Vendor Security Assessment
Automate third-party risk evaluation for supply chain security
Third-party vendors introduce security risks to your organization. EdgeDNS enables rapid, automated security assessments of vendor domains to identify risks before they become breaches.
The Challenge
Organizations rely on dozens to hundreds of third-party vendors, each representing potential security risks. Manual vendor security assessments are time-consuming, inconsistent, and often outdated by the time they are completed. Security questionnaires provide self-reported data that may not reflect actual security posture.
The Solution
Use EdgeDNS to automatically assess vendor security posture by analyzing their public-facing infrastructure. Check SSL/TLS configuration, security headers, email authentication, and overall trust scores to identify high-risk vendors requiring deeper review.
Endpoints Used
Combine these EdgeDNS endpoints to build this solution.
/v1/score/securityTry in PlaygroundSecurity Score: Get overall security grade with detailed breakdown
/v1/score/trustTry in PlaygroundTrust Score: Evaluate domain reputation and risk factors
/v1/security/headersTry in PlaygroundSecurity Headers: Audit CSP, HSTS, and other protective headers
/v1/domain/sslTry in PlaygroundSSL Certificate: Verify certificate validity and configuration
/v1/score/emailTry in PlaygroundEmail Score: Check SPF, DKIM, DMARC implementation
Results You Can Achieve
Assess vendors in seconds vs hours
Automated assessment replaces manual questionnaire review
Continuous vendor monitoring
Track security posture changes over time with scheduled checks
Evidence-based risk decisions
Objective security data supplements self-reported questionnaires
Code Example
Assess vendor security posture
async function assessVendorSecurity(vendorDomain) {
const headers = { 'Authorization': 'Bearer YOUR_API_KEY' };
const [security, trust, secHeaders, ssl, email] = await Promise.all([
fetch(`https://api.edgedns.dev/v1/score/security?domain=${vendorDomain}`, { headers }),
fetch(`https://api.edgedns.dev/v1/score/trust?domain=${vendorDomain}`, { headers }),
fetch(`https://api.edgedns.dev/v1/security/headers?url=https://${vendorDomain}`, { headers }),
fetch(`https://api.edgedns.dev/v1/domain/ssl?domain=${vendorDomain}`, { headers }),
fetch(`https://api.edgedns.dev/v1/score/email?domain=${vendorDomain}`, { headers }),
].map(p => p.then(r => r.json())));
// Calculate risk level based on scores
const gradeRank = { 'A': 1, 'B': 2, 'C': 3, 'D': 4, 'F': 5 };
const avgRank = (gradeRank[security.data.grade] + gradeRank[email.data.grade]) / 2;
const riskLevel = avgRank <= 2 ? 'low' : avgRank <= 3 ? 'medium' : 'high';
return {
vendor: vendorDomain,
securityGrade: security.data.grade,
trustScore: trust.data.score,
emailGrade: email.data.grade,
riskLevel,
requiresReview: riskLevel === 'high'
};
