What this state lookup shows

Delaware fields are rendered from the verified state dataset only when the field exists. No deadline is inferred when the data does not state one.

6 Del. C. §§ 12B-102 to 12B-103 is the statute citation retained for this lookup, and the state page links to the official statute source when available.

Delaware requires Attorney General notice when a security breach affects more than 500 Delaware residents, and the Consumer Protection Unit provides online and fillable forms for Attorney General notice. The consumer trigger matters because the clock usually starts only after a legally meaningful incident analysis, not merely because an IT alert appeared.

The last verified date for this Delaware lookup is 2026-08-13. Use that date as a prompt to refresh counsel review before making a live notification decision.

How to use it during an incident

Start with containment and evidence preservation, then identify affected resident states and compare the shortest stated deadline first.

A practical incident file should record discovery time, encryption status, systems involved, affected consumer count, vendor involvement, and the person responsible for counsel review.

For Delaware, the WISP should say where the notification decision log lives, who contacts counsel, who checks the regulator portal, and who approves any consumer notice before it is sent.

This lookup pairs with the Incident Response Plan because the plan owns the workflow: intake, escalation, containment, preservation, notice analysis, communications, and final review.

How it fits the WISP

A WISP should not guess at state-law outcomes; it should make the breach-review path fast, documented, and source-linked.

Pair this lookup with the Delaware WISP requirements page so the firm's written program names the state-aware incident path before an event happens.

Policywright keeps the breach clock separate from the policy packet: the lookup tells you what to review, while the generated packet assigns owners, evidence records, remediation steps, and review cadence.

Not legal advice. A qualified lawyer should confirm whether the incident facts meet a statutory definition, whether substitute notice or regulator notice applies, and whether another state or federal rule changes the timeline.

FAQ

Is this Delaware lookup legal advice?

No. It is a source-linked lookup for incident planning and should be reviewed with qualified counsel before relying on it in a live notification decision.

What if affected residents live outside Delaware?

Use the multi-state lookup page and include every state where affected residents may live. The comparison table sorts selected states by the shortest stated deadline first.

Does this replace the FTC Safeguards Rule notice analysis?

No. State notice review is separate from the federal Safeguards Rule and 16 CFR 314.4(j) analysis. A serious incident file should preserve both review tracks.
