Safe Links is part of Microsoft Defender for Office 365. It rewrites links so Microsoft can evaluate destination safety when a user clicks. The original destination is embedded inside query parameters.
This decoder does not bypass security controls. It simply helps you inspect link destinations before visiting them.
Use this tool together with your email security workflow: decode first, then validate domain reputation before opening unknown links.
Decoding is only one step in link analysis. After extraction, validate domain age, reputation, and destination intent before interacting with unknown content.
Safe Links improve protection but can obscure destination readability in tickets and reports. A decoder restores transparency for analysts and support teams.
