Guardsquare App Attestation vs Promon Shield for Mobile™: Side-by-Side Comparison (2026)

Guardsquare App Attestation

Mobile app teams defending APIs against forged clients and tampered apps will benefit most from Guardsquare App Attestation because it verifies app integrity server-side without requiring app updates to change security policies. The tool covers both iOS and Android with cryptographically signed attestation tokens and detects rooted devices, emulators, and hooking frameworks in real time. Skip this if your threat model assumes users control their own devices; Guardsquare's value drops sharply when you can't enforce device posture as a gating condition.

Promon Shield for Mobile™

Mobile teams at mid-market and enterprise organizations should pick Promon Shield for Mobile™ if reverse engineering and tampering are your actual threat model, not theoretical ones. Post-compile integration means you inject protection without touching source code or rebuilding your CI/CD pipeline, which matters when you're shipping iOS and Android apps on existing schedules. The tool covers rooted and jailbroken devices with on-device AI models, addressing threats most mobile solutions ignore until your app is already compromised. Skip this if your mobile security concern is primarily data leakage from misconfigured APIs; Promon is built for runtime threats, not backend hardening.
