What “Reasonable Security” Means Under Federal Law For Modern Businesses
Many businesses believe that “reasonable security” is a vague or optional concept. Under United States federal law, it is not optional. Federal regulators expect businesses of all sizes to take reasonable steps to protect personal data based on the nature of their operations, the type of data they collect, and the risks involved.
As we move into 2026, federal agencies have made it clear that failing to implement reasonable security measures can lead to enforcement actions, penalties, and long-term compliance obligations. This article explains what reasonable security means under federal law, how regulators evaluate it, and what modern businesses are expected to do.
UNDERSTANDING “REASONABLE SECURITY” UNDER FEDERAL LAW
There is no single federal statute that defines reasonable security in one sentence. Instead, expectations come from federal laws, regulations, and enforcement actions, primarily led by the Federal Trade Commission.
Under the Federal Trade Commission Act, businesses may be held responsible for failing to provide reasonable security for personal data if that failure is considered an unfair practice.
The Federal Trade Commission has explained that reasonable security depends on the size and complexity of the business, the sensitivity of the data collected, and foreseeable risks.
WHY “REASONABLE SECURITY” MATTERS MORE IN 2026
Federal regulators no longer accept the idea that data breaches are unavoidable. Businesses are expected to anticipate common risks and take steps to prevent them before harm occurs.
The Federal Trade Commission has stated that companies must take proactive measures to protect personal data.
Reasonable security is now considered a baseline legal obligation, not a best practice or optional standard.
WHAT FACTORS DETERMINE “REASONABLE SECURITY”
Federal agencies evaluate reasonable security by considering several factors, including:
• The type of personal data collected
• The amount of data stored
• The potential harm to individuals if data is exposed
• The cost and availability of security measures
• Whether the business follows recognized industry standards
Security measures are expected to match the level of risk involved.
KEY ELEMENTS OF REASONABLE SECURITY FOR MODERN BUSINESSES
ACCESS CONTROLS
Businesses should limit access to personal data to employees and vendors who need it to perform their job responsibilities.
ENCRYPTION AND DATA PROTECTION
Sensitive personal data should be protected using encryption or comparable safeguards, especially when data is stored or transmitted.
REGULAR RISK ASSESSMENTS
Businesses are expected to identify foreseeable risks to personal data and update security measures as risks change.
VENDOR AND SERVICE PROVIDER OVERSIGHT
Companies remain responsible for personal data shared with third-party vendors and must take steps to ensure those vendors also maintain reasonable security.
HOW REASONABLE SECURITY APPLIES ACROSS INDUSTRIES
HEALTHCARE AND HEALTH TECHNOLOGY
Organizations that handle protected health information must comply with security requirements under the Health Insurance Portability and Accountability Act.
FINANCIAL SERVICES
Financial institutions are required to safeguard consumer financial information under the Gramm–Leach–Bliley Act.
TECHNOLOGY, SOFTWARE, AND ARTIFICIAL INTELLIGENCE
Technology companies must ensure their data security practices align with how they describe those practices publicly. Failure to do so may result in enforcement actions.
REAL-LIFE SCENARIO 1: SMALL E-COMMERCE BUSINESS
A small online retailer stores customer names, addresses, and payment information but does not update its systems or restrict employee access to customer data.
A cyber incident exposes thousands of customer records.
What went wrong:
The business failed to implement basic and reasonable security measures.
Possible consequences:
• Federal Trade Commission investigation
• Required security audits
• Civil penalties
• Loss of customer trust
REAL-LIFE SCENARIO 2: SOFTWARE COMPANY WITH MISLEADING SECURITY CLAIMS
A software company claims it uses “industry-leading security” but does not encrypt sensitive data or maintain proper internal controls.
What went wrong:
Misleading security claims may be considered deceptive under federal law.
Possible consequences:
• Enforcement action
• Mandatory changes to security practices
• Long-term compliance monitoring
• Reputational damage
WHY REASONABLE SECURITY PROTECTS ORDINARY PEOPLE
Reasonable security helps protect individuals from:
• Identity theft
• Financial fraud
• Exposure of sensitive health information
• Loss of privacy and control over personal data
Federal security expectations exist to reduce real-world harm, not just regulatory risk.
