Featured Reviews

Twinkle Solanki - PeerSpot reviewer
Business development executive at Digitaltrack solution Pvt Ltd
Continuous network insight has improved early threat detection and streamlined investigations
Overall, we have a positive experience with Trellix Network Detection and Response, but like any enterprise security solution, there are areas where it can continue to improve. One area would be user interface and dashboard customization. While the platform provides a lot of valuable information, new users can sometimes face a learning curve when navigating and investigating and creating customized views. More intuitive dashboards would simplify workflows and help analysts access critical information even faster. Another area for improvement is reporting and analytics. The existing reporting capabilities are useful, but more flexibility and customizable reporting options would make it easier to generate executive-level summaries, compliance reports, and operational metrics for different audiences.
Mohan Janarthanan - PeerSpot reviewer
Associate Vice President at Novac Technology Solutions
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.
