What LIVERTON SECURITY (UK) LIMITED does

Liverton Security (UK) Limited is a privately held cybersecurity software and services firm headquartered in London, United Kingdom. The company sells a portfolio of email-centric security products—SmartGate (email threat filtering), MailAdviser (DLP integrated with Microsoft Outlook), SHIFT for Outlook (secure large file transfer), WebAdviser AI (generative AI data safety), SEEMail/SGE Plus (government secure email aligned with NZ ISM / PSR), and LiveDNS (self-service DNS and domain management)—complemented by a professional consulting line that includes penetration testing, security maturity assessments, and Virtual CISO engagements.

The commercial model is a hybrid of subscription-based SaaS for software products and project- or retainer-based fees for consulting. Pricing is not publicly disclosed and follows a quote-based structure tailored to the customer's organization size, sector, and risk profile. Distribution combines direct enterprise field sales (anchored by "Get A Demo" calls-to-action), curated marketplace listings on Microsoft AppSource and the New Zealand Government Marketplace, and consulting-led engagement. Most products are architected to plug into the Microsoft Outlook and Exchange environment, which is a deliberate platform bet.

The disclosed customer base skews toward New Zealand public-sector and regulated clients (NZ Government agencies, NZ Defence Force, Ministry of Business, Innovation & Employment, Reserve Bank of New Zealand), alongside commercial accounts in legal (Gill Jennings & Every), innovation (Plexal), hospitality (Maybourne Hotel Group), healthcare (Pharmac), and financial services / research (Nomura Research Institute, Indonesia). The company holds an ISO 27001 certification issued by Telarc and reports more than 20 years of operating history, a user base of over 100,000 worldwide, and more than 30 million emails processed per month across its customer base. The founding year is inconsistent across sources—one dataset lists 2022, while company history and the "more than 20 years" claim are consistent with a circa-2004 origin, which is the operative figure for analytical purposes.
