Local-First Cryptographic Storage & Sub-Millisecond Endpoint Defense.
Cyzog engineers standalone Windows security binaries that execute 100% on-device. No cloud accounts, no background telemetry daemons, and no remote API dependencies. Built for systems engineers, developers, and operators who verify math rather than trusting third-party custodians.

C127G Vault (v2.1.0)
C127G is a standalone, air-gapped secrets manager. Whether concealing personal crypto seed phrases inside standard .png images via True LSB Pixel Steganography, or generating complex .env files for production servers, C127G seals your data with 256 MiB Argon2id and AES-256-GCM.
True PNG LSB Steganography
Weave your encrypted vault payload directly inside lossless .png carrier images with 0.39% optical variance.
1-Click Developer .env Export
Select multiple API keys and database URIs to generate formatted .env files without clipboard leaks.
Plausible Deniability Vaults
Configure a secondary duress password that mounts a believable decoy vault under physical coercion.
Argon2id + AES-256-GCM
RFC 9106 memory-hard key derivation paired with authenticated 256-bit AES-GCM encryption.
Agent Sentinel (C1-AG v1.0)
Stop feeding proprietary secrets to cloud LLMs or giving untrusted MCP servers unguarded shell access. Agent Sentinel (C1-AG) strips API keys, .env secrets, and PII in 0.58 ms via local ONNX NER (<CYZOG_SECRET_1>), restores responses locally across SSE streams, blocks MCP reads to ~/.ssh, and freezes destructive child commands via NtSuspendProcess.
Zero-Leak Localhost Proxy
Drop-in 127.0.0.1:8787 gateway for Cursor, Claude Code, OpenAI, Anthropic, and Gemini.
Credential Vault Blocklist
Blocks silent MCP tool reads to ~/.ssh, ~/.aws, Chrome Login Data, and crypto wallets.
1-Click HUD Command Approval
Suspends AI-spawned rm -rf, Remove-Item -Recurse, and DROP TABLE threads instantly.
$29 Solo Pro / $199 Team
Perpetual license for up to 3 dev rigs ($29) or annual fleet compliance ($199/seat/yr).
The Cyzog Manifesto
We engineer software under one uncompromising axiom: If your master secrets never touch a network socket, they can never be breached in the cloud.
The Cloud Is Someone Else's Attack Surface
Centralized cloud vaults aggregate millions of master keys into the world's most lucrative target. Through supply-chain compromise, rogue insiders, or subpoena, cloud-hosted secrets remain structurally vulnerable.
Intelligence Must Execute on Local Silicon
AI should be a local shield, not a cloud surveillance sensor. Our quantized ONNX models evaluate byte-stream Shannon entropy directly on your CPU in under 1.8ms.
Transparent Cryptography
Zero proprietary "black-box" ciphers. We strictly deploy peer-reviewed standards: 256 MiB Argon2id key derivation and authenticated AES-256-GCM.
Verifiable Anonymity
Zero analytics SDKs, zero crash webhooks, zero background ping-backs. Verify with Wireshark: outbound traffic remains 0.00 KB/s permanently.
Sub-Millisecond Autonomy
Freezes ransomware threads via NtSuspendProcess, carves session keys from RAM before termination, and rolls back files via VSS snapshots.
"True security is not a subscription service managed by a third party. It is a mathematical barrier engineered into the software you run on your own hardware."
Engineered & Verified Locally
Active post-quantum cryptography research tracks and deterministic PowerShell binary checksum verification.
ML-KEM-1024 Hybrid Post-Quantum Vault Wrapping
