Aserto

Aserto specializes in cloud-native authorization infrastructure, delivering a focused suite of tools that let development teams externalize, monitor, and continuously refine who can do what inside modern applications. The publisher’s portfolio is anchored by Topaz, an open-source engine that implements both relationship-based (ReBAC) and attribute-based (ABAC) access control so microservices, SaaS dashboards, and CLI utilities can call a single authorization endpoint instead of hard-coding policy logic. Complementing the engine, the Aserto CLI provides an ergonomic command surface for bootstrapping tenants, pushing policy images, and live-testing decisions, while the lightweight utility Check2Decision migrates legacy directory assertions into Topaz’s native check_decision format, accelerating brown-field adoption. For bulk data movement, ds-load streams user, group, and resource records from identity providers or CSV exports into Topaz’s directory layer, keeping permissions data in sync without manual scripting. Together the four components form an end-to-end authorization pipeline suitable for multi-tenant SaaS platforms, internal developer portals, and API gateways that need fine-grained, auditable access rules without embedding complex logic in application code. The publisher’s software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the latest releases and supporting batch installation of multiple applications.
