Gray Swan Platform

Adversarial red teaming and inline runtime protection for LLM and AI agent deployments.

LLM SecurityAI Red Teaming

Gray Swan Platform Overview

What it does

The Gray Swan Platform combines adversarial AI red teaming with runtime protection for enterprises deploying large language model (LLM) applications and AI agents. Its Shade component runs autonomous adversarial campaigns that adapt, escalate, and chain attack techniques against a target system, while its Cygnal component sits inline to classify adversarial inputs and unsafe outputs in real time. The pairing exposes weaknesses in an AI system and then blocks the same attacks in production.

How it works

Shade uses an LLM-powered adversarial agent, drawing on attack data from a network of more than 15,000 AI red teamers, to scope campaigns to a target's model, guardrails, tools, and retrieval systems, then returns reproducible transcripts, severity ratings, and a prioritized remediation roadmap. Cygnal deploys inline between users, models, agent tool calls, and retrieval pipelines, validating every prompt, response, and tool interaction against custom policies in milliseconds with configurable block, flag, or rewrite actions. Both integrate through a lightweight API and log every classification for review.

Credentials and traction

SOC 2 Type II certified, with the audit report available through the company's Trust Center, and Cyber Essentials certified. Gray Swan serves more than 20 enterprise customers and is relied on as an adversarial evaluation standard by frontier AI labs, including OpenAI, Anthropic, and Google DeepMind. It has run public agent red-teaming challenges with the UK AI Safety Institute and the U.S. AI Safety Institute, targeting enterprises deploying AI agents and the labs building frontier models.

Key Capabilities

mapped to solution categories
LLM Security

Detects and blocks adversarial inputs designed to override system prompts, extract training data, or redirect model behavior. Detection approaches include pattern matching, input semantic analysis, and secondary model classification.

Evaluates model outputs against content policy, data classification rules, and format expectations before delivery to end users, blocking responses containing sensitive data or policy violations.

Intercepts prompts and completions to prevent sensitive data (PII, credentials, internal IP), from being transmitted to external LLM services or returned in model responses.

Records prompts, completions, and metadata for all AI interactions with tamper-resistant storage, supporting compliance, forensics, and policy investigation.

Enforces IAM-style policies on LLM API access, controlling which users and applications can invoke which models and data sources, with audit logging.

Continuously stress-tests the product's own guardrails and filters against jailbreaks, prompt-injection payloads, and data-extraction attempts, then re-tightens policies after model or prompt changes. A self-validation loop within the runtime protection layer, distinct from the standalone AI Red Teaming discipline that tests AI systems end to end.

AI Red Teaming

Autonomously plans and executes multi-step adversarial campaigns against AI systems, emulating real attacker workflows across reconnaissance, exploitation, and escalation rather than running a fixed checklist of tests.

Attacks AI agents through their tools, memory, and connected services using multi-step techniques such as tool misuse, goal hijacking, and indirect injection, surfacing exploit paths unique to autonomous agents.

Tests LLMs and AI applications against a library of direct and indirect prompt-injection and jailbreak techniques, reporting which payloads bypass system instructions and safety controls.

Attacks deployed guardrails, system prompts, and content filters to measure how reliably they block adversarial inputs, quantifying bypass rates rather than assuming the controls work.

Routes high-value automated findings to specialist AI red teamers for manual exploitation, chaining, and depth beyond automated coverage, blending platform testing with human expertise.

Re-runs red-team campaigns continuously and at release gates in the CI/CD pipeline as models, prompts, and configurations change, catching new exploit paths before and after deployment.

Tests AI agents and their tool chains for context-poisoning, tool-misuse and indirect prompt-injection vulnerabilities.
