Prosimo

Prosimo is a multi-cloud networking platform that gives enterprises a full-stack cloud transit, security, performance, observability, and cost-management layer across AWS, Azure, Google Cloud, and Oracle Cloud. Its Application eXperience Infrastructure (AXI) abstracts cloud-provider networking constructs and ties network transit, micro-segmentation, zero-trust policy, WAF, and observability into an autonomous, ML-driven control plane. Prosimo exposes that control plane programmatically through a first-party Terraform provider (prosimo-io/prosimo) for full lifecycle management of cloud gateways, network and application onboarding, policies, namespaces, and security profiles; a companion Pulumi bridge repository and reusable Terraform modules are published on GitHub. Prosimo was venture-backed by General Catalyst, WRVI Capital, and BlackRock; industry sources report it was subsequently acquired by Palo Alto Networks.

Prosimo is profiled on the APIs.io network. Tagged areas include Company, Cloud Networking, Multi-Cloud, Networking, and Zero Trust.

Prosimo’s developer surface includes support, documentation, and 8 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/prosimo: open an issue to ask a question, or submit a pull request to add artifacts.
