IT Project Manager at Brilliant telecommunications
Helps us reduce phishing email attacks and has a user-friendly dashboard
It is the best product. It helps reduce spam and phishing attacks. It has user-friendly Real-Time Phishing Mitigation features for environmental protection. It primarily focuses on verifying security features like SPS (Sender Policy Framework) and Smart DKIM (DomainKeys Identified Mail). The DLP feature ensures that only emails meeting the required security standards pass through the secure gateway. The configuration and management of the policies and settings are easy to navigate. I rate it an eight out of ten.

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 helps reduce spam and phishing attacks."
"The solution is easier to manage than FortiMail. You can implement policies easily."
"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 most valuable feature of Microsoft Exchange Online Protection is the accidental release of information protection capabilities. Additionally, the solution is easy to use."
"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."
"It is scalable."
"The scalability is pretty good; it does what it is supposed to do."
"The email policy configuration options in Microsoft EOP are satisfactory."
"It has a really nice web-based administration console."
 

Cons

"Its pricing could be affordable."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."
"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."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"Our Exchange system is very locked down and secure, yet we still got hacked."
"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."
"Microsoft 365 Defender and EOP policies are stable with the proper license. However, with the basic policy, it's hard to say it's stable due to configuration limitations."
"The tool is not 100% stable."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
 

Pricing and Cost Advice

"Email Security Gateway's pricing is good."
"The pricing of the solution is reasonable."
"Apart from the license fee for the solution, there are no additional costs."
"The solution is expensive but is backed by Microsoft's reputation."
"The price of Microsoft Exchange Online Protection is reasonable."
"The solution is priced high and could be less expensive compared to other solutions."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"It's a high price."
"The tool's pricing is excellent."
