Visit Website ↗ + Add to Compare Claim This CompanyOverview
SafeStack, founded in 2018 and based in Auckland, provided secure-coding and application-security training for developers, helping organizations reduce vulnerabilities introduced earlier in the software development lifecycle rather than relying solely on downstream scanning.
NINJIO acquired it in July 2026 to extend its human risk management platform deeper into the development lifecycle.
Innovation Matrix Assessment
Maintained a focused secure-coding training product for roughly eight years prior to acquisition, a steady rather than fast-cycle pace typical of training-content vendors.
Reduces vulnerabilities introduced earlier in the SDLC by training developers directly, complementing downstream AppSec scanning tools.
Acquired by NINJIO in July 2026 to extend its human risk management platform into secure coding, though deal terms were undisclosed.
Developer secure-coding training is an established sub-category of security-awareness training; SafeStack's focus is a useful specialization rather than a new category.
Sustained operation and acquisition by an established training platform are reasonable indirect signals, though no independent efficacy data was found.
Shifting security education earlier into the developer workflow remains a relevant complement to AppSec tooling as secure-by-design practices gain emphasis.
Why CISOs Should Care
SafeStack provided purpose-built secure-coding and application-security training for developers, giving CISOs a way to reduce vulnerabilities introduced earlier in the software development lifecycle rather than relying solely on downstream scanning.
What Makes It Different
Focused specifically on developer-facing secure-coding education (as opposed to general employee security-awareness training), now folded into NINJIO's broader human risk management platform.
The Matrix Verdict
42/100 — EMERGING / UNRANKED
A focused, roughly eight-year-old secure-coding training specialist acquired by NINJIO in July 2026 to extend human risk management deeper into the software development lifecycle.
