Independent Assurance, Measurable Confidence.
Assurance is not just about compliance, it is about confidence. With cyber threats evolving, regulatory expectations increasing, and supply chains growing more complex, organisations need an independent, expert view that validates decisions, identifies blind spots, and ensures investments are delivering measurable security outcomes.
Nine23’s Assurance as a Service gives you this confidence. Acting as a trusted partner, we provide continuous oversight and validation across your cyber security strategy, projects, and supply chain – proportionate to your risk appetite and business objectives.
Independent Oversight & Validation
We review, test and assure cyber initiatives, from tooling implementations to automation playbooks, giving leadership confidence that security controls are effective, appropriate, and aligned with your risk appetite.
Business-Aligned Assurance
We go beyond technical compliance. Our assurance activities ensure cyber security initiatives support organisational objectives, provide value for money, and are delivered in line with public sector governance such as the Technology Code of Practice and Treasury Green Book.
Supply Chain Assurance
We help you build trust in your suppliers through targeted audit and assurance. We map your supply chain, assess critical risks, and implement processes and technologies to manage them. Our services include technical monitoring, formal audits, and an “audit the auditor” model for transparency. Working closely with your teams and partners, we help identify and mitigate supply chain risks to protect all parties.
Flexible Engagement Models
Whether embedded within your projects, delivered as an independent audit, or sustained as a managed assurance service, Nine23 tailors delivery to meet your needs. We can work within your environment, or leverage our secure UK sovereign private cloud to host, test and validate services before deployment.
