How Does Vulnerability Chaining Work?

Vulnerability Chaining identifies realistic multi-step attack paths across your estate, combinations of individually-scored vulnerabilities that, when chained together by an attacker, create materially higher risk than their individual severity scores suggest.

What is it?

Individual vulnerability scores (CVSS, severity ratings) assess each finding in isolation. In practice, attackers rarely rely on a single vulnerability, they pivot from one weakness to the next to achieve a larger objective such as full system compromise, data exfiltration, or lateral movement. Vulnerability Chaining identifies these realistic combinations within your own validated findings.

How it works?

  • Chain Identification

    • AI Insights analyzes validated findings on a given asset to identify sequences of vulnerabilities that plausibly combine into a single attack path, for example, default credentials providing initial access, followed by a remote code execution flaw, followed by weak internal authentication enabling lateral movement.

  • Step-by-Step Table

    • Each identified chain is presented as an ordered table of steps, with the specific vulnerability and a short description at each step.

  • Chain Narrative

    • A plain-language narrative explains how an attacker would realistically move through the chain, what each step enables, and what the ultimate impact would be (e.g. full database compromise, payment bypass, administrative takeover).

  • Sequence Graph

    • A visual sequence graph accompanies each chain, showing the attack path step by step.

  • Cross-Chain Summary

    • Where multiple chains are identified across different assets, a summary table lists each chain's entry point, terminal impact, and key amplifying vulnerabilities, making it easy to compare compound risk across the estate.

Features & Benefits

  • Compound Risk Visibility: Surfaces risk that individual CVSS/severity scores alone would understate.

  • Realistic Attacker Perspective: Chains are built from combinations that plausibly occur together, not theoretical worst-case scenarios.

  • Prioritization Aid: Assets involved in the highest-impact chains can be prioritized for remediation regardless of any single vulnerability's individual score.

  • Clear Communication: The narrative and sequence graph make compound risk easy to explain to both technical and non-technical audiences.

Common Use-Cases

  • Remediation Prioritization: Focus effort on breaking the earliest step in a high-impact chain, rather than treating every finding as equally urgent.

  • Executive & Board Reporting: Communicate compound risk in a way that a raw vulnerability list cannot.

  • Red Team / Attack Path Validation: Cross-check identified chains against known attack paths or recent penetration test findings.

  • Architecture Review: Use recurring chain patterns (e.g. weak credentials enabling RCE) to identify systemic control gaps rather than one-off fixes.
