Arm

Arm's AppSec philosophy is rooted in embedding security throughout the design, development, and verification processes via a Security Development Lifecycle (SDL) to identify and mitigate risks early. They also maintain a Product Security Incident Response Team (PSIRT) dedicated to identifying, assessing, and mitigating vulnerabilities. Proactive testing and partnerships with application security testing (AST) solution providers like CodeSecure (formerly GrammaTech) are integral to their approach.

Recent company job postings and official developer security documentation indicate Arm is actively building AI-driven security tooling (including AI-driven code reviews and noise reduction) and coordinates multi-stakeholder vulnerability mitigation — signals that point to triage/load and remediation coordination challenges as developer-facing security tooling expands. Evidence includes a 2025 Arm job posting explicitly calling out AI-driven security code reviews and noise reduction, Arm’s vulnerability disclosure guidance describing multi-stakeholder mitigation and coordinated disclosure, and a 2025 Arm newsroom post describing AI-enabled developer training.

Arm implements a Security Development Lifecycle (SDL) to embed security early in design, development, and verification. They also operate a Product Security Incident Response Team (PSIRT) for vulnerability management, including identification, assessment, and mitigation. Proactive testing and strategic partnerships with application security testing vendors, such as CodeSecure (formerly GrammaTech), are key initiatives.

Arm is a company with 5,001-10,000 employees. While the LinkedIn page identifies the company size, specific AppSec team size or key leaders were not directly extractable from the provided inputs or initial web findings. The careers site lists open roles, but AppSec-specific job counts would require a live query.
