How does SASE reverse proxy architecture replace VPNs while improving security?

Modern SASE platforms use Zero Trust Network Access (ZTNA) to eliminate VPN vulnerabilities through reverse proxy connections instead of network tunneling. Application connectors deployed near your core banking systems make outbound calls to the SASE cloud, while users connect through the cloud to access specific applications like FIS Horizon. Users never receive direct network access—they can't ping, port scan, or map your infrastructure even if their devices are compromised. This "dark network" approach prevents lateral movement during breaches while providing seamless application access. Our ZTNA implementation eliminates VPN security gaps without disrupting productivity.
