Learn about Microsoft Entra Internet Access for all apps
Microsoft Entra Internet Access provides an identity-centric Secure Web Gateway (SWG) solution for Software as a Service (SaaS) applications and other Internet traffic. It protects users, devices, and data from the Internet's wide threat landscape with best-in-class security controls and visibility through Traffic Logs.
Web content filtering
The key introductory feature for Microsoft Entra Internet Access for all apps is Web content filtering. This feature provides granular access control for web categories and Fully Qualified Domain Names (FQDNs). By explicitly blocking known inappropriate, malicious, or unsafe sites, you protect your users and their devices from any Internet connection whether they're remote or within the corporate network.
When traffic reaches Microsoft's Secure Service Edge, Microsoft Entra Internet Access performs security controls in two ways. For unencrypted HTTP traffic, it uses the Uniform Resource Locator (URL). For HTTPS traffic encrypted with Transport Layer Security (TLS), it uses the Server Name Indication (SNI).
Web content filtering is implemented using filtering policies, which are grouped into security profiles, which can be linked to Conditional Access policies. To learn more about Conditional Access, see Microsoft Entra Conditional Access.
Note
While web content filtering is a core capability for any Secure Web Gateway, similar capabilities exist in other security products, such as endpoint security products like Microsoft Defender for Endpoint and firewalls like Azure Firewall. Microsoft Entra Internet Access provides additional security value via policy integration with Microsoft Entra ID, policy enforcement on the cloud edge, universal support for all device platforms, and future security enhancements through Transport Layer Security (TLS) Inspection, such as higher fidelity web categorization. Learn more in the FAQ.
Security profiles
Security profiles are objects you use to group filtering policies and deliver them through user aware Conditional Access policies. For instance, to block all News websites except for msn.com for user angie@contoso.com you create two web filtering policies and add them to a security profile. You then take the security profile and link it to a Conditional Access policy assigned to angie@contoso.com.
"Security Profile for Angie" <---- the security profile
Allow msn.com at priority 100 <---- higher priority filtering policies
Block News at priority 200 <---- lower priority filtering policy
Policy processing logic
Within a security profile, policies are enforced according to logical ordering of unique priority numbers, with 100 being the highest priority and 65,000 being the lowest priority (similar to traditional firewall logic). As a best practice, add spacing of about 100 between priorities to allow for policy flexibility in the future.
Once you link a security profile to a Conditional Access (CA) policy, if multiple CA policies match, both security profiles are processed in priority ordering of the matching security profiles.
Important
The baseline security profile applies to all traffic even without linking it to a Conditional Access policy. It enforces policy at the lowest priority in the policy stack, applying to all Internet Access traffic routed through the service as a 'catch-all' policy. The baseline security profile executes even if a Conditional Access policy matches another security profile.
Known limitations
- Platform assumes standard ports for HTTP/S traffic (ports 80 and 443).
- IPv6 isn't supported on this platform yet.
- UDP isn't supported on this platform yet.
- User-friendly end-user notifications are in development.
- Remote network connectivity for Internet Access is in development.
- Transport Layer Security (TLS) termination is in development.
- URL path based filtering and URL categorization for HTTP and HTTPS traffic are in development.
- Currently, an admin can create up to 100 web content filtering policies and up to 1,000 rules based on up to 8,000 total FQDNs. Admins can also create up to 256 security profiles.
