I’m often asked why Citrix? The answer can be a simple vs. complex one, therefore I choose to demonstrate why Citrix through proactive evangelism by recording myself using my Citrix Workspace actively through-out the year, which initially began in 2016 and lead to the original How vs. where I worked from in 2017 video available at – https://twitter.com/lyndonjonmartin/status/949316537021812736.

Introduction to “Session Watermark”
The latest release of the XenApp & XenDesktop Service powered by Citrix Cloud or if you are performing a private cloud (on-premises) upgrade or net new installation of XenApp & XenDesktop 7.17 has some NEW features (another post brewing) and one that I have been waiting on for quiet sometime now has not finally arrived (WAHOO!) and its VERY VERY simple to configure and aids in improving your security posture (I believe) for delivery of apps & desktops powered by Citrix against e.g IP theft. In the below tweet can you see it?
— Lyndon-Jon Martin (@lyndonjonmartin) April 3, 2018
The above is from my initial tests using a Windows Server 2016 VM hosted in Azure Northern Europe region running the 7.17 VDA configured to my Citrite #CitrixCloud XenApp & XenDesktop Service so I did not need to upgrade anything to get this new SHINY cool feature yes I said it SHINY. All I was required to do was deploy a new Windows Server 2016 VM from the Azure marketplace, domain join it, install the VDA and connect it to my Cloud Connector and I was ready in less than 25 minutes from initially deploying the VM from the marketplace.
Finally on a personal note for me Citrix SysAdmins enabling the “Session Watermark” feature obviously initally tested in a safe environment e.g UAT with a few users from a couple of departments and then rolling it out into production (as when/how your ready) will be making IT the modern “App & Desktop Security Heroes“. IT can apply and configure these new policies to be the most right vs. relevant for your organisations security needs while not hindering the end-users Rich HD eXperience.
Before we get started it is worth mentioning that this feature does add an overhead to the compute on the backend (VDA side) and therefore it is suggested to enable up to two water marking features or items. In my overview of this feature I will wont cover off the cost of implementing this security policy as there are multiple variables to consider e.g HDX Graphics Mode and associated policies to provide the right vs. relevant end-user experience vs. how many watermark items do I apply? I have begun testing so bare with me and I’ll publish my findings either on my personal blog here or on https://www.mycugc.org under the “Expert Insights” area.
“Enable session watermark”
By default this feature is DISABLED as the default behaviour which I believe is the right approach considering its Citrix’s initial release of this #security feature (in my personal view) and secondly online documentation at eDocs suggested recommendations it to enable NOT more than two watermark text items. Finally * indicates that this policy is DISABLED by default when Session Watermark is enabled.
Include client IP address
* This is the IP addr of the device connecting to the virtual app & desktop.
Include connection time
* Utilises the following format yyyy/mm/dd hh:mm to display the users initial connection time to there virtual app or desktop.
Include logon user name
ENABLED by default when you enable Session Watermark as a policy and uses the following format USERNAME@DOMAINNAME is most optimise for 20 characters or less otherwise truncation might occur of the users logon username.
Include VDA host name
ENABLED by default when you enable Session Watermark as a policy and provides the VDA hostname e.g ne1vad01
Include VDA IP address
* Provides the internal IP addr that corresponding the VDA’s hostname e.g ne1vad01 = 10.1.0.7
Session watermark style
ENABLED by default using “Multiple e.g displays five watermark labels” when you enable Session Watermark as a policy or you can configure “Single e.g displays a single watermark label in the centre of the session“. TIP switching to SINGLE and sticking to two watermark text items for me in my initial tests is a good starting policy however time will tell as I continue to test out this new feature and its capabilities with different HDX Graphics Modes and associated tweaks.
Watermark custom text
* A unicode maximum of 25 characters is supported if you exceed this limit it will be truncated.
Watermark transparency
ENABLED by default set to “17 out of 100” when you enable Session Watermark as a policy, personally I think setting it to just 1 is fine in my initial tests as you want it to be not so in your face to the end-users to be bluntly honest.

What is the difference between LTSR vs. CR for XenApp & XenDesktop 7.x?
The Long Term Service Release (LTSR) program for XenApp and XenDesktop provides stability and long-term support for XenApp/XenDesktop releases while the Current Release (CR) provides customers with the very latest version of XenApp and XenDesktop which includes the latest innovations e.g EDT v2
XenApp & XenDesktop 7.15 LTSR Feature Summary Comparison with 7.6 LTSR
The following is a simple one PDF page document that lists all the feature capabilities from initial first LTSR which was XenApp & XenDesktop 7.6 Feature Pack (FP) 1-3 through to the current LTSR XAD 7.15 including the CR releases in-between so its absolutely worth booking marking in your browser or better yet download it to keep it to hand for customer conversations – https://www.citrix.com/content/dam/citrix/en_us/documents/data-sheet/xenapp-xendesktop-715-ltsr-feature-summary-comparison-to-76-ltsr.pdf.
Noteworthy Points What’s New vs. Excluded
I’d very strongly recommend that your read the following CTX article – https://support.citrix.com/article/CTX205549 entitled “CTX205549 FAQ: XenApp, XenDesktop, and XenServer Servicing Options (LTSR)” and to ensure that you remain compliant post your update/migration to 7.15 LSTR you should download the “CTX209577 Citrix LTSR Assistant” https://support.citrix.com/article/CTX209577
Finally while your planning your migration to XA 7.15 (FMA) from 6.5 (IMA) you will mostly likely be upgrading vs. migrating away from WIF so please be sure to read and how to migrate features to StoreFront from your WIF environment at – https://docs.citrix.com/en-us/storefront/3-12/migrate-wi-to-storefront.html. Equally I’d encourage any organisation reading this to review how-to setup and configure the “unified user experience” for Citrix Receiver vs. the Green Bubbles which will provide a much better experience for users you can enable it by quiet easily once you’ve read through the following article in eDocs at – https://docs.citrix.com/en-us/storefront/3-12/manage-citrix-receiver-for-web-site/unified-receiver-experience.html.
– Follow the supported leading best practises for upgrading the 7.15 LTSR by reviewing the following node within Citrix’s eDocs – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/upgrade-migrate/upgrade.html
– VDA installation failures for Win 10 N Editions that don’t include Microsoft Media Foundation can now be acknowledged via the installation GUI of the VDA vs. automated deployed (unattended) there is a new option “/no_mediafoundation_ack“.

What is it?
It is a replacement for the deprecated Microsoft Azure RemoteApp (ARA) – https://blogs.technet.microsoft.com/enterprisemobility/2016/08/12/application-remoting-and-the-cloud/ (“…Support existing Azure RemoteApp customers on the service through August 31st, 2017..“) which provides simplicitic beauty of Microsoft Azure RemoteApp now with the “Secure by Design” enterprise security methodology, platform scalability with FMA in 7.x and HDX virtual app delivery protocol capabilities & power of Citrix XenApp.
ARA brought Remote Desktop Services (RDS) capabiltiies from a multi private cloud deployments on Windows Server to Azure with non-persistent RDS/RDP sessions delivered from the Microsoft Azure Cloud only! The XA Essentials Service is only available from Microsoft Azure Marketplace hosted on Azure and only supports the delivery of Windows apps delivery from Windows Server 2012 R2, 2016 prepared Templates or Bring Your Own Templates (BYOT) uploaded. Citrix has prepared a full FAQ available at – https://www.citrix.com/global-partners/microsoft/resources/xenapp-essentials-faq.html
Overviews & Demonstrations
Introducing XenApp Essentials Service is a demonstration of the Service by Citrix.
Extend the Microsoft RDS platform in Azure through Citrix solutions was a presentation at Microsoft Ignite 2016.
High Level Getting Started, System Requirements & Pre-requistes
1. You’ll need an Azure subscription with a resource group defined with a virtual network.
2. Define your preferred Azure region which you can ref from – https://azure.microsoft.com/en-gb/regions/.
3. Decide on your AD stratergy which can be Active Directory sat in the Azure resource location using a min A3 Standard VM instance for AD or you can utilise “Azure Active Directory Domain Services” and eDocs suggested that you review – https://docs.microsoft.com/en-us/azure/active-directory-domain-services/#main prior to implementing AAD for the XA Essentials Services vs. traditional AD.
4. Define your preferred OS strategy for the service which currently supports server OSes for Windows Server 2012 R2 or 2016 and you’ll need to define master image stratergy e.g BYO image or a Citrix prepared image for the service! Notes: “(a)BYO with your own Server OS template including apps + licenses for those apps or choose Citrix prepared templates with Apps. (b)RDS CALS w/SA to Azure or purchase RDS SALs.”
5. Customer owned Azure Subscription as is responsible for per monthly IaaS consumption costs e.g compute, network, bandwidth & storage
6. Only MCS based provisioning is support for public (Iaas) clouds and for this Service hosted by Microsoft Azure.
7. Subscribe to XenApp Essentials Service through Azure Marketplace at – https://azuremarketplace.microsoft.com/en-us/marketplace/apps/Citrix.XenAppEssentials?tab=Overview.
8. Connect your Azure subscription to Control Plane operated by Citrix Cloud. Citrix Cloud controls customer Azure subscription via Citrix Cloud Connectors to provide capabilities to manage, provision and monitor your XenApp servers which will deliver your HDX virtual apps
1. Before you begin you will requires a subscription to XenApp Essentials Service from
2. Azure Marketplace + Server Images + RDS CALS w/SA
3. Create app collection similar to ARA
4. Create a name
5. Domain Joined (Popular) or Non-Domain Joined (TBC)
6. Link Azure subscription to XAE and select Resource Group, Virtual Networks & Subnet
7. Enter in Domain details which include Domain name, OU, Srv acct + passed
8. Select template image Citrix provided or your OWN
9. Select capacity and mange costs by selecting instance type and power settings scheme (saver logoff after 10min; standard after 1hr; performance after 4hrs or always on i.e do not perform any power mgmt
10. Enter in # of users concurrent and you’ll receive an estimate cost calculator prior to provisioning to understand the costs based on 40hr usage per month
Summary and the deploy
11. Time access is short as CC will provision your instances in your subscription
12. Select app collection click Apps tab then select apps to publish
13. Select users tab and search domain by user or group
14. Return to Manage home and you’ll see that your app collection is now ready with a green tick
15. Select app collection and you’ll see the StoreFront URL to send to users
16. Users login with domain\user + passed
17. Users are now able to launch there HDX virtual apps secured by there organisations Cloud-hosted StoreFront FQDN which provides secure remote access via the NetScaler Gateway Service also review caveats re bandwidth through-puts below.
1. Live.com accounts cannot be used for authenticaiton
2. Users cannot launch and app if an existing RDS session is present on the XA VDA worker.
3. Machine catalogue failures may occur if deploying a VM instance size in a region that does not support that instance type any more.
4. A premium storage account is not supported see “Prepare Your Azure Subscription”
5. Each end-user is limited to 1-GB outbound data transfer per month but you can increase the limit via by acquiring a 25 GB add-on via the Azure Marketplace see “StoreFront and NetScaler Gateway in XenApp Essentials Service”
6. See eDocs for more…

Overview
Today I received my new Mac, yes I’ve decided to move from a PC to a Mac for various reasons (those whom know me are probably going really!?) but I still have a Windows 10 tablet PC which I use regually at home, but most importantly my Windows 10 Citrix issued virtual desktop powered by XenDesktop (Citrix on Citrix) follows me anywhere with Citrix Receiver or the HTML5 Citrix Receiver!
I didn’t even turn on my old PC I just started working within less than 15 min from my new MacBook connected to my Win10 VD via Receiver and i’ll just sort out what I need locally like Reflector, NAMP e.t.c over the weekend as its a busy week post our local partner event Citrix Partner Accelerator.
What Did I Do?
1. Unboxed my new Macbook
2. Plugged in the power and pushed the power button its been a while since I’ve heard that CHIME 🙂
3. Completed Apples on-boarding process including setting up iCloud including connecting to the Citrix employee Wi-Fi from our London, Paddington offices check it out at – https://twitter.com/CitrixUK/status/834742107055259650
4. Next I opened Safari and navigated to http://receiver.citrix.com and it auto detected for me that I am connecting from a Mac and presented me with a download link to Receiver for Mac 12.4.
5. Once downloaded I installed it simple!
6. Opened Citrix Receiver and i entered in my addr which then prompted me for my Citrix employee username, passwd and 2FA Token
7. BOOM Receiver synced all my virtual apps & desktops that I had previously selected on other device(s) within a few moments of signing in
8. I clicked on my Windows 10 Virtual Desktop powered by XenDesktop and my new mobile #SecureWorkspace is ready to go within less than 15 minutes!

1. HDX Adaptive Transport is disabled by default in XAD 7.13* also referred to as EDT is a new HDX graphics mode that utilises both the UDP and TCP protocols with a fallback to TCP where UDP isn’t available. The HDX engineering team have engineered this new Citrix protocol called Enlightened Data Transport (EDT) which utilises the existing Citrix ports 1494 (ICA/HDX) and 2598 (Session Reliability) for both TCP and now new UDP so f/w ACL changes are near enough straight forward. To test this new graphics mode internally:
– Configure the ACL between your test end-point and through your internal network (over a VPN) VM running the 7.13 VDA to allow UDP and TCP for 1494, 2598
– Your test VM instance could be running in Azure (connected on-prem via a VPN) or on XenServer 7.1 and remember must be running the latest desktop or server VDA
– Your test end-point must be running the following min Citrix Receiver versions for Windows 4.7, Mac 12.4 and for iOS 7.2
– *In Studio create a machine catalogue, delivery group or use an existing one with your VDA upgraded from e.g 7.12 to 7.13 and then create a new HDX policy e.g HDX-TestofEDT and select the following HDX policy entitled “” and choose “Preferred“.

Introduction & Overview
The NetScaler Gateway Service is a simple, clean. effortless and but most importantly a powerful way to demonstrate the power of Citrix Cloud by providing secure remote access to your HDX virtual apps and desktops from your resources location over the internet (https) securely. While this service is very very powerful & simple to implement and use, you should under the keep in-mind that NS VPX/MPX/SDX is fully featured vs. the NSG Service which is focused on delivery of HDX virtual apps & desktops! So in summary when implementing service undering what is right vs. relevant for the customer needs and requirements is very important. Finally you can read more about the service and its benefits at https://www.citrix.com/products/citrix-cloud/services.html.
+Enabling the NetScaler Gateway Service
1. Login to https://citrix.cloud.com
2. Select to Manage your XAD Service which will take you to https://xenapp.cloud.com/.
3. Select from the drop down menu “Service Delivery” which is beneath the top menu item displayed “Service Creation”
4. Now Select to toggle “ON” and choose to use the NSG service (preferred for blog article only) or your own NetScaler (Unified) Gateway at your resource location and if you enable to the NSG Service you can choose to check the session reliability (2598) checkbox.
The UX
Users connect to https://.xendesktop.net and then login using there AD UPN domain credentials e.g lyndon-jon@x1co.eu and the user’s credentials are encrypted through-out the login process. User’s can equally choose between using a full Citrix Receiver (HDX Optimisation Pack 2.x.n for offloading Skype for Business 2015-2016) vs. HTML5 Receiver (HTML5 compliant internet browser) experience by selecting their username in the top right hand corner and selecting to “Change Receiver” to their preferred choice of Receiver. It also important to set the correct +HDX Policy to get the best UX that is good and balanced (backend vs. network vs. client connected device) so I’d suggest that you implement HDX Adaptive Display v2 by selecting the following policy entitled “Use video codec for compression” and select the following option “For actively changing regions” and thereafter tweak the frame rate and adjust the Thinwire color depth support as described at http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-12/whats-new.html#par_anchortitle_59c9 and you can also read more about benefits and a YouTUBE demostration on HDX Adaptive Display v2 at the following blog article I wrote in 2016 at – http://axendatacentre.com/blog/2016/10/01/foractivelychangingregions/.
1. User MUST login into cloud hosted StoreFront e.g https://.xendesktop.net. There credentials are securely handled please refer to – http://docs.citrix.com/en-us/citrix-cloud/xenapp-and-xendesktop-service/technical-security-overview.html to understand the traffic follow.
2. Once the user has authenticated successfully he/she can select to launch a virtual app or desktop.
3. User connects to the NSG Service powered by Citrix Cloud
4. Traffic is securely brokered to the Connector in your resource location that is severing up the user’s selected virtual app or desktop or both from the server or desktop VDA.
Tech Overview of the NSG Service
1. The Citrix Cloud NetScaler Cloud Gateway service on your Connector allows and provides the secure remote access feature of the NSG Service from your chosen resource location. I have written a blog article about the Connector services and leading best practises which you can read at – http://axendatacentre.com/blog/2017/01/27/understanding-the-citrix-cloud-its-services-architecture-connectors/.
2. To ensure high availability you should always deploy at a min a pair of Connectors within your resource location and increase the compute capacity of your Connectors as user demand increases initially and thereafter deploy another Connector based upon usage of service.
3. *To use the NSG Service you MUST configure to use the cloud-hosted StoreFront provided by Citrix Cloud under “Service Delivery” tab at https://xenapp.cloud.com/delivery.
4. The NSG Service only supports HDX Traffic only and the service is currently only available on Eastern, Western coasts within the USA and in Europe so for those users accessing virtual apps and desktops via the NSG Service outside of these geos or not in close proximity to an entry point will experience higher latency so tweak your HDX policy(s)+ accordingly or deploy a NS VPX in your resource location.
5. ICA files are STA signed the below example is a small snippet from my own PoC and testing*. I have also intentionally scrammed some of the unreliable text to :-).
The NSG Service currently does not support and or is limited as of writing this blog article in Jan 2017 and based upon the embedded Twitter image – http://docs.citrix.com/en-us/citrix-cloud/xenapp-and-xendesktop-service/netscaler-gateway-as-a-service.html. Finally please remember that Citrix Cloud is consistently been updated and upgraded with new feature so please please refer to the online documentation and the service overview of Citrix Cloud even a day after posting the blog article as it may become out of date! You’ve been warned!
6. No support for Unified experiences (e.g Branding with your logo, colour scheme).
7. No support for Two Factor Authentication.
8. No support for authentication via outbound proxies for access outside of the resource location over the internet.
