wolfSSL develops security software for embedded systems, emphasizing speed, compact size, portability, and adherence to security standards. Its core offering is a performance-oriented TLS library engineered for standard, embedded, and RTOS environments, which has secured over 2 billion connections worldwide. The library is notably smaller than OpenSSL and provides a straightforward API along with an OpenSSL compatibility layer, plus support for certificate status checks, dual licensing, and compliance with FIPS 140-3 and post-quantum cryptography.

Based in Edmonds, Washington, wolfSSL operates with a mid-sized team and targets developers and organizations needing robust cryptography for embedded and RTOS-based deployments. In June 2026, the company announced PKIX, a pure Rust implementation of RFC 5280 X.509 certificate path validation.
