The SEC's new cyber disclosure rules aren't just a Wall Street problem.
If you do business with any publicly traded company, you are now inside their compliance perimeter. Most SMB owners don't realize it yet.
Here's what changed: the SEC now requires public companies to disclose material cybersecurity incidents within 4 business days and report on their security governance in every annual filing. That's the public company's burden. But when those companies start auditing their vendors' security posture, the pressure lands directly on you.
What this means in practice:
1. Vendor risk assessments are accelerating. Public companies need to demonstrate control over their supply chain. If you can't show basic security hygiene on paper, you risk losing contracts.
2. Four days is a brutal detection-to-disclosure timeline. It assumes the ability to detect an incident, scope it, confirm materiality, and notify within a week. Most SMBs have no incident response plan. That gap is now a contract liability.
3. Board-level accountability is now documented. When cyber governance appears in annual filings, boards ask harder questions of every vendor they rely on.
You don't need a full security team to get ahead of this. You need a clear incident response plan, documented security policies you can share, and answers ready for the vendor questionnaires that are coming.
The businesses that scramble to answer these questions mid-contract renewal lose business. The ones with answers ready win it.
If you're not sure where your security documentation stands, that's the first thing worth addressing.
It's just clarity on where you stand.
