What Virus Bulletin does
Virus Bulletin Ltd is a privately held UK security information and testing company founded in 1989 and registered in England and Wales (company number 2388295), headquartered in Wallingford with 11–50 employees. The company provides independent testing, certification, and threat intelligence services for the cybersecurity industry, built around four certification programs: VB100 (Windows endpoint anti-malware efficacy), VBSpam (email security solutions), VBWeb (web security gateways), and VB ESA-M365 (Microsoft 365 email security add-ons, with inaugural results published in June 2026). Its testing methodologies combine reproducible frameworks (e.g., VBWeb's cached/replayed traffic and case-level classification, WildList-based detection sampling for VB100, AMTSO-aligned execution for VBSpam) with both public comparative reports and private consultancy engagements for individual vendors.
The business operates a community-led, multi-revenue-stream model. Revenue is generated from vendor participation fees in testing programs (both public certification tests and private consultancy engagements), ticket sales and tiered sponsorship (Platinum/Gold/Bronze) for the annual VB Conference (running since 1991 and rotating across European and North American cities, with VB2025 in Berlin and VB2026 scheduled for Seville), newsletter and Bulletin subscriptions (with archives extending back to 1989), and registered extranet memberships. The Bulletin serves as a peer-reviewed publication channel, and the Péter Szőr Award — an annual recognition for best technical security research — anchors community engagement with vendors such as Palo Alto Networks Unit 42, ESET, Sophos, Cisco Talos, Kaspersky, and Fox-IT.
Distribution is predominantly digital, anchored by virusbulletin.com, extranet.virusbulletin.com, and the vblocalhost.com virtual conference platform, with transactional processing handled by Elavon and email infrastructure by Google G Suite and Brevo. The firm operates with no disclosed venture funding, no parent company, and no subsidiaries, indicating a self-sustaining independent operating model.
