Our approach

Vendor risk, handled deliberately

Risk-Based Approach

Focus diligence where it matters most — on the vendors with the deepest access to your data and systems.

Assessment Framework

A consistent, defensible framework for evaluating controls, contracts, and shared responsibility.

Ongoing Monitoring

Vendor risk isn't one-and-done — we help you keep watch as relationships and threats evolve.

The program

A repeatable due-diligence process

  1. Prioritize

    Rank vendors by access, criticality, and data sensitivity.

  2. Assess

    Evaluate controls, contracts, and shared-responsibility gaps.

  3. Document

    Capture findings and risk decisions in a defensible record.

  4. Remediate

    Drive fixes and contract changes where exposure is unacceptable.

  5. Monitor

    Re-evaluate on a cadence as vendors and threats change.

What we evaluate

The domains that define vendor risk

Whether the vendor meets the standards your business is held to.

The payoff

Why disciplined vendor oversight pays off

A strong program does more than check a box.

  • Maintain compliance across an extended vendor ecosystem
  • Improve your overall security posture with fractional CISO oversight
FAQ

Vendor due diligence FAQs

What is vendor due diligence?

A structured review of the third parties you rely on — their security practices, data handling, access, and incident expectations — so you understand and control the risk they introduce.

Why does third-party risk matter?

Many breaches originate through vendors and suppliers. If a partner with access to your systems or data is compromised, you can be too.

Which vendors should we review?

Prioritize vendors with access to sensitive systems or data, cloud and IT providers, and any partner whose failure would disrupt your operations.

How does this support compliance?

Structured vendor oversight and documentation support regulatory requirements, cyber insurance questions, and frameworks that require third-party risk management.
