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 URL filtering is very good and you can create a group for customized URLs."
"It is quite an intelligent product."
"Solid intrusion detection and prevention that scales easily in very large environments."
"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 product is inexpensive compared to leading brands such as Palo Alto or Fortinet."
"The most valuable feature of this solution is the filtering."
"Cisco Sourcefire SNORT is easy to configure and the reporting is great. It's also very user-friendly."
"One of the most valuable features is the performance, since, so far, we have not faced any issues with Deep Discovery."
"The platform provides all essential features for discovery and administration."
"The real-time visibility on network traffic provided by Trend Micro Deep Discovery is good, and my customer is satisfied."
"The most valuable feature of Trend Micro Deep Discovery is its complete end-to-end visibility of threats."
"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."
"Initial setup is easy. It can be done by yourself."
"Fire Eye is incredibly expensive, and requires multiple appliances which together, scan far less protocols than DDi."
"The performance and stability are great, and we've been able to maximize the bandwidth allocated to us while Trend Micro has been very helpful in guiding us on what we need and where to place all the missing sniffing ports."
 

Cons

"The pricing needs to be improved."
"Integration with other components — even Cisco's own products — can be enhanced to improve administrative experience."
"Integration with other components — even Cisco's own products — can be enhanced to improve administrative experience."
"With the next release, I would like to see some PBR, so that you can do the configuration with the features."
"If the price is brought down then everybody will be happy."
"The pricing needs to be improved. We have lots of low-budget clients around us. Budget constraints are always a deterrent in our market."
"To be frank, the product is not really stable, although they're working on that."
"The implementation could be a bit easier."
"Trend Micro can improve the pricing in general. There is nothing else they can add or improve in the solution."
"The main issue is its high cost."
"I would like to see them create a rule where it could integrate with the network and start mitigating with auto-detection."
"The product's security features need enhancement."
"The price range is a little high."
"The solution could be more stable and offer more security."
"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."
"This solution could be improved with faster technical support and cheaper licensing prices."
 

Pricing and Cost Advice

"Licensing for this solution is paid on a yearly basis."
"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."
"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."
"The pricing is okay for some, and sometimes, some people find it expensive."
"The tool’s licensing costs depend on the customers."
"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."
"The tool's licensing costs are yearly. There are no additional costs associated with the product."
"The licensing cost is a bit pricey. We pay a yearly subscription."
