Backline is a cybersecurity company focused on autonomous vulnerability remediation at enterprise scale. The company positions its platform at the intersection of Dynamic Attack Surface Reduction (DASR) and Agentic Remediation, targeting the gap between vulnerability detection and actual resolution. Rather than providing additional scanning or alerting capabilities, Backline's platform is designed to perform the actual work of fixing vulnerabilities. The platform uses autonomous AI agents that analyze, prioritize, plan, and execute vulnerability fixes — moving beyond traditional ticketing and queue-based remediation workflows. Key platform capabilities include: - Preemptive, continuous, and dynamic vulnerability management - Autonomous agents that perform active remediation rather than passive detection or suggestion - Continuous attack surface minimization - Enterprise-scale deployment The company's founders previously built Whitebox Security (acquired by SailPoint) and Apolicy (acquired by Sysdig), with backgrounds in cloud security and application security. Backline is backed by investors including Evolution Equity Partners and Stage One. Backline targets enterprise security teams that are overwhelmed by vulnerability backlogs and seeks to automate the remediation lifecycle — from detection through safe, verified fixes — reducing operational burden and risk exposure associated with unresolved vulnerabilities.
