About 1 Sequence Cyber

1 Sequence Cyber is a multi-disciplinary cybersecurity firm with QSA capabilities, security training, and consulting services delivered from offices in London, Singapore, and Sydney. The firm's breadth of services makes it a one-stop partner for organisations that need assessment, remediation, training, and ongoing security management.

1 Sequence is particularly valued for its training programmes, which go beyond standard PCI awareness to provide hands-on, role-specific security education. Their "PCI Champions" programme embeds compliance knowledge within client organisations, reducing dependence on external consultants.

The firm's QSA practice handles assessments from SAQ validation for small merchants through to complex ROC assessments for multinational service providers, with particular expertise in cloud-native and containerised payment environments.
