Featured Reviews

Jack Poon - PeerSpot reviewer
Offers ease of setup and good documentation
When it comes to the product's deployment phase, we have a lot of vendor support. We have a lot of skills here in Hong Kong. Our company doesn't find any problem deploying Cisco solutions. The solution is deployed on an on-premises version. Speaking about the time required to deploy the solution, I would say that we have quite a lot of previous experience with deploying Cisco products. We have our company's standard design document, which we need to follow. We have a standard testing procedure for all those features. We just take out some appropriate parts and then compile them into one document for an individual project. It is actually quite easy for us to do the documentation, so it just takes one or two hours, and we can do the implementation because all the materials and testing procedures are already in our company standard documents, so it is not that difficult for us.

Enhanced threat detection through superior sandboxing capabilities with competitive pricing
With Trend Micro Deep Discovery, our enterprise clients can identify forgotten or unmanaged network segments, thereby mitigating unexpected network actions such as outdated antivirus software operations. When under attack, such as with ransomware, it allows us to identify the attack vector and disable it. It also assists in security audits required to prove certain network security measures.

Cons

"With the next release, I would like to see some PBR, so that you can do the configuration with the features."
"I don't think this solution is a time-based control system, because one cannot filter traffic based on time."
"While the alerts they offer are good, it could improve it in the sense that they should be more detailed to make the alerts more useful to us in general. Sometimes the solution will offer up false positives. Due to the fact that the alerts aren't detailed, we have to go dig around to see why is it being blocked. The solution would be infinitely better if there was just a bit more detail in the alert information and logging we receive."

Why don't you propose something like FortiGate, Check Point, or Palo Alto?" Cisco device are expensive compared to other devices."
