Sprocket Security delivers continuous penetration testing for enterprises, combining ongoing offensive security assessments with real-time risk monitoring and remediation. It uses a hybrid model that blends human security experts with automated systems to run adversary simulations and attack surface management on an ongoing basis, all billed via a subscription. The product works by continuously testing an organization’s defenses, monitoring for new risks in real time, and providing guided remediation to reduce exposure, rather than performing one-off tests. This approach sets the company apart from competitors by offering year-round, persistent testing and monitoring instead of periodic checks, ensuring vulnerabilities are addressed proactively. The goal is to help enterprises maintain a strong, resilient cybersecurity posture by continuously identifying and mitigating threats before they can be exploited.
