Ghost Security

Ghost Security, founded in 2022 and headquartered in Austin, Texas, emerged from stealth with $15 million in combined seed funding from 468 Capital, DNX Ventures, and Munich Re Ventures at a $50 million valuation. The company builds AI-driven application and API security tooling, and has since introduced "Exorcist," an autonomous agent that parses source repositories, controllers, routes, and handlers to build API inventories and generate actionable vulnerability remediation plans, including for APIs buried in microservices or serverless functions.

Ghost Security’s pitch is explicitly agentic: rather than only flagging findings, its platform aims to discover, test, and help remediate application and API risk with less manual triage, aligning it with the broader 2025-2026 shift toward AI agents embedded directly in security operations workflows. The platform supports SOC 2 and ISO 27001-aligned deployments with audit trails and SBOM export, and can run in cloud, on-premises, or air-gapped environments.

Public funding data shows no disclosed round since the August 2022 seed, which for a fast-moving AI-security startup is worth watching as a momentum signal even though the company continues to ship product (Exorcist launched well after the initial raise). For CISOs and AppSec leaders facing sprawling, poorly inventoried API surfaces, Ghost Security’s agentic discovery-and-remediation approach is a genuinely differentiated angle versus traditional SAST/DAST scanners, though efficacy claims are currently vendor-stated and not independently benchmarked.
