Scored 0–5 against a published rubric. Independent analysis, no vendor sponsorship.

Overview

Aserto offers fine-grained authorization built on the open-source Topaz engine, which combines OPA-style policy with a relationship-based directory.

Capability deep-dive

Open-source Topaz, good developer ergonomics, and a blend of policy and relationship models are the strengths. As a smaller vendor, enterprise governance features and ecosystem are lighter than the largest players.

Pricing

Open-source Topaz free; managed and enterprise tiers usage-based.

Bottom line

A developer-friendly authorization option blending OPA policy with relationship data.
