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.

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.
Nigus Machin Amare - PeerSpot reviewer
Offers advanced protection from email-based attacks and consistently blocks spam
The most valuable features are Fortinet FortiMail ( /products/fortinet-fortimail-reviews )'s ability to protect from advanced features of email-based attacks, including protection against ransomware and malware attacks. It is especially effective in blocking spam through standards like wrong source IP for email-based attacks. Its high scalability and stability, especially for financial institutions, are noteworthy.

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 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"The product's scalability is good."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"The product is not resource-intensive."
"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 for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"The good part is that you don't have to configure it, which is very convenient."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare DDoS mitigates DDoS attacks."
"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."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"The blocking feature is very good."
"I'm very satisfied with the environment and the dashboard."
"Fortinet FortiMail is easy to use and the detection rate is very good. You can customize content filters and profiles are done easily. Additionally, there is a sandbox integration feature that is good."
"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."
"FortiMail effectively filters all emails coming to our mail server, blocking malicious ones automatically."
"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."

"Fortinet FortiMail's most valuable features are its performance and security."
"Technical support is great. They are able to look at their patches and offer quick responses. We even have an account manager in the Middle East. They are very good."
 

Cons

"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"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."
"Configuration at the mid-level could be improved for the support team."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"You should be able to deploy Defender for every subscription without the need to add servers."
"The XDR dashboard has room for improvement."
"The custom alerts have to improve a lot."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"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."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"Lacks a VPN feature to provide a secure connection to the data center."
"Our subscription plan for the solution has a limitation of bot signatures."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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."
"They don't have a person to provide support for customers using the solution under their free plan."
"The sandboxing features are not well done in Fortinet FortiMail, making it an area of improvement."
"Fortinet FortiMail should allow more flexibility with the content rules."
"The solution could be improved by providing a virtual machine facility with a complete set of options in the VM setup."
"The support could be faster because we've been receiving complaints from customers, they say that when they raise a ticket, it doesn't take 24 hours to respond, sometimes the support responds after three days. This is a lot of time."
"Fortinet FortiMail's pricing could be improved."
"Sometimes, authentic emails get blocked by the solution's firewall."
"The main area for improvement is the pricing."
"The biggest room for improvement would be the deployment. It will be hard for someone who doesn't understand the interface to deploy. If you understand it, you can find your way around the problems."
