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.

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

"It's easy to use and user-friendly. Users can also easily release spam emails."
"They are very easy to use."
"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."
"The security features provided by Microsoft are robust."
"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."
"It has a really nice web-based administration console."
"The threat management feature includes policies and alerts that are valuable."
"I like the product's ZAP feature."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
 

Cons

"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."
"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."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"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."
"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"I think the implementation could be more streamlined."

"They're fairly inexpensive, but they're right in the ballpark of most of the other online products like that."
"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."

"The price of Microsoft Exchange Online Protection is reasonable."
"The solution falls on the higher or more expensive side of the spectrum."
