From employees to autonomous agents

AI creates another path for data exposure and untrusted instructions. Prompt Security provides visibility into AI tools and policy enforcement across their inputs, outputs and interactions with business systems.

Employees

Discover AI tools including shadow AI and control the sharing of sensitive information.

Developers

Protect secrets and proprietary code when working with AI coding assistants.

Homegrown AI apps

Runtime controls against prompt injection and inappropriate data exposure.

Agents and MCP

Visibility into agents, permissions and interactions with tools and MCP servers.

Prompt Security and Purple AI serve different needs

Prompt Security protects AI usage across the organisation. Purple AI helps security analysts investigate events. Selecting one product does not automatically grant a licence to the other.

Start with an inventory of AI usage

Together we assess AI services, developer tools, homegrown apps, sensitive data and permitted agent actions. We define a pilot and policies that can be tested against your actual workflows.

  • Define employees, developers, applications and agents in scope.
  • Verify SaaS or self-hosted deployment and supported integrations.
  • Test detection, blocking, data redaction and audit trails.
