Description

Constellation Gate AI serves as an auxiliary defense mechanism for AI agents, positioned strategically between the agent and the model to filter all requests for potential threats and data leaks. This solution functions as an inline gateway for coding agents and model APIs, ensuring protection of workflows while eliminating the need for significant code modifications. Users can direct existing tools such as Claude Code, Cursor, OpenClaw, Codex, or OpenCode to utilize Gate, thereby gaining access to defenses against prompt injection, secret detection, PII redaction, token optimization, and a reliable audit trail. The platform specifically addresses three critical vulnerabilities: prompt injection attacks, leakage of credentials and PII, and unauthorized tool calls. Rather than depending on the model's self-defense mechanisms, Gate preemptively intercepts attacks before they penetrate the model, removes sensitive information prior to the return of responses, and prevents outputs from compromised tools before an agent can act on them. Gate is compatible with the existing calls made by agents, relaying them to the model while meticulously scanning each request and response in both directions, ensuring comprehensive protection against emerging threats. This proactive approach not only enhances security but also instills confidence in users about the integrity and safety of their AI workflows.

Description

Mountain Theory is the antivirus for AI: every action an AI agent is about to take is checked against your rules before it runs. Mountain Theory controls what autonomous AI agents can do. Every action an agent is about to take is checked against your rules before it runs, and comes back ALLOW, HOLD or BLOCK. An agent that works around a block is stopped on the workaround. An agent that drifts off its task is caught. New bad behavior is stopped the day it appears, with no new rule written. Personal data is kept from leaving your environment, and instructions hidden in emails and documents are blocked. Rules are plain English, so changing one takes no code. Every decision is logged for your auditor. It works with any AI you already use, in your environment or the cloud. Our recorded tests are published with the misses included.
