Knostic Platform

Detects AI knowledge oversharing and enforces need-to-know access for copilots, LLMs, and agents.

Knostic Platform Overview

What it does

Knostic gives enterprises visibility and control over how copilots, large language models (LLMs), and AI agents access and expose internal knowledge. The platform centers on a need-to-know model: rather than only filtering prompts, it detects when an AI system surfaces or infers information that a given user is not authorized to see. It treats this failure mode, known as knowledge oversharing, as an access-control problem rather than content moderation.

How it works

The platform builds role-based access policies and data labels, then runs simulation tests across user personas before an assistant goes live, probing many prompt patterns per persona to expose inference-based oversharing and anomalous knowledge access. A Shadow AI module finds unsanctioned tools, and the Kirin component extends the same controls to coding assistants and Model Context Protocol (MCP) servers. It then monitors continuously, flagging policy drift and new exposure as permissions and content change.

Credentials and traction

Knostic was named a 2025 Gartner Cool Vendor in AI Cybersecurity Governance and a 2025 SINET16 Innovator, and was a Top 10 finalist in the 2025 RSA Conference Innovation Sandbox. It won the 2024 Black Hat Startup Spotlight competition and was a 2024 RSA Conference Launch Pad finalist. Knostic is also featured across three categories in the Cloud Security Alliance Agentic AI Security Innovator Market Map. It serves security, governance, and engineering teams in regulated sectors including finance, healthcare, energy, and government.

Key Capabilities

mapped to solution categories
LLM Security

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

Enforces document-level access at retrieval time so a user receives only context they are authorized to see, filtering before the vector search, after retrieval, or both.

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

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.

Secures AI coding assistants and their Model Context Protocol connections against unsafe actions, data exposure and supply-chain risks.

AI Security Posture Management (AISPM)

Detects sensitive or regulated data in AI training, fine-tuning, or third-party LLM flows without appropriate controls, such as unencrypted PII in inputs or PHI sent to external APIs.

Assesses the identities and service accounts that AI models, pipelines, and agents use, flagging over-permissioned non-human identities and access paths that violate least privilege. Reports identity risk as a posture finding, distinct from enforcing access policies at the model API at runtime.

Automatically discovers AI models, LLM API connections, ML pipelines, and AI-enabled SaaS applications in use across the organization, including those deployed without IT authorization.
