Featured Reviews

Jose Vargas - PeerSpot reviewer
Agente De Servicios Técnicos at a computer software company with 11-50 employees
Has improved threat detection workflows and supports seamless customer monitoring
The best features Trellix Network Detection and Response offers include very good threat detection, and I believe that it is one of the best XDR tools. For example, ePO and XDR components are very comfortable and similar to many other tools for this type of monitoring, and I have received very good feedback for this tool. What makes Trellix Network Detection and Response stand out for me compared to other tools is the way you can detect threats. It is very easy and comfortable to use, and the detection shows clearly on the screen, which is very easy to understand. Regarding the features, I think that the integration with other platforms is very comfortable with the customer because we can integrate it with any switch or firewall, and it is comfortable to add this tool. Trellix Network Detection and Response has positively impacted my organization as I have improved my knowledge about detection and response. I have already used some other tools such as CrowdStrike and Umbrella, but Trellix is one of the best that I have tested. I believe that for my organization, Trellix has helped a lot with detection and supported our customers effectively. Trellix Network Detection and Response is a great tool that integrates with a lot of security tools such as Palo Alto, which is a good firewall. If you have these types of tools, your organization would benefit greatly.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.
