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.

Quotes from Members

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

Pros

"It provides security to both on-premises and Azure infrastructures."
"We can migrate seamlessly without any disruptions to our operations."

"It is an easy solution."
"The initial setup was easy. The configuration process is very straightforward."
"It's definitely scalable."
"We have had very good results from the use of FireEye Email Security. We are very comfortable with this technology, but I don't know if it's necessary to move into the cloud, we will check other technologies and study them. Additionally, the solution has good integration."
"The solution's most valuable feature is its simplicity. It's very user-friendly."
"The product helps reduce the number of malicious emails reaching the user's inbox."
"Before installing, consider potential challenges with system performance, especially when integrating multiple tools, which could slow down performance."
"FireEye Email Security helps us prevent spam and phishing emails and all other business-compromised email attacks."
"What I find most valuable with the solution is that it can integrate with cloud solutions, such as Google and Microsoft. Additionally, the solution is easy to use."
"I like FireEye's filtering, spam digests, and its advanced threat review of email flow. It also has a broad range of riskware rules you can deploy."
"The auto-remediation feature is valuable."
 

Cons

"It doesn't protect against everything. We do need protection for, for example, endpoints."
"The tool's classification for bulk email is cumbersome."
"When you're using a Microsoft product solution, you can scale it, but if you're not, there are limitations."
"Performance and speed should continue to be improved."
"Microsoft has some training portals, but more could be developed."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"The solution lacks to elaborate on its spam policies."
"The solution must provide features to scan QR codes for threats."
"The reporting aspect of the solution needs improvement."
"If they want to be the primary or best solution, they need to have better email management features."

"The spam detection feature could be better."
"I would like to see this solution become more flexible."
"I would like the solution to be able to automatically quarantine the malicious emails before getting to the user's mailbox and continue with regular email operations. This could result in the user clicking the email before the purge operation is completed."
"The solution needs better support."
 

Pricing and Cost Advice

"Apart from the license fee for the solution, there are no additional costs."
"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."
"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."
"It's a high price."
"The tool's pricing is excellent."
"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."
"I rate the product price as nine out of ten, where ten is the most expensive, and one is the cheapest. There is no need to pay any extra charges apart from the licensing costs."
"The solution requires a license to be purchased for every user."
"The licensing is on a yearly basis."
"The cost is very high."
