Viper vs Sentinelgate

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.; Sentinelgate: SentinelGate is a self-hosted, container-native, zero-lock-in proxy that intercepts every action of an AI agent before it executes, applying deterministic rules to block unauthorized tool calls, shell commands, and file operations. It provides a full audit trail, content scanning, and session-aware policies, and works with any MCP-compatible client or sandbox.
