Viper vs ironcurtain

Viper: VIPER is a powerful and flexible red team platform designed for adversary simulation and cybersecurity assessment. It integrates core tools, an LLM agent, and over 100 post-exploitation modules to efficiently complete red team operations.; ironcurtain: IronCurtain provides a secure runtime for autonomous AI agents, enforcing security policies derived from human-readable constitutions to prevent issues like prompt injection. It ensures agents operate within defined boundaries through mechanisms like V8 isolates and a policy engine that mediates all tool calls.

Features

Viper logoViper
01Intuitive User-Friendly Interface for rapid task initiation.
02Multi-Platform Support for Windows, Linux, and macOS.
03Comprehensive Red Teaming Tools covering all MITRE ATT&CK phases with over 100 modules.
04Integrated LLM Agent for enhanced automation and intelligent decision-making.
05Custom Extensibility via Python-based module development and advanced functions like defense evasion and pivot graph.
ironcurtain logoironcurtain
01Constitution-driven Security Policy: Define security intent in plain English, which is then compiled into deterministic and enforceable rules.
02Semantic Interposition & Runtime Enforcement: All agent interactions and tool calls are routed through a policy engine that allows, denies, or escalates based on policy.
03Untrusted Agent Model: Assumes the LLM may be compromised (e.g., by prompt injection or drift), enforcing security at the boundary regardless of the model's behavior.
04Multi-mode Operation: Supports both an internal LLM agent running in a V8 sandbox (Code Mode) and external agents running in Docker containers (Docker Agent Mode).
05Built-in Capabilities: Ships with pre-configured MCP servers for filesystem, Git, web fetching, and GitHub operations, all governed by policy.
