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

"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"The product protects against malware."
"The product's most valuable feature is third-party integrations."
"The scalability is pretty good; it does what it is supposed to do."
"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
"The initial setup is just a standard process."
"The most valuable feature of Symantec Web Isolation is the user-friendliness of the solution."
 

Cons

"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
"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."
"We would like the solution to have more in-built intelligence in the way that it reviews potential security risks, rather than our team constantly having to update the policies."
"Microsoft has some training portals, but more could be developed."
"The solution lacks to elaborate on its spam policies."
"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 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."
"Symantec Web Isolation could improve by reducing licensing costs."
 

Pricing and Cost Advice

"The solution is priced high and could be less expensive compared to other solutions."
"The solution is expensive but is backed by Microsoft's reputation."
"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."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"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."
"Apart from the license fee for the solution, there are no additional costs."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"The solution should reduce the cost."
"The licensing cost of Symantec Web Isolation is high."
