Stop the Noise: Build Your Own Smart App Firewall with Rust and Pingora
Tired of endless vulnerability scans, bot traffic, and noisy probes cluttering your logs—and wasting your resources? Wish your WAF actually understood your app instead of being just another generic filter?
What if you could build a high-performance, tailored firewall that blocks exactly what you want—with full control?
Thanks to Cloudflare’s open-source Pingora, you can. This Rust create already powers 40+ million requests per second and gives you the perfect base to craft your own custom application guard.
With a bit of Rust, you can:
- Rate-limit like a boss
- Instantly 404 malicious requests from known security lists
- Tailor protection to your exact APIs and patterns
And the best part? Every blocked request means less load, faster performance, and a slightly greener footprint.
No prior Rust experience required—I'll walk you through approachable code that anyone with dev experience can follow.
How to switch from cozy NodeJS to scary Rust as a company.
What are the pitfalls and the challenges? And how can you convince skeptics, from CEOs and developers, without making them hate you (which they might do, just a little, sometimes, especially around the borrowchecker).
This is a short tale of our journey, why we wanted Rust, where you might begin and what to avoid (even if the results with Rust might be better than NodeJS).
