NetSPI

Overview

NetSPI sells penetration testing through the NetSPI Platform, which supports penetration testing as a service (PTaaS), attack surface management and breach and attack simulation as a service^[5]. It positions its PTaaS as shifting penetration testing from one-off projects to programmes, with human-delivered, contextualised testing^[5].

The firm says its customers include large cloud providers, top US banks, large healthcare companies and major technology companies, and shows logos including Microsoft, Chubb and Broadridge^[5]. Its service catalogue covers application, cloud, network and other assessments, delivered by dedicated security experts using a process it calls the NetSPI Advantage^[5].

NetSPI combines a platform with in-house testers rather than a crowd, which suits regulated buyers that require vetted employees. It runs a partner programme for channel and technology partners^[5]. Pricing is not published.
