DATA SECURITY
Protect the Data
That Keeps Your Business Moving
Keep sensitive information protected wherever it lives, moves, or is accessed. Netrust helps organizations strengthen data security with encryption, tokenization, key management, and data loss prevention—so critical information remains protected without getting in the way of business.

Protecting
Sensitive Data
Data Encryption and Tokenization protect sensitive information by reducing what an attacker can access and use—even when systems or data are exposed.
Two methods, different approaches.
Encryption protects the data itself by making it unreadable without the right key. Tokenization reduces exposure by replacing sensitive values with non-sensitive tokens, keeping the original data outside systems that do not need it.
THE TWO METHODS
What Each Approach Does
Encryption and tokenization protect sensitive data indifferent ways. The right approach depends on where the data is used, what needs to remain accessible, and how much sensitive information your systems should retain.
01 — Data Encryption
Protect the data itself.
Encryption transforms sensitive information intoan unreadable form that can only be restored with the appropriate key. The data remains within the system, but its contents are protected from unauthorized access.
02 — Tokenization
Keep sensitive data out of the systems that use it.
Tokenization r eplaces sensitive values with non-sensitive tokens. Applications can continue to process the token while the original value is kept separately and accessed only when required.
HOW THEY WORK
Protect Data Where Exposure Matters Most
Encryption protects sensitive information wherever it resides or moves. Tokenization reduces exposure by replacing sensitive values before they reach systems that do not need the original data.
ENCRYPTION
Sensitive Data → Encrypted Data → Authorized Access
Protects:
Data at rest • Data in transit • Files • Databases • Communications
TOKENIZATION
Sensitive Data → Token → Application / System
Reduces exposure:
Payment data • Customer identifiers •Personal information • Other high-value fields
In many environments, both approaches work together—protecting the original data while reducing how often sensitive values are exposed across applications and systems.
02
Building Effective
Data Protection
The right implementation depends on what you're protecting, where sensitive data is exposed, and which systems actually need access to the original value.
IMPLEMENTATION GUIDANCE
Applying the Right Controls
Effective data protection depends on more than choosing encryption or tokenization. Each approach has different implementation considerations—from key and token management to access controls, integration,and ongoing monitoring.
01
Secure the Token Vault
Keep original sensitive values in a strongly protected and isolated environment with tightly controlled access.
02
Generate Non-Predictable Tokens
Use tokens that contain no meaningful or inferable information about the original value.
03
Control Access to Token Mapping
Restrict access to the systems and users that need to resolve tokens back to their original values.
04
Integrate Without Expanding Exposure
Design tokenization into applications and workflows without unnecessarily reintroducing sensitive data into downstream systems.
05
Monitor Token Usage and Access
Track token activity, access to sensitive values, and exceptions to maintain control and support audit requirements.
DATA ENCRYPTION
05 STEPS
Strong algorithms, keys kept apart, and every operation logged.
01
Use Strong Encryption
Use modern, appropriately configured cryptographic algorithms based on the sensitivity of the data and the environment in which it is stored or transmitted.
02
Encrypt Data in Transit and at Rest
Protect sensitive information while it moves across networks and while it resides in databases, applications, storage, and cloud environments.
03
Protect and Manage Encryption Keys
Separate key management from encrypted data, restrict access, and establish appropriate key rotation and lifecycle controls.
04
Apply Encryption Where Exposure Matters
Identify where data can be exposed across systems, applications, and communication channels, and apply encryption accordingly.
05
Monitorand Audit Encryption
Maintain visibility into encryption controls, key usage, access, and exceptions to support security, compliance, and ongoing risk management.
TOKENIZATION
05 STEPS
Random tokens, a locked vault, and tight limits on who can map them back.
03
Choosing the
Right Approach
Encryption and tokenization address different exposure points. Understanding where each approach fits helps determine what should be protected, where sensitive data should reside, and when using both provides stronger protection.
HOW THEY WORK TOGETHER
Reduce Exposure Across the Environment
Encryption and tokenization can work together to protect sensitive data at different points in its lifecycle.
01
Keep Sensitive Data Out of Applications
Tokenization replaces sensitive values with non-sensitivetokens, reducing the exposure of original data across applications and downstream systems.
02
Protect the Data That Must Remain
The original data remains protected in a secure environment, with encryption applied to reduce exposure if that environment is compromised.
03
Reduce the Value of a Breach
If an attacker gains access to an application or system, exposed tokens provide no direct access to the original sensitive values.
04
Business Impact
Reduce the Impact of Data Exposure
Strong data protection limits what exposed information can reveal, how it can be used, and the consequences of acompromise.
WHAT IT HELPS REDUCE
01
Financial loss
Limit the use fulness of compromised sensitive information and reduce the potential impact of a data breach.
02
Regulatory Risk
Strengthen protection around regulated and sensitive information and support compliance requirements.
03
Operational Disruption
Reduce the exposure of critical data across applications, systems, and workflows.
04
Lost of trust
Protect the information customers, partners, and employees expect your organization to handle responsibly.
WHY IT MATTERS
Data protection isn't only about preventing unauthorized access. It's about limiting the consequences when exposure occurs.
Encryption and tokenization help organizations reduce the amount of sensitive data exposed across their environments, strengthen control over how it is accessed, and limit the value of compromised information.
