Knostic

Knostic is a Web and API enterprise AI security platform for security, risk, and compliance teams adopting LLMs and AI assistants across the organization.

Key capabilities include:

• Need-to-know access controls for LLMs, with prompt-level enforcement that can redact or block sensitive content based on user permissions to reduce data leakage
• Shadow AI discovery and monitoring across employee usage (including browsers and IDEs), helping teams find unsanctioned tools and risky workflows
• Data exposure risk assessment that simulates employee roles and queries to identify oversharing in environments like Microsoft 365, then produces prioritized remediation guidance
• Real-time protection for assistants and coding tools, including data masking and blocking destructive commands (for example, preventing dangerous actions like rm -rf)

Pricing: Paid, enterprise pricing; offerings include Microsoft Copilot Security and Data Exposure Risk Assessment with ongoing analysis.

Notable for combining governance, visibility, and runtime controls in one platform, with native integrations including Microsoft Graph API, Azure OpenAI, Microsoft Purview (for DLP), Glean, VS Code, Cursor, and SIEM tooling. It is also available via AWS Marketplace and Microsoft Marketplace.
