Beneficial AI detection, helpful support, but modern UI needed
The initial setup of the Hillstone I-Series Server Breach Detection System requires a bunch of steps starting with installing the hardware and setting it up. However, most of the setup is done by the vendor. I rate the initial setup of the Hillstone I-Series Server Breach Detection System an eight out of ten. The vendor provides free training in the software provided.

Has improved email security through advanced filtration and timely threat detection
I work with Trend Micro Apex One. I have used the Deep Discovery's Sandbox analysis feature, and we utilize another appliance known as Deep Discovery Analyzer, abbreviated as DDA. This tool makes analysis for URLs and attachments contained in inbound emails, so whenever we receive an email with a URL or attachment, it will be analyzed by Trend Micro Deep Discovery Analyzer. In evaluating Deep Discovery's real-time visibility on network traffic, it is important to note that we applied our Deep Discovery Analyzer for Trend Micro to conduct sandboxing specifically for email channels only, and we do not utilize it for network channels. For network channel sandboxing, we use a solution called FortiAnalyzer, which belongs to another team called network security. I assess Deep Discovery's effectiveness in identifying sophisticated attack patterns by looking at how it handles high traffic loads, and how effectively it can use its instances and images to analyze numerous URLs and attachments simultaneously. Additionally, I evaluate its ability to maintain round-robin or load balancing across different analyses without leaving samples queued for analysis. The performance is critical when the product updates for signatures are up-to-date, as this aids in the detection and classification of URLs and attachments without delay in the analysis process. On a scale of one to ten, I rate Trend Micro Deep Discovery a nine.

Quotes from Members

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

Pros

"The most valuable features of the Hillstone I-Series Server Breach Detection System are the AI detection and monitoring of common threats."
"One or two people can maintain and support the solution. The maintenance is not difficult."
"One or two people can maintain and support the solution. The maintenance is not difficult."
"I like the sales operations testing. and support."
"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."
"The solution is extremely easy to install; it's not overly complex or difficult to set it up, and you can get it up and running pretty quickly."
"All in all, the variety of products provided by Trend Micro will give you a huge step up into checking and defending yourself from any threats."
"The environment is imported inside the sandbox and in this way, Trend Micro is the leader in the world's markets of sandbox solutions."
"We are trying this solution as a POC, it's a nice product and it has really helped limit the attacks."
"Trend Micro Deep Discovery Email Inspector includes its ability to perform mail detection and mail filtration against various email attacks such as phishing and spam, serving as an email gateway for both inbound and outbound traffic."
"The product's initial setup phase was not difficult."
 

Cons

"The UI dashboard view needs to be improved because it is ugly. If it was more modern it would be better. Additionally, better integration with other databases would be good."
"Hillstone I-Series Server Breach Detection System can improve by having more anti-spam features that will hopefully eliminate all of the other threats."
"Hillstone I-Series Server Breach Detection System can improve by having more anti-spam features that will hopefully eliminate all of the other threats."
"Sometimes there needs to be a stability test done. We did tests and checked up to around 20 or 25 samples; out of those tests, two missed and were later detected on the endpoint, so it is not completely stable and it misses things."
"Trend Micro can improve the pricing in general."
"The solution is not scalable as it is an agent product rather than a product designed for scalability."
"All issues we faced related to false positives regarding many hashes and URLs specifically for mail gateway and sandboxing, which led us to open a threat ticket with Trend Micro support for validation."
"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."
"There were a few instances where legitimate traffic (WPAD) was flagged as C2 communication."
"Trend Micro can improve the pricing in general. There is nothing else they can add or improve in the solution."
"I would like the ability to analyze all files in our internal network, at the same time on different operating systems. Not just three of them, but as many as possible."
