Backline, the cutting-edge autonomous security remediation platform, has officially launched with $9 million in Seed funding. The round was led by StageOne Ventures, with participation from Evolution Equity Partners and Gradient. Backline’s innovative fleet of AI agents automatically resolves security vulnerabilities and misconfigurations at scale, helping enterprises tackle the growing and overwhelming security backlogs they face. Already deployed across multiple organizations, Backline’s agents work seamlessly with existing security and engineering teams to implement verified code and configuration changes safely.
As organizations grapple with an explosion of new security vulnerabilities, the need for scalable solutions has never been more pressing. In 2024 alone, more than 40,000 new CVEs were reported, averaging one new vulnerability every 13 minutes. While current security tools excel in detection and prioritization, they are ill-equipped to address the scale of the problem — leaving organizations struggling to manage and resolve even the most critical security issues.
“Engineering teams spend over 20% of their time fixing security issues, but that barely covers the most critical ones,” said Maor Goldberg, co-founder and CEO of Backline. “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 the cloud services they are using. This leads 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 never find time to address.”

Backline’s autonomous security remediation platform is designed to tackle this challenge head-on by deploying AI-powered agents that take on the heavy lifting of security remediation at scale. These agents step into the roles of security and software engineers, analyzing security findings, gathering necessary context, and determining the most effective fixes tailored to each unique environment. The platform autonomously implements verified code and configuration changes, providing enterprises with reliable and secure remediation solutions. Teams can configure the platform to operate autonomously or maintain varying levels of oversight and control, depending on their specific needs.
“Security backlogs are now the number one thing keeping CISOs up at night,” said Tal Slobodkin, Managing Partner at StageOne Ventures, who also supported the founding team’s previous startup. “Backline’s deep cybersecurity expertise, combined with their vision for autonomous remediation, offers a way out of the prioritization paradigm. Their approach promises to improve remediation velocity by multiple orders of magnitude. 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.”
“Security backlogs are a burden that must be addressed at every company,” said Michael Bourgault, Senior Security Architect at Arkose Labs. “We’re excited about how Backline’s autonomous security remediation platform, with its unique agent-driven approach, can help us quickly deploy reliable code and configuration changes at scale to tackle this challenge.”
The Backline platform seamlessly integrates with organizations’ existing security tools, consolidating findings into a centralized security findings lake. At its core, Backline utilizes AI-native remediation playbooks — deterministic and verified recipes designed specifically for AI agents. These playbooks are enriched with customer-specific context to ensure that fixes are accurate, consistent, and of high quality. When agents encounter scenarios that require further input, they automatically engage relevant engineers via tools such as Jira, Slack, and GitHub. This feedback loop continuously enhances the platform’s autonomous capabilities, all while maintaining full visibility and control over the remediation process.
“Organizations are drowning in security problems, while existing tools just describe the water,” said Darian Shirazi, Managing Partner at Gradient. “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.”
“As AI accelerates the discovery and exploitation of vulnerabilities, enterprises need a new approach to remediation that can keep pace,” said Yuval Ben-Itzhak, General Partner at Evolution Equity Partners. “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.”
Backline’s platform addresses the growing need for scalable, trustworthy, and efficient solutions to security backlogs, helping organizations stay ahead of emerging threats while enabling their teams to focus on more strategic initiatives. The $9 million in Seed funding will enable Backline to expand its offerings and further enhance its platform, driving adoption and innovation in the security remediation space.
