ERP system integration with third-party apps, however, poses serious security risks because businesses cannot afford data breaches or illegal access that could jeopardize financial records, operational integrity, and reputation. Because ERP systems are appealing targets for cybercriminals looking to obtain sensitive company data, ensuring secure data exchange is an urgent concern. ERP integration security is still a problem, despite the numerous security frameworks and measures that have been put forth. Current methods frequently fall short of effectively addressing new threats. To guarantee the safe and smooth integration of cloud-based ERP solutions with external systems, this study presents an extensible security framework. The framework reduces the risk of data interception and unauthorized access by utilizing functional and technical security measures to produce a strong, adaptable security model. To prevent data leaks and unauthorized changes, the implementation is divided into two phases: (1) securing outbound data flow from the ERP portal to third-party systems, and (2) securing inbound data flow from third-party systems into the ERP portal, which protects against malicious intrusions and breaches of data integrity. 2025 61 76 3772 https://creativecommons.org/licenses/by/4.0/ 10.54216/JCIM.160205 https://americaspg.com/journal/2/article/3772 https://americaspg.com/storage/01744487752.pdf
