NowSecure ADA MASA vs Guardsquare App Attestation: 2026 Comparison

NowSecure ADA MASA

Android teams shipping to Google Play need NowSecure ADA MASA specifically because it's the only service that handles MASA certification and OWASP MASVS Level 1 validation in one workflow, eliminating the back-and-forth between compliance and security reviews. The tool covers six concrete security domains (data storage, cryptography, authentication, network communication, platform interaction, code quality) and includes a free smoke test before you commit to formal validation, which cuts wasted assessment cycles. This is the right choice for startups and mid-market shops that can't afford to hire dedicated mobile security staff; it's not built for large enterprises with in-house AppSec teams who need deeper custom testing or continuous integration across iOS and Android simultaneously.
