Sixscape Communications
Sixscape Communications is a Singapore-based cybersecurity vendor specializing in Public Key Infrastructure (PKI) automation and post-quantum readiness. Founded in 2014 by cryptography veteran Lawrence Hughes, the company builds digital certificate-based products for secure email (S/MIME), password-less authentication, IoT device identity and unified communications. Its patented Identity Registration Protocol (IRP), assigned IANA port 4604, automates the request, issuance and management of X.509 certificates so enterprises can deploy trusted digital identities in seconds rather than weeks. Sixscape sells through a 100% partner-centric model spanning system integrators, resellers and certificate authorities, and positions its IDcentral platform for certificate lifecycle management and cryptographic posture management in a market bracing for shorter TLS certificate lifespans and the migration to quantum-safe algorithms.
