Prisma Access vs Tailscale

Prisma Access is a cloud-delivered security solution for users, applications, devices, and data across office, branch, and remote locations. It provides least-privileged application access and is designed to reduce reliance on traditional VPNs. Secure Web Gateway protection addresses web threats, while CASB capabilities provide SaaS visibility, inline and API-based controls, and contextual policies for sensitive data. Firewall as a Service adds threat prevention, application control, and Zero Trust policies. Prisma Agent connects users to organizational networks, SaaS applications, and the internet while extending security policies to their devices. The agent supports Windows, macOS, Linux, iOS, and Android, with requirements varying by platform. Authentication integrations include Cloud Identity Engine, SAML, TACACS+, RADIUS, LDAP, Kerberos, MFA, and local database authentication. Administrators use Panorama or Strata Cloud Manager, but must select the interface before setup because it cannot later be changed. Insights APIs monitor deployment health and performance. The service is paid, has no free plan, and pricing is on request.

Tailscale is a zero-config VPN for connecting users and devices across a network. It uses WireGuard to form low-latency peer-to-peer connections, which Tailscale says are end-to-end encrypted so it cannot read users’ traffic. Administrators can use access control lists to specify which users may connect to which devices. Supported identity providers handle authentication, and SCIM supports user and group provisioning. Monitoring features include configuration audit logs, network flow logs, webhooks, and log streaming to SIEM partners. Device posture information can be used in connectivity rules. Taildrop transfers files between devices, while node sharing lets users share a node without exposing it to the public internet. The service runs on Android, iOS, Linux, macOS, web, and Windows. Personal is free forever for non-commercial use and supports up to six users; Standard costs $8 per user per month. Premium costs $18 per user per month and includes priority support.
