Buoyant Adds Zero Trust Network Policies To Linkerd 2.11


Buoyant has announced new security features in Linkerd and in Buoyant Cloud, its SaaS platform for running Linkerd in mission-critical environments. These features include the launch zero-trust network policies in the new Linkerd 2.11 release as well as the addition of new network policy management capabilities in Buoyant Cloud.

Paired with the release of Linkerd 2.11 is the launch of new features in Buoyant Cloud that allow Linkerd users to manage their policies and to monitor the effect they have on the traffic in their clusters. With Buoyant Cloud, users can now easily verify the policies that are in effect for each allowed or attempted type of traffic on their cluster, and detect anomalies such as unexpected plaintext traffic or policy violations. Combined with Buoyant Cloud’s existing feature set, these features reinforce Buoyant Cloud’s role as an essential tool for security-conscious Linkerd operators.

In addition to the network policy enforcement features, Linkerd 2.11 also introduces several improvements and performance enhancements, which include retries for gRPC calls, a fix for container startup ordering issues, and further reductions in Linkerd’s data plane and control plane resource usageā€”building on its demonstrated ability to be many times smaller and faster than other service meshes such as Istio.

The 2.11 release continues a momentous year for Linkerd, which recently became the only service mesh to achieve graduated status from the Cloud Native Computing Foundation, the highest level of project maturity tracked by the foundation.
