About Pi
At a glance
Pi is a cybersecurity company specializing in Application Security. It is privately held.
Pi is an application security platform designed to help software development teams reduce recurring vulnerabilities and maintain development velocity. The platform operates by ingesting and indexing an organization's codebase, historical security incidents, penetration testing reports, and issue tickets to build what it calls an "institutional security memory." Core capabilities include: - Root cause analysis: Pi traces vulnerabilities to their architectural source rather than treating each instance individually, enabling it to detect and close entire classes of vulnerabilities at once. - Variant detection: After identifying a root cause, Pi scans the entire codebase for related variants across all teams and services. - Contextual remediation: Fixes are generated in the context of the organization's specific languages, architecture, and coding conventions, and are delivered directly into developer workflows. - Prevention guardrails: Learnings from past vulnerabilities are converted into enforcement rules applied within IDEs and pull request workflows, blocking known insecure patterns before code reaches production. - AI security assistant: Pi includes an assistant called Sloane, which can answer questions about the codebase and the organization's security history. Pi targets engineering and security teams at organizations that ship software at high velocity. The platform integrates with existing developer tools and is positioned to reduce manual triage workload, decrease repeat vulnerability payouts in bug bounty programs, and improve overall security posture over time. Customers listed include Lemonade, Teramind, and Navan. Pi holds SOC 2 certification.
