Regulatory change can be a strategic business driver or a roadblock. Whether you’re a vendor, service provider, or business with downstream customers, you’re increasingly subject to tighter cybersecurity and privacy requirements. As we look toward 2026, three regulatory trends stand out: the Cybersecurity Maturity Model Certification (CMMC), new rules from the U.S. Securities and Exchange Commission (SEC), and a wave of evolving state privacy laws. Understanding each of these (and the business implications) will help you plan proactively and gain a competitive edge.

1. CMMC: For the Defense Supply Chain
What is it?
The Cybersecurity Maturity Model Certification (CMMC) is a framework developed by the U.S. Department of Defense (DoD) that sets cybersecurity standards for organizations that handle sensitive government information.
Key terms:
FCI = Federal Contract Information (non-public information provided by or created for the government)
CUI = Controlled Unclassified Information (information that requires safeguarding or dissemination controls)
CMMC has defined “levels” of maturity. Higher levels mean more rigorous controls.
Why does it matter to your business?
-
If you supply the DoD (directly or as a subcontractor) you will increasingly see CMMC compliance in the contract language. Without a required CMMC level, you may not be eligible to bid or win contracts.
-
But the impact goes wider: even if you’re not part of the defense supply chain, many private-sector companies use CMMC readiness as a competitive differentiator (e.g., if they serve government contractors).
-
From a cost perspective: businesses that delay preparation may face higher costs, rushed implementation, and missed opportunities.
-
It forces a shift from “we’ll fix this once we get an RFP” to “this is how we operate continuously.”
Key 2026-Relevant Milestones
-
As of 10 November 2025, the DoD’s final rule via 48 CFR becomes effective, meaning contracts can require CMMC Level 1 or Level 2.
-
By 31 October 2026, new DoD contracts involving FCI or CUI will mandate a CMMC certification. Without it, organizations may not bid.
-
After 2026, the standard becomes even more pervasive across suppliers and subcontractors.
Business Takeaways:
-
If you play in the defense marketplace, treat CMMC readiness as a business enabler and not just a technical checkbox.
-
Map your contracts now: Do you handle FCI or CUI? What level are you likely to need? What gaps do you have?
-
If you serve customers who are defense contractors, your own compliance posture (or ability to support your customers’ compliance) can become a selling point.
-
Budget ahead: compliance isn’t “once and done” but ongoing maintenance.
2. SEC Cybersecurity Rules: Public Company and Market-Facing Impacts
What is it?
The U.S. Securities and Exchange Commission (SEC) has finalized or is finalizing rules that require publicly traded companies (among others) to disclose material cybersecurity incidents, risk management practices, and board oversight of cybersecurity.
Why it Matters to Your Business
-
Although the rules are targeted at larger public companies, the ripple effects touch private companies, vendors, and service providers because of the supply-chain, contractual, and reputational linkages.
-
Customers and investors increasingly expect to see robust cybersecurity disclosures and transparent practices. Being able to demonstrate those helps build trust and mitigates risk.
-
Non-compliance or inadequate practices can lead to enforcement action, reputational damage, and litigation risk.
Practical Business Drivers
-
Even if you’re private, think: could a major customer or investor ask about your cybersecurity posture? Do you have aligned contracts and vendor oversight policies?
-
Risk-management questions: Is there a board-level or leadership recognition of cybersecurity as a business risk (not just an IT issue)?
-
Incident readiness: Do you have documented plans and roles for how you’d respond to a breach, or how you’d notify key stakeholders? These are the kinds of expectations that SEC-driven practices embed.
3. State Privacy Laws: 2026 Is a Big Year
In the absence of a single federal privacy law in the U.S., many states have enacted or are enacting comprehensive privacy laws that regulate how businesses collect, use, share, and protect personal data.
-
The California Consumer Privacy Act (CCPA) and its amendment the California Privacy Rights Act (CPRA).
-
States like Montana, Kentucky, Oregon, etc., have either passed laws which become effective in 2026 or amended laws with new obligations.
Why it Matters for Business
-
If you collect or process personal data of residents in those states, or do business there, you may fall under these laws, even if you’re located elsewhere.
-
Non-compliance may mean fines, enforcement actions, contractual liability, or being locked out of doing business in certain states.
-
Because each state law has differences (definitions, thresholds, rights for consumers), operating across states creates complexity, and this often becomes part of vendor/customer due diligence.
-
The trend is toward stricter enforcement, focus on children’s data, biometrics, profiling, and AI-driven decision-making.
Business-focused Takeaways
-
Conduct a data-map: what personal information do you collect, where does it come from, where is it stored, who do you share it with?
-
Review your contracts and vendor arrangements: upstream and downstream. Customers often demand clauses reflecting state privacy laws.
-
Build a plan to handle consumer rights requests (access, deletion, correction) and the mechanics of tracking and responding.
-
Recognize that privacy compliance isn’t just a legal cost. It can be a business differentiator (customer trust, brand reputation) or a blocker from loss of market access.
4. Putting it All Together
The Shift from “One-and-Done” to “Business as Usual”
Traditionally, many organizations treated cybersecurity and privacy compliance as “projects”. Ticking the box to meet a requirement and moving on. But as experts point out, the 2025-2026 timeframe marks a transition: compliance becomes embedded in how the business runs every day.
Think: continuous monitoring, recurring attestations, supplier and customer readiness, integrated governance, not just IT controls.
Why This Matters
-
Competitive advantage: customers and partners increasingly expect their vendors to be compliant because they themselves face regulatory, market and reputational risks.
-
Risk mitigation: regulatory action, data breach fallout, contract losses are all business risks—not just IT risks.
-
Cost control: preparing early gives you more options for budget, process design, vendor alignment, and avoids emergency spending or missed business opportunities.
-
Customer-facing implications: if your business supports customers (for example, SaaS, managed services, B2B), you may need to show your compliance posture in sales conversations, bid processes, or contract negotiations.
5. Common Misconceptions & Pitfalls
“We don’t do government work, so CMMC doesn’t apply.” → True, you may not directly need CMMC, but if you serve someone who does, or your customer base cares, non-readiness could be a barrier.
“We’re small so we’re exempt.” → Many state privacy laws apply based on data volume, types of processing, or revenue thresholds, not just company size.
“We’ll wait until the deadline.” → Waiting tends to increase cost, risk and stress. Early movers often gain competitive edge.
“It’s an IT project.” → It’s not just IT. It’s about business processes, culture, contracts, vendor relationships, customer trust.
Key Actions for 2026 Compliance Readiness
-
Governance & leadership buy-in | Make sure board/leadership treats cyber and privacy as business issues.
-
Data inventory & supply-chain visibility | Know what data you handle (yours and customers’), who you share it with, who shares it with you.
-
Contract review & vendor management | Update vendor contracts, customer contracts, service-level agreements to reflect new regulatory obligations.
-
Incident response & disclosure readiness | Have a documented plan for cyber incidents, know who does what, when, and how to escalate.
-
Privacy-rights process | Build the process for consumer rights under state laws where you operate; monitor changes in new states adopting laws.
-
Communicate value | Use compliance readiness as part of your value proposition: “We’ve aligned with CMMC, we meet XYZ privacy law, we’re ready for SEC-style disclosure expectations.”
-
Budget & timeline planning | Don’t wait. For example, if you’re targeting DoD contracts, CMMC certification will likely require months of preparation.
Conclusion
As we head toward 2026, the regulatory environment for cybersecurity and privacy is shifting from optional to inevitable. Whether it’s the CMMC for defense-industry work, SEC cybersecurity disclosure expectations, or the expanding patchwork of state privacy laws, the common theme is this: compliance readiness is a business imperative.
For businesses, that means moving from reactive check-boxes to proactive strategy: aligning governance, data-flows, vendor ecosystems, contract language, and customer expectations.
