INJECT.md provides a comprehensive prompt-injection audit service for large language model (LLM) applications, identifying vulnerabilities that arise from untrusted input data such as web pages, emails, PDFs, and tool responses. It offers a battery of 46 payloads across five attack classes to test and score the resistance of LLM endpoints, helping developers structurally harden their systems against prompt injection attacks that can lead to unauthorized data leaks or actions. - **Injection Payload Battery** — Runs 46 payloads across 5 attack classes to test LLM endpoint vulnerabilities. - **Scored Resistance Report** — Provides a detailed score and breakdown per attack class with pass/fail results. - **Remediation Guidance** — Includes a hardening playbook with structural fixes mapped to failed attack classes. - **Local Execution** — Runs scans locally to ensure API keys never leave the user's environment. - **Continuous Integration Integration** — Supports CI pipelines with non-zero exit on failure to gate deployments. - **Scheduled Re-testing** — Automates periodic re-runs to catch regressions and new attack classes. - **White-label Agency Reports** — Offers unlimited endpoints and clients with branded reports and API access. ## Who it is for and why **Who it is for:** Developers and security teams building and maintaining LLM applications **Problem it solves:** Prompt injection is a critical security risk for LLM applications where malicious instructions hidden in untrusted input can cause unauthorized data leaks or actions. Existing prompt-based protections are ineffective because injection attacks exploit the data the model reads, not just the prompt itself. **The solution:** INJECT.md runs a comprehensive battery of injection payloads against LLM endpoints to identify vulnerabilities, scores resistance per attack class, and provides detailed reports with remediation steps and a hardening playbook. It runs locally to keep keys secure and integrates into CI pipelines for continuous protection. **What makes it unique:** - Comprehensive 46-payload battery covering multiple injection attack classes - Structural approach focusing on architecture rather than prompt wording - Runs locally ensuring keys never leave the user's environment - Provides scored, detailed reports with remediation guidance and continuous updates ## Pricing - **Free scan** — $0/one-time: 8 payloads from the public subset, pass/fail summary, runs locally with no account or card required - **Audit report** — $69/one-time: Full battery of 46 payloads, scored HTML and JSON report, remediation guidance, 12 months corpus updates - **Re-test** — $39/month: Scheduled re-runs, CI gate, diff against last run, alert on new attack classes - **Agency** — $249/month: Unlimited endpoints and clients, white-label reports, API access, priority corpus requests ## Facts - **Official website:** https://inject.md/ - **Category:** [Cybersecurity](https://www.exitfounder.io/category/cybersecurity) - **Pricing:** subscription - **Business model:** saas - **Tags:** prompt injection, continuous integration, risk assessment, llm security, penetration testing, ai safety, Cybersecurity - **Technology:** Open Graph, Vercel Analytics, Vercel, Next.js, React - **Domain Rating:** 0 (Domain Rating by Ahrefs) - **Estimated monthly visits:** — - **MRR:** not verified - **Verification:** none yet - **Listed on ExitFounder:** 2026-09-19 - **Listing page:** https://www.exitfounder.io/startup/inject-md ## FAQ ### What is INJECT.md? Prompt-injection audit for LLM apps enhancing security ### Who is INJECT.md for? Developers and security teams building and maintaining LLM applications ### How much does INJECT.md cost? Free scan $0/one-time; Audit report $69/one-time; Re-test $39/month; Agency $249/month. ### Is INJECT.md verified? Not yet. The profile was generated from the official website; the founder can claim it at https://www.exitfounder.io/startup/inject-md/claim. ### What is prompt injection? Prompt injection is a security risk where malicious instructions hidden in untrusted input cause an LLM to perform unauthorized actions or leak secrets. ### How does INJECT.md protect my LLM app? It tests your endpoint with a battery of injection payloads, scores vulnerabilities, and provides remediation steps to structurally harden your system. ### Do I need to share my API keys? No, scans run locally on your machine, so your keys never leave your environment. ### What happens if my system fails the test? You receive a detailed report with ranked remediation guidance and a hardening playbook to fix vulnerabilities. ### Can I automate testing? Yes, INJECT.md integrates with CI pipelines to automatically gate deployments based on injection resistance. ### Are there alternatives to INJECT.md?
