SikkerGuard is SikkerAPI’s newest product release, a Docker container that pulls the SikkerAPI threat blacklist and blocks known malicious IPs at the kernel level using iptables and ipset. It runs alongside your services with zero config beyond an API key, auto-whitelists your gateway/DNS/LAN to prevent lockouts, logs blocked connections in real time, and rolls back if connectivity breaks. Works with the free plan and reports blocked IPs back to your dashboard.

SikkerAPI is an IP reputation service powered by high interaction honeypot data and community reported incidents. Look up an IP for threat intelligence, a confidence score and geo data.
