An honest security examination of Bun as a newer JavaScript and TypeScript runtime built with different design goals than the established Node.js runtime. Covers why cumulative security scrutiny and track record matter, compatibility layer risk when a runtime reimplements another's behaviour, dependency and package installation security specific to a newer package manager implementation, the security surface introduced by bundling more built-in functionality including networking, file system and foreign function interface capability, monitoring and incident response readiness for a less mature surrounding ecosystem, migration risk when moving an existing application to a new runtime, and a practical, staged decision framework for weighing genuine performance and developer experience benefits against real maturity trade-offs.
Nothing. Every course, exam, and certificate on the catalog is free — including retakes. All you need is a free Safeguard account.
None. The flagship course, Safeguard Certified Practitioner, is a beginner-level course — basic familiarity with how software is built helps, but every exam question is answerable from the lessons themselves.
You can retake it after a 24-hour cooldown, as many times as you need. Retakes are free, and each attempt draws a fresh random set of questions.
The Safeguard Certified Practitioner credential is valid for 24 months from issue. The expiry date is printed on the certificate and shown live on its public verification page. Renewing means passing the current exam again.
