Backslash Security
Reachability-aware AppSec now aimed at AI coding agents, IDEs, MCPs, and the packages they pull.
Proof of life. Raised $19M Series A led by KOMPAS VC, February 2026
About Backslash Security
Backslash started as code-to-runtime reachability so SCA noise dropped to the 5% that is actually called.
The 2026 Series A reframes that as vibe-coding security: the agent, the IDE, the MCP, and the dependency it just added are one attack surface.
If your pipeline risk is 'Cursor installed a package at 2am', this is the scanner built for that moment.
