Secure mesh has strengthened zero‑trust traffic and improves compliance visibility
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.

Enhanced microservice security and advanced traffic management and good authentification

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Buoyant Enterprise for Linkerd significantly improved our security posture by enforcing mTLS across all services with minimal operational complexity."
"Security and compliance have been enhanced with Zero Trust featuring mTLS, workload identity, and end-to-end encryption without code changes."
"Buoyant Enterprise for Linkerd has made it simple for us to deploy and operate Linkerd across our clusters."
"Buoyant Enterprise provides superb support, and the cost savings from HAZL make the license almost cost neutral."
"Istio's best feature is that it's easy to use."
"Istio has positively impacted my organization by helping our architecture design and development, and we use this as a mesh, applying it for every single application and using those components, which is helping our company and our clients to do many different aspects for all the use of Istio."
"We moved them to the Istio framework and in this particular project we started from scratch, and we are happy with the amount of effort it has saved."
"Istio can save you time in terms of network troubleshooting."
"The initial setup is pretty straightforward."
"We use Istio for Service Discovery and routing traffic."
"Istio makes all that much easier - traffic splits, percentage traffic splits, doing some sort of chaos testing to see how it works."
"The security feature with mutual TLS authentication, which is identity-based, and the traffic management using cloud load balancers are very valuable."
 

Cons

"I hope HAZL load bands can be tuned more easily or even automatically."
"Reducing the latency between the control plane and the data plane would be beneficial."
"If someone doesn't understand Kubernetes, they'll have issues working with Istio."
"I've seen applications where they had such strict time constraints, they couldn't use Istio because it was too much overhead."
"Istio's documentation is basic and would benefit from more examples."
"Istio needs to be more mature and user-friendly."
"Istio has issues with performance."
"It would be good if the solution had more community forums."
"Based on my experience, the solution could be improved. They could simplify the learning process so that users can understand how its features work together, especially with components like Kibana. Learning about the different components is necessary. For instance, you need to understand the traffic flow, potential bottlenecks, and the architecture within Istio."
