Edge Middleware for SaaS Access Control
A no-code edge gateway that sits in front of popular B2B SaaS applications to add missing security features like cookie-based authentication, URL encryption, and IP restriction. It allows companies to secure external tools without writing custom reverse proxies.
Why this matters
You are managing operations using expensive, industry-standard third-party software for customer support or media hosting. You want to restrict access to certain articles to paying customers only, or you need to hide source image URLs to prevent theft. You realize the expensive software you pay for lacks these fundamental security features. You end up having to deploy your own custom middleware or edge functions to intercept requests, validate cookies, and proxy the traffic, which is completely outside your core product scope.
- · Built for Operations and IT teams managing third-party SaaS tools.
- · Most likely monetization: SaaS subscription based on traffic volume.

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1The targeted SaaS companies might update their Terms of Service to explicitly ban reverse proxying of their applications.
- 2Enterprise customers may require complex compliance certifications (SOC2) before passing traffic through your proxy.
- 3The SaaS companies could eventually release native authentication features, rendering your middleware unnecessary.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Multiple engineers described writing trivial but essential stateless scripts that run on edge nodes to modify the behavior of hosted services they rely upon. Examples included encrypting URLs to protect source assets and gating knowledge base articles based on custom authentication cookies. This highlights a clear gap where expensive third-party tools fail to provide granular access controls, forcing customers to build bespoke reverse proxies to meet their security requirements.
