How Protection Works

Three Steps. Zero Configuration.

You focus on building. ShieldGuard handles the attacks.

1

Install

WordPress: upload a zip. Shopify: one-click app install. API: add middleware. Done.

2

Detect

Every request scored in real-time. XML-RPC attacks, card testing, bot UAs, SQLi, XSS, SSRF — all caught.

3

Sleep Easy

Threats blocked automatically. Alerts via email or Slack. Review attack logs anytime. Your site stays safe.

What It Protects

Every Attack Vector, Covered

ShieldGuard blocks the threats that actual attackers use — not marketing bullet points.

XML-RPC Firewall

The #1 WordPress attack vector. ShieldGuard blocks brute force via xmlrpc.php by default. No settings needed.

Brute Force Protection

Rate limits login attempts to 5 per IP. Known attacker IPs blocked at the edge. Credential stuffing? Stopped cold.

Card Testing Detection

Shopify & WooCommerce: detects velocity patterns in checkout. Stops fraudsters burning stolen cards on your store.

Rate Limiting

Token-based, IP-based, or endpoint-based. Protect your API budget from abuse. Per-user, per-endpoint granularity.

Bot Detection

UA analysis, headless browser fingerprinting, mouse/keyboard timing. Separates Googlebot from scrapers. 98.5% accuracy.

Spam Protection

Comment spam, disposable emails, keyword analysis. Keeps your content clean without CAPTCHA hell for real users.

Built for developers, by developers

ShieldGuard is open-source. We built it to protect our own properties — catn.site, jobrdy.online, urentmy.com, and five others. Zero attacks bypassed. Zero false positives. Now we're sharing it with you.

Open Source First

MIT licensed. Inspect every line. Run it yourself. Contribute on GitHub. No black boxes.

No Vendor Lock-In

Self-host or use our cloud. Your attack data stays on your infrastructure. Export anytime.

128 Tests & Counting

TDD-built from day one. Every detection rule has a test. Every test proves a real attack is blocked.
