vTiger CRM Field Masking Case Study | Data Privacy & Security

Client Overview

The customer is a mid-sized organization using vTiger CRM to manage customer data, sales transactions, and operational workflows. The CRM is accessed by multiple departments such as sales, support, finance, and management, each with different levels of data access requirements.

The organization stores sensitive information including contact details, financial identifiers, and confidential business data, making data security a top priority.

Improve Data Privacy and Access Control

As CRM usage expanded across departments, GLAC faced increasing risks related to sensitive data exposure. Multiple teams accessed customer and financial information, making it difficult to enforce strict data privacy controls.

The lack of field-level restrictions created security gaps, compliance risks, and challenges in limiting access without disrupting daily CRM operations.

Sensitive Data Visibility

Critical fields such as phone numbers and financial data were visible to unauthorized users.

Risk of Internal Data Misuse

Increased chances of accidental or intentional misuse of confidential information.

Compliance Pressure

Growing need to comply with regulations like GDPR and PCI-DSS.

Limited Field-Level Control

No effective mechanism to hide sensitive fields while maintaining usability.

Role-Based Field Masking in vTiger CRM

CRMTiger implemented Field Masking within vTiger CRM to protect sensitive information while ensuring authorized users retained necessary access.

The solution enabled partial or full masking of sensitive fields based on user roles, aligning CRM access with data privacy and security requirements.

Field Masking Enablement

Masked sensitive fields to hide or partially display confidential values.

Role-Based Access Control

Visibility of fields controlled based on user roles and permissions.

Custom Masking Logic

Applied masking rules across standard and custom CRM modules.

Compliance-Oriented Design

Ensured CRM data handling aligned with regulatory requirements.

Advanced Field Masking Capabilities

The implemented solution provided flexible and secure control over sensitive CRM data without impacting usability.

Partial Data Masking

Displayed masked values such as phone numbers in obfuscated formats.

Full Field Encryption

Completely hid highly sensitive financial and identification data.

Role-Based Visibility

Allowed only authorized users to view or edit sensitive fields.

Extensible Masking Rules

Supported custom modules, contextual rules, and security extensions.

Stronger Security and Compliance Outcomes

The Field Masking implementation significantly strengthened GLAC’s CRM data protection strategy while maintaining operational efficiency.

Enhanced Data Protection

Sensitive customer data was securely protected from unauthorized access.

Reduced Internal Exposure Risk

Minimized chances of insider misuse or accidental data leaks.

Improved Compliance Readiness

Better prepared for audits and regulatory requirements.

Seamless CRM Adoption

Security enhancements implemented without disrupting business workflows.

Project Objectives

Data Protection: Prevents unauthorized visibility of sensitive information
User Access Control: Ensures users see only what they need
Regulatory Compliance: Helps meet GDPR, HIPAA, PCI-DSS, and similar requirements
Internal Threat Prevention: Reduces risk from insider misuse or accidental exposure

Implementation Approach

Identification of Sensitive Fields

Personally identifiable information
Financial and payment-related fields
Confidential business and operational data

Custom Field Masking Strategy

Custom fields were configured to display masked values where necessary. For highly sensitive data, encryption was applied so that values remained unreadable without proper authorization.

Role-Based Access Control

Sensitive fields were restricted for standard users
Full or partial visibility was granted only to authorized roles such as administrators or finance users
Field-level visibility aligned with job responsibilities

Extensions and Custom Enhancements

Applying field masking logic to custom modules
Leveraging security extensions to enforce stricter field access
Automating masking behavior based on role and context

Monitoring and Audits

Review user access to sensitive fields
Validate masking rules
Ensure compliance with internal and external security policies

Project Performance Summary

Identification of Sensitive Fields

Sensitive fields such as phone numbers, financial data, and identifiers were visible to users who did not require full access
Risk of accidental or intentional internal data misuse
Growing pressure to comply with data protection regulations like GDPR and PCI-DSS
Difficulty enforcing least-privilege access at the field level
Limited mechanisms to hide sensitive data while still allowing CRM usability

Results Achieved

Stronger protection of sensitive customer data
Reduced risk of internal data exposure
Improved compliance readiness for audits and regulations
Greater confidence among stakeholders regarding CRM security
Limited mechanisms to hide sensitive data while still allowing CRM usability. Seamless CRM usage without disruption to business processes

Best Practices Followed

Enforced least-privilege access principles
Conducted periodic role and permission reviews
Combined field masking with encryption, strong authentication, and audit logs
Trained users on data privacy responsibilities

The Solution: Field Masking in vTiger CRM

To address these challenges, the organization implemented Field Masking within vTiger CRM with support from CRMTiger.

Field Masking allows sensitive information to be partially hidden or fully obscured from unauthorized users. Instead of displaying complete values, fields show masked representations or remain hidden entirely based on user roles and permissions.

Examples of Masking

Phone numbers displayed as 9123-****-****
Financial or identification fields are hidden or encrypted
Confidential fields visible only to authorized roles

This ensured customer privacy while allowing authorized users to perform required tasks.
