Cyber security has so far been the major challenge faced by enterprises, which continuously invest in third parties and go for outsourcing deals for managing the IT environments. In fact, the extent of outsourcing has only become more complex in the recent years, and therefore demands the establishment of strong frameworks and strategies to assess the security implications of third-party IT outsourcing. This paper analyzes the risk caused by third-party vendors in terms of the external managed service provider-linked vulnerabilities and other liable partnerships. The topics included involve the best ways to assess and mitigate risks within outsourcing contracts, focusing on due diligence, continuous monitoring, and compliance to adequately manage such industry-specifically security protocols. The paper thoroughly reviews the leading frameworks and methodologies intended to provide organizations with actionable methods for ensuring sensitive data and IT infrastructure protection regarding third-party service provision. It presents the absolute need for joint collaboration and clear communication between vendors and clients so that cybersecurity approaches will be uniform and will keep up the resilience of outsourced IT infrastructures despite new threats.
