Ironport

IronPort Systems was an email and web security gateway company founded in 2000 in San Bruno, California, known for its anti-spam, anti-virus, anti-phishing, and URL-filtering appliances and its SenderBase email reputation service. Cisco Systems acquired IronPort in 2007 for approximately $830 million; the products were rebranded as Cisco Email Security and Cisco Web Security and the standalone IronPort brand and pricelist were fully retired by late 2012. IronPort no longer operates an independent public website, developer portal, or API surface — its domain now resolves into Cisco — so this profile is retained as a historical Menlo Ventures portfolio company rather than an active API provider awaiting enrichment.

Ironport is profiled on the APIs.io network. Tagged areas include Company, Email Security, Web Security, Anti-Spam, and Email Gateway.

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