NCC Group Continuous Offensive Security is a managed security service that provides ongoing penetration testing and vulnerability assessment capabilities. The service operates continuously rather than at scheduled intervals, integrating into development cycles and DevSecOps workflows. The offering includes three primary service components: Continuous Offensive Penetration Testing for web applications, web services, APIs, and mobile applications; Attack Surface Management for continuous asset discovery and vulnerability identification informed by threat intelligence; and break-glass penetration testing for rapid assessment of zero-day threats. The service combines automated testing with expert consultant analysis to identify and assess vulnerabilities. Consultants engage directly with client teams to provide context and respond to critical findings. Results are delivered through a dashboard and integrated directly into DevSecOps toolchains for real-time visibility. The service operates on a predictable monthly cost model, converting penetration testing from capital expenditure to operational expenditure. It aligns testing with industry standards including OWASP and NIST frameworks. NCC Group positions this as an alternative to traditional point-in-time penetration testing, providing continuous monitoring and assessment that matches the pace of modern development cycles.
