Platform Security and Third-Party Risk Assessment

Platform security is never just about your own code or infrastructure. Every vendor, API, library, and integration expands your attack surface. Third-party risk assessment is the process that exposes those hidden vulnerabilities before they are exploited. Without it, trust in the platform is a gamble.

Strong platform security begins with a complete inventory of external dependencies. Identify who has access, what permissions they hold, and how they interact with core systems. Monitor this data continuously. Threats evolve fast, and stale assessments invite intrusion.

Risk scoring is critical. Evaluate each third party for compliance, historical incidents, breach response times, and security certifications. A well-structured platform security framework ties these factors into a measurable score, helping teams prioritize which risks need immediate action.

Automated scanning should be part of every assessment. Dynamic monitoring catches unauthorized changes, suspicious transfers, and code injections in near real-time. Combined with penetration testing, it reveals weaknesses that static reviews miss.

Data governance rules need enforcement, not just documentation. Control access with least privilege principles. Track data flows between the platform and every third-party connection. Encrypt at every point. Log everything.

Contractual protections can support technical defenses. Define security requirements, notification windows for incidents, and audit rights in vendor agreements. The legal framework should match the technical threat model.

Platform security and third-party risk assessment are inseparable. Any gap in assessing external integrations becomes a shortcut for attackers to bypass your defenses.
