Skype for Business Online Ports Reduced

Back in April 2017, I wrote about how Skype for Business Online IP address ranges and ports were planning on being reduced (

The most recent announcement is that this has been completed.

Recent Announcement -

This is a very big change which I know many Skype for Business Online customers will be happy to hear about.  The big change is that UDP/TCP 50,000-59,999 port ranges are now options for Skype for Business Online.  The reason for the change is that given the quality of service that that can be delivered out of Office 365 and the performance Microsoft Network does not require these ports.  Some other facts are:
  • Must be on Skype for Business Online client.
  • UDP/TCP 50,000-59,999 is being marked as optional for Skype for Business Online.
  • If your organization is not blocking them today, still recommended that you keep them open.
  • This change is only for users in Skype for Business Online (in Office 365).  If you have a hybrid environment these ports are still required.
I highly recommend that you review the details of the announcement.

Here is a reference to all Office 365 URLs and IP address ranges -

Office 365 and Azure EMS Overlap

I decided to create a simple cheat sheet for folks to help you understand how Office 365 suites such as E3 and E5 relate to Azure Enterprise Security + Mobile Suite (EMS).  There is a lot of cross-over and relationship between these capabilities.

I will assume in this discussion we are an Office 365 customer trying to understand how does EMS overlap and extend Office 365.

EMS Suites

First, we must first understand what is in the EMS Suites.  There are two EMS Suites E3 and E5.  Here is an overview site -

EMS E3 is made up of:
  • Azure Active Directory Premium P1 - Designed to empower organizations with more demanding identity and access management needs, Azure Active Directory Premium edition provides feature-rich enterprise-level identity management capabilities and enables hybrid users to seamlessly access on-premises and cloud capabilities. This edition includes solutions for the information worker and identity administrators in hybrid environments across application access, self-service identity and access management (IAM), and security in the cloud.  Solutions available are: Secure single sign-on to cloud and on-premises apps, Multi-factor authentication, Conditional access and Advanced security reporting.
  • Azure Information Protection Premium P1 - Control and help secure email, documents, and sensitive data that are shared outside the customer walls with Azure Information Protection Premium (formerly known as Active Directory Rights Management Service (AD RMS)). From easy classification to embedded labels and permissions, enhance data protection at all times with Azure Information Protection—no matter where it’s stored or who it’s shared with.  Solution provides encryption for all files and storage locations and cloud-based file tracking.
  • Microsoft Intune - Microsoft Intune provides mobile device management, mobile application management, and PC management capabilities from the cloud. Using Intune, customer can provide personnel access to corporate applications, data, and resources from virtually anywhere on almost any device, while helping to keep customer information secure.  With the increasing volume and diversity of both ‘bring your own device’ (BYOD) and corporate-owned devices being used in organizations today, a growing challenge for IT departments is keeping corporate information secure. Microsoft mobile application management (MAM) and mobile device management (MDM) solutions help minimize this complexity by offering management capabilities both on-premises and in the cloud, all from a single console.  Solution provides mobile device and app management to protect corporate apps and data on any device.
  • Microsoft Advanced Threat Analytics (ATA) - Microsoft Advanced Threat Analytics (ATA) protect customer from advanced, persistent cyber threats.  From detecting known malicious attacks to uncovering abnormal activity with machine learning and behavioral analytics, identify advanced persistent threats to customer quickly and act swiftly with Microsoft Advanced Threat Analytics.  Solution provides protection from advanced targeted attacks by applying user and entity behavior analytics.
EMS E5 is made up of:
  • Azure Active Directory Premium P2 - Builds off Azure Active Directory Premium P1, enhanced with advanced identity protection and privileged identity management capabilities.  Solution includes risk-based conditional access and privileged identity management.
  • Azure Information Protection Premium P2 - Builds off Azure Information Protection Premium P1 providing intelligent classification policies to classify and label data at time of creation or modification based on source, context, and content. Classification with Azure Information Protection is fully automatic, driven by users or based on recommendation.  Additionally, this services provides Hold Your Own Key (HYOK) that spans Azure RMS and Active Directory RMS for highly regulated scenarios.
  • Microsoft Cloud App Security - Microsoft Cloud App Security provides enterprise-grade security for customer cloud applications.  Whether or not you're in the cloud, customer personnel are. Bring the security of on-premises systems to cloud applications—both approved and unapproved—for deeper visibility, comprehensive controls, and enhanced protection against cloud security issues.  Solution provides enterprise-grade visibility, control, and protection for cloud applications.
How does this compare with Office 365 solutions?
There is overlap with Office 365 solutions.  There are tons of good reference articles that show you exactly where deltas are.

Azure AD Overlap
As you know when you have an Office 365 instance, Azure AD is used underneath the hood.

Azure AD Comparison Table -  This table shows you the difference Office 365 and the features and capabilities you get with Azure AD Premium Plans 1 and 2.

Azure Information Protection / Rights Management Overlap
If you are an Office 365 E3 customer, you may know you get some Office 365 Rights Management.  However Azure Information Protection Plans 1 and 2 provided extended capabilities.

Information Rights Management Comparison Table - - Shows you exactly what you get between the different plans.

Office 365 MDM / Microsoft Intune Overlap
Office 365 natively provides some MDM capabilities.  EMS Intune is the enterprise capability for MDM.  Office 365 MDM is just providing a subset of Intune for Office 365 only.

Microsoft ATA and Office 365 Advanced Security Management Overlap
Office 365 Advanced Security Management (ASM) is part of the Office 365 E5 Suite.  Microsoft ATA is part of the Azure EMS E3 Suite.

Unfortunately, there is not a good comparison table like with the other service offerings previously discussed, yet there are some good references.  Just like previously discussed, Office 365 ASM is providing a subset of Microsoft ATA but Office 365 ASM is a subset of capability for Office 365 only.

Office 365 ASM - – This is a good reference article that describes the types of alerts that you can sign-up for, monitor cloud app usage and set-up SIEM integration for logging.

Azure Threat Analytics (ATA) is a broader approach that extends to on-premises.  Here is the top-level article on it -
