AI Security Verdict

Moderate Risk

Confidence: 78%

5
Risk Score

Redirect from a Firebase subdomain lands on Santander UK's genuine site; no credential/payment forms, no malware or threat-intel hits. Destination is the real brand domain, so only the obfuscated entry link warrants mild caution.

Risk Factors (2)
Entry host failed-recipient-add.web.app is a free Firebase hosting subdomain whose actual creation date is unknown and whose content/lifetime cannot be verified.
Cross-domain redirect from an unrelated-looking Firebase hostname into a bank site can be used in link-obfuscation campaigns, even though the destination served here is genuine.
Safety Factors (2)
Final destination is Santander UK's own official domain (www.santander.co.uk), reached by redirect — not a lookalike or typosquat.
Cross-origin traffic is limited to well-known analytics/consent providers and is not tied to credential handling.
