Strategic Funding OnSecurity recently secured multi-million funding rounds (approximately £5.5M / $7M) from notable investors, signaling strong growth momentum and an expanding operational footprint that sales teams can leverage to position premium pentesting services to mid-market and enterprise clients seeking scalable security solutions.

AI Augmented Pentesting The company emphasizes AI-augmented penetration testing delivered through CREST accreditation, presenting a unique selling point for customers prioritizing rigorous security assessment with efficiency gains, enabling upsell opportunities to organizations needing faster risk remediation and compliance readiness.

Growth Traction With revenue in the active range of several tens of millions of dollars and a growing headcount, OnSecurity demonstrates market demand and scalability; this supports cross-sell of related security services, managed services, and continuous monitoring packages to existing pentest clients.

Tech Stack & Accessibility A modern tech footprint (Vue.js, Nmap, web and form technologies) paired with a cloud-ready, scalable delivery model suggests potential for offering automated assessment tools, developer-friendly integrations, and API-driven services to attract tech-forward security teams.
