By now, most South African organisations are aware of the Protection of Personal Information Act (POPIA) and have taken steps to address its requirements. However, being aware of the law or having policies in place does not necessarily mean that privacy is being managed effectively. This becomes a challenge when clients, partners, or regulators ask organisations to show how personal information is being handled.
ISO 27701 addresses this gap by extending ISO 27001 to include privacy-specific controls and providing a structured way to manage Personally Identifiable Information (PII) throughout its lifecycle. This gives organisations a way to demonstrate how privacy is managed, rather than relying solely on internal policies or self-assessments.
More than just awareness
Organisations often assume that addressing POPIA requirements is sufficient to demonstrate privacy compliance. However, when privacy processes are not clearly defined, consistently applied, or formally governed, gaps can appear, and risk can be introduced. One reason for this is that while POPIA sets out clear requirements, it does not define how those requirements should be implemented and managed. It also does not include a formal certification process, which makes it difficult for organisations to show that their privacy controls are in place and being applied consistently.
ISO 27701 addresses this by building on ISO 27001 and extending the existing Information Security Management System (ISMS) to include privacy. This requires organisations to define how personal information is managed, assign responsibility, and implement controls, while also ensuring that these processes are reviewed and maintained on an ongoing basis.
Raising the standard
For businesses with international clients, privacy requirements extend beyond POPIA, adding another layer of complexity. Clients in the European Union (EU), for example, require alignment with regulations such as the General Data Protection Regulation (GDPR) as part of onboarding or supplier assessments.
ISO 27701 helps address this by providing a single framework that aligns with both POPIA and GDPR. It allows organisations to manage privacy requirements across different jurisdictions without treating each one separately.
This is increasingly relevant for South African businesses that operate internationally or are part of global supply chains, where organisations are required to demonstrate that privacy is managed in line with a recognised standard, rather than relying on local compliance alone.
Gaps in demonstrating compliance
Meeting local and international privacy requirements is only part of the challenge. Businesses also need to be able to prove that their controls are being applied effectively, which is often where the problem lies. For example, organisations may collect and store personal information securely, but may not have clear processes in place for how long it is retained, when it should be deleted, or how that deletion is verified.
These gaps create both regulatory and reputational risk. It is not enough to state that data will be protected or deleted. Organisations need to demonstrate how these processes are defined, followed, and reviewed over time.
ISO 27701 helps organisations address these gaps directly, since the standard requires exactly this level of detail to demonstrate compliance with data privacy regulations. It focuses on how privacy is managed on an ongoing basis, and whether organisations can provide evidence that their controls are working as intended.
Like ISO 27001, ISO 27701 also requires maintenance. Organisations are expected to monitor, review, and update their controls and demonstrate this over time. This is where cybersecurity and compliance specialists are often needed to support implementation and ensure that privacy practices meet external requirements.
For organisations that already have ISO 27001 in place, this means expanding current processes to address how personal information is handled, rather than starting from scratch. Aligning with the standard allows organisations to demonstrate to clients, partners, and regulators how personal information is managed. It requires clearly defined roles, responsibilities, and controls, as well as evidence that these controls are applied consistently.
