That sentence should keep you awake.
Identity-Aware Proxy (IAP) is no longer optional. It’s a first-line defense for internal tools, production dashboards, staging environments, and admin consoles. But deploying an IAP is not enough. If you are not baking vendor risk management into your IAP strategy, you are trusting every connected service, SDK, and plugin to be as secure as your own code—when most are not.
The intersection of IAP and Vendor Risk Management is where many teams stumble. The proxy authenticates users, but what about the third-party APIs it calls? The infrastructure providers that route your requests? The embedded analytics or payment widgets? Each of these vendors has their own attack surface, patch cadence, and secrets handling. A compromised vendor can become a side door into your systems despite a perfect IAP configuration.
A sound approach starts with full visibility. An inventory of every vendor connected to systems behind your Identity-Aware Proxy is a baseline requirement. Map access scopes, credentials, and IP ranges. Track which endpoints these vendors can reach and how. Your IAP logs are a goldmine here—filter them, correlate with vendor identifiers, and spot unexpected requests or locations.
Next, enforce zero-trust not just for users but also at the vendor layer. Token scopes should be minimal and time-bounded. Any vendor connection that doesn’t need to live inside your IAP environment shouldn’t be there. Segregate environments, isolate credentials, and never grant persistent access unless audit requirements demand it.
From there, automate monitoring and response. Set up continuous vendor security scoring. Flag anomalies: a traffic spike from a vendor network, credentials being used from unapproved geographies, TLS downgrades, or new endpoints being hit. Incident readiness should assume vendor compromise and your IAP policies should degrade gracefully, limiting blast radius without taking down critical services.
Finally, make vendor evaluation part of your deployment lifecycle. Before approving a new SaaS integration behind your IAP, require security documentation, SOC 2 or equivalent, breach history, and encryption practices. This is not red tape—it is closing an exposure before it exists.
Identity-Aware Proxy is only as strong as the weakest vendor in its scope. When you pair tight access control with disciplined Vendor Risk Management, you turn a single security feature into an integrated defense posture.
You can see what this looks like in action today. hoop.dev lets you deploy a secure, identity-aware environment with vendor-aware controls in minutes. No long setup cycles. No blind spots in your logs. Just a clear, locked door that only the right people—and the right vendors—can get through.
