SEC Cybersecurity Disclosure Readiness
The SEC cybersecurity disclosure rule took effect in late 2023 and applies to every public company, plus pre-IPO companies preparing their S-1. The rule is not abstract. It requires a four business day materiality determination process, 8-K current reports for material incidents, and annual 10-K disclosure of cybersecurity risk management, strategy, and board governance. Most organizations discover they are unprepared the first time an incident forces the question. Z Cyber builds the complete disclosure readiness program: materiality framework your counsel and audit committee can defend, incident response process that produces the disclosure-ready facts inside the four day window, and board governance that holds up in your 10-K. For pre-IPO companies, we build the same program so your S-1 disclosure language is defensible from day one of the public filing.

Our Process
Framework design
Build the materiality framework with your general counsel, CFO, and audit committee. Define thresholds, decision rights, and documentation standards.
Operationalize
Wire the framework into incident response, legal review, and disclosure controls. Validate with a full tabletop exercise that walks the four day clock.
Board governance
Update audit committee charters, establish reporting cadence, and produce the 10-K disclosure language your counsel and auditors can sign off on.
Operate and refine
Run the program continuously, refine based on real incidents and near misses, and support annual 10-K disclosure review.
Frequently Asked Questions
What does the SEC cybersecurity disclosure rule actually require?
Two things. First, Item 1.05 of Form 8-K requires current report disclosure of material cybersecurity incidents within four business days of materiality determination. Second, Regulation S-K Item 106 requires annual 10-K disclosure of your cybersecurity risk management processes, strategy, and board governance.
Who decides whether an incident is material?
Your organization does, typically through a designated group that includes the CISO or security leader, general counsel, CFO, and CEO. Z Cyber builds the materiality framework that this group uses and documents the decision process for audit defensibility.
Does this apply to pre-IPO companies?
Yes. Once you file an S-1 and become subject to Exchange Act reporting, the disclosure rule applies. Most pre-IPO companies build the program six to twelve months before filing so the S-1 disclosure language reflects an operating program, not promises.
How does this integrate with our existing incident response program?
We overlay the materiality and disclosure process on your existing IR plan. The operational IR process stays the same. What changes is the parallel materiality track that runs alongside containment and produces the disclosure-ready facts within four business days.
