Kids Online Safety Act (KOSA)

Kids Online Safety Act (KOSA) is proposed United States legislation aimed at reducing online harms to children on covered platforms. It would require stronger safety settings and risk management around design features that may expose minors to harm. Organisations should follow the bill’s progress carefully and align youth protections, reporting, and content controls to its evolving requirements.

What KOSA Is Trying to Change

KOSA is proposed U.S. legislation that would require covered platforms to reduce youth harm through stronger safety settings, design risk management, reporting, and content controls. It is less about a single technical control than about making child-safety duties more explicit and enforceable.

For practitioners, the key shift is that platform design choices become regulatory and governance issues, not just product decisions. That means recommendation systems, default settings, discovery features, messaging pathways, and moderation workflows may all need to be examined through a minors-first safety lens.

Why KOSA Matters for Platform Design

KOSA matters because harms to children often emerge from ordinary product features that amplify exposure, contact, or compulsive use. The practical concern is not only obviously abusive content, but also how ranking, recommendations, nudges, persistence, and visibility settings can shape what minors encounter and how often.

That makes the bill relevant to product architecture, trust and safety, and compliance teams at the same time. A platform can have policies on paper yet still create unsafe outcomes if the defaults, friction, or moderation paths are poorly designed for younger users.

Youth Safety Controls and Operational Expectations

Implementation under a KOSA-like regime usually points toward stronger age-aware safety settings, faster reporting paths, better moderation escalation, and clearer control over high-risk interactions. Covered organisations would also need to demonstrate that safety choices are reviewed over time rather than treated as one-time policy statements.

That review is likely to touch both user-facing and back-end controls, including content classification, safety-by-default configuration, abuse reporting, and the governance process for changing sensitive product features. The Age Verification and Age Assurance Guide is a useful companion where age-sensitive access decisions are part of the compliance design.

Because platform features can evolve quickly, the most durable response is a repeatable safety review process that tracks how product changes affect minors. Teams should expect the compliance burden to sit across legal, product, security, and operations rather than inside one function.

How to Read KOSA as a Governance Signal

KOSA is best understood as a signal that youth safety expectations are becoming more specific and more operational. Even before final legislative details settle, organisations should treat it as a prompt to inventory child-facing experiences, assign clear ownership for youth protections, and document how reporting and content controls are validated.

For cross-functional teams, the main value is clarity: if a feature can increase exposure, contact, or harmful engagement for minors, it should be reviewed like a governed risk, not a purely discretionary product choice. That mindset helps teams adapt faster as the bill, related enforcement, and platform obligations continue to evolve.

Standards & Framework Alignment

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.

NIST CSF 2.0 sets the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.

Framework Control / Reference Relevance
ISO/IEC 27001:2022 A.5.31 — Legal, statutory, regulatory and contractual requirements KOSA is proposed U.S. legislation that creates legal obligations for covered platforms.
A.5.34 — Privacy and protection of PII Youth-safety design commonly intersects with collection and handling of minors' personal data.
A.8.25 — Secure development life cycle KOSA-driven safety changes often require product and platform control changes to be designed and tested safely.
Recommendation — Track KOSA obligations in your legal requirements register and map them to product and safety controls. Review minors' data handling and privacy notices against the safety features and reporting flows you operate. Embed youth-safety requirements into the development lifecycle before changing recommendations, defaults, or reporting.
NIST CSF 2.0 GV.OC-01 — Organizational Context KOSA affects organisational roles, covered services, and the child-safety context around platform operation.
GV.RM-01 — Risk Management Strategy KOSA requires ongoing risk treatment for design features that may expose minors to harm.
PR.AT-01 — Awareness and Training Teams need operational awareness of child-safety duties, reporting paths, and safer design expectations.
Recommendation — Define which services, audiences, and internal owners fall within your KOSA impact scope. Fold youth-harm scenarios into your risk strategy and review them as product features change. Train product, trust and safety, and support teams on the controls that protect minors.
