Your company isn’t an island—vendors, cloud providers, payroll services, and other partners keep things running. But every external connection is also a potential attack path. If your partners are vulnerable, so are you.

The Threat Is Growing

According to Security Scorecard’s 2025 report:

  • 35.5%of breaches stemmed fro hird-party compromise
  • 41.4%of ransomware attacks involved vendor access
  • Clop ransomware group led the charge via supply chain weak spots

What’s at Risk?

  • Compromised vendor credentials = unauthorized access
  • Malware spreads via poorly secured partners
  • Compliance violations from mishandled data
  • Brand damage if your customers’ data leaks from a supplier

6 Moves to Reduce Your Exposure

  • Assess vendors before onboarding
  • Define cybersecurity terms in SLAs
  • Use least privilege for third-party access
  • Monitor external connections in real-time
  • Audit vendors and check certifications
  • Include third-party scenarios in your IR plan
