Today's encryption has an expiration date.

Quantum computers will break RSA and ECC. Adversaries are already harvesting encrypted data to decrypt later. Progralink builds the cryptographic infrastructure that's ready before they are — from post-quantum algorithms to the products that use them.

DevCage

Secure Sandbox for AI Coding Agents

Let AI write code. Don't let it own your machine.

Run AI coding agents in isolated Docker containers with seven layers of security. DevCage intercepts and controls filesystem, network, and process access, keeping your system safe while AI writes and executes code.

Docker Isolation 7+ Security Layers 40+ Tools
  • Supports Claude Code, Gemini CLI, Codex CLI, Aider, and more
  • Granular filesystem controls with read/write/deny path rules
  • Network traffic interception with domain-level allow/block lists
  • Pre-configured development environments for major languages
  • Automatic git integration and workspace mounting
  • Real-time resource monitoring and process isolation

SecuDB

The Encrypted Database Built for AI

If AI made the decision, SecuDB proves it.

Encrypted-by-default storage for AI-generated data, model outputs, and sensitive datasets. Immutable audit trails prove data provenance and lineage. Tamper-evident chain-linked records ensure outputs cannot be silently altered.

Post-Quantum Encryption Chain-Linked Integrity Event Sourcing
  • Events (immutable AI decisions), Entities (versioned configs), Files (encrypted datasets)
  • Event-sourcing architecture captures AI decision history for explainability
  • Multiple backends: filesystem, S3, SMB — deploy anywhere
  • Automatic versioning with complete change history
  • Encryption at rest with optional end-to-end encryption
