    Hi all,

     

    found a solution. If anyone is also interested in installing Google Chrome Enterprise with Intune as MSI and have also Windows Defender fully activated

    -------

    especially ExploitGuard & CredentialGuard or at least the option in the Intune Endpoint Protection Profile >> Endpoint protection > Windows Defender Exploit Guard > Attack Surface Reduction > Flag credential stealing from the Windows local security authority subsystem = Enable

    -------

    Here is the Mitigation.xml which is working (working - not perfect)

    Intune Endpoint Protection Profile >> Endpoint protection > Windows Defender Exploit Guard > Exploit protection

    <?xml version="1.0" encoding="UTF-8"?>
    <MitigationPolicy>
    <AppConfig Executable="GoogleUpdate.exe">
    <DEP Enable="true" EmulateAtlThunks="false" />
    <ASLR ForceRelocateImages="false" RequireInfo="false" BottomUp="true" HighEntropy="true" />
    <StrictHandle Enable="false" />
    <SystemCalls DisableWin32kSystemCalls="false" />
    <ExtensionPoints DisableExtensionPoints="false" />
    <DynamicCode BlockDynamicCode="false" AllowThreadsToOptOut="false" />
    <ControlFlowGuard Enable="true" SuppressExports="false" />
    <SignedBinaries MicrosoftSignedOnly="false" AllowStoreSignedBinaries="false" EnforceModuleDependencySigning="false" />
    <Fonts DisableNonSystemFonts="false" AuditOnly="false" Audit="false" />
    <ImageLoad BlockRemoteImageLoads="false" BlockLowLabelImageLoads="false" />
    <Payload EnableExportAddressFilter="false" EnableExportAddressFilterPlus="false" EnableImportAddressFilter="false" EnableRopStackPivot="false" EnableRopCallerCheck="false" EnableRopSimExec="false" />
    <SEHOP Enable="true" TelemetryOnly="false" />
    <Heap TerminateOnError="true" />
    <ChildProcess DisallowChildProcessCreation="false" />
    </AppConfig>
    </MitigationPolicy>

    If anyone know which option allows the access to lassas.exe please reply.
