Wardstone
Wardstone is an LLM security API that sits between applications and language model providers, scanning inputs and outputs for threats across four categories in a single call: prompt attacks, content violations, data leakage, and unknown links.
It detects jailbreaks, prompt injections, harmful content (hate, violence, self-harm), PII (SSNs, credit cards, emails, phone numbers), and suspicious URLs. Each response returns risk bands per category with sub-30ms latency.
Works with any LLM provider. REST API with SDKs for TypeScript, Python, Go, Ruby, PHP, Java, and C#. Free tier at 10,000 calls/month, no credit card required. Includes a browser-based playground for testing.

Plurilock AI PromptGuard
Plurilock AI PromptGuard is a new, patent-pending security tool designed to protect companies against data leaks while their employees use generative AI platforms like ChatGPT.
Unlike other solutions to the generative AI data leakage problem, PromptGuard doesn't block AI use or individual AI prompts. Instead, PromptGuard relies on a mature DLP engine to detect sensitive data in prompts and anonymize it before it is sent to the AI platform. When the AI platform returns an answer, PromptGuard restores the original references before showing them to the user.
This preserves the workflow and query flow of AI, enabling users to productively use it, while keeping sensitive data out of the AI platform's hands.
PromptGuard also provides a complete, bi-directional audit log of queries and replies for each user, enabling companies to create a compliance-friendly record of what was sent to AI, and what AI sent back.
