High assurance is a term used to indicate a level of confidence in the security and reliability of a system or service. It is usually associated with important documents, processes, information systems, digital services and activities that require secure and resilient operations. From an organizational standpoint, it can mean everything from meeting applicable compliance issues and data protection requirements to developing user-friendly digital financial services that maintain accuracy and consistency when handling customer transactions. For businesses, achieving high assurance requires both strong technical capabilities as well as well-defined auditing, validation and documentation processes. It goes beyond basic security measures such as firewalls and antivirus software and requires careful evaluation to uncover potential risk points. Whether your organization operates in the public or private sectors, having high assurance is essential for building trust in your services and ensuring that your business processes are reliable, error-free and safe.
