ESProfiler by ESProfiler is a Continuous Security Investment Validation (CSIV) platform designed to optimize security spend and maximize return on investment. It addresses the challenges of tracking security products used by multiple business units by embedding into the procurement process to continually track security-related contracts. ESProfiler indexes contracts, providing a clear view of products owned, their expiration dates, and costs. It quantifies security products against attacker operations based on frameworks like MITRE ATT&CK® and NIST, combining security controls with quantified capabilities to offer a comprehensive understanding of security investments. ESProfiler relates product features to security capabilities and uses automated usage data to identify unused products and features, helping to maximize the value from security assets by highlighting gaps and overlaps. It integrates into post-incident reviews and breach attack simulations to connect incident descriptions to relevant capabilities, offering a holistic view of security effectiveness. ESProfiler is available as a cloud or hybrid-on-premise solution, designed to break down silos in security, prioritize threats, and optimize security spend and posture. It includes enterprise-grade features such as dedicated compute/storage, auditing, 2FA, enterprise sign-on, and full extensibility through advanced APIs. The platform supports every stage of the security lifecycle, from RFI/RFP's and procurement to project delivery and ongoing value realization. It integrates directly with the Capability Exchange, a living catalogue of security products and features with associated capabilities, and offers unlimited integrations through an enterprise-ready integration engine.
