StepSecurity published a case study describing Arcjet adopting StepSecurity’s Harden-Runner to protect GitHub Actions workflows.
Summary: The case study describes measures to protect CI/CD workflows from exfiltration-style attacks and includes commentary attributed to Arcjet leadership.
Critical evaluation: This case study focuses on StepSecurity’s offering and therefore has inherent marketing bias. It does provide detail about Arcjet’s internal CI/CD security posture and suggests Arcjet addresses CI/CD security needs.
Arcjet is an application security SDK that integrates with application code and is intended to be embedded in an application’s request-handling path (e.g., Next.js/Node handlers). It focuses on abuse and bot-driven threats such as:
Arcjet positions its approach as configuring security alongside application logic rather than relying only on edge (CDN/WAF) or perimeter controls. The company also describes an opt-in local AI model intended to run analysis within a customer's environment while also offering cloud enrichment.
Evidence: Arcjet describes the product as a security platform that is integrated with application code, with features including bot detection, rate limiting, email validation, attack protection, and data redaction. The company states that its local AI model can perform analysis locally.
