AI Agent Sandbox and Prompt Injection Firewall

P7/10March 5, 2026
WhatA security layer that sits between AI coding agents and system resources, detecting and blocking prompt injection attacks in real-time before commands execute.
SignalDevelopers are giving AI agents like Cline and Claude Code broad system access via GitHub Actions and IDE integrations, but there is zero sanitization of untrusted inputs like issue titles flowing into agent prompts, creating a massive attack surface that compromised thousands of machines.
Why NowAI coding agents went from novelty to daily workflow tools in 2025-2026, and the attack surface of prompt injection through CI/CD pipelines and issue trackers is brand new and completely undefended.
MarketEvery company running AI-assisted development workflows (millions of developers); sells to DevSecOps teams and platform engineering orgs. Competitors like Snyk and Wiz cover traditional AppSec but have no prompt injection detection. TAM $5B+ as subset of application security market.
MoatFirst-mover data advantage — every blocked attack trains the detection model, creating a flywheel where the product gets better with scale. Deep integration into CI/CD pipelines creates switching costs.
