PII (Personally Identifiable Information) is information that can identify a person, such as their name, email address, phone number, Aadhaar number, or payment information.

What is sensitive data?

Sensitive data is information that needs extra protection because unauthorized access or exposure could cause harm. This can include PII, financial information, credentials, health information, and confidential business data.

What is data tokenization?

Data tokenization replaces sensitive data with a secure token. The original value is stored separately, while applications can work with the token instead.

What is detokenization?

Detokenization is the process of converting a token back to its original value when an authorized application needs the sensitive data.

What is a data privacy vault?

A data privacy vault securely stores sensitive information separately from the systems that process it. Applications can use tokens instead of exposing the original data.

What is the difference between tokenization and encryption?

Encryption transforms data so it can be restored with a key. Tokenization replaces the original data with a token and stores the original value separately.

How does tokenization protect PII?

Tokenization replaces PII with tokens before it is shared with other systems, helping reduce exposure of the original sensitive data.

What is Securelytix Vaultkey?

Securelytix Vaultkey is a data tokenization and privacy vault platform that helps protect sensitive data across AI and non-AI applications.

How does Vaultkey protect data used by AI agents?

Vaultkey can tokenize sensitive data before it is passed to AI agents, APIs, tools, or other services, while keeping the original value securely vaulted.

How does Vaultkey protect data in AI applications?

Securelytix Vaultkey tokenizes sensitive data before it reaches AI models, helping keep raw PII out of AI prompts and downstream systems.

The story

Modern software createda data sprawl problem.

PII moves across applications, APIs, AI models, agents, logs, and third-party services. Every new connection creates another place where sensitive data can be exposed. The question is no longer where data is stored. It's where it travels.
