PC
Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.
Amber Worth - PeerSpot reviewer
Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
"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."
"You can use the product to create special accounts."
"It is an easy solution."
"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 product's most valuable feature is third-party integrations."
"It has a really nice web-based administration console."
"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."
"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."
 

Cons

"Malware needs improvement."
"FTP server and TRUST Manager functionality."
"Performance and speed should continue to be improved."
"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 solution needs to improve its backup."
"The product's end-of-life cycle could be extended."
"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."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
"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."
"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
 

Pricing and Cost Advice

Information not available
"The pricing of the solution is reasonable."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The solution is expensive but is backed by Microsoft's reputation."
"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."
"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'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."
"It is a low-price solution."
