The most valuable features for us are automatic mTLS with a strong identity model, which is critical for a fintech environment where encrypted east-west traffic is non-negotiable. Authorization policies are essential because the ability to explicitly define and enforce which services can call each other has been extremely powerful from a compliance and zero-trust standpoint. Operational simplicity is another valuable feature, as Linkerd’s lightweight design and straightforward control plane reduce cognitive and operational load compared to other meshes. Lastly, having enterprise support and stability through a supported enterprise build with security patches and predictable releases gives us confidence in production.
