Logging and customizable rules have helped improve threat monitoring and detection
The logging is mainly what I consider one of the best features with Cisco Sourcefire SNORT. Being able to log and store it in a file allows you to push it to a centralized repository. The logging and reporting help improve incident response. You should always be logging threats, any sort of misconfiguration, and anything that could be an issue. It's important to at least log and monitor it. The basic rules provide a good baseline in assessing Cisco Sourcefire SNORT's ability in providing real-time analytics for threat detection, but as a professional, you should look to constantly modify that baseline. They provide extensive customizability so you can define your own rules. The customizability allows it to be adaptable in protecting against diverse network threats to the constant change.

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

"Cisco technical support is unbeatable. It offers a premium service every time."
"I like most of Cisco's features, like malware detection and URL filtering."
"The most valuable feature of this solution is the filtering."
"The solution is rather easy to use."
"The most valuable feature is reliability, and this solution is better than Check Point."
"The URL filtering is very good and you can create a group for customized URLs."
"There are a lot of features that I really appreciate with Firepower, which is why I advise most of my customers to go with Firepower."
"Solid intrusion detection and prevention that scales easily in very large environments."
"The tool's most valuable feature is its collaboration with other products. Integrating with other security products was simple and easy."
"The environment is imported inside the sandbox and in this way, Trend Micro is the leader in the world's markets of sandbox solutions."
"Initial setup is easy. It can be done by yourself."
"The product is very easy to install."
"The performance and stability are great, and we've been able to maximize the bandwidth allocated to us while Trend Micro has been very helpful in guiding us on what we need and where to place all the missing sniffing ports."
"Generally speaking, it just gives us a broad understanding of exactly what kind of threats occur. The submission point, analyzing point, and virtualization are within the environment that it supports. It helped us to improve our security levels and protect our internal network from any threats outside."
"The reporting is very good, providing detailed analysis in a short amount of time."
"The performance and stability are great."
 

Cons

"Cisco Sourcefire SNORT can scale, but if you have too much, you could fill up your log files, which I consider when discussing scalability."
"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."
"I would like to have analytics included in the suite."
"The pricing needs to be improved. We have lots of low-budget clients around us. Budget constraints are always a deterrent in our market."
"The price of this solution could be improved."
"This is a good solution, but some others may have some advantages."
"The main dashboard of Cisco Sourcefire SNORT could improve."
"There are some bugs in this solution and troubleshooting them is complicated."
"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."
"The solution is not scalable as it is an agent product rather than a product designed for scalability."
"There were a few instances where legitimate traffic (WPAD) was flagged as C2 communication."
"This solution could be improved with faster technical support and cheaper licensing prices."
"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."
"The product's scalability feature needs to be improved, as it is an area in the product with certain shortcomings."
"The product's security features need enhancement."
"I would like to see them create a rule where It could integrate with the network and start mitigating with auto-detection."
 

Pricing and Cost Advice

"We have a three-year license for this solution."
"Licensing for this solution is paid on a yearly basis."
"The cost is per port and can be expensive but it does include training and support for three years."
"I don't know the exact amount, but most of the time when I go to a company with a proposition, they will say, "This thing that you are selling is good, but it's expensive. Why don't you propose something like FortiGate, Check Point, or Palo Alto?" Cisco device are expensive compared to other devices."
"If one is an extremely expensive product, and ten is cheap, I rate the tool's price as a five."
"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."
"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."
"The licensing cost is a bit pricey. We pay a yearly subscription."
"Compared to its competitors, Trend Micro Deep Discovery is a little expensive."
"The price of the solution is lower compared to the competition."
"The tool’s licensing costs depend on the customers."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
