Specify the TLS cipher suites to disable
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 85, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
Configure the list of cipher suites that are disabled for TLS connections. If you configure this policy, the list of configured cipher suites won't be used when establishing TLS connections. If you don't configure this policy, the browser chooses which TLS cipher suites to use. Cipher suite values to be disabled are specified as 16-bit hexadecimal values. The values are assigned by the Internet Assigned Numbers Authority (IANA) registry. The TLS 1.3 cipher suite TLS_AES_128_GCM_SHA256 (0x1301) is required for TLS 1.3 and can't be disabled by this policy. This policy does not affect QUIC-based connections. QUIC can be turned off via the 'QuicAllowed' (Allow QUIC protocol) policy. Example value: 0x1303 0xcca8 0xcca9

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
