The AI firewall that understands compliance context
PromptLock launched on December 22, 2025 with 5 votes, #2,550 of 11,628 launches that month.
What it does
PromptLock is a single API that protects your AI apps from prompt injection attacks AND automatically redacts sensitive data based on compliance frameworks—HIPAA for healthcare, PCI-DSS for payments, GDPR for personal data. Most AI security tools make you choose: block attacks OR handle compliance. We do both in one call, under 100ms. Built for startups and developers in regulated industries who don't have months to build custom security pipelines or enterprise budgets for bloated solutions.
Protect your AI from jailbreaks, data leaks, and compliance violations — before they reach the LLM. HIPAA/GDPR/PCI compliant.

We also ship a red team suite and an autonomous agent that mutates attacks to find bypasses - you get a grade (A-F) and a GitHub Action that runs these tests on every PR. So you see where you're weak before you ship. Works with OpenAI, Anthropic,…

Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
