Third-party Risk Assessment and Management

A network perimeter is only as secure as the weakest vendor who holds the keys to its data. You can spend millions hardening your firewalls, enforcing multi-factor authentication, and patching operating systems, but the moment you outsource a service or deploy a piece of commercial software, you extend your attack surface into environments you do not govern. This is the crux of third-party risk management, the systematic process that evaluates the security risks introduced by external vendors, suppliers, and business partners. In modern IT infrastructure, we no longer defend an isolated castle; we defend an interconnected web of supply chains, cloud platforms, and managed services.
