Plain-language summary

Knowing in advance which authorities you may need to notify or call on — regulators, law enforcement, emergency services — keeping their details and reporting channels current, and deciding who contacts them, when and how.

What the clause is really asking

Mid-incident is no time to find out who the regulator is and what they need. This control asks you to know which authorities matter to you and keep the lines to them open: identify them, keep their contact details and reporting channels current, and decide who contacts them, when and how. In South Africa the list usually starts with the Information Regulator, because POPIA section 22 requires notification of a security compromise involving personal information as soon as reasonably possible after discovery, and those notifications go through the Regulator's eServices portal. Add SAPS for cybercrime, fraud and theft — and check whether the Cybercrimes Act's reporting duties apply to your sector — and your sector regulator: the FSCA or the Prudential Authority for financial institutions under Joint Standard 2 of 2024, whose suppliers are often bound into those notification timelines by contract. Emergency services and utilities belong on the list for physical incidents. The common misunderstanding is that a phone list is enough; the control is about knowing your obligations and having access ready.

What auditors look for

Auditors ask for the list of authorities and check it is current — they may look up a number or two. They ask who is authorised to contact each authority and whether that person has what they need, such as a working eServices portal login for the Information Regulator. They trace a past incident or a tabletop exercise to see whether a notification decision was made and recorded, including a decision not to notify. For suppliers to financial-sector clients they ask how contractual incident-notification timelines are met. They check the contacts are linked from the incident response plan. The hard question: if personal information leaked this afternoon, who would notify the Regulator, and how?

Typical evidence

Register of relevant authorities with contact details, reporting channels and triggers for contact; named persons authorised to contact each; confirmed Information Regulator eServices portal access; incident response plan linked to the register; records of past notifications or decisions not to notify; tabletop exercise records; contractual notification obligations to regulated clients; register review dates.

How to comply — recommendations

Build a one-page authorities register: the Information Regulator, SAPS (local station and the cybercrime reporting route), your sector regulator, emergency services, municipal utilities and any client-imposed notification duties. For each, record when you must or would make contact, the deadline, the channel and the authorised person. Set up the Information Officer's access to the Information Regulator's eServices portal now and confirm the login works. Link the register to the incident response plan and add a notification decision step with the reason recorded. Run a tabletop exercise once a year that ends in a mock notification. Check every contact detail at least annually and after any regulatory change.

Common nonconformities

No list of relevant authorities, or one with outdated contacts; nobody authorised to notify the Information Regulator; no working access to the Regulator's eServices portal; incident plan silent on regulatory notification; past personal information breaches with no notification decision recorded; contractual notification duties to regulated clients unknown to the incident team; register never reviewed.
