The Attacker Resistance Score

Security scores have sought the easiest metrics to measure instead of the ones that truly matter. Until now.

Synack’s Attacker Resistance Score (ARS) provides a realistic assessment and benchmark of assets’ security risk, from a hacker’s perspective.

A Score Based in Reality, Not Guesswork

The Attacker Resistance Score (ARS) measures an asset's hardness against attack based on penetration test performance data. A data-driven score, rather than a generic hypothesis or noisy scanner results.

About the Score

The Synack Hacker-Powered Security platform provides an Attacker Resistance Score for every asset and organization that Synack tests.

ARS is calculated based on the data generated by the Synack Red Team (SRT) and proprietary technology during a crowdsourced pen test.

Attacker Resistance Score
  1. Attacker Cost

    The level of effort exerted by the Synack Red Team to find vulnerabilities
  2. Severity of Findings

    The impact and quantity of vulnerabilities discovered in an assessment
  3. SRT Skill

    Complexity of the vulns based on SRT skill required for vuln discovery
  4. Remediation Efficiency

    How efficiently identified issues are resolved

Attacker Resistance Score

Modern Attack Surfaces change constantly. Continuous change requires continuous testing handling:

  1. 1. Release Software
  2. 2. Test & Find Vulnerabilities
  3. 3. Remediate & Verify
  4. 4. Release Hardened Software
  5. 5. Repeat
