Our S5 proxies use standard ports 1080, 4145, and 5050. You can also use custom ports for dedicated proxy plans based on your requirements. This port flexibility is critical for seamless brand protection workflows, including global counterfeit detection, unauthorized seller monitoring, and trademark infringement tracking across 195+ countries. Standard ports ensure universal compatibility with automation tools and monitoring software, while custom ports add an extra layer of anonymity for sensitive legal evidence collection. Whether running 24/7 automated scans for MAP price violations or accessing region-locked marketplaces, our S5 proxy ports maintain undetectable, stable connections—avoiding IP blocks and ensuring accurate data collection for effective brand protection enforcement.
