The Gatekeeper Server Client is the free integration component that connects your website or application to your subscribed Gatekeeper environment. It receives access attempts that begin through the Gatekeeper button and forwards them for evaluation through your protected verification process.

By using the Server Client, you remove public-facing login fields from the critical path. Visitors never type passwords or codes into your pages. Instead, the Gatekeeper button initiates a controlled sign-in sequence. The decision to allow or deny access is returned to your system without exposing the internal mechanisms that reach that decision.

When Gatekeeper is widely deployed across sites and services, common attacks against login pages lose their targets. There are no credential fields to harvest, no forms to brute-force, and no SMS or email codes for attackers to intercept. Automated intrusion attempts lose their leverage because the traditional entry points are no longer present.

The Server Client is designed to be lightweight and predictable. It can be hosted on a dedicated Gatekeeper server or alongside existing infrastructure, depending on how you choose to deploy. Once installed and configured with your subscription details, your website or application can start using the Gatekeeper button as the primary entry mechanism for protected areas.

The Gatekeeper Server Client itself is free. Using it in a live environment requires an active Gatekeeper subscription that defines how many protected systems, users, or environments are covered under your plan.
