VPN and Proxy Detection for SaaS Login Security
Use VPN, proxy, and IP reputation signals to protect SaaS accounts without blocking privacy-conscious users unnecessarily.
Why SaaS teams check proxies
SaaS apps protect sensitive business data, so login from anonymous or high-risk networks may require extra verification.
Proxy and VPN signals are useful when combined with account role, device trust, and recent login history.
Avoid unfair blocking
Many legitimate users connect through VPNs for work, travel, or privacy. Blocking all VPNs can hurt normal workflows.
Risk-based challenges are often better than blanket denial.
Recommended workflow
Allow low-risk sessions, challenge unusual sessions, alert admins for privileged access, and log proxy indicators for audit trails.
