Mutual TLS now available for Workers

In the digital world, security is crucial for businesses of all sizes. Cloudflare's Mutual Transport Layer Security (mTLS) helps secure a wide range of network services and applications such as APIs, web applications, microservices, databases, and IoT devices. mTLS enhances standard TLS by validating both the client and server during the connection establishment process. It uses cryptographically signed certificates for authentication, which are harder to spoof than passwords or tokens. mTLS is useful when a managed list of clients need access to a server. Some common use cases include communications between APIs or microservices, database connections from authorized hosts, and machine-to-machine IoT connections. mTLS support on Cloudflare Workers allows communication with resources that enforce an mTLS connection, making it easier to implement security measures for businesses in the digital age.
