Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"Anti-Spam and Advanced Malware Protection are the most valuable features... and we also have the option to block Zero-day attacks.""Cisco Secure Email Cloud Gateway has allowed our users to be able to concentrate on the emails that they do receive. Previously, our users had to deal with nine million additional emails across the organization, which is nearly 1,000 emails per user to have to deal with a month. That's a massive amount for our staff to deal with and probably several hours of their time. We have a lot of clinical staff, being a hospital. We want to make our staff as productive as possible. By removing a lot of that spam and phishing type emails, this allows them to do their job.""The filtering is definitely better at catching both spam and malicious messages, and there's a lot of extremely granular ability for setting up rules. You can do it the way you want to. The Microsoft solution tends to be pretty limited in how it allows some of that to be done.""The added value of it is that every migration to a new version is initiated by the Cisco version itself, so that is a bunch of work that you don't have to do on the Cisco ESA system on-premise. As it becomes a safe platform, you don't need to invest anything in your own data center or in your upgrade path.""It has an intuitive, clear graphical interface where you can deploy your policies and understand the overall flow. There are a lot of things that you cannot handle on the graphic interface, like message filters. For this, you need to go to a lower level where you have more power, like command line interface. So, this solution has the best of both worlds. There are not a lot of bells and whistles. It is more practical with access to most features that you can configure.""There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails.""The solution is very configurable. It has enabled us to configure some specific filters to stop emails that general configurations didn't stop. It's a powerful solution. It can analyze a lot of emails simultaneously, with no problems of capacity or system load.""It is doing its work. It is doing what it was actually designed to do. It has ensured we don't have business email compromises, and it has also ensured that our brand Galaxy is unique all year round."

"They have a feature called CDR, Content Disarm, Reconstruction, click protection, and DLP for encryption purposes.""Its performance is very good and it is stable.""When combining this solution with other Fortinet products, such as FortiGate, it integrates well and provides a comprehensive protection package.""FortiMail is extremely flexible and very easy to learn. Compared to other email security products that we've tried, it is mainly the ease of configuration that makes FortiMail valuable to us.""The integration with FortiSandbox is good, and something that we utilize often.""It actually filters the compromised emails when on a network layer itself.""The most valuable features are the endpoint defense features, it is very secure.""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."

More Fortinet FortiMail Pros →

"The deployment capability is a great feature.""The most valuable feature of Microsoft Defender for Office 365 is the ease of use.""The basic features are okay and I'm satisfied with the Defender.""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 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.""It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have.""Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links.""The good part is that you don't have to configure it, which is very convenient."

Cons
"The interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration.""I use the search all the time. Sometimes, it is hard to search for things and things are hard to find. People come to me all the time, saying, "This email didn't get through." Then, I go searching and don't find it on the first search. You have to think about alternative searches. I don't know if there is an easier way that they could help to find things. I don't know how they could simplify it, because now everybody else is using the cloud and everything is coming from Office 365, or whatever. It is just not the same environment from years ago where everybody had their own server and you could search easier.""The area of license renewal should be improved. We normally renew our license every year. There is a feature called smart licensing, and I switched from the legacy mode to the smart licensing mode because of what I thought smart licensing does. I thought it would make licensing renewal seamless and very swift, but ever since I've switched to smart licensing, each time I want to renew my license, it is a whole lot of headache. The process is not smooth, and I had to keep calling Cisco TAC to see how the issue can be resolved. At one point, I wanted to revert back to the legacy mode, but I can't revert. Once you switch from the legacy mode to the smart licensing mode, you can't revert. They should improve on the visibility of the smart licensing mode so that it can indeed be smart and easier to use for the license renewal every year. That is one challenge.""The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky.""I would like more functionality and how to use it for Level 2 type staff. The biggest issue is it needs to be easier to use and navigate.""The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear.""We have been struggling in the last month with Cisco encryption and with the S/MIME encryption. I don't know if it is an issue on our side or if these features of the solution are not working very well.""They can do it better with web links, with the URLs. They have a technology called Outbreak but it doesn't work as well as we would like."

More Cisco Secure Email Cons →

"The solution is user-friendly to a degree but the dashboard needs improvement.""What's missing in Fortinet FortiMail is some sandbox information for some of the emails. It's probably configuration-based, where it could be configured on some emails. For example, there was malware in some emails that weren't detected in some of the Fortinet FortiMail sessions, but it should have been configured from my company's end to better catch scam emails, but overall, the solution is okay. At the moment, my company is okay with the current Fortinet FortiMail offerings, but in the past, because of a lack of understanding, my team wasn't able to quickly implement the geographical IP blocking feature. It was time-consuming to implement that feature, but that wasn't a fault of Fortinet FortiMail. The issue was from my team's end, but just by emailing the support team, that issue was resolved, so right now, there isn't any additional feature I'd like added to Fortinet FortiMail.""My customers frequently ask to have detailed documentation for FortiMail and FortiWeb as they have in FortiGate. What they currently have is not enough.""It's difficult for me to talk about areas for improvement in Fortinet FortiMail because I'm the general manager of the company and I'm an engineer with knowledge about the solution, but I'm not deeply involved in its implementation. As I mentioned previously, Fortinet FortiMail is also being used within the company, and I'm happy with its functionality, but sometimes, attacks pass and avoid the Fortinet FortiMail filters, but those could be very sophisticated attacks. There could still be an improvement in the filtering feature of the solution, though the security of Fortinet FortiMail is okay for me because I believe you can't implement one hundred percent security in any solution. The initial setup for the solution also needs improvement. The setup is supposed to be simple, but then the customer starts to complain that some of the false positive emails are reaching quarantine, so my team has to configure it again. There have been instances when Fortinet FortiMail rejects valid emails because some of the service partners of the customer have not been configured accurately, so the system considered valid mails as attacks to be quarantined, so aside from improving the filters, there should also be an improvement in the categorization of emails in the server. My team has to modify the configuration so that valid emails could pass and for Fortinet FortiMail to correctly filter the SPAM traffic. A feature that could be added to Fortinet FortiMail in its next release is advanced AI, so it can analyze and decide accurately on which mail is valid and which mail is SPAM.""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.""I think the security of the product could improve.""It is not easy to install.""The solution could be improved by providing a virtual machine facility with a complete set of options in the VM setup."

More Fortinet FortiMail Cons →

"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.""The custom alerts have to improve a lot.""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.""Too many false positives and lacks an accurate capability to detect malicious SharePoint sites.""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.""They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not.""Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added.""This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."

Pricing and Cost Advice
  • "The licensing was all transferred."
  • "Compared to Cisco's on-prem service, the cost is the same, but you don't have to pay for the hardware and you don't have to maintain the system, as far as upgrades and hardware failures are concerned. It is cheaper to operate on their cloud service than it is to operate with their on-prem service."
  • "Cisco Secure Email and the support are priced well. It's not cheap, but there are other solutions that offer less and cost so much. For example, Microsoft is more expensive than Cisco."
  • "There are additional fees for adding features."
  • "At times, we feel the pricing is a bit too high, but then, there is also room for discounts. We enjoy a lot of discounts, and that is why we are still with them. There are no costs in addition to the standard licensing fees."
  • "In my previous organization, avoiding four instances of CryptoLocker within an estimated six month period is approximately $600,000 in lost time and effort. Our five year cost was about a million dollars, and the four outages that we had equated to 65 percent of that five year cost."
  • "It is a super big router that costs a few hundred thousand dollars."
  • More Cisco Secure Email Pricing and Cost Advice →

  • "It's not as that expensive with the competitive different brands. The products sell a lot."
  • "In terms of licensing, we are using a virtual machine license for the single virtual server which it runs on. Doing it this way enables us to cut costs by only licensing FortiMail for our exact use case. If you need to expand in future, you can later buy extra licenses per virtual machine."
  • "There is a license required for this solution and it is on an annual basis. I am satisfied with the price."
  • "The fees for Fortinet FortiMail can be complicated. However, overall the pricing is fair."
  • "There is either an annual or six-month charge to use this solution. Fortinet FortiMail is cheaper than Proofpoint or Cisco Security, or other email security appliances."
  • "The pricing is good."
  • "There is a license required for this solution."
  • "Fortinet FortiMail has an annual license agreement."
  • More Fortinet FortiMail Pricing and Cost Advice →

  • "It's a user-base subscription."
  • "From the pricing point of view, like any other product in the market, there is scope for negotiation."
  • "Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
  • "For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
  • "Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
  • "Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
  • "The solution saves money so we have seen a return on investment."

    Reviews from Real Users

    Fortinet FortiMail stands out among its competitors for a number of reasons. Two major ones are its powerful anti-virus tool and its robust spam protection capabilities.

    Flamur P., head of security management at Ipko Telecommunications, writes, "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."
