Virtually Testing Foundation | 42,989 followers on LinkedIn. We learn through research, test through real-world response, and share through trusted community leadership. | Virtually Testing Foundation (VTF) is a 501(c)(3) nonprofit, invite-only cybersecurity research and incident response community. We bring together a global network of elite security professionals to lead original threat hunting research, provide rapid cyber incident response for nonprofit organizations, and host public and private events that drive collaboration, leadership, and technical excellence. VTF was created to fill a critical gap—nonprofit and mission-driven organizations are increasingly targeted by cyberattacks but often lack the resources to respond.
