Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.

Has struggled with poor documentation and limited tuning options but supports basic protection needs
The major limitation of this product is that their documentation is very poor; their documentation is extremely poor. Their support is very poor for this product, and the solution is average. To be honest, it's not that effective. Their Threat Scan Engine has features that don't work properly; they have features that really don't work properly. Their solution provides writing style verification, but this solution comes with false positives 60% of the time. There is no way from their portal to fix it; you can either turn it off or turn it on. The solution has many bugs. I will recommend Microsoft first for replacing Trend Micro ScanMail, then Barracuda, but the problem with Barracuda is that for impersonation solutions, it doesn't work well. There are many features, but you cannot tune the product. Being able to tune a product is really important; such as adjusting settings to be aggressive, minimal, or to exclude certain things. These are the most important considerations when purchasing a product. When impersonation is needed, but there are false positives, there should be an option to tune the product. Barracuda and Trend Micro Deep Security lack this feature, which is pathetic.

Quotes from Members

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

Pros

"It provides security to both on-premises and Azure infrastructures."
"The scalability is pretty good; it does what it is supposed to do."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"With Microsoft Exchange Online Protection, if malware is attached to a mailer, it's very easy to go into the incident alert and find out what's happening with that identity and the mail."
"Microsoft EOP's most valuable feature is a shared mailbox."
"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"It is useful for local users and our company because we use Microsoft 365."
"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."
"The analysis part is good."
"I like that Trend Micro ScanMail is very effective and quite strong."
"What I like the most about Trend Micro ScanMail is its easiness."
"I find Trend Micro ScanMail to be a stable solution, and I would rate its stability as nine out of ten."
"Its integration with mail platforms is valuable."
"The most effective feature of ScanMail is its real-time antivirus behaviors, particularly when it scans URLs."
"Trend Micro ScanMail is scalable at different levels."
"It does the job. Even when our clients have a very high rate of emails per second, there has been no problem."
 

Cons

"The tool is not 100% stable."
"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
"Not all settings can be configured automatically and most still require manual configuration. However, there is an automation tool available that can be used to input all the configurations either as a script or a tool it would be helpful."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"The product needs more granularity. Some features, like encryption, are not available."
"The biggest issue that I experience is that Microsoft keeps moving things around, and it's very inconsistent as to where you find the information when you're trying to work on different pieces."
"The price could be lower."
"Our Exchange system is very locked down and secure, yet we still got hacked."
"Even Trend Micro ScanMail support staff are not familiar with this product."
"Its user interface is pretty old-fashioned, and sometimes, it's hard to find the features that you are looking for. The user interface definitely needs some improvement."
"The weaknesses of Trend Micro ScanMail are that it doesn't fully protect ad-based web access and lacks proper security for Outlook, iOS, and web browser access."
"The sandboxing part can be improved."
"ScanMail was one of the best solutions a few years ago, but it is no longer the best solution because of its old-fashioned management console. Customers associate it with something that is old because there is no change in the management console. It has old icons, and it is not fresh enough. It is also not easy to use or play with. The report engine is also old-fashioned. Customers want something easier, quicker, and cleaner."
"The price could be better. But it would be better if they made it a little cheaper and more cost-effective."
"ScanMail needs improvement in its reporting, as it is currently weak in some areas."
"I believe there is room for improvement in better signatures, better reporting features, and more insight into the spam emails database."
 

Pricing and Cost Advice

"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
"The price could be lower."
"The product is expensive."
"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."
"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."
"Online Protection is fairly expensive."
"The solution should reduce the cost."
"It is an expensive solution. I rate the pricing a seven out of ten."
"It's a yearly subscription, but the price could be better."
"Its price is okay. It is not too high."
