Overview

IP whitelisting allows you to control which IP addresses can access your deployed Core instances on Blnk Cloud. This provides an additional layer of security by restricting access to only trusted sources. When IP whitelisting is enabled, only the IP addresses you specify will be able to make requests to your Core instance. By default, Blnk Cloud allows connections from any IP address until you configure the whitelist.
  • Access control: Prevent unauthorized access from unknown sources.
  • Compliance: Meet security requirements for sensitive financial applications.
  • Network isolation: Ensure only your applications and services can connect to your Core.
