SecurityScorecard Platform API

SecurityScorecard Platform REST API for continuous security ratings, attack surface management, and third-party risk. Enables AI agents to retrieve company security scorecards and grade history for portfolio monitoring, handle continuous third-party vendor risk assessment automation, access attack surface intelligence for exposed asset discovery, retrieve 10+ risk factor data including DNS health, patching cadence, network security, application security, and hacker chatter, manage vendor portfolio scorecards and peer benchmarking data, handle supply chain risk discovery and nth-party risk mapping, access MAX (Material Attack Surface eXposure) score for quantified cyber risk, retrieve actionable findings and remediation guidance data, manage alert configuration for grade change notifications, and integrate scorecard data with GRC, procurement, and cyber insurance platforms.

Best When

An enterprise using SecurityScorecard wants AI agents to automate vendor security monitoring, attack surface discovery, supply chain risk mapping, cyber insurance data integration, and GRC/procurement integration.

Avoid When

OPERATIONAL RISK: Automated vendor decisions based solely on scorecards can trigger false negatives for well-secured companies with limited external footprint. Grade changes should trigger investigation workflows, not automatic contract actions. Nth-party risk automation requires scoping — supply chains are deep and automation needs bounded scope.

Use Cases

  • Monitoring vendor portfolio security grades from TPRM automation agents
  • Automating procurement risk assessment from vendor onboarding agents
  • Retrieving attack surface findings from security operations agents
  • Integrating security scores with cyber insurance from risk quantification agents

Not For

  • Internal penetration testing without external-facing security monitoring
  • Endpoint security management without external risk posture monitoring
  • Consumer security without enterprise vendor portfolio management

Known Gotchas

  • OPERATIONAL RISK: Use scorecard changes to trigger investigation workflows, not automated vendor decisions — grades reflect external signals, not complete security posture
  • Portfolio subscription limits — API access scoped to companies in portfolio subscription; queries beyond portfolio require additional licensing
  • Python SDK available — securityscorecard Python SDK simplifies auth and pagination; use over raw REST for production automation
  • Rate limit 10K calls/day — default; bulk portfolio monitoring must be spread across calls; use webhooks for change-driven workflows
  • Free company lookup — SecurityScorecard allows free lookup of own company scorecard; useful for testing before enterprise subscription
  • EASM vs scorecard — Attack surface management findings and scorecard data are separate data sets; query both for complete picture
