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

"Scalability is something that Cisco has always cared about."
"I would recommend this solution; it's reliable and scalable, with easy installation and integration."
"The solution is stable."
"The URL filtering is very good and you can create a group for customized URLs."
"In general, the features are all great. However, if I need to take hardware for ASA, because they need to upgrade to Firepower, we want to create rules. For that, most of the time we go to the command line. Right now Firepower is working really hard on the grid. You can apply all those rules to the grid. Even if you want to monitor the logs, for example, the activity will tell you which particular user has been blocked because of that rule. Firepower's monitoring interface is very good, because you can see each and every piece. ASA also had it, but there you needed to type the command and be under the server to see all that stuff. In Firepower you have the possibility to go directly to the firewall. The way the monitoring is displayed is also very nice. The feature I appreciate most in Firepower is actually the grid. The grid has worked very well."
"The most valuable feature of this solution is the filtering."
"If you compare it to other vendors, the technical support from Cisco is excellent."
"The whole solution is very good, and stable."
"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."
"The HTML file sandboxing is very good."
"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 performance and stability are great."
"This solution allows us to see anomalies, network traffic in our network, and zero-day threats."
"The environment is imported inside the sandbox and in this way, Trend Micro is the leader in the world's markets of sandbox solutions."
"The reporting is very good, providing detailed analysis in a short amount of time."
 

Cons

"Performance needs improvement."
"This solution needs to be more customizable."
"The pricing needs to be improved. We have lots of low-budget clients around us. Budget constraints are always a deterrent in our market."
"Integration with other components — even Cisco's own products — can be enhanced to improve administrative experience."
"I did not experience any pain points that required improvement. Maybe a couple of false-positives, but that's about it."
"The pricing needs to be improved."
"The implementation could be a bit easier."
"The cloud can be improved."
"The solution could be more secure."
"There were a few instances where legitimate traffic (WPAD) was flagged as C2 communication."
"The solution needs improvement in terms of pricing."
"Trend Micro Deep Discovery's technical support could be improved, and it could be made more active."
"Trend Micro can improve the pricing in general. There is nothing else they can add or improve in the solution."
"The stability of the solution could be improved. It should be 100% stable, but it's not there right now."
"The scalability is sometimes limited."
"The solution could be more stable and offer more security."
 

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."
"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."
"We have a three-year license for this solution."
"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 depend on the customers."
"The pricing is okay for some, and sometimes, some people find it expensive."
"The licensing cost is a bit pricey. We pay a yearly subscription."
"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."
"Compared to its competitors, Trend Micro Deep Discovery is a little expensive."
"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."
