Zvelo

Zvelo, Inc. is a Greenwood Village, Colorado-based provider of URL categorization, web content classification, and malicious/phishing site detection data. The company traces back to eSoft, Inc., founded in 1984 by Philip L. Becker; eSoft’s SiteFilter web-filtering technology was spun out as a standalone company under the Zvelo name in 2010, and Zvelo now trades publicly on the OTC market under the ticker ZVLO.

Zvelo’s business model is OEM data supply rather than a direct end-user product: its zveloDB URL database and zveloCAT categorization engine provide contextual classification and threat detection — phishing, malware, botnet, spam, and inappropriate-content categories — that other network security, endpoint security, ad-tech, and service-provider companies embed into their own offerings. The company markets a partner traffic network described as covering roughly a billion users and endpoints, a scale claim that is vendor-reported and not independently audited.

As a small, publicly traded micro-cap operating in a mature, largely commoditized URL-filtering category, Zvelo’s relevance today is narrower than in the early web-filtering era; its long OEM relationships with unnamed “leading vendors” suggest real technical vetting by sophisticated buyers, but the company discloses little independently verifiable detail about current growth or customer names.
