Backline, an autonomous security remediation platform, launched from stealth with $9 million in Seed funding led by StageOne Ventures, with participation from Evolution Equity Partners and Gradient.
Backline’s AI agents automatically fix security vulnerabilities and misconfigurations at scale, helping enterprises tackle their overwhelming security backlogs. Already deployed across many organizations, Backline’s agents safely implement verified code and configuration changes while working alongside existing security and engineering teams.
Enterprises are challenged with many security issues, with new vulnerabilities being discovered at an unprecedented rate. And existing security tools are effective at detection and prioritization, but this approach cannot scale — organizations lack the resources to address even their most severe security findings.
Backline’s autonomous security remediation platform deploys a fleet of AI agents that work to tackle this backlog at scale. And the agents step into the shoes of security and software engineers, analyzing security findings, gathering necessary context, determining optimal fixes for the specific environment, and implementing verified code and configuration changes that customers can trust. The platform is designed for autonomous operation while maintaining complete control — teams can choose their preferred level of oversight and automation based on their specific needs and requirements.
This platform integrates seamlessly with organizations’ existing security tools, consolidating findings into a centralized security findings lake. And at its core, Backline uses AI-native remediation playbooks — deterministic and verified recipes purpose-built and designed for AI agents — which are also further enriched with customer-specific context.
These playbooks also ensure consistent, high-quality fixes that mitigate the unpredictability of out-of-the-box foundational LLMs. And when agents encounter scenarios that need additional input, they automatically engage relevant engineers through tools like Jira, Slack, and GitHub. This feedback loop continuously improves the platform’s autonomous capabilities while maintaining complete visibility and control over the remediation process.
KEY QUOTES:
“Engineering teams spend over 20% of their time fixing security issues, but that barely covers the most critical ones. They wake up each day to hundreds of new issues — not because anything changed overnight, but simply due to newly discovered vulnerabilities or weaknesses in cloud services they are using. This has led to endless prioritization and perpetually growing backlogs of ‘lower-priority’ issues. The frustrating reality is that most breaches stem from known security issues — often simple to fix, but buried deep in backlogs that developers, DevOps, and platform engineers will never find time to address.”
- Maor Goldberg, co-founder and CEO of Backline
“Security backlogs are now the number one thing keeping CISOs up at night. Backline’s deep cybersecurity expertise combined with their vision for autonomous remediation present a way out of the prioritization paradigm through multiple orders of magnitude improvement in remediation velocity. We haven’t talked to a single organization that claims to have their security backlog fully under control, which signals just how significant this opportunity is.”
- Tal Slobodkin, Managing Partner at StageOne Ventures, who also backed the founding team’s previous startup
“Security backlogs are a burden that must be addressed at every company. We’re excited about how Backline’s autonomous security remediation platform, with its unique agentic approach, can help us quickly deploy reliable code and configuration changes at scale to tackle this challenge.”
- Michael Bourgault, Senior Security Architect at Arkose Labs
“Organizations are drowning in security problems while existing security tools just describe the water. Backline represents a fundamental shift from endless prioritization to actual remediation. By deploying AI agents that can safely implement and verify fixes at scale, Backline ensures accuracy and trust — the critical foundation for successful enterprise adoption of AI systems.”
- Darian Shirazi, Managing Partner at Gradient
“As AI accelerates the discovery and exploitation of vulnerabilities, enterprises need a new approach to remediation that can match this pace. Trust in automation comes through verification, and Backline’s platform delivers exactly that — enabling autonomous remediation while ensuring every change is thoroughly tested and validated.”
- Yuval Ben-Itzhak, General Partner at Evolution Equity Partners
