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.

Long-term threat visibility has reduced customer incidents and supports steady recurring revenue
The real-time visibility on network traffic provided by Trend Micro Deep Discovery is good, and my customer is satisfied. My customers have indeed utilized the Threat Intelligence Sharing feature of Trend Micro Deep Discovery. The impact of the Threat Intelligence Sharing feature on overall defense and security is positive. The benefit that Deep Discovery brings to our organization is that we get fewer calls from customers, allowing me to focus on other businesses, and we receive year-on-year revenue for renewals.

Pricing and Cost Advice

"Licensing for this solution is paid on a yearly basis."
"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."
"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."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
