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clients can identify forgotten or unmanaged network segments, thereby mitigating unexpected network actions such as outdated antivirus software operations.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.

Quotes from Members

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

Pros

"It is a very good solution. It is very light, and it is quite quick to figure out the problem in your network."
"Trend Micro Deep Discovery is a very specific product for threat intelligence with smart protection."
"Initial setup is easy. It can be done by yourself."
"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."
"The most valuable features are monitoring for advanced persistent threats, the system runs in a sandbox allowing for effective zero-day exploits management, and the Inspector has a built-in sandbox."
"There is no downtime or server vulnerability with this solution."
"I like the sales operations testing. and support."
"The reporting is very good, providing detailed analysis in a short amount of time."
"Cloud IPS integration is seamless, and it uses a Zero Trust model. It also simplifies overall user access management."
"The initial setup process is easy."
"The initial setup is straightforward and easy in comparison with other solutions."
"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 product's most valuable feature is complete SSL inspection."
 

Cons

"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."
"Scalability becomes an issue when managing a higher number of customers."
"The solution needs improvement in terms of pricing."
"The tool's configuration can be made easier."
"Additionally, better scanning capabilities for third-party applications would ensure comprehensive security without the need for exclusions."
"The price range is a little high."
"The main issue is its high cost."
"There are certain aspects of flexibility in the policies that should be added to Deep Discovery."
"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."
"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."
 

Pricing and Cost Advice

"Overall, the price is good."
"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."
"The tool's licensing costs are yearly. There are no additional costs associated with the product."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
"The tool’s licensing costs depend on the customers."
"The price of the solution is lower compared to the competition."
"Compared to its competitors, Trend Micro Deep Discovery is a little expensive."
"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."
"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 software has become more expensive at present."
"The product is not affordable for small and medium enterprises."
