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.

Ensures continuous protection with real-time scanning of emails and mailboxes
ScanMail needs improvement in its reporting, as it is currently weak in some areas. Additionally, the response time of their technical support is slow and needs enhancement. Overall, Trend Micro's technical support has deteriorated, and pricing is another area that requires attention. The list pricing is high, and we lose deals against competitors because of this. Trend Micro should consider reducing their prices, especially for large customers.

Quotes from Members

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

Pros

"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."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"It's all running in the backend, so it doesn't affect the app functionality."
"The initial setup of Microsoft Exchange Online Protection was easy."
"Microsoft Exchange Online Protection (EOP) is used essentially for email filtering, acting as an anti-spam and security product for email."
"The product protects against malware."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"The most effective feature of ScanMail is its real-time antivirus behaviors, particularly when it scans URLs."
"I like that Trend Micro ScanMail is very effective and quite strong."
"What I like the most about Trend Micro ScanMail is its easiness."
"The analysis part is good."
"It does the job. Even when our clients have a very high rate of emails per second, there has been no problem."
"I find Trend Micro ScanMail to be a stable solution, and I would rate its stability as nine out of ten."
"The pricing of Trend Micro ScanMail is average, which is fine."
"Trend Micro ScanMail is scalable at different levels."
 

Cons

"It would be helpful for customers if Plan 1 features were included with EOP."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"The licensing can be on the expensive side, especially in the cloud space."
"The tool is not 100% stable."
"The solution lacks to elaborate on its spam policies."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"The price could be better. I think it's pretty good compared to other solutions as far as the features are concerned. It basically covers most of the stuff which we require for email security. But it would be better if they made it a little cheaper and more cost-effective. That would make it easier for us to sell it."
"ScanMail needs improvement in its reporting, as it is currently weak in some areas."
"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."
"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."
"Even Trend Micro ScanMail support staff are not familiar with this product."
"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 tool's pricing is excellent."
"The product is expensive."
"The product's pricing is competitive for the US market."
"It's a high price."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The solution is expensive but is backed by Microsoft's reputation."
"It is a low-price solution."
"The price could be lower."
"Its price is okay. It is not too high."
"It's a yearly subscription, but the price could be better."
"It is an expensive solution. I rate the pricing a seven out of ten."
