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.

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

"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"Go for it! I think it's an excellent product with great technical support."
"We use a few features for web proxy, and another feature is the email content filter and malware for our internal policy in the email content."
"The product's most valuable feature is third-party integrations."
"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."
"It is useful for local users and our company because we use Microsoft 365."
"The solution's stability is very, very good. I didn't face any problems in the last year."
"It has a really nice web-based administration console."
"It is scalable."
"We like the holding facility that is available for potentially suspicious URLs, which allows a real-time review to be performed before the email reaches a user's inbox."

Cons

"Malware needs improvement."
"FTP server and TRUST Manager functionality."
"I am not satisfied with Clearswift because of the lack of customer support."

"Our company faces difficulty with Microsoft Exchange Online Protection (EOP) because it's too big, clunky, and difficult for a small client to implement quickly and easily."
"The reporting needs a little bit of improvement."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."
