The firewalls are gone. The perimeter is dead. Users, apps, and data move everywhere. Access must follow — without breaking security. HashiCorp Boundary with Zscaler is how you do it.
Boundary gives you identity-based access to private systems. No static credentials. No VPN sprawl. Zscaler delivers zero trust network access from any device, any location. Together, they remove the need for exposed hosts, public IPs, or open inbound ports. You get secure, brokered connections with central control.
Integration is straight. Configure Boundary to authenticate users via Terraform or CLI. Use Zscaler Private Access (ZPA) rules to grant access only to approved services. Boundary handles session authorization and credential injection. Zscaler handles encrypted transport and policy enforcement. Each service covers a layer: Boundary for permissions and workflows; Zscaler for network invisibility and attack surface reduction.
