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

"I like most of Cisco's features, like malware detection and URL filtering."
"The most valuable feature of this solution is the filtering."
"Cisco technical support is unbeatable. It offers a premium service every time."
"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."
"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 simplifies the configuration process by offering pre-defined base configurations, including security and connectivity settings."
"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 reliability, and this solution is better than Check Point."
"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."
"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 product's initial setup phase was not difficult."
"The performance and stability are great."
"Trend Micro has divided most of the solutions into different sectors, and if you want to go for the end-to-end solution, they are very much in a position to provide that because Trend Micro covers almost everything."
"There is no downtime or server vulnerability with this solution."
"We are trying this solution as a POC, it's a nice product and it has really helped limit the attacks."
"The tool's most valuable feature is its collaboration with other products. Integrating with other security products was simple and easy."
 

Cons

"Sometimes the solution will offer up false positives."
"I don't think this solution is a time-based control system, because one cannot filter traffic based on time."
"The cloud can be improved."
"The customization of the rules can be simplified."
"This solution needs to be more customizable."
"Cisco Sourcefire SNORT can scale, but if you have too much, you could fill up your log files, which I consider when discussing scalability."
"The implementation could be a bit easier."
"There are some bugs in this solution and troubleshooting them is complicated."
"The solution needs improvement in terms of pricing."
"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."
"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."
"There are certain aspects of flexibility in the policies that should be added to Deep Discovery."
"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 tool's configuration can be made easier."
"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."
"Scalability becomes an issue when managing a higher number of customers."
 

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."
"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."
"Licensing for this solution is paid on a yearly basis."
"We have a three-year license for this solution."
"The licensing cost is a bit pricey. We pay a yearly subscription."
"The tool’s licensing costs depend on the customers."
"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."
"Overall, the price is good."
"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 price of the solution is lower compared to the competition."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
