The short version

  • Only Linkerd has a free tier, so it costs nothing to try first.
  • Each has a real cost: Linkerd deliberately fewer features than Istio, so complex routing and multi-cluster policy can hit its limits; Wiz no public pricing; licensing requires a custom quote based on workloads and sensors.
  • They diverge on capability: Linkerd covers Automatic mutual TLS, Wiz covers Cloud security posture management.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Linkerd

  • Deliberately fewer features than Istio, so complex routing and multi-cluster policy can hit its limits
  • Kubernetes only, with no story for workloads outside a cluster
  • A sidecar per pod is still real memory and latency overhead, however small, and a mesh is another layer to debug during incidents

Wiz

  • No public pricing; licensing requires a custom quote based on workloads and sensors.
  • Modular licensing across Cloud, Code, Defend, and Sensor products can complicate cost planning.
  • Full runtime protection value depends on deploying Wiz Sensor agents, adding operational overhead.
  • Primarily aimed at mid-to-large enterprises despite the smaller Wiz Go bundle.

Answered from the vendors’ own pages

Linkerd: Is Linkerd free?

The open-source project is free. Buoyant, its maintainer, sells enterprise distributions and support separately.

Wiz: How much does Wiz cost?

Wiz does not publish standard pricing. The platform uses modular licensing based on workloads, active developers, log ingestion, or sensors. All pricing requires requesting a custom quote directly from the company.

Linkerd: Linkerd or Istio?

Linkerd trades features for simplicity, with a smaller proxy and far less configuration. Istio is more capable and correspondingly more work to run.

Wiz: Does Wiz offer a free trial?

No free trial information is mentioned on Wiz's pricing page. Pricing is determined by custom quote based on organizational needs.

Source
Linkerd: Do I need a service mesh at all?

Only if you need mutual TLS, uniform retries or per-service traffic metrics across many services. For a handful of services it is usually more machinery than the problem justifies.

Wiz: What products does Wiz offer?

Wiz provides five modular licensing options: Wiz Cloud, Wiz Code, Wiz Defend, Wiz Sensor, and Wiz Go Bundle for SMBs, allowing organizations to scale based on specific security requirements.
