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 Sourcefire SNORT is easy to configure and the reporting is great. It's also very user-friendly."

"I like most of Cisco's features, like malware detection and URL filtering."

"The URL filtering is very good and you can create a group for customized URLs."

"The tool's most valuable feature is threat detection, which is important because we have multiple layers not only in Cisco."

"The product is inexpensive compared to leading brands such as Palo Alto or Fortinet."

"The most valuable feature is the visibility that we have across the virtual environment."

"It simplifies the configuration process by offering pre-defined base configurations, including security and connectivity settings."

"The solution can be integrated with some network electors like Cisco Stealthwatch, Cisco ISE, and Active Directory to provide the client with authentication certificates."

More Cisco Sourcefire SNORT pros

"It is a very good solution. It is very light, and it is quite quick to figure out the problem in your network."

"Initial setup is easy. It can be done by yourself."

"The most valuable feature is that the user can customize images of virtual machines in the sandbox functionality. The other vendors only use images that were created by the vendor but not the customer, end-user or partner. This helps to detect advanced threats and attacks."

"Trend Micro Deep Discovery Email Inspector includes its ability to perform mail detection and mail filtration against various email attacks such as phishing and spam, serving as an email gateway for both inbound and outbound traffic."

"The most valuable feature of Trend Micro Deep Discovery is its complete end-to-end visibility of threats."

"One of the most valuable features is the performance, since, so far, we have not faced any issues with Deep Discovery."

"The performance and stability are great."

"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."

Cons

"The implementation could be a bit easier."

"I would like to have analytics included in the suite."

"The cloud can be improved."

"I want to see a better dashboard for the product. The dashboard can be a bit modified or enhanced."

"Integration with other components — even Cisco's own products — can be enhanced to improve administrative experience."

"While the alerts they offer are good, it could improve it in the sense that they should be more detailed to make the alerts more useful to us in general. Sometimes the solution will offer up false positives. Due to the fact that the alerts aren't detailed, we have to go dig around to see why is it being blocked. The solution would be infinitely better if there was just a bit more detail in the alert information and logging we receive."

"The initial setup is a little difficult compared to other products in the market. It depends on the environment. If we are doing any migration, it might take months in a brown-field environment."

"We are unhappy with technical support for this solution, and it is not as professional as what we typically expect from Cisco."

More Cisco Sourcefire SNORT cons

"I would like to see integration with third-party tools to improve the visibility of the dashboards."

"The product's scalability feature needs to be improved, as it is an area in the product with certain shortcomings."

"The solution could be more secure."

"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 solution needs to be able to integrate better with third-party infrastructure."

"Trend Micro Deep Discovery's technical support could be improved, and it could be made more active."

"The product's security features need enhancement."

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."

"We have a three-year license for this solution."

"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."

"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."

"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."

"Overall, the price is good."

"Compared to its competitors, Trend Micro Deep Discovery is a little expensive."

"The tool’s licensing costs depend on the customers."

"The licensing cost is a bit pricey. We pay a yearly subscription."
