John Zupancic - PeerSpot reviewer
Vice President / Branch Manager / Senior Technician at Aperion Information Technologies, Inc.
Pricing that is competitive, excellent technical support, and email security
They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried. They are very easy to use. We don't have as many problems with email security. They have some areas that could be improved. For example, we also use Zix email Encryption for email encryption, which was clunky and could be improved, but the email security itself has been excellent.
NancyHartman - PeerSpot reviewer
Business Process Manager/ Educational Technologist at a educational organization with 1,001-5,000 employees
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.

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

Pros

"They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried."
"It's easy to use and user-friendly. Users can also easily release spam emails."
"They are very easy to use."
"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."
"The product protects against malware."
"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."
"We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features."
"We can migrate seamlessly without any disruptions to our operations."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
"The threat management feature includes policies and alerts that are valuable."
"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."
 

Cons

"Technical support is no longer as good as it once was."
"It needs to make sure that the application is up to date with new attacks. They should also send us the demo or introductions for their new incoming features."
"Email security checks contain a small number of false positives."
"It would be helpful for customers if Plan 1 features were included with EOP."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"Performance and speed should continue to be improved."
"It kind of has a heavy footprint in terms of an implementation footprint."
"Our company faces difficulty with Microsoft Exchange Online Protection (EOP) because it's too big, clunky, and difficult for a small client to implement quickly and easily."
"The tool's classification for bulk email is cumbersome."
"The solution can be complex at times. It would be nice to have the on-server version. It needs to improve the stability as well."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
 

Pricing and Cost Advice

"I can rate it five out of ten because there are different platforms that also offer the same services for lower prices. But AppRiver is more flexible."

"It's a high price."
"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."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The price of Microsoft Exchange Online Protection is reasonable."
"The solution should reduce the cost."
