Offers clear vision on the clear side of what is being blocked and easy to use but a bit old-fashioned GUI
I would rate my experience with the initial setup a four out of ten when one is difficult, and ten is easy. It's difficult initially since it's an on-premise solution. So it's a bit difficult. So the initial assessment took a few days, and then the deployment was a couple of days. It is on-prem. That is also one of the improvements you need to make on the cloud. Most of the people like things to be on the cloud. You don't have the burden of setting up things on-premise.

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

"The product's most valuable features are spam protection and artificial intelligence."
"I like that it doesn't hold emails for any reason; it sends out notifications to the user as well as administrators. So we have a clear vision on the clear side of what is being blocked and in time as well."
"Microsoft Exchange Online Protection (EOP) is used essentially for email filtering, acting as an anti-spam and security product for email."
"We like the holding facility that is available for potentially suspicious URLs, which allows a real-time review to be performed before the email reaches a user's inbox."
"It provides security to both on-premises and Azure infrastructures."
"We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features."
"Microsoft EOP's most valuable feature is a shared mailbox."
"The initial setup was easy. The configuration process is very straightforward."
"It's definitely scalable."
"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."
 

Cons

"The technical support services and stability need improvement as well."
"There is room for improvement in GUI because it is a bit old-fashioned."
"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."
"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."
"When you're using a Microsoft product solution, you can scale it, but if you're not, there are limitations."
"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
"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."
"The solution must improve the user experience."
"The tool's classification for bulk email is cumbersome."
"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."
 

Pricing and Cost Advice

"The pricing is in the middle. Compared to other products, it should be five out of ten, where one is cheap and ten is expensive."
"It is a cost-effective product."
"The solution is expensive but is backed by Microsoft's reputation."
"It is a low-price solution."
"It's a high price."
"The product is bundled with Microsoft 365."
"The solution should reduce the cost."
"The tool's pricing is excellent."
"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."
"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."
