Enterprise security specialists since 2004 with a focus on PKI, SSL, and cryptography.
Our journey began in 2004, when Phil Ratcliffe founded Red Kestrel Consulting. Building on early success, the company was incorporated as Red Kestrel Consulting Limited in 2007 to better serve a growing global client base.
Today, Red Kestrel is both a trusted security partner and a specialist product company. For over 15 years, our product CertAlert has helped businesses avoid SSL failures—before they impact operations. Alongside this, we've developed a range of free online PKI tools used by professionals worldwide, reflecting our commitment to practical, accessible security innovation.
Most recently, we released SslDecoder, an offline CSR and certificate decoder designed for high-security and air-gapped environments. The application is built upon our deep PKI expertise—experience that dates back to 1999 and includes contributions to critical PKI projects for major banks, government agencies, and global vendors. As the creator of one of the internet's original certificate decoders in 2007, Red Kestrel continues to engineer solutions that meet today's demands for enterprise privacy, compliance, and control.
