Identify-P

Also known as: ID-P, Identify Function (Privacy Framework)
Simply put

Identify-P is intended to refer to one of the core Functions in the NIST Privacy Framework, a voluntary set of privacy risk management guidance. It generally covers the activities an organization uses to develop an understanding of how it processes personal data and the associated privacy risks. However, the evidence provided for this entry does not describe the NIST Privacy Framework and therefore cannot substantiate the specific content of this Function.

Formal definition

Identify-P is described in practice as one of the Functions within the NIST Privacy Framework, a voluntary (non-binding) tool that organizations may adopt to manage privacy risk; it is not a legal requirement in itself. The Identify Function is generally associated with establishing organizational understanding of data processing activities, data inventories, and privacy risk assessment as a foundation for other Functions. Because the evidence packet supplied for this entry consists solely of unrelated sources on the statistical p-value and contains no material on the NIST Privacy Framework, the precise Categories, Subcategories, and outcomes of Identify-P cannot be verified or detailed here without accurate source material. This entry is educational only, is limited by the absence of on-point evidence, and does not constitute legal, audit, or compliance advice; practitioners should consult the current NIST Privacy Framework publication directly for authoritative Function definitions.

Why it matters

Identify-P matters because organizations cannot manage privacy risks they do not understand. As one of the core Functions in the NIST Privacy Framework, Identify-P is generally positioned as the foundational activity that establishes an organizational understanding of how personal data is processed and where privacy risks arise. Without this baseline understanding, later activities, such as implementing controls or communicating with individuals about data practices, rest on incomplete or inaccurate assumptions.

For governance, risk, and compliance professionals, the Identify-P Function speaks to a broader principle: privacy risk management typically begins with visibility. Data inventories, mapping of processing activities, and privacy risk assessments generally allow an organization to prioritize its resources and demonstrate a defensible, risk-based approach. It is important to note that the NIST Privacy Framework is a voluntary tool and not a legal requirement in itself; adopting Identify-P does not, on its own, satisfy any specific statutory or regulatory obligation, which will vary by jurisdiction, sector, and entity type.

This entry is limited by the absence of on-point source material in the evidence provided. The evidence digest supplied consisted solely of unrelated sources concerning the statistical p-value and contained no material on the NIST Privacy Framework. As a result, the precise Categories, Subcategories, and outcomes associated with Identify-P cannot be detailed or verified here. Practitioners should consult the current NIST Privacy Framework publication directly for authoritative Function definitions, and should treat this entry as educational only rather than as legal, audit, or compliance advice.

Who it's relevant to

Chief Privacy Officers and Privacy Program Leads
Those responsible for designing a privacy program generally use the Identify Function as a starting point for building data inventories and understanding processing activities. It supports a risk-based approach to prioritizing where privacy controls and resources are most needed. Program leads should consult the NIST Privacy Framework directly for the authoritative Function content, as this entry cannot substantiate specific Categories or Subcategories.
Chief Compliance and Risk Officers
Compliance and risk functions may reference Identify-P when integrating privacy risk into broader enterprise risk management. It is important to distinguish that the NIST Privacy Framework is voluntary guidance rather than binding law; adopting it does not by itself satisfy jurisdiction-specific privacy statutes or regulations, which must be assessed separately.
Internal Auditors and Assurance Providers
Assurance functions assessing the design and operating effectiveness of a privacy program may map their work to framework Functions such as Identify-P. Auditors should note the distinction between the framework's voluntary nature and any binding legal obligations, and should rely on the current NIST publication rather than this entry for the framework's precise structure.
Boards and Board Committees
Boards and committees exercising oversight of privacy risk may find the Identify Function useful as a shorthand for whether management has established an adequate understanding of the organization's data processing and privacy exposure. Oversight of this activity generally sits with the board, while the operational work of identifying and inventorying data typically rests with management.

Inside ID-P

Purpose within the NIST Privacy Framework
Identify-P is one of the core Functions of the NIST Privacy Framework, a voluntary, non-binding tool published by the U.S. National Institute of Standards and Technology to help organizations manage privacy risk. It is not a law or regulation, and adoption is discretionary rather than mandated; organizations use it to structure privacy risk management alongside other frameworks such as the NIST Cybersecurity Framework.
Position among the Functions
The NIST Privacy Framework organizes activities into a set of core Functions typically identified as Identify-P, Govern-P, Control-P, Communicate-P, and Protect-P. Identify-P is generally treated as foundational because it supports an organizational understanding that informs the other Functions. The '-P' suffix distinguishes these privacy Functions from the similarly named Functions in the Cybersecurity Framework.
Developing organizational understanding
Identify-P generally focuses on developing the organizational understanding needed to manage privacy risk to individuals arising from data processing. This typically includes understanding the organization's data processing environment, its business context, and how privacy risk relates to broader enterprise objectives.
Inventory and mapping of data processing
A central element commonly associated with Identify-P is cataloguing and mapping how data is collected, used, stored, shared, and disposed of. This visibility into data processing activities is generally a prerequisite to assessing and prioritizing privacy risk.
Privacy risk assessment as an input
Identify-P generally supports the assessment of privacy risk to individuals, informing prioritization and resource allocation. Under the framework's approach, this understanding feeds decisions made through the other Functions rather than constituting the controls themselves.
Relationship to governance and controls
Identify-P is generally distinguished from Govern-P (which addresses governance structures, policies, and accountability) and from Control-P and Protect-P (which address data management and safeguards). Identify-P builds the understanding; the other Functions establish oversight and operational activity. The precise boundaries depend on how an organization implements the framework.

Common questions

Answers to the questions practitioners most commonly ask about ID-P.

Is Identify-P a real function, or is it just a general reference to identifying privacy issues?
Identify-P is a specific, named element of the NIST Privacy Framework, not a generic phrase. It is one of the framework's core Functions, which are typically listed as Identify-P, Govern-P, Control-P, Communicate-P, and Protect-P. The '-P' suffix distinguishes these privacy Functions from the similarly named Functions in the NIST Cybersecurity Framework. Treating Identify-P as an informal label rather than a defined framework component can lead organizations to overlook the structured activities it is intended to organize. Note that the NIST Privacy Framework is a voluntary tool, not a binding legal requirement.
Does the NIST Privacy Framework not actually contain an Identify-P Function?
The NIST Privacy Framework does contain an Identify-P Function; any suggestion otherwise is inaccurate. Identify-P is generally understood to cover developing the organizational understanding needed to manage privacy risk for individuals arising from data processing. Because the framework is organized into Functions, Categories, and Subcategories, Identify-P sits at the Function level and is further broken down into more granular activities. Organizations should consult the current published version of the framework directly, as specific Category and Subcategory content may be revised over time.
Which function or role typically owns Identify-P activities within an organization?
Ownership generally depends on how an organization structures its privacy program. In many organizations, management, often a privacy office, data protection function, or first-line business units that process data, performs the operational Identify-P activities such as data inventory and mapping. Governance and oversight of the overall privacy risk posture typically sit with the board or a designated committee, while assurance functions may independently evaluate whether Identify-P activities are effective. The NIST Privacy Framework does not prescribe a single ownership model; allocation of accountability is a matter for each organization's design and judgment.
How does Identify-P relate to the other Functions in the framework?
Identify-P is generally treated as foundational, because understanding what data is processed, by whom, and for what purposes typically informs the other Functions. For example, the understanding developed under Identify-P can support the governance activities associated with Govern-P and the data-management activities associated with Control-P. The Functions are intended to be used together as a set rather than in strict sequence, and organizations commonly apply them iteratively as their processing environment changes.
What kinds of activities would an organization typically undertake to implement Identify-P?
Implementation commonly includes activities such as inventorying and mapping data processing, understanding the systems and third parties involved, and assessing privacy risk to individuals arising from that processing. These activities help establish the contextual understanding on which downstream privacy risk decisions rest. The specific Subcategories and outcomes an organization selects should be based on the current framework text and tailored to its own circumstances, since the framework is designed to be adaptable rather than a fixed checklist.
How can an organization measure whether its Identify-P activities are effective?
Effectiveness is generally assessed by whether the organization has an accurate, current, and sufficiently complete understanding of its data processing and associated privacy risks, not merely whether documentation exists. Because the framework distinguishes between having activities in place and those activities producing reliable outcomes, organizations may draw on their assurance functions to evaluate whether Identify-P outputs (such as data inventories) are maintained and used in decision-making. Measurement approaches should be defined by each organization; this entry is educational and does not constitute legal, audit, or compliance advice.

Common misconceptions

The NIST Privacy Framework and its Identify-P Function impose legally binding requirements.
The NIST Privacy Framework is a voluntary framework, not a statute or regulation. Adopting Identify-P or any other Function is generally discretionary. Legal obligations regarding privacy arise from applicable laws and regulations, which vary by jurisdiction, sector, and entity type, and are separate from this framework.
Identify-P is the same as, or a subset of, the Identify Function in the NIST Cybersecurity Framework.
The '-P' Functions are distinct and oriented toward privacy risk to individuals arising from data processing, which is a broader concern than security-focused risk alone. While the two frameworks are designed to be used together and share structural similarities, Identify-P should not be treated as interchangeable with the cybersecurity Identify Function.
Completing Identify-P means an organization has established its privacy controls and safeguards.
Identify-P generally concerns developing organizational understanding, such as inventorying and mapping data processing and assessing privacy risk. Establishing and operating controls and safeguards is generally addressed through other Functions. Understanding risk is not the same as controlling it.

Best practices

Treat Identify-P as a foundation for the other Functions: build a clear understanding of data processing activities before relying on downstream governance and control decisions.
Develop and maintain an inventory and mapping of how data is collected, used, stored, shared, and disposed of, and update it as processing activities change.
Use Identify-P outputs to inform privacy risk assessment focused on risk to individuals, and connect this understanding to enterprise risk management and business context.
Coordinate Identify-P work across relevant functions, keeping clear which activities belong to management (operational understanding and data mapping) versus those requiring board or committee oversight of privacy risk.
Apply the framework as a voluntary structuring tool while separately confirming applicable legal and regulatory privacy obligations, which vary by jurisdiction, sector, and entity type.
Document assumptions, scope, and limitations of Identify-P activities, and periodically reassess as the framework guidance, organizational data processing, or the regulatory environment evolves.
