Compare VisoTrust with Whistic

Overview of VISO TRUST and Whistic  

Both VISO TRUST and Whistic operate in third-party risk management, but they solve fundamentally different problems.

Whistic helps organizations collect vendor questionnaires more efficiently.

VISO TRUST helps enterprises make fast, defensible vendor risk decisions at scale.

Whistic improves how questionnaires are exchanged.

VISO TRUST replaces the need to rely on questionnaires as the primary risk signal.

This difference becomes critical as vendor ecosystems scale and businesses demand faster onboarding without increasing risk headcount.

The Core Difference

Whistic modernizes questionnaire exchange

Whistic allows vendors to publish completed security questionnaires (often SIG-based) that customers can reuse instead of sending new surveys.

This reduces email coordination and duplicated survey effort.

But risk decisions still rely on:

  • Vendors filling out questionnaires
  • Security teams reviewing static answers
  • Periodic reassessment cycles
  • Manual follow-up and evidence validation

The operating model remains questionnaire-driven.

VISO TRUST modernizes vendor risk operations

VISO TRUST removes questionnaires as the bottleneck.

Instead of repeatedly asking vendors to fill out forms, VISO TRUST delivers:

• AI-enabled assessments in seconds
• Reusable, validated vendor intelligence
• Continuous monitoring across vendors and downstream providers
• Automated lifecycle workflows
• Evidence-backed assurance for audits and leadership

Risk decisions happen continuously — not just when surveys are completed.
