Featured Reviews

Vladimir Alexandrov - PeerSpot reviewer
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clients can identify forgotten or unmanaged network segments, thereby mitigating unexpected network actions such as outdated antivirus software operations.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.
Atdhe Zyhranaj - PeerSpot reviewer
It allows for a separation between cloud applications and URL filtering
We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve.

Quotes from Members

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

Pros

"The tool's stability and performance are good."
"The most valuable features are the protection and that it is fast."
"One of the most valuable features is the performance, since, so far, we have not faced any issues with Deep Discovery."
"Sandboxing gives us a chance to identify malicious behavior, especially for unknown vulnerabilities, although it's rarely needed as a last resort after all other security measures have failed."
"Initial setup is easy. It can be done by yourself."
"As a security product, managing threats is crucial for my clients."
"Deep Discovery is scalable and compatible with other products. It's crucial to have that compatibility because it's an integral part of our security solution. It integrates smoothly. The interface is user-friendly, so administration is simple."
"There is no downtime or server vulnerability with this solution."
"The product's most valuable feature is complete SSL inspection."
"The best feature is that Zscaler allows for a separation between cloud applications and URL filtering. For example, under the cloud application segment, I can bypass Microsoft Office 365 without the need to add URLs manually. It's one click, so that's handy."
"The initial setup process is easy."
"The initial setup is straightforward and easy in comparison with other solutions."
"Cloud IPS integration is seamless, and it uses a Zero Trust model. It also simplifies overall user access management."
 

Cons

"This solution could be improved with faster technical support and cheaper licensing prices."
"The solution could be more secure."
"The solution could be more stable and offer more security."
"There are certain aspects of flexibility in the policies that should be added to Deep Discovery."
"Deep Discovery is easy to manage, but there is still room for improvement on the administration and operations side. Competing products have a cleaner interface that makes it easier to manage their products. Trend Micro offers a lot of features in one product suite, but it can be unwieldy for the customer to manage all that with a single interface."
"Trend Micro Deep Discovery is a very expensive solution, making it very hard to sell."
"The scalability is sometimes limited."
"I would like to see integration with third-party tools to improve the visibility of the dashboards."
"They have given limited free access for a year. Instead, they should increase the file size and give limited free access for around two months. It will allow engineers to evaluate the product."
"When it comes to scalability, the IPsec could be improved."
"We encounter issues sharing IP addresses with other companies using the software."
"There is always room for improvement."
"We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve."
 

Pricing and Cost Advice

"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."
"The tool’s licensing costs depend on the customers."
"Compared to its competitors, Trend Micro Deep Discovery is a little expensive."
"The tool's licensing costs are yearly. There are no additional costs associated with the product."
"The price of the solution is lower compared to the competition."
"Overall, the price is good."
"The licensing cost is a bit pricey. We pay a yearly subscription."
"Its price is fine, but Trend Micro can improve the pricing in general. It is a hardware solution. It is based on the number of nodes, and according to the number of nodes, clients decide which box they should acquire. They have to renew their license every year. It is subscription-based."
"Zscaler has so far been solely responsible for all the sales we have done with it, so it would be more suited than us to address any issues concerning the pricing."
"The product is not affordable for small and medium enterprises."
"The software has become more expensive at present."
