Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

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.

Quotes from Members

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

Pros

"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"We use a few features for web proxy, and another feature is the email content filter and malware for our internal policy in the email content."
"Go for it! I think it's an excellent product with great technical support."
"It provides security to both on-premises and Azure infrastructures."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
"The solution's stability is very, very good. I didn't face any problems in the last year."
"We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features."
"The security features provided by Microsoft are robust."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"It is an easy solution."
"The scalability is pretty good; it does what it is supposed to do."
 

Cons

"FTP server and TRUST Manager functionality."
"I am not satisfied with Clearswift because of the lack of customer support."
"Malware needs improvement."
"The reporting needs a little bit of improvement."
"The security compliance features need to be improved. Sometimes, a client's mailbox becomes full because of retained information and not because of mail. I would like to see improvement in block rules as well."
"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."
"I think the implementation could be more streamlined."
"The product could be more stable. Microsoft products could be more stable because sometimes, even though they are updating some things, we cannot find those updates."
"Microsoft Exchange Online Protection is quite a difficult product."
"Performance and speed should continue to be improved."
"Microsoft has some training portals, but more could be developed."

"It is a low-price solution."
"Apart from the license fee for the solution, there are no additional costs."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."

"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
