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 feature is third-party integrations."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"The threat management feature includes policies and alerts that are valuable."
"The initial setup of Microsoft Exchange Online Protection was easy."
"It's all running in the backend, so it doesn't affect the app functionality."
"It is scalable."
"It is useful for local users and our company because we use Microsoft 365."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"The most valuable feature of Symantec Web Isolation is the user-friendliness of the solution."
 

Cons

"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 product's end-of-life cycle could be extended."
"It kind of has a heavy footprint in terms of an implementation footprint."
"The solution needs to improve its backup."
"Besides price, the main room for improvement includes the sandbox or something similar; the usability that solutions are focused on."
"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."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"Symantec Web Isolation could improve by reducing licensing costs."
 

Pricing and Cost Advice

"The solution falls on the higher or more expensive side of the spectrum."
"Apart from the license fee for the solution, there are no additional costs."
"The tool's pricing is excellent."
"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."
"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."
"Online Protection is fairly expensive."
"The solution is expensive but is backed by Microsoft's reputation."
"The product is expensive."
"The licensing cost of Symantec Web Isolation is high."
