I'm Security Engineer, Author of Data-Shield IPv4 Blocklist and Open Source Lover

The Data-Shield IPv4 Blocklist Community provides an official, curated registry of IPv4 addresses identified as malicious. Updated continuously, this resource offers vital threat intelligence to bolster your Firewall and WAF instances, delivering a robust, additional layer of security for your infrastructure.

SysWarden is an Enterprise-grade Default-Deny Host Intrusion Prevention System (HIPS) designed for critical Linux infrastructure. It enforces automated a part of CIS Level 2 hardening, integrates global Threat Intelligence, and orchestrates dynamic network defense with a near-zero performance overhead.

It acts as a ruthless first line of defense. By fusing dynamic firewall orchestration (nftables/iptables), global Threat Intelligence (Data-Shield IPv4, GeoIP, ASN), a reactive HIPS (optimized Fail2ban), and SIEM alert routing, SysWarden filters out Internet "background noise" and neutralizes threats at the network (L2/L3/L4) and application (L7) levels. It perfectly complements modern EDR/XDR architectures by drastically reducing their analysis surface and the server's CPU load.
