Cipher Black v0.3.0 — Unified Security Suite (Digital Download)

Cipher Black is a unified security suite built around a single command-line tool and local dashboard. This license covers version 0.3.0.

Platform support

• Linux — fully supported. Every module (VPN kill switch, firewall, DNS filter, endpoint guard, behavioral detection, ransomware rollback) runs and is tested here.
• Windows & macOS — partial. The VPN kill switch works on both; per-application firewall enforcement and the endpoint guard's process-launch hook are still in development and not yet functional outside Linux.
• Mobile (iOS/Android) — not supported. There is no mobile client in this release.

What's included

• VPN kill switch with real nftables enforcement and multi-hop relay support
• Default-deny firewall (NFQUEUE-based)
• DNS filtering, forced through the VPN tunnel with fail-closed behavior
• Endpoint guard with hash-pinned allowlisting
• Reputation scanner and phishing/lookalike-domain alerts
• Behavioral detection and ransomware rollback
• Identity & dark web breach monitoring
• Local dashboard UI and an optional native desktop shell with tray icon
