Value
|
Proof
|
Comment
|
| Known hardware tampering
|
None
|
🔗 Proof
|
No public G99E5-specific hardware tampering found in reviewed sources; this is not proof of immunity to physical access.
|
| Known vulnerabilities
|
None
|
🔗 Proof
|
DEKRA reports tested G99E5 firmware up to date with public software/hardware vulnerabilities; no G99E5-specific CVE identified in reviewed sources.
|
| Prior attacks
|
None
|
🔗 Proof
|
No public G99E5-specific successful attack found in reviewed Google security bulletins; absence of a report is not proof none occurred.
|
| Updatability
|
Very common
|
🔗 Proof
|
Google lists automatic security updates through at least 25 Jun 2031; DEKRA verifies signed OTA updates over TLS.

Secure
|
🔗 Proof
|
DEKRA confirms 2FA for the Google Home app and certificate-based service authentication.
|
| Brute-force protection
|
Basic
|
🔗 Proof
|
Basic: Google flags unfamiliar sign-ins and may require an extra identity step; G99E5-specific rate limiting was not documented.
|
| Event logging
|
Partial logging
|
🔗 Proof
|
DEKRA confirms cloud-managed event logging, but does not establish a complete user-visible device access log.
|
| Passwords
|
Require change after setup with complexity requirements
|
🔗 Proof
|
Closest rubric option: no factory default speaker password; a Google Account password is user-created and weak or reused passwords are rejected. No mandatory post-setup change is documented.

Scope: 2026 Google Home Speaker, hardware G99E5, not the original 2016 Google Home. DEKRA assessed firmware T171800. Scores of None for tampering, vulnerabilities and attacks reflect absence of public G99E5-specific evidence in sources reviewed on 23 Oct 2026, not proof such events cannot occur. The password option is an imperfect fit for account-based setup; no mandatory password change after setup is documented.
