What are the alternatives to security ratings for vendor risk?

A security rating scores a vendor from the outside, and the alternative is to verify the vendor’s controls with evidence, combining questionnaire answers, the evidence behind them and external signals in one score, as the DigitalXForce third-party risk module does. A rating stays useful as an early warning, but it cannot be the whole answer.

What a security rating measures

A security rating is an outside-in score of a supplier’s internet-facing posture. It is built from what can be observed from the internet, such as exposed services, open ports and leaked credentials, and it needs no cooperation from the supplier. That makes it quick to run across a large supplier base. A score that needs no cooperation from the supplier also gets none, so it cannot see the controls inside the supplier: who can reach your data, whether backups are tested, or how the supplier manages its own suppliers.

Four alternatives, and what each one adds

A questionnaire records what the supplier says about its controls. It reaches inside the supplier, but on its own it is a statement rather than proof.
An evidence review reads the supplier’s SOC 2 and ISO/IEC 27001 reports. DigitalXForce reviews these reports with automation and AI, and the independent auditor who issued each report remains its source.
Connector evidence reads configuration and compliance signals from the supplier’s own systems, and never business records or customer data. For critical suppliers it needs the customer’s right-to-audit clause and the supplier’s consent.
Continuous external monitoring keeps the outside view running. External Risk View watches exposed services and open ports, misconfigurations, vulnerability exposure, dark web and breach intelligence, lookalike domains and cyber ratings, and it maps fourth-party and nth-party dependencies without an agent, a questionnaire or the supplier’s cooperation.

Why the strongest programs combine them

In the DigitalXForce third-party risk module, every vendor gets its own score built from its questionnaire answers, its evidence and external signals, so a rating sits beside the rest of the supplier record instead of replacing it. How deep each supplier is checked depends on its tier:

Tier 1 Critical suppliers get External Risk View, AI review of their SOC 2 and ISO reports and connector evidence from their own systems, monitored continuously.
Tier 2 High suppliers get External Risk View, AI review of their reports, connector-assisted evidence and AI-guided questionnaires, refreshed weekly with triggered alerts in between.
Tier 3 Commodity suppliers get External Risk View and an AI-assisted self-assessment, refreshed monthly with triggered alerts.

A material change triggers a reassessment instead of waiting for the annual cycle.

How to start

List the suppliers that hold your data or run a service you cannot work without, and place each one in a tier.
For each Tier 1 supplier, check that the contract carries a right-to-audit clause, because connector evidence depends on it.
Keep your rating service as the early warning across the whole supplier base, and let the evidence decide the suppliers that matter most.

Frequently asked questions

Should we drop our security rating service?

No. A rating is a useful early warning across a large supplier base. The change is to stop treating it as the whole answer, because it is one input to third-party risk management (TPRM), which is the discipline of identifying, assessing, monitoring and controlling the risks an organization takes on through its suppliers, vendors and other outside parties.

Does an evidence-based review need the supplier’s help?

Only for part of it. External Risk View needs no agent, no questionnaire and no cooperation from the supplier. Connector evidence from a critical supplier’s own systems needs the customer’s right-to-audit clause and the supplier’s consent.

How is this different from a vendor questionnaire?

A questionnaire collects the supplier’s answers, and an evidence-based review checks them against what the supplier’s reports and systems show. Questionnaire vs evidence-based TPRM walks through the difference step by step.
