Case Study: Mandiant (a Google company) achieves end-to-end SDLC visibility and faster remediation with Legit Security

Google Mandiant Securing the World’s Information

Mandiant, now part of Google, is a leading cybersecurity firm responsible for protecting customer‑facing products, internal applications and software supply chains. To preserve security without slowing innovation, Mandiant needed end‑to‑end visibility across the SDLC, integration with existing tools, reduced AppSec noise, and the ability to prioritize real risk—so they engaged Legit Security and its platform for real‑time SDLC monitoring, customizable guardrails, and consolidated vulnerability visibility.

Legit Security integrated with Mandiant’s CI/CD pipelines and Jira to centralize findings, apply environment‑specific risk ratings, automatically open contextual remediation tickets, and trace root causes. Those capabilities lowered MTTR and reduced alert fatigue—for example, a single root‑cause fix enabled engineers to remediate 160 related XSS issues in 15 minutes instead of chasing each one—giving Mandiant faster detection, clearer prioritization, and better collaboration between AppSec and engineering.
