Cyber threat sharing helps critical-infrastructure organizations spot risks sooner and coordinate a response; transparency makes that cooperation useful by clarifying who is responsible, what each partner can do, and how information moves. It does not mean publishing sensitive operational details. Effective collaboration depends on controlled sharing, clear handling rules, and safeguards for privacy, civil liberties, and business confidentiality.
How does threat-information sharing help protect critical infrastructure?
Electricity, water, communications, transportation, healthcare, and other essential services depend on organizations that often operate different systems but face overlapping cyber risks. A threat seen by one operator may be relevant to another; timely, actionable exchange can help partners assess exposure and coordinate protective steps rather than respond in isolation.
U.S. federal policy has framed this as a partnership between government and infrastructure owners and operators. Executive Order 13636 (2013) states a policy of increasing the volume, timeliness, and quality of cyber threat information shared with private-sector entities. Executive Order 13691 (2015) explains the need for collaboration: “In order to address cyber threats to public health and safety, national security, and economic security of the United States, private companies, nonprofit organizations, executive departments and agencies (agencies), and other entities must be able to share information related to cybersecurity risks and incidents and collaborate to respond in as close to real time as possible.” The orders as reproduced in Title 6 of the U.S. Code describe policy goals, not a quantified guarantee that sharing will prevent an attack.
What does transparency mean in cyber defense?
In this context, transparency is most useful when it makes collaboration legible: partners understand one another’s roles, responsibilities, capabilities, authorities, and escalation routes. It is not a call to disclose vulnerabilities, network diagrams, incident details, or other sensitive operational information publicly.

In a December 5, 2023 report, CISA’s Cybersecurity Advisory Committee recommended that CISA develop an operational collaboration framework with this kind of role clarity. The recommendation envisioned a framework broad and flexible enough for all 16 critical-infrastructure sectors and subsectors, whose structures, priorities, and needs differ. It is a recommendation, not evidence that the framework was adopted or that it produced measured security outcomes. Read the committee’s report.
How can organizations share information without exposing sensitive data?
Sharing should be designed around purpose, audience, and handling—not treated as unrestricted publication. Executive Order 13691 encourages voluntary information-sharing organizations and calls for attention to contractual agreements, business processes, operating procedures, technical means, and privacy protections. The order’s text provides the policy context; organizations still need to determine what their own legal, contractual, and regulatory obligations require.
- Define the purpose and audience. Decide which partners need the information and what action it should enable.
- Limit unnecessary details. Share enough to make a report actionable while minimizing sensitive personal, business, or operational information that recipients do not need.
- Agree on handling rules. Clarify permitted use, onward sharing, retention, access, and escalation before an urgent incident arises.
- Make the route and responsibilities clear. Identify who can receive and validate a report, who can act on it, and how to reach the right decision-maker.
- Check protections and exceptions. Do not assume a voluntary submission is automatically confidential or exempt from every disclosure request; verify the governing statute and the channel’s terms.
What information can companies share with CISA?
Organizations can use appropriate channels to exchange cybersecurity-risk and incident information with government partners, but the legal treatment depends on what is submitted, to whom, for what purpose, and how the submission is made. Under 6 U.S.C. Chapter 1, Subchapter XVIII, protection applies to qualifying critical-infrastructure information voluntarily submitted to a covered federal agency when accompanied by the prescribed express statement and used for covered purposes. The statute also defines conditions and exceptions; it is not a blanket promise of secrecy or immunity for every disclosure. Consult the current statutory text and applicable submission instructions before sending sensitive material.
Voluntary sharing is also distinct from incident-reporting duties that may arise under other laws, regulations, contracts, or sector rules. The voluntary-sharing protections described here do not determine whether a separate reporting obligation applies.

Information Sharing and Analysis Centers (ISACs) and Information Sharing and Analysis Organizations (ISAOs) offer ways for organizations to exchange information and collaborate around a sector, subsector, region, or other shared interest. Executive Order 13691 encourages voluntary organizations that may have public-sector, private-sector, or mixed membership, and calls for ongoing collaborative coordination.
There is no single fit for every operator. Before joining or relying on a channel, assess:
Rank #4
- Fit: Does the group serve your sector, region, operational role, or type of organization?
- Participation and trust: Who can take part, how are members verified, and how are conflicts or misuse addressed?
- Speed and actionability: Does information arrive in time to matter, with enough context to guide a decision?
- Information handling: What confidentiality, privacy, minimization, retention, and onward-sharing controls apply?
- Coordination: Are responsibilities, points of contact, and escalation paths understandable before a crisis?
These are practical comparison questions, not a formal standard. Review the organization’s participation terms and handling procedures rather than assuming that membership alone guarantees trust, confidentiality, or useful intelligence.

Transparency can also mean knowing what software components are present in a system. A joint government publication, A Shared Vision of Software Bill of Materials (SBOM) for Cybersecurity, describes how component information can help producers, purchasers, and operators integrate supply-chain details into security processes, including in critical infrastructure. An SBOM can inform assessment and response, but it does not by itself prevent attacks or guarantee that a component is secure.

How to judge whether a sharing arrangement is useful
Use a channel only when its operating model is clear enough to support action. A practical review should establish who shares what, who receives it, how quickly it moves, what safeguards apply, and what each participant is expected and authorized to do. Stronger role clarity can make cooperation more usable; it should complement, not replace, careful control of sensitive information.
