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

"The most valuable feature of this solution is the filtering."
"The most valuable features of Cisco Sourcefire SNORT are the dashboard for monitoring events."
"The product is inexpensive compared to leading brands such as Palo Alto or Fortinet."
"With Cisco Sourcefire SNORT, we've been able to prevent and detect intrusion in our network and actually decrease our SLA (Service Level Agreement)."
"Cisco Sourcefire SNORT is easy to configure and the reporting is great. It's also very user-friendly."
"The solution is rather easy to use."
"The solution can be integrated with some network electors like Cisco Stealthwatch, Cisco ISE, and Active Directory to provide the client with authentication certificates."
"The most valuable feature is the ability to automatically learn the traffic in our environment, and change the merit recommendations based on that."
"The tool's most valuable feature is its collaboration with other products. Integrating with other security products was simple and easy."
"The HTML file sandboxing is very good."
"It is a very good solution. It is very light, and it is quite quick to figure out the problem in your network."
"We are trying this solution as a POC, it's a nice product and it has really helped limit the attacks."
"The most valuable feature is that the user can customize images of virtual machines in the sandbox functionality. The other vendors only use images that were created by the vendor but not the customer, end-user or partner. This helps to detect advanced threats and attacks."
"The product's initial setup phase was not difficult."
"The tool's stability and performance are good."
"The most valuable feature of Trend Micro Deep Discovery is its complete end-to-end visibility of threats."
 

Cons

"There are some bugs in this solution and troubleshooting them is complicated."
"To be frank, the product is not really stable, although they're working on that."
"With the next release, I would like to see some PBR, so that you can do the configuration with the features."
"The utopia is to see everything from one dashboard, but sometimes that's not very possible."
"To be frank, the product is not really stable, although they're working on that. Whenever I go to the technical community with an issue, they will usually say that it is not there yet, but the technical team are working on it. The issues are not insolvable. I think they should just keep working on the product to make sure that the product can become very stable. The technical support is great. I appreciate that. We have a lot of communities supporting Firepower now, so you can find help for whatever issue you have."
"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 don't think this solution is a time-based control system, because one cannot filter traffic based on time."
"I want to see a better dashboard for the product. The dashboard can be a bit modified or enhanced."
"I would like to see integration with third-party tools to improve the visibility of the dashboards."
"This solution could be improved with faster technical support and cheaper licensing prices."
"The scalability is sometimes limited."
"Trend Micro Deep Discovery's technical support could be improved, and it could be made more active."
"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."
"There are certain aspects of flexibility in the policies that should be added to Deep Discovery."
"The solution is not scalable as it is an agent product rather than a product designed for scalability."
"I am not aware if Trend Micro Deep Discovery provides any return on investment or cost reductions; it may not be beneficial in terms of finance."
 

Pricing and Cost Advice

"The cost is per port and can be expensive but it does include training and support for three years."
"We have a three-year license for this solution."
"If one is an extremely expensive product, and ten is cheap, I rate the tool's price as a five."
"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."
"Licensing for this solution is paid on a yearly basis."
"The price of the solution is lower compared to the competition."
"The tool’s licensing costs depend on the customers."
"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."
"Compared to its competitors, Trend Micro Deep Discovery is a little expensive."
"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 are yearly. There are no additional costs associated with the product."
"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."
"Overall, the price is good."
