Yes. Specter and Guardian are independent components of the Hellgate Composable Payment Architecture. Specter provides real-time fraud intelligence and risk scoring. Guardian provides PCI-compliant card vaulting and tokenization. They integrate naturally when both are in use – Specter can read token-level signals from Guardian to improve scoring accuracy – but each can be deployed standalone or alongside your existing payment infrastructure.
