Operational guidance, not legal advice. This page distills named public sources (regulator guidance and industry practice).

Who must be notified after a data breach?

Last verified

Supervisory authorities, CSIRTs, affected individuals, customers, law enforcement, payment brands, and insurers are different recipient classes. Each is a legal requirement, a contractual obligation, or best practice only when it applies. This map is not legal advice and does not start a clock.

Recipient-class map, last verified 7 September 2026 against Regulation (EU) 2016/679 Articles 33–34, HIPAA 45 CFR §§164.406–408, PCI DSS v4.0.1 Requirement 12.10.1, Directive (EU) 2022/2555 Article 23, and Form 8-K Item 1.05. It is not legal advice, not YOUR notice list, and not a substitute for counsel.

This is a recipient-class map, not YOUR notice list

Audience: an incident commander, CISO, or counsel who needs a map of every notifiable party class so a required recipient is not missed. This page is not legal advice. It does not start a clock. Reading it does not start a clock. It does not name YOUR recipients. Counsel names the actual authorities, CSIRTs, people, customers, brands, and carriers on YOUR facts.

Recipient classes are not interchangeable. A GDPR Article 33 notice to a supervisory authority is not an Article 34 communication to a data subject, not a NIS2 Article 23 notification to a CSIRT, not a Form 8-K Item 1.05, not a PCI DSS payment-brand notice, and not an insurer claim notice. Filing one never discharges the others. Last verified 7 September 2026. Not legal advice.

  • A legal requirement applies only if the cited instrument applies to YOUR facts. Mapping a class is not a determination that you must notify that class.
  • A contractual obligation is YOUR contract, DPA, acquiring agreement, or policy — not 'the law'. This page does not interpret YOUR contract or YOUR policy.
  • Best practice is regulator guidance or operational practice. It is not a statute. Do not collapse PCI DSS or an insurer panel into 'the law'.
  • The who-to-call page on this site is a calling order (commander, counsel, insurer, DFIR). This page is the notification-duty map, not a call tree.
  • The regulator-customer-individual page on this site is the three-stream comparison. The GDPR breach-notification guide on this site is the jurisdiction treatment of Articles 33–34.

Checklist of recipient classes for the commander

Print the recipient table. Walk every class with counsel. A yes on one class does not skip the others. This is a question list, not a filing, and not YOUR notice list. The who-to-call page on this site is the calling order. The reporting-deadlines page on this site is the statute table of clocks. The do-I-have-to-report page on this site is the class map. The reporting-decision-tree page on this site is the branching tree. The regulator-customer-individual page on this site is the three-stream comparison. The prepare-regulatory-report page on this site is the field checklist. The supporting-evidence page on this site is the evidentiary record. The document-your-decision page on this site is the decision record.

  • Supervisory authority / regulator — does GDPR Article 33, HIPAA §164.408, Item 1.05, or another named supervisor apply? Counsel names the actual authority. This page does not.
  • Sector CSIRT — does NIS2 Article 23 (or another CSIRT duty, including CRA Article 14 if it applies) apply? A CISA report is not that filing.
  • Affected individuals — does GDPR Article 34 or HIPAA §164.404 (and §164.406 media, if the 500-resident test is met) apply? Article 34 is not Article 33.
  • Customers / controllers — are you a processor (GDPR Article 33(2)), a business associate (HIPAA §164.410), or a NIS2 entity that must notify recipients of services? Then read YOUR DPA / MSA as well.
  • Law enforcement — is there a duty on YOUR facts, or only the FTC/NIST practice of considering a call? Immediate danger is 911 first.
  • Payment brands and acquirers — PCI DSS v4.0.1 Requirement 12.10.1 is a standard, not a statute. Read YOUR acquiring agreement. This page does not rank brands.
  • Cyber-insurer — read YOUR notice clause. This page does not interpret the policy and does not rank carriers.
  • Who is authorised to send a notice, and who is not. A named human sends it. The product does not. This map does not send a notice and does not start a clock.

Glossary

These are teaching labels for this page. They are not legal conclusions about YOUR facts.

Terms used on this page (teaching labels — not a determination)
TermHow this page uses it
Recipient classA kind of notifiable party (regulator, CSIRT, individual, customer, law enforcement, payment brand, insurer). Not the named addressee on YOUR facts. Counsel names those.
Legal requirementA duty in a cited statute or regulation, only if that instrument applies. Not PCI DSS, and not YOUR policy.
Contractual obligationA duty in YOUR contract, acquiring agreement, or insurance policy. Includes PCI DSS v4.0.1 Requirement 12.10.1 as a standard given force by those contracts.
Best practiceRegulator guidance or operational handling (FTC guide, NIST SP 800-61r3 (April 2025 current final; it superseded SP 800-61r2), voluntary CSIRT sharing). Not a statute.
Supervisory authorityGDPR Article 33(1)'s recipient, competent under Article 55. Not a CSIRT, not the SEC, not HHS, and not a payment brand.
CSIRTNIS2 Article 23's computer-security incident-response team (or the competent authority where applicable). CRA Article 14 uses the CSIRT designated as coordinator plus ENISA — a different instrument.
Processor → controllerGDPR Article 33(2). The processor notifies the controller. That is not the controller's Article 33(1) notice to the supervisory authority.
PCI DSS v4.0.1A payment-card industry standard, not a statute. Requirement 12.10.1 requires the IRP to include notification of payment brands and acquirers, at a minimum.

Where this shows up in ShipReady Metrics

The signed-in app does not send notices, does not name YOUR recipients, does not interpret YOUR policy, and does not start a clock. None of the surfaces below is a notification, a recipient list, or an instruction to submit a filing.

If you already have a session: signed-in app → Compliance → CRA reporting tracks the Article 14 24-hour / 72-hour / 14-day ladder from recorded awareness for findings the organization has classified as CRA-in-scope. That is a product tracker for a clock the organization already recorded. It is not a notice to a CSIRT, not a determination that CRA applies, and a named human still submits.

The obligation map lists frameworks the organization has marked in-scope. That mark is not a recipient list, not a legal opinion that a notification duty applies, and not a list of addressees. signed-in app → Compliance → Questionnaires drafts answers to customer security questions from recorded posture; it is not a notification channel and does not send a customer, individual, regulator, CSIRT, payment-brand, or insurer notice. The cyber risk register lives under Security. None of those surfaces files a GDPR Article 33 or 34 notice, a NIS2 Article 23 notification, a HIPAA §164.404 / §164.406 / §164.408 notice, a Form 8-K Item 1.05, a PCI brand notice, or an insurer claim notice.

Primary sources (last verified 7 September 2026)

Every regulatory and standards claim on this page is taken from one of these. If a later revision of a source changes the rule, the date above is how you can see we have not re-checked yet.

Regulation (EU) 2016/679 Articles 33 and 34 are legal requirements only when GDPR applies. HIPAA 45 CFR §§164.406 and 164.408 (media; Secretary) sit with §164.404 (individuals) and §164.410 (business associate) — legal requirements only when HIPAA applies. Directive (EU) 2022/2555 Article 23 is a legal requirement only as transposed and only if you are an in-scope essential or important entity. Form 8-K Item 1.05 and 17 CFR 229.106 are securities-law disclosure, only if you are a registrant and the incident is determined material. PCI DSS v4.0.1 Requirement 12.10.1 is a payment-card standard published by PCI SSC, not a statute; the full text is in the PCI SSC Document Library (licence terms apply). The FTC Data Breach Response guide and NIST SP 800-61r2 are guidance. These are examples of classes, not a complete world list. Not legal advice.
