The SEC’s cybersecurity guidance connects knowledge of a significant incident to existing insider-trading restrictions. It does not make every breach automatically material, set a universal waiting period, or create a new rule for 2026.
When breach information can prevent you from trading
The SEC’s 2018 Commission Statement and Guidance on Public Company Cybersecurity Disclosures says directors, officers and other corporate insiders must not trade a public company’s securities while possessing material nonpublic information. The Commission notes that this information may include knowledge of a significant cybersecurity incident experienced by the company.
That warning is not a rule that every security incident bars every insider from trading. The relevant question is whether the information is material and nonpublic, whether you are aware of it when trading, and whether the applicable insider-trading rule and duty reach you. A company’s internal trading restrictions may also apply independently.
Is a breach material nonpublic information?
Not automatically. The SEC says cybersecurity risks and incidents may be material nonpublic information; the label “breach” alone does not decide the issue. Materiality depends on the circumstances and the information known about the incident, including its facts and ramifications. The SEC guidance does not supply a universal threshold that turns every incident into material information.

Information is nonpublic when it has not been made public. An incident may be under investigation while the company determines what happened and what it means. Do not assume that limited disclosure, rumors, or the fact that some details have become public means all material information about the incident is public.
What the SEC asks companies to do
The 2018 guidance addresses both insider-trading law and company controls. It urges companies to maintain policies and procedures designed to prevent trading between discovering a cybersecurity incident and publicly disclosing it, and to ensure timely disclosure of related material nonpublic information.
It also says that while a company investigates and assesses a significant incident and determines its facts, ramifications and materiality, it should consider whether and when trading restrictions are appropriate. This is guidance to companies, not a fixed calendar-based trading window imposed on every company. Internal blackout policies can be stricter or operate on their own schedule.
When can insiders trade after an announcement?
The cited SEC materials do not establish a universal number of days to wait after a breach announcement. Public disclosure does not necessarily mean that every relevant fact is public or that an employer’s blackout has ended. A person with actual inside information should check with the company’s securities-compliance contact or qualified counsel rather than infer a safe trading date from the announcement alone.

Does a Rule 10b5-1 plan let you sell?
Not as a blanket exemption. The SEC’s 2022 final rule on insider-trading arrangements explains that, subject to affirmative defenses, a trade is on the basis of material nonpublic information if the person was aware of that information when trading. A qualifying pre-existing written trading arrangement may provide an affirmative defense, but only if it satisfies the rule’s detailed conditions.
Among those conditions, the arrangement must be entered into before the person becomes aware of the material nonpublic information and must constrain the person’s subsequent ability to influence the trade. Creating or changing a plan after learning material nonpublic information does not make an immediate sale permissible. Whether a particular plan qualifies is a legal and fact-specific question.

- Materiality: Is the information significant in the circumstances, rather than merely information that a breach occurred?
- Public status: Has the relevant material information actually become public?
- Awareness: Are you aware of that information when the trade would occur?
- Applicable limits: Do insider-trading duties, a company blackout, or another internal restriction apply?
- Any plan defense: Is there a pre-existing arrangement that meets Rule 10b5-1’s requirements, rather than a plan adopted after learning the information?
If you possess nonpublic information about a potentially significant incident, do not treat uncertainty about materiality or timing as permission to trade. Get direction from your company’s securities-compliance contact or qualified counsel before acting.
