Vendor security as a shared ecosystem responsibility: A framework for connected communications environments

As enterprise workflows have evolved from isolated applications to interconnected ecosystems involving multiple vendors and platforms, traditional one-at-a-time vendor security evaluations have become insufficient. Modern business operations increasingly rely on real-time interactions across communications platforms, identity providers, CRMs, AI systems, and cloud infrastructure, necessitating a broader focus on how data, permissions, and operational risks are managed across these interconnected environments. This shift demands an understanding of how risks propagate through relationships between systems, permissions, and automated workflows, highlighting five key risk vectors: permission inheritance, automation propagation, credential and token exposure, subprocessor chain opacity, and disruption propagation. Communications platforms, being central hubs that integrate various business processes and AI-enabled functions, require dedicated governance attention due to their high trust and potential for misuse. Effective governance in this context involves adopting a shared responsibility framework across platform vendors, developers, and organizations, focusing on transparency, accountability, and the management of AI-enabled features and subprocessors. As regulatory frameworks like the EU AI Act and GDPR increasingly emphasize ecosystem governance, organizations must adapt their practices to ensure resilient and governable communications workflows.
