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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We primarily use this solution as an intrusion prevention system for external firewalls and deploy the solution on-premises."
"Scalability is something that Cisco has always cared about."
"Solid intrusion detection and prevention that scales easily in very large environments."
"It simplifies the configuration process by offering pre-defined base configurations, including security and connectivity settings."
"I would recommend this solution; it's reliable and scalable, with easy installation and integration."
"There are a lot of features that I really appreciate with Firepower, which is why I advise most of my customers to go with Firepower."
"The solution is rather easy to use."
"The tool's most valuable feature is threat detection, which is important because we have multiple layers not only in Cisco."
"The initial setup process is easy."
"The initial setup is straightforward and easy in comparison with other solutions."
"The best feature is that Zscaler allows for a separation between cloud applications and URL filtering. For example, under the cloud application segment, I can bypass Microsoft Office 365 without the need to add URLs manually. It's one click, so that's handy."
"The product's most valuable feature is complete SSL inspection."
"Cloud IPS integration is seamless, and it uses a Zero Trust model, and it also simplifies overall user access management."
 

Cons

"Sometimes the solution will offer up false positives."
"There are problems setting up VPNs for some regions."
"If the price is brought down then everybody will be happy."
"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 cloud can be improved."
"I want to see a better dashboard for the product. The dashboard can be a bit modified or enhanced."
"This is a good solution, but some others may have some advantages."
"The main dashboard of Cisco Sourcefire SNORT could improve."
"We encounter issues sharing IP addresses with other companies using the software."
"They have given limited free access for a year. Instead, they should increase the file size and give limited free access for around two months. It will allow engineers to evaluate the product."
"We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve."
"There is always room for improvement."
"When it comes to scalability, the IPsec could be improved."
 

Pricing and Cost Advice

"We have a three-year license for this solution."
"If one is an extremely expensive product, and ten is cheap, I rate the tool's price as a five."
"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."
"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 product is not affordable for small and medium enterprises."
"The software has become more expensive at present."
"Zscaler has so far been solely responsible for all the sales we have done with it, so it would be more suited than us to address any issues concerning the pricing."
