Talon

Talon (Talon Cyber Security) was an enterprise browser security company that built a secure, isolated Chromium-based browser for protecting SaaS and web application access on managed and unmanaged devices, with controls for data loss prevention, zero-trust access, and endpoint posture. Surfaced as a portfolio lead of Lightspeed Venture Partners, the company was acquired by Palo Alto Networks in December 2023 and its product was folded into the Palo Alto Networks Prisma Access Browser (Prisma SASE). Talon no longer operates as an independent company: its former domain (talon-sec.com) redirects to the Palo Alto Networks Prisma Browser product page, and no independent public developer portal, API documentation, or public API surface was found during enrichment. This profile is retained as a company record for network history.

Talon is profiled on the APIs.io network. Tagged areas include Company, Security, Enterprise Browser, Zero Trust, and SASE.

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.

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/talon: open an issue to ask a question, or submit a pull request to add artifacts.
