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.
