A fully programmable secure web gateway
TL;DR
Cloudflare has introduced a fully programmable secure web gateway that allows users to run custom code inline during security policy evaluations. This innovation addresses the limitations of traditional gateways, enabling greater flexibility and customization for complex environments.
✦ Why It Matters
Evaluate your current security infrastructure and consider migrating to Cloudflare's programmable gateway for enhanced customization.
Key Takeaways
- Explore Cloudflare's new Forward action for traffic manipulation.
- Utilize custom validation functions to enhance security policies.
- Reduce reliance on additional proxy infrastructure for transformations.
- Assess your security needs to leverage Cloudflare's programmability.
Full Summary
For nearly 30 years, secure web gateways have operated on a simple model where traffic matches conditions leading to terminal actions like Allow or Block. However, this model struggles in complex environments, prompting Cloudflare to enhance its Gateway and Data Loss Prevention (DLP) services.
By integrating with its edge computing platform, Cloudflare now allows users to implement custom logic directly in the policy evaluation process through a new action called Forward. This enables users to manipulate traffic and incorporate their own data during security decisions.
For instance, security teams can now inject HTTP headers based on JSON Web Token (JWT) claims without needing additional infrastructure like NGINX proxies. This shift not only reduces maintenance overhead but also enhances the adaptability of security measures to specific organizational needs.
