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.
BernardLugalia - PeerSpot reviewer
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

"The initial setup is just a standard process."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"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."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"The solution's stability is very, very good. I didn't face any problems in the last year."
"It provides security to both on-premises and Azure infrastructures."
"We like the holding facility that is available for potentially suspicious URL's. This allows a real-time review to be performed before the email reaches a users inbox."
"One of the valuable features of the product stems from the fact that it is easy to implement the tool in our environment."
"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."
"FireEye is good for malware depicting and security."
"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."
"Before installing, consider potential challenges with system performance, especially when integrating multiple tools, which could slow down performance."
"The initial setup is simple."
"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."
"Trellix Collaboration Security is valued for being a stable and comprehensive solution that fulfills customer needs."
 

Cons

"The solution lacks to elaborate on its spam policies."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"When you're using a Microsoft product solution, you can scale it, but if you're not, there are limitations."
"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."
"It would be helpful for customers if Plan 1 features were included with EOP."
"The solution needs to improve its backup."
"The product's end-of-life cycle could be extended."
"I would like to see this solution become more flexible."
"The solution must provide features to scan QR codes for threats."
"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 custom tailoring is limited."
"The spam detection feature could be better."
"FireEye needs single sign-on. They say it's on their roadmap. They should also implement support for Microsoft Authenticator app for 2FA."
"Sometimes, integration can be challenging, impacting its stability, which is why I rate it a five out of ten."
"I would rate them as a 1.5. The new hub created in India is not good."
 

Pricing and Cost Advice

"It is a low-price solution."
"The product is bundled with Microsoft 365."
"The product's pricing is competitive for the US market."
"The solution falls on the higher or more expensive side of the spectrum."
"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."
"Online Protection is fairly 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."
"The solution should reduce the cost."
"The solution requires a license to be purchased for every user."
"The licensing is on a yearly basis."
"The cost is very high."
"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."
