ISO 27001 programme
Control mapping, evidence packs, and the gap work that has to finish before a formal audit.
Fractional Advisory Board
Samuel Okonkwo, CISA
Independent Advisor — Information Security. ISO 27001 lead auditor. He advises the ISMS behind Cyber Essentials and the formal audit targeted for Q4 2026.
Role
Samuel is the board’s independent security advisor. He does not operate the platform and he is not the certifying body. He reviews whether Inject Group Ltd can evidence the controls a CISO will ask for — access, logging, encryption, air-gap, and the vendor questionnaire issued under NDA.
Background
He is a CISA-certified practitioner and ISO 27001:2022 lead auditor who has assessed ISMS programmes for payments, fintech, and public-sector technology vendors. His independent practice covers control design for on-premise and air-gapped deployments — the posture Nexus states on the security notice and compliance pages.
Inject Group Ltd holds Cyber Essentials. An ISO 27001 formal audit is in progress, target Q4 2026. Samuel advises that programme; he does not issue the certificate.
What he advises Nexus on
On-premise and air-gap
How identity, logging, and key management should look when the stack sits inside a central-bank network.
NDA security pack
Whether the confidential questionnaire is complete enough for a CISO due-diligence reviewer. See resources.
Engagement
Independent retainer. Fractional. He is not a statutory director — those are listed at Companies House 16282987.
