- Passwords are still weak so we recommend that your organization deploy Credential Guard and move away from passwords and to other authentication methods, such as physical smart cards, virtual smart cards, Microsoft Passport, or Microsoft Passport for Work. - Passwords are still weak so we recommend that your organization deploy Credential Guard and move away from passwords and to other authentication methods, such as physical smart cards, virtual smart cards, Microsoft Passport, or Microsoft Passport for Work.
- Some 3rd party Security Support Providers (SSPs and APs) might not be compatible with Credential Guard. Credential Guard does not allow 3rd party SSPs to ask for password hashes from LSA. However, SSPs and APs still get notified of the password when a user logs on and/or changes their password. Any use of undocumented APIs within custom SSPs and APs are not supported. We recommend that custom implementations of SSPs/APs are tested against Credential Guard to ensure that the SSPs and APs do not depend on any undocumented or unsupported behaviors. For example, using the KerbQuerySupplementalCredentialsMessage API is not supported. You should not replace the NTLM or Kerberos SSPs with custom SSPs and APs. For more info, see [Restrictions around Registering and Installing a Security Package](http://msdn.microsoft.com/library/windows/desktop/dn865014.aspx) on MSDN. - Some 3rd party Security Support Providers (SSPs and APs) might not be compatible with Credential Guard.

- As the depth and breadth of protections provided by Credential Guard are increased, subsequent releases of Windows 10 with Credential Guard running may impact scenarios that were working in the past. For example, Credential Guard may block the use of a particular type of credential or a particular component to prevent malwar efrom taking advantage of vulnerabilities. Therefore, we recommend that scenarios required for operations in an organization are tested before upgrading a device that has Credential Guard running. - As the depth and breadth of protections provided by Credential Guard are increased, subsequent releases of Windows 10 with Credential Guard running may impact scenarios that were working in the past.

- If you are using Wi-Fi and VPN end points that are based on MS-CHAPv2, they are subject to similar attacks as NTLMv1. We recommend that organizations use certificated-based authentication for Wi-Fi and VPN connections.

### NTLM & CHAP Considerations
When you enable Credential Guard, you can no longer use NTLM v1 authetnication. If you are using Wi-Fi and VPN end points that are based on MS-CHAPv2, they are subject to similar attacks as NTLMv1. We recommend that organizations use certificated-based authentication for Wi-Fi and VPN connections.

### Kerberos Considerations ### Kerberos Considerations
When you enable Credential Guard, you can no longer use Kerberos unconstrained delegation. Unconstrained delegation could allow attackers to extract Kerberos keys from the isolated LSA process. You must use constrained or resource-based Kerberos delegation instead. When you enable Credential Guard, you can no longer use Kerberos unconstrained delegation or DES encryption.

With the increase of employee-owned devices in the enterprise, there’s also an increasing risk of accidental data leak through apps and services, like email, social media, and the public cloud, which are outside of the enterprise’s control. For example, when an employee sends the latest engineering pictures from their personal email account, copies and pastes product info into a tweet, or saves an in-progress sales report to their public cloud storage.

Windows Information Protection (WIP) helps to protect against this potential data leakage without otherwise interfering with the employee experience. WIP also helps to protect enterprise apps and data against accidental data leak on enterprise-owned devices and personal devices that employees bring to work without requiring changes to your environment or other apps. Finally, another data protection technology, Azure Rights Management also works alongside WIP to extend data protection for data that leaves the device, such as when email attachments are sent from an enterprise aware version of a rights management mail client.
