CMMC 2.0 Level 1What is PII protection?
PII protection safeguards personally identifiable information and other sensitive personal data that can identify, contact, locate, distinguish, or be linked to an individual. That includes direct identifiers such as names, Social Security numbers, email addresses, phone numbers, account identifiers, and government-issued IDs, as well as combinations of data that become identifying when linked together. Privacy frameworks use different terms and scopes, including personal data under GDPR and personal information that may relate to a person or household under CCPA. Effective protection reduces where this data appears in cleartext while preserving the workflows that legitimately need to use it.
Protect PII at the value level
Encrypt, tokenize, or mask selected fields and records instead of relying only on disk, database, network, or perimeter controls that still expose data on authorized access paths.
Keep protection with the data
Protect sensitive values before they move through applications, databases, warehouses, APIs, analytics pipelines, and downstream copies, reducing the number of systems that hold cleartext PII.
Return the right runtime outcome
At runtime, Ubiq evaluates the requesting identity, context, and policy before returning the permitted representation, such as cleartext, a partially masked value, a deterministic token, or encrypted data. Access to a system does not automatically mean access to every underlying value.
PII protection is strongest when the value stays protected and each access path receives only the representation it needs.
Protect each PII field with the right method
The appropriate protection method depends on the field, workflow, and required use. These illustrative outcomes show how Ubiq can apply encryption, tokenization, or masking while preserving the application and data workflows that still need to operate.

Where traditional PII controls leave a runtime gap
Most organizations already use IAM, database permissions, encryption at rest, and masking. Those controls matter, but they do not always govern which version of each sensitive value is returned after an identity reaches an approved application, database, API, or analytics path.
Access to the system can still expose every field
IAM, application roles, and database permissions decide who can enter a system. They do not always control which version of each sensitive value is returned after access is granted.
PII spreads beyond the original database
Sensitive values are copied into warehouses, reports, logs, test environments, data pipelines, vendor workflows, and AI systems, where the original access controls may no longer apply consistently.
Encryption at rest does not stop live-data exposure
Disk and database encryption protect storage media, but authorized applications, queries, compromised credentials, and privileged access paths can still receive PII in cleartext.
Static masking cannot adapt the result at request time
A pre-masked copy provides a fixed representation. It may be too restrictive for an approved workflow and too revealing for a lower-trust consumer.
Ubiq closes that runtime gap by protecting the value and evaluating identity, context, and policy when the data is requested.
How Ubiq works
Same sensitive data. Different identities. Different runtime outcomes.
Ubiq evaluates the requesting identity, context, and policy at runtime, then returns the PII representation appropriate to that access path.

Where teams protect PII
PII moves through far more than a system of record. These are the workflows where value-level protection and runtime outcomes reduce unnecessary cleartext exposure.
Customer and employee records
Protect names, addresses, contact details, government identifiers, account IDs, and employment data while approved operational workflows continue to function.
Analytics and data warehouses
Give analysts and BI tools masked or tokenized identifiers so teams can measure behavior and trends without broad access to original PII.
Dev, test, and lower environments
Provision realistic protected data to engineering, QA, and vendor workflows without copying cleartext personal information into less-controlled systems.
Customer support and operations
Let support teams verify a customer with partial values while approved fraud, HR, or compliance workflows receive the full information they require.
AI, RAG, and agent workflows
Keep source PII protected while agents and AI workflows receive masked or tokenized representations appropriate to their identity and task.
Privacy and regulatory programs
Reduce unnecessary cleartext exposure and support data-minimization controls for privacy programs governed by requirements such as GDPR and CCPA. Protected values may still remain regulated personal data depending on the implementation and applicable law.
Protect PII across the systems you already run
Ubiq provides a SaaS control plane while protection operations execute inside your environment through application, API, database, and analytics integrations. Sensitive data does not need to be sent to Ubiq for protection or reveal, and teams can apply the right method without adding a central token vault.
Applications and APIs
Apply PII protection through SDKs and APIs where personal data enters, leaves, or is used by an application workflow.
Databases and warehouses
Protect and reveal sensitive fields through SQL UDFs and database and data warehouse integrations.
Existing IAM and identity context
Use the identities and access policies your organization already manages to govern runtime data outcomes.
Customer-controlled data protection
Keep sensitive data and cryptographic operations within your environment, with customer-managed HSM or KMS options where required.
Customer-managed keys
Use your HSM or KMS where required so key ownership stays with your security team.
No central token vault
Use vaultless tokenization without operating a lookup database that becomes another sensitive store to scale and secure.
Frequently asked questions
What is PII protection?
PII protection is the set of technical and operational controls used to safeguard data that identifies or can be linked to a person. Common controls include field-level encryption, tokenization, masking, access policy, key management, monitoring, and data minimization. Ubiq focuses on protecting the sensitive value itself and governing the representation returned to each identity at runtime.
What data is considered personally identifiable information?
PII can include direct identifiers such as names, Social Security numbers, email addresses, phone numbers, account identifiers, government-issued IDs, and precise location data. It can also include combinations of indirect identifiers that identify a person when linked together. The exact legal definition varies by jurisdiction and regulatory framework.
How does Ubiq protect PII?
Ubiq protects sensitive fields and records using encryption, vaultless tokenization, masking, and format-preserving protection where appropriate. At runtime, Ubiq evaluates the requesting identity, context, and policy before returning the permitted representation, such as cleartext, a partially masked value, a deterministic token, or encrypted data.
Is encryption at rest enough to protect PII?
Encryption at rest protects storage media and database files, but applications, queries, privileged users, and compromised credentials can still receive PII in cleartext through authorized access paths. Value-level protection reduces this exposure by keeping sensitive fields protected and governing when cleartext is returned.
What is the difference between PII masking and tokenization?
Masking obscures part or all of a value, such as showing only the last four digits of an identifier. Tokenization replaces the sensitive value with a protected substitute. Ubiq can use both as runtime outcomes, so one identity may receive a masked value while another workflow receives a deterministic token for approved correlation and joins.
Can Ubiq protect PII across applications, databases, and analytics?
Yes. Ubiq integrates through SDKs and APIs, SQL UDFs, and database and data warehouse integrations. This lets teams apply consistent value-level protection across applications, services, APIs, databases, warehouses, analytics, and AI workflows.
How does PII protection support GDPR and CCPA programs?
Protecting PII at the value level can help organizations reduce unnecessary cleartext exposure, enforce data minimization, and limit which identities can receive original personal data. Encryption, tokenization, and masking reduce exposure and support privacy controls, but protected values may still remain regulated personal data depending on the implementation and applicable law. Ubiq provides technical controls that can support privacy programs, while each organization remains responsible for determining its legal and compliance requirements.
Can AI agents use protected PII?
Yes. AI agents can receive masked or tokenized representations appropriate to their identity and task, while original PII remains protected. Ubiq evaluates identity, context, and policy at runtime so an AI access path does not automatically receive the same cleartext data as an approved human or application workflow.
