More About NetSPI
NetSPI focuses on offensive security services for enterprises, with a portfolio centered on penetration testing, attack surface management (ASM), and red team operations. Its offerings are typically used by large enterprises, financial institutions, healthcare organizations, and other regulated or security-sensitive sectors that require structured, repeatable security testing at scale. The company positions its services as programmatic, often delivered on an ongoing basis rather than as one-time assessments, to support continuous security validation and governance.
NetSPI’s penetration testing services cover application security, network and infrastructure security, and cloud security (security testing). Engagements commonly align with enterprise architectures built on public cloud providers, containerized environments, and hybrid networks. The company tests web and mobile applications, APIs, internal and external networks, wireless environments, and emerging technology stacks such as IoT and Operational technology (OT) where applicable. These services typically map to security assessment and vulnerability management categories in enterprise IT taxonomies.
The attack surface management (ASM) offering (attack surface management) focuses on continuous external asset discovery, enumeration, and vulnerability identification. It supports organizations that operate large, distributed environments with multiple internet-facing domains, IP ranges, and cloud resources. Attack Surface Monitoring (ASM) is used to maintain an inventory of exposed assets, detect configuration weaknesses, and feed findings into enterprise vulnerability management, Security Information and Event Management (SIEM), or ticketing systems. This capability aligns with external attack surface management and exposure management categories.
NetSPI also delivers red teaming and adversary simulation (offensive security services), in which consultants emulate threat actor behavior to test detection and response capabilities. These engagements often map to MITRE ATT&CK tactics and techniques, and they are used by Security Operations (SecOps) center (SOC) teams and incident response functions to validate controls, logging, and alerting. In addition, NetSPI supports purple teaming exercises where offensive and defensive teams collaborate to tune detections and refine SecOps workflows.
Across these service lines, NetSPI typically integrates with enterprise processes such as DevSecOps pipelines, risk management frameworks, and compliance programs. Testing outputs are delivered through structured reporting, dashboards, and remediation guidance, which can connect into issue tracking, Governance, Risk, and Compliance (GRC) tools, or vulnerability management platforms used by clients. For marketplace and directory classification, NetSPI aligns with penetration testing services, red team services, external attack surface management, Application Security Testing (AST), and cloud security assessment categories that support CISOs, security architects, and infrastructure leaders.
