About this page
Norton URL Checker (Reference) is a static, client-side tool with no backend. Norton URL Checker (Reference) runs structural and look-alike phishing heuristics on a URL, inspecting scheme, host, embedded credentials, punycode look-alikes, suspicious TLDs and obfuscated encoding.
Norton URL Checker (Reference) is deliberately honest about its limits: it highlights risk signals, it does not certify a link as safe. It behaves the same on desktop and mobile, with nothing stored remotely.
