Hi, Understanding the where your end-points are located within the organization is also very important. Due to the current situation, where everyone is working from home, there is a constant threat to end-points that are accessing the corporate resources through VPN/remote access/Citrix. Now, for internet/private access, the users would need to create a VPN to your environment which is a waste of bandwidth. This where a web gateway comes into picture. A web gateway can be a solution for both your on-prem or off-prem end-points. It provides protection for all your end-points for port 80/443 traffic (URL-filtering, AV, Anti-spyware, DLP, threat prevention etc.) inline with your current security posture (on-prem Palo alto firewall) I recently did a web gateway implementation (Zscaler) for a big client with 10000 users. They had Palo alto firewall on prem. The gateway was only for the roaming clients. The way we had it setup was, on the company LAN, Zscaler would disconnect automatically and 80/443 traffic would go through the palo-alto firewall. But if a user is remote on untrusted network Zscaler will enforce the traffic through the proxy node and apply all the security policies configured, which ensures that users can't go to any unwanted websites through company provided laptops. Your choices for web-gateway solution can be Palo Prisma access, Zscaler, Netskope, Cisco secureX Hope this helps.
