Astra

Your AI agent reasons on safe tokens, acts on real data — never sees your PII

Astra is a security layer for AI agents that prevents sensitive data from ever reaching a language model. It tokenizes Protected Health Information (PHI), Payment Card Industry data (PCI), and Personally Identifiable Information (PII) before they enter the agent's context. The agent reasons on safe placeholder tokens, then Astra swaps them back for real values at execution time—so the LLM never actually sees a credit card number, SSN, or patient record. The integration is deliberately minimal: two lines of code, framework-agnostic, works with any agent stack. This matters because as AI agents get embedded into healthcare, fintech, and enterprise software, the question of what data flows through the model context is becoming a compliance and liability flashpoint. HIPAA, PCI-DSS, and GDPR all impose restrictions on where sensitive data can be processed and logged—and LLM APIs typically don't offer the data handling guarantees those regulations require. Astra is a new indie launch from founder Obed Mpaka, shipping on Product Hunt today. The approach is elegant: instead of trying to secure the model provider's infrastructure, constrain what reaches it in the first place. It's early-stage, but the problem it's solving is real and growing.

Panel Reviews

The Builder

Developer Perspective

Ship

“Two lines of code to keep PHI and PII out of your LLM context is a beautiful proposition. Anyone building agents in healthcare or fintech needs this kind of layer—compliance teams will stop blocking agent deployments if you can show the model never touches raw sensitive data.”

The Skeptic

Reality Check

Skip

“Brand new solo-founder launch with zero reviews and 13 followers. The tokenization concept is sound but the implementation needs serious auditing before you trust it with actual PHI in a HIPAA environment. 'Two lines of code' hiding complex security logic is exactly the kind of abstraction that creates false confidence.”

The Futurist

Big Picture

Ship

“The regulatory pressure on AI in healthcare and finance is only intensifying. Tools like Astra that create a clean data boundary between your sensitive infrastructure and third-party LLM APIs are going to be essential plumbing for enterprise AI adoption. This category will be huge.”

“Not directly relevant to creative workflows, but the trust dimension matters here. If AI tools that handle my client data could accidentally expose PII through model contexts, I'd want exactly this kind of protection. Watch this one—if it matures, it's infrastructure for the whole creative economy.”
