“IronShield cut scraper traffic by 92% without a single customer complaint. Setup took minutes, and the added latency is imperceptible. Our team finally stopped babysitting brittle rules.”
Keep your stack. Strengthen your defenses.
CDNs and WAFs are great for performance — but they weren’t built for adaptive AI scrapers. IronShield drops in to protect what they can’t.
Seamless for real users
CAPTCHAs frustrate humans more than bots. IronShield keeps UX seamless — no puzzles, no lost conversions.
Replace rulesets: rules don’t scale
Custom rules break as scrapers evolve. IronShield adapts automatically — no brittle rule‑writing required.
Make scraping too expensive
WAFs block some bots, but smart scrapers keep coming. IronShield shifts the economics with small client work that’s trivial for a user and costly at scale.
Engineered for the modern web.
Built to deploy fast, scale globally, and stay invisible to real users.
Deploy in 5 minutes
One-click Domain Connect or a simple CNAME. Self-host via Docker or run on Cloudflare Worker.
L7 DDoS & Rate Limiting
Application-layer filtering for HTTP, WebSocket, and API routes. Blocks floods without hurting real users.
