Featured Reviews

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.
Carlos Alam Hernandez Baruch - PeerSpot reviewer
The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.
Andras Solt - PeerSpot reviewer
Reasonable pricing and good spam filtering but does not offer robust gatekeeping
It's mainly suited for mid-size companies, not for bigger companies like us. We are more than 1,000 people. In fact, we're over 2000 users, so that's why we investigated some other products, and Clearswift, for example. We likely won't increase usage. We're looking at GFI in a year or so.

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 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"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."
"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."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"The solution has different options that can be used to differentiate DDoS attacks."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare DDoS mitigates DDoS attacks."
"Clover is the best product globally."
"This solution is easy to understand and easy to configure."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"It will take the blow rather than our applications should an attack occur."
"Its performance is very good and it is stable."
"The most valuable features are the endpoint defense features, it is very secure."
"We found the initial setup to be mostly straightforward."
"Fortinet FortiMail has a lot of valuable features. It works great. It also has an antivirus feature. Support for Fortinet FortiMail was also great when my team wanted to block some geographic IPs, but couldn't figure out how to do it. The support team provided clear communication on how to resolve that issue. Another valuable feature of Fortinet FortiMail is SPAM filtering which tells you how many spammy emails you've received. Based on my current use cases, I'm happy with Fortinet FortiMail."
"I love the integration between Fortinet products."
"This solution is good for small and medium enterprise companies."
"The GUI isn't hard to use. When we do a demo and explain the features of Fortinet products to our customers, they understand very quickly. They can easily manage their systems without us."
"This excellent email gateway minimizes spam, inspects suspicious emails and isolates infected attachments with little administrative effort."
 

Cons

"Microsoft Defender for Office 365 should be more proactive."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"Configuration requires going to a lot of places rather than just accessing one tab."
"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."
"We need a separate license and we don't know how to get the license that is required."
"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 noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"The initial onboarding was causing us some confusion."
"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"Cloudflare DDoS has poor technical support."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Our customers no longer use Cloudflare because its service is subpar."
"The onboarding process can be improved a little bit."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Sometimes it takes a little bit too long to determine if an email is good or not. If they could shorten that time span, it'd be so much better. It does delay our email, which does not make users happy. That said, I would have to say we have not been blacklisted for quite a while now."
"FortiMail's dashboard is somewhat complex and could be made simpler."
"In the Latin America market, some spam messages use Portuguese language. Some clearly spam messages would be better identified by the anti-spam if not for the language."
"I would like it if the solution could be more affordable."
"The only drawback to this solution is that the firmware is frequently updated, and each update results in downtime."
"ortiMail has some latency issues and sometimes takes time to receive emails."
"The solution doesn't scale easily."
"The main area for improvement is the pricing."
