Stop API Abuse Before It Starts

Your WordPress REST API endpoints are under constant attack and traditional rate limiting alone isn’t enough. You need dual-layer protection that stops abuse immediately AND permanently blocks repeat offenders.

The Problem

Single-Layer Security Isn’t Enough

Rate Limiting Alone

• Temporary blocks then resets automatically.
• Attackers return after the limit expires.
• Manual intervention required for persistent threats.
• Resource waste from repeated attacks.

IP Blacklisting Alone

• No immediate protection against initial attacks.
• Manual management of blacklists.
• False positives can block legitimate users.
• Reactive approach instead of proactive.

The Solution

Dual-Layer API Security

Layer 1: Intelligent Rate Limiting

• Immediate protection that adapts to your traffic patterns.
• Smart Detection: Automatically adjusts limits based on traffic.
• Instant Response: Blocks excessive requests within seconds.
• Fair Usage: Ensures legitimate users aren’t affected.
• Real-time Monitoring: Tracks request patterns in real-time.

Layer 2: Violation-Based Auto-Blacklisting

• Permanent protection against repeat offenders
• Pattern Recognition: Identifies persistent attackers.
• Automatic Blacklisting: Permanently blocks after multiple violations.
• Zero False Positives: Only blocks confirmed abusers.
• Self-Healing: Automatically manages blacklist lifecycle.

How Dual-Layer Protection Works

The Security Flow

1. Attacker makes excessive requests.
2. Rate limit immediately blocks (429 error)
3. Violation is recorded and tracked.
4. After multiple violations → Auto-blacklisted
5. Attacker permanently blocked.

Real-World Example

Scenario: Malicious IP 192.168.1.100 attacks your API

Time	Requests	Rate Limit	Violation Count	Result
0:00	100 req/min	✅ Blocked	1	429 Error
0:05	100 req/min	✅ Blocked	2	429 Error
0:10	100 req/min	✅ Blocked	3	429 Error
0:15	100 req/min	✅ Blocked	4	429 Error
0:20	100 req/min	✅ Blocked	5	🔒 PERMANENTLY BLOCKED

Result: Attacker stopped immediately AND permanently removed.
