IronClad Kernel Firewall

Ironclad Kernel: The Firewall That Sees Processes, Not Just Packets.

Stop fighting modern threats with legacy tools. Traditional firewalls only see IP addresses and ports, making them blind to malicious scripts using legitimate channels like port 443. Ironclad Kernel changes the game by moving security enforcement directly into the Linux Kernel using eBPF technology.

Why Ironclad Kernel?

• Identity-Based Security: We don't just block IPs; we block processes. Ironclad allows apt-get to update while instantly blocking a malicious Python script attempting the exact same connection.

• DDoS Mitigation: Implements token bucket rate limiting directly in the kernel to drop excessive connection attempts before they consume resources.

• Wire-Speed Performance: Experience near-zero overhead. With <1% CPU usage at 10Gbps throughput and <500ns latency per connection, security no longer means sacrificing speed.

• Global Scale Defense: Block tens of thousands of country-specific IP ranges instantly using LPM Tries, achieving O(1) lookup speeds that linear scanning can't match.

• True Zero-Trust: A default-deny architecture that intercepts connect() syscalls to block unauthorized outbound connections at the source.

• Resilient Operations: Features "Boot-Race Protection" to ensure threat feeds are loaded before network traffic is allowed, and a "Fail-Safe Mode" that keeps protections active even if the userspace daemon crashes.
