Third-Party Breaches
The Hidden Risk
Your security is only as strong as your weakest vendor. One compromised supplier can cascade across thousands of organizations, including yours.

Your vendors are your vulnerability
Cloud Providers
Shared infrastructure
When AWS, Azure, or Google Cloud has an incident, thousands of businesses are affected simultaneously. Your security is only as strong as your provider's.
Example: Microsoft Exchange Online breach exposed US government emails (2023)
Software Vendors
Trusted access
SaaS tools and enterprise software have deep access to your systems. A compromised vendor update can spread malware across all customers.
Example: SolarWinds attack affected 18,000+ organizations including Fortune 500
Service Providers
Data handling
Outsourced IT, payroll, and business services handle sensitive data. Their breach becomes your breach.
Example: Capita breach exposed data from hundreds of UK councils and NHS trusts
APIs & Integrations
Connection points
Every integration is a potential entry point. Attackers increasingly target the connections between systems rather than systems themselves.
Example: CircleCI breach compromised customer secrets and environment variables
One breach, thousands of victims
Supply chain attacks are devastating because they multiply impact exponentially.
