Problem
Many modern applications struggle with authentication and authorization solutions that are either slow, vulnerable to memory‑related bugs, or lack easy migration paths from existing providers. Additionally, credential‑stuffing attacks remain a major threat because developers often cannot quickly verify whether user passwords have been exposed in large‑scale data breaches.
Solution
Signeen offers a suite of Rust‑based security services designed for high performance and memory safety. The Signeen Express server provides an Auth0‑compatible API, enabling organizations to replace or augment existing Auth0 integrations without code changes and to deploy the service in private‑cloud or on‑prem single‑tenant environments. Signeen Iris continuously checks user passwords against a database of over 2.5 billion breached password signatures, allowing applications to block compromised credentials in real time and meet NIST recommendations. Together, these components deliver low‑latency authentication, robust authorization, and proactive breach detection for modern software stacks.
Target Audience
Target customers are developers and security teams building web, mobile, or API‑driven applications that require fast, secure authentication and need to protect users from credential‑stuffing attacks, particularly those operating in regulated or private‑cloud environments.
