NetSPI Reviews, Ratings & Features 2026 | Gartner Peer Insights

Gartner defines adversarial exposure validation (AEV) as technologies that deliver consistent, continuous and automated evidence of the feasibility of an attack. These technologies confirm how potential attack techniques would successfully exploit an organization and circumvent prevention and detection security controls. They achieve this by performing attack scenarios and modeling or measuring the outcome to prove the existence and exploitability of exposures. AEV is generally delivered as a SaaS solution with or without on-premises agents. AEV as a market category replaces breach and attack simulation (BAS) and automated penetration testing and red teaming technology from the 2023 Gartner Hype Cycle (Hype Cycle for Security Operations, 2023). AEV technologies provide automated execution of both simplified and/or extensible attack scenarios. Results data from an executed attack scenario is used for various outcomes, such as:
validating a theoretical exposure as real,
automating frequent controls testing,
improving preventive security posture
or improving detection and response capabilities.

I have done 1 pentesting for 2 web applications deployed in the Cloud (PaaS and IaaS) with NetSpi. The project went smoothly, the pentester engaged well with our team and it was fairly priced. After trying a few vendors over the years, I have decided they will be our recommended partner for pentesting moving forward.
