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.

Provides strong data protection with virtual patching and vulnerability assessments
I primarily use it to monitor database access, particularly in banking and similar environments. It ensures that IT personnel and others do not create unauthorized accounts or users. Collaboration security assists in tracking database access and alerts in case of suspicious activity One of the…

Quotes from Members

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

Pros

"I like the product's ZAP feature."

Cons

"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."
"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."
"The licensing can be on the expensive side, especially in the cloud space."
"It would be helpful for customers if Plan 1 features were included with EOP."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"The product's end-of-life cycle could be extended."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"The reporting needs a little bit of improvement."
"The custom tailoring is limited."
"The solution must provide features to scan QR codes for threats."
"The spam detection feature could be better."
"There is a need for improved integration with totally different products, such as a rapid server."
"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."
"I would like to see this solution become more flexible."
"The solution needs better support."
"I would rate them as a 1.5. The new hub created in India is not good."

"The cost is very high."
"The solution requires a license to be purchased for every user."
