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."
"The most valuable feature of Microsoft Exchange Online Protection is the accidental release of information protection capabilities, and additionally, the solution is easy to use."
"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 pre-set policies and configuration analyzer are the most valuable features."
"The simplicity and the easy deployment ensure that anybody who has worked on Exchange can easily work on this."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"The initial setup is just a standard process."
"Microsoft EOP's most valuable feature is a shared mailbox."
"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

"The technical support services and stability need improvement as well."
"There is room for improvement in GUI because it is a bit old-fashioned."
"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."
"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."
"The product's end-of-life cycle could be extended."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
"The reporting needs a little bit of improvement."
"Microsoft Exchange Online Protection is quite a difficult product."
"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."
"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."
 

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 falls on the higher or more expensive side of the spectrum."
"The solution is priced high and could be less expensive compared to other solutions."
"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 product is expensive."
"It is a low-price solution."
"The product is bundled with Microsoft 365."
"The solution should reduce the cost."
"The price of Microsoft Exchange Online Protection is reasonable."
