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.

Secure email management improves through advanced filtering and dynamic virus scanning
Fortinet FortiMail offers capabilities like settings for mail delivery, mail filtering, spam controls, and email bursting prevention. It also allows for email forwarding, dynamic filtering, and scanning based on virus signatures. I can set varying levels of security. The tool is flexible and provides essential features for mail security and management.

Useful for collaboration and storage but improvement is needed in API integration
The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory. I think IceWarp needs to improve in a few areas. They have two types of admin consoles - a web-based one and a remote one. I'd like to see these combined into a single web-based admin console. The log reading and information system also needs improvement. The current way of showing incoming and outgoing logs isn't very clear. For new users, it's hard to understand these logs, especially compared to Office 365 and other systems with easier-to-read logs. They should also add an export option to get all logs with a single click whenever we need them.

Quotes from Members

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

Pros

"The stability of Microsoft Defender for Office 365 is fantastic."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"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."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"Since we have started using the solution, there have been fewer compromises."
"The email protection is excellent, especially in terms of anti-phishing policies."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"Fortinet FortiMail is a complete product addressing mail security concerns. It helps to know spam subscriptions and create restriction policies."
"It can block a lot of fake emails."
"Fortinet utilizes specialized processing units, which network faster and sample more efficiently compared to others."
"The number of false positives is minimal."
"It actually filters the compromised emails when on a network layer itself."
"The integration with FortiSandbox is good, and something that we utilize often."
"The antiphishing capabilities are very good."
"The most valuable aspects of this solution are that it protects us from spam and phishing attacks. We had a lot of attacks coming in and then we deployed this solution and they stopped. We no longer have any spam or phishing issues."
"An effective, functional, very good tool for controlling resources."
"The product is used very extensively in my company since we have around 1,500 users using it. Also, there is no requirement for any administrators to manage the product by the people who own the solution."
"The groupware module is the most valuable feature."
"The most valuable feature of IceWarp is the chat rooms and file-sharing, they are useful. It is convenient that everything is in one place. You can easily share and collaborate documents, making the program's unity a significant advantage."
"It's scalable and stable."
"The solution has a very good log-in to the UI when compared to other solutions."
"The TeamChat feature has been really good for our email management. It lets us collaborate, share files, and invite guests like Google Spaces or Microsoft Teams. I like the two-factor authentication for security. However, they need to improve their document collaboration tools, as their Word, Excel, and PowerPoint features are basic compared to Microsoft and Google."
"IceWarp has multiple applications that are easy to use for many people."
 

Cons

"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"The GUI is sometimes slow to fetch the device report and could be improved."
"Configuration requires going to a lot of places rather than just accessing one tab."
"The custom alerts have to improve a lot."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"We need to be able to whitelist data at the backend."
"Sometimes, the tool flags legitimate incoming traffic as spam."
"I would like the integration to be easier."
"The solution doesn't scale easily."
"The logging information is sometimes not clear or easy to understand."
"The statistics and BI in general could be improved."
"Fortinet FortiMail's pricing could be improved."
"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."
"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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"The exchange compatibility mode is rather limited. Their technical support can also be better. They only provide online support, and there should be some option for escalating."
"Our customers sometimes have problems receiving mail."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"The tool's configuration capabilities are not straightforward. Apart from that, if I want to archive emails into a vault so that they can be retrieved again later, the integration doesn't work, and IceWarp crashes."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"The solution needs improvements in security, particularly regarding document management."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
 

Pricing and Cost Advice

"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The pricing is normal. Considering its popularity, it's not overpriced."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"The license is expensive because the cost is based on the number of users."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"It's a user-base subscription."
"The licensing model for this solution is better because it is based on the box and not the number of users."
"Fortinet FortiMail is inexpensive."
"The pricing is on the higher side."
"Price-wise, you get what you pay for in Fortinet FortiMail. Apart from the licensing costs, no additional expenses are attached to the solution's pricing."
"In the future I would like it if there's a possibility to lower the price of the bandwidth and UTM. It is quite expensive."
"The price is acceptable for the support license it includes."
"The pricing is good."
"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."
"The license is based on the number of users."
"Pricing and licensing is very competitive and in some cases, cheap."
"There are various licensing plans available based on geographic zone."
"The solution is priced well."
"I would rate the pricing and eight out of ten."
"Costs far less than other solutions."
"Our licensing is on a yearly basis. There were no additional costs."
"I don't see any challenges for the Indian market. For example, 1 GB is available for around 399 INR, and 2 GB for 499 INR. They offer a range of plans, from basic to professional and enterprise, with multiple features. IceWarp's aggressive pricing is competitive compared to other market solutions like Zoho and Microsoft. One significant advantage is that IceWarp does not impose user capping like Google and Microsoft, which allows for substantial cost savings and flexibility in user conversion."
