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.

Stable product with valuable SSL inspection features
We use Zscaler Cloud IPS for threat protection, full SSL inspection, and data center scalability. It integrates with multiple products, including cloud firewalls, cloud sandboxing, Cloud Security Broker (CSB), and Data Loss Prevention (DLP). It helps us allow or block specific TCP or UDP ports…

Quotes from Members

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

Pros

"The tool's most valuable feature is threat detection, which is important because we have multiple layers not only in Cisco."
"The most valuable features of Cisco Sourcefire SNORT are the dashboard for monitoring events."
"The product is inexpensive compared to leading brands such as Palo Alto or Fortinet."
"It is quite an intelligent product."
"The whole solution is very good, and stable."
"The most valuable feature is the ability to automatically learn the traffic in our environment, and change the merit recommendations based on that."
"Cisco technical support is unbeatable. It offers a premium service every time."
"The solution can be integrated with some network electors like Cisco Stealthwatch, Cisco ISE, and Active Directory to provide the client with authentication certificates."
"The product's most valuable feature is complete SSL inspection."
"Cloud IPS integration is seamless, and it uses a Zero Trust model. It also simplifies overall user access management."
"The initial setup is straightforward and easy in comparison with other solutions."
"The initial setup process is easy."
"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."
 

Cons

"The customization of the rules can be simplified."
"The solution's approach to managing traffic blocking is confusing and impractical."
"There are problems setting up VPNs for some regions."
"The pricing needs to be improved. We have lots of low-budget clients around us. Budget constraints are always a deterrent in our market."
"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."
"Integration with other components — even Cisco's own products — can be enhanced to improve administrative experience."
"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."
"With the next release, I would like to see some PBR, so that you can do the configuration with the features."
"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."
"We encounter issues sharing IP addresses with other companies using the software."
"There is always room for improvement."
"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."
"When it comes to scalability, the IPsec could be improved."
 

Pricing and Cost Advice

"If one is an extremely expensive product, and ten is cheap, I rate the tool's price as a five."
"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 cost is per port and can be expensive but it does include training and support for three years."
"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."
"The software has become more expensive at present."
"The product is not affordable for small and medium enterprises."
