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."
"It is quite an intelligent product."
"The tool's most valuable feature is threat detection, which is important because we have multiple layers not only in Cisco."
"With Cisco Sourcefire SNORT, we've been able to prevent and detect intrusion in our network and actually decrease our SLA (Service Level Agreement)."
"The most valuable feature is the ability to automatically learn the traffic in our environment, and change the merit recommendations based on that."
"The most valuable feature is the visibility that we have across the virtual environment."
"The whole solution is very good, and stable."
"It has a huge rate of protection. It's has a low level of positives and a huge rate of threat protection. It's easy to deploy and easy to implement. It has an incredible price rate compared to similar solutions."
"It is a very good solution. It is very light, and it is quite quick to figure out the problem in your network."
"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 HTML file sandboxing is very good."
"The solution has extension-based features that help it to analyze the environment. The environment can have different platforms like Windows, Linux, and Mac. The tool will give a report which can confirm the analysis of the issues. You can also get clear information on threats or suspicious files."
"The real-time visibility on network traffic provided by Trend Micro Deep Discovery is good, and my customer is satisfied."
"The platform provides all essential features for discovery and administration."
"As a security product, managing threats is crucial for my clients."
"We are trying this solution as a POC, it's a nice product and it has really helped limit the attacks."
 

Cons

"I would like to have analytics included in the suite."
"I did not experience any pain points that required improvement. Maybe a couple of false-positives, but that's about it."
"The solution's approach to managing traffic blocking is confusing and impractical."
"Performance needs improvement."
"I don't think this solution is a time-based control system, because one cannot filter traffic based on time."
"Integration with other components — even Cisco's own products — can be enhanced to improve administrative experience."
"The main dashboard of Cisco Sourcefire SNORT could improve."
"The price of this solution could be improved."
"The solution could be more secure."
"The price range is a little high."
"The scalability is sometimes limited."
"There are certain aspects of flexibility in the policies that should be added to Deep Discovery."
"I would like to see integration with third-party tools to improve the visibility of the dashboards."
"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."
"This solution could be improved with faster technical support and cheaper licensing prices."
"The solution should support multiple platforms in Windows, Linux, and Mac. Customers can have different software types. The virtual environment should be able to install and analyze them. The tool also gives only a minimum level of extension support. It may not be able to extract files and give details about them. I would also like to see third-party product integration in the tool. The solution's current integration is only with Trend Micro products only."
 

Pricing and Cost Advice

"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."
"If one is an extremely expensive product, and ten is cheap, I rate the tool's price as a five."
"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."
"The pricing is okay for some, and sometimes, some people find it expensive."
"The price of the solution is lower compared to the competition."
"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, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
"Overall, the price is good."
"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."
