    About the safelink decoder

    Unwraps the rewritten links that email security gateways insert, recovering the real destination. Handles Microsoft Defender SafeLinks, both Proofpoint URL Defense versions and generic redirect parameters, then decodes any nested percent-encoding.

    Frequently asked questions

    Why unwrap a protected link at all?

    To see where it actually goes before clicking. The wrapper hides the destination host, which is precisely the detail you need when judging whether a message is a phishing attempt.

    Does unwrapping remove the protection?

    It only reveals the target — it does not disable scanning for anyone else. Visiting the unwrapped address does bypass the gateway's click-time check, so read the host carefully first.
