Has offered reliable threat protection and detailed network insights but could expand features beyond existing capabilities
The best features of Trellix Intrusion Prevention System include advanced ATP (Advanced Threat Protection), which uses signatures, behavior analysis, and machine learning to stop zero-day exploits and malware advanced persistent threats (APTs). They track and collect data from APTs, which allows them to track malicious files entering the environment. The system offers inline prevention and real-time automatic blocking of malicious packets before they reach the network. It integrates with the Trellix ecosystem and provides application visibility and control. The solution provides deep insight into network traffic, applications, and protocols for better information. All packets coming through the application are analyzed and reported. They share intelligence updates regularly to protect from different malicious files and sector-specific threats. It supports both on-premise and cloud environments.

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 most valuable features of the solution stem from the fact that it is a good product for dealing with DDoS attacks and for the inspection of network traffic."
"The product is worth the investment."
"The threat intelligence updates are very accurate."
"Overall the solution is very good. It offers great protection and gives us a good overview of what is on the network."
"It has a lot of functions, such as firewall. We are administrators, and we create some rules to protect our network. We also monitor the traffic in and out and have disk encryption on-premises. When we detect malware, we scan for the virus on the PC. We can then delete or block the malware."
"The best feature of the Trellix Intrusion Prevention System is the rules that Trellix provides, I think that's the best value from IPS."
"There's a good dashboard you can drill down into. It helps you easily locate intrusions and the source of attacks."
"The best features of Trellix Intrusion Prevention System include advanced ATP (Advanced Threat Protection), which uses signatures, behavior analysis, and machine learning to stop zero-day exploits and malware advanced persistent threats (APTs)."
"The initial setup is straightforward and easy in comparison with other solutions."
"Cloud IPS integration is seamless, and it uses a Zero Trust model. It also simplifies overall user access management."
"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 initial setup process is easy."
"The product's most valuable feature is complete SSL inspection."
 

Cons

"Integration with Global Thereat Intelligence could be better. Also, I think management solutions are end of life now at McAfee. Network threat analyzer may be used for endpoint quarantines. Integration between these sides, as well as endpoint APO, will help you quarantine the risky endpoints."
"The platform’s GUI could be the latest."
"The management console needs to be less complex and easier to navigate."
"The Network Security Managers could be more stable, agile, and work faster. When it comes to instability, there is room for improvement."
"The pricing could be improved."
"Some of the documentation is not as straightforward as it could be."
"The technical support has room for improvement."
"The area of concern where the tool needs improvement is how the product prompts users at a network level that helps prevent any wireless network attacks through alerts and notifications."
"When it comes to scalability, the IPsec could be improved."
"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."
"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 encounter issues sharing IP addresses with other companies using the software."
"There is always room for improvement."
 

Pricing and Cost Advice

"The tool is competitively priced."
"I rate the product’s pricing an eight out of ten."
"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."
