AI Security

Protect all your agents, even the ones you just found out about

Secure the entire lifecycle of agentic and AI-native applications.

Why Teams Switch

AI changed the threat model

Shadow AI

No visibility into AI assets

No way to tell where LLMs, MCP servers, or agents are used in your applications

AI Discovery

Automatically discover and inventory every AI asset in your environment

AI Threats

Existing tools don't stop AI threats

Existing security tools don't catch prompt injection, data leakage, or other AI risks

AI Firewall

Detect and stop AI threats like prompt injection and data leakage in real time

LLM Risks

AI vulnerabilities found too late

By the time AI risks surface in production, the damage is already done

AI Testing

Test every AI asset and agent against OWASP Top 10 LLM and MCP risks

AI Discovery

Eliminate AI blind spots

Get complete visibility into every agent and AI asset — LLMs, MCP servers, and AI APIs — with continuous monitoring, risk scoring, and inventory.

Continuous discovery. Monitor AI API traffic to automatically discover every LLM, MCP server, AI service, and agent in use, including 3rd-party services.

AI asset risk scoring. Evaluate every discovered AI asset for authentication, encryption, internet exposure, and known vulnerabilities using a proprietary risk score.

Complete AI asset inventory. Get a full, continuously updated inventory of your entire AI attack surface, with risk scores and sensitive data details for each.

AI Firewall

Protect AI in production

Detect and block AI-specific threats in real time — prompt injection, data leakage, and policy violations — without breaking user experience.

Prompt injection protection. Detect and block prompt injection attacks in real time, preventing data exfiltration and malicious outputs before they reach users.

Data leakage prevention. Inspect every prompt and response for PII and sensitive data flowing through your AI APIs and MCP endpoints.

Token limit enforcement. Set token budgets per model to cap consumption and prevent token implosion — to protect against runaway costs and AI stack instability.

AI Testing

Catch AI risks pre-deploy

Test LLMs, agents, and AI APIs for AI-specific risks before they reach production — automatically configured from your actual traffic.

OWASP Top 10. Test AI assets against the OWASP Top 10 LLM and MCP risks, including prompt injection, data leakage, and insecure outputs.

Automatic test configuration. Simplify configuration and reduce overhead by creating AI security tests using your actual AI traffic in production.

Seamless CI/CD integration. Orchestrate AI security testing across all your AI pipelines to automatically test every AI application before deployment.

FAQs

Frequently asked questions

AI-native application security is the practice of securing applications built with AI components such as LLMs, MCP servers, and third-party GenAI services. It requires runtime visibility into AI APIs, data flows, and model behavior to detect threats specific to AI systems — unlike traditional approaches focused solely on code vulnerabilities.

The AI blind spot refers to undiscovered AI components deployed without security team awareness. 62% of security practitioners say they have no way to tell where LLMs are in use across their organization, creating exploitable gaps that attackers can target.

Discovery requires continuous monitoring of runtime traffic to identify every LLM, MCP server, and GenAI service. Runtime API traffic analysis can detect AI assets as they appear — including shadow AI that was never formally inventoried.

MCP security protects connections between MCP servers, clients, tools, and resources. MCP servers represent a significant and often overlooked attack surface that requires continuous monitoring and vulnerability assessment.

AI-SPM continuously assesses the security posture of AI assets including authentication, encryption, exposure, and data flows, providing a risk-based view of your AI attack surface.

Prompt injection inserts malicious instructions into LLM inputs. Protection requires real-time inspection of prompts and model responses at the API layer to detect and block malicious inputs before they reach the model.

All AI components communicate via APIs. Without deep visibility into runtime API traffic, security teams cannot discover all AI assets, monitor their behavior, or detect threats in real time.

AI security adds runtime protection layers that traditional tools lack. Static code analysis alone cannot detect threats like prompt injection, LLM jailbreaking, or sensitive data leakage through AI APIs.

Compliance requires automated discovery, risk scoring, and policy enforcement. Out-of-the-box compliance policies aligned with frameworks like the OWASP LLM Top 10 provide a starting point for governance.

LLM security protects models from prompt injection, jailbreaking, data leakage, and overconsumption. It requires visibility into every API connection to and from the model and continuous monitoring of model inputs and outputs.
