What is Mountain Theory?

Mountain Theory is AI security for companies running autonomous AI agents. Before an agent's action runs, Mountain Theory checks it against your rules and allows it, holds it for a person to approve, or blocks it. It stops an agent working around a block, catches an agent drifting off the task it was given, and stops new bad behavior on the day it first appears, with no new rule needed. It also keeps personal data from leaving and blocks instructions hidden in documents. Rules are written in plain English with no code. Every decision is logged for your auditor. It works with any AI you already use, in your environment or the cloud. We publish our recorded tests, misses included.

What is Harden?

Harden AIF is a dedicated security solution tailored for AI coding agents, focusing on safeguarding agent endpoint security by evaluating tool calls before they are executed, taking into account the developer's intent, the context of the session, the organization’s policies, and the potential consequences of the proposed action. This platform is adept at protecting against various threats, including harmful commands, unauthorized access, accidental data transfers, exposure of sensitive information, misuse of privileges, and other potentially dangerous actions performed by agents. By allowing legitimate operations to continue smoothly, it also ensures the safe redaction of sensitive data during approved workflows while blocking actions that stray from the developer's original intent or surpass their authority. Harden AIF's compatibility with a range of popular coding agents and development tools, such as Claude Code, Codex, Cursor, Antigravity CLI, Kiro, Hermes, and OpenClaw, establishes a consistent security framework across the agent ecosystem. This thorough methodology not only bolsters security measures but also cultivates a more secure environment for developers engaging with AI technologies. Furthermore, its ability to adapt and integrate with emerging tools signifies a forward-thinking approach in the ever-evolving landscape of AI development.
