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

Pros

"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 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 most valuable feature of this solution is the filtering."
"The most valuable feature is the visibility that we have across the virtual environment."
"Users have access to intelligent security automation as one of the features, which can easily automate your event impact assessment so your IPS policy tuning can be done as well as your network behavior analysis, and you can do real-time contextual awareness with correlation of events created on your applications, user devices, operating systems, or vulnerabilities, with all of this real-time data captured including your apps and port scans."
"With Cisco Sourcefire SNORT, we've been able to prevent and detect intrusion in our network and actually decrease our SLA (Service Level Agreement)."
"This solution makes life a lot easier as there are fewer man-hours required and we no longer need too many resources to manage it."
"If you compare it to other vendors, the technical support from Cisco is excellent."
"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."
"Trend Micro Deep Discovery is a very specific product for threat intelligence with smart protection."
"The reporting is very good, providing detailed analysis in a short amount of time."
"The HTML file sandboxing is very good."
"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."
"One of the most valuable features is the performance, since, so far, we have not faced any issues with Deep Discovery."
"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."
"As a security product, managing threats is crucial for my clients."
 

Cons

"I would like to have analytics included in the suite."
"Cisco Sourcefire SNORT can scale, but if you have too much, you could fill up your log files, which I consider when discussing scalability."
"There are problems setting up VPNs for some regions."
"The main dashboard of Cisco Sourcefire SNORT could improve."
"The utopia is to see everything from one dashboard, but sometimes that's not very possible."
"Sometimes the solution will offer up false positives."
"This solution needs to be more customizable."
"Integration with other components — even Cisco's own products — can be enhanced to improve administrative experience."
"The stability of the solution could be improved. It should be 100% stable, but it's not there right now."
"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."
"The scalability is sometimes limited."
"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."
"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."
"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."
 

Pricing and Cost Advice

"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."
"We have a three-year license for this solution."
"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."
"The cost is per port and can be expensive but it does include training and support for three years."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
"The price of the solution is lower compared to the competition."
"The licensing cost is a bit pricey. We pay a yearly subscription."
"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 tool’s licensing costs depend on the customers."
"The pricing is okay for some, and sometimes, some people find it expensive."
