing is expensive. In its future release, the tool should make reporting easier to view."

"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."

"The installation of Sophos Email could be easier. It's a bit difficult because setting up the email virtually requires some bit of technical knowledge."

"Sophos Email can improve security."

"Lacks visibility into spam emails."
