Featured Reviews

Ashutosh Jha - PeerSpot reviewer
Project Engineer at IT Solution
Robust protection has blocked external threats and provides clear visibility into user activity
Sophos Firewall offers multiple features, including IPS, IDS, ATP, NDR, XOps, web protection, application protection, web server protection, and many more. Out of all those features, I find web protection and application protection to be very helpful and valuable in my daily work. Sophos Firewall has positively impacted my organization by preventing outside threats, allowing me to easily monitor my users, and configuring any rule for any user regarding what they need to use and what I am restricting for the particular user. I can share that it has improved productivity because if anyone could ransom my network, they could demand money to decrypt the files, thus saving us money, time, and providing reliability.
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.
