If you haven’t heard already, F5 closed out the year of 2020 by announcing a new and completed free of charge service called F5 Device ID+. The free service is available for all F5 customers with up to 20 million devices. This number of 20 million, refers to the number of unique customer devices that visit your Websites, Applications, and Web based Services.
The concept of a Device ID isn’t exactly a new thing, but the way it’s delivered by F5, and the fact that it’s offered at no cost, does make it a unique and revolutionary offering.
We have already published a board range of information relating to the service, including a Video Introduction, and Introductory page on F5.com, as well as the getting Started documentation on F5 Cloud Docs.
There are multiple ways to configure and consume the new F5 Device ID+ service, and the one we wanted to talk about today, was how and why to combine this new capability through the F5 Silverline Security-as-a-Service solution.
F5 Device ID+ is a real-time, high-precision device identifier that utilizes advanced signal collection and proven machine learning algorithms to assign a unique identifier to each device visiting your site. Deployment is simple, with immediate benefits for the security, networking, fraud, and digital teams. Never has understanding the unique devices visiting your applications been so easy.
Further information on the Use Cases for F5 Device ID+ can be found on the Product overview Datasheet

F5 is the industry leader in Application Delivery and Application Security Services. F5 Silverline is the simplest and most cost effect way to deploy and operated a globally dispersed Application Services solution, and F5 Shape provides the most innovative and comprehensive range of anti-bot and anti-fraud solutions, with a laser focus on effectively identifying devices and their intentions.
F5 Silverline provides a zero-effort way to activate and consume the F5 Device ID+ service, powered by the machine learning analysis of Device, Browser, network and environmental signals and telemetry discovered by the F5 Shape Cloud AI engine. Bringing these two great services together is a bit of a no brainer, and existing F5 Silverline customers, can simply flip a Toggle switch to get the HTTPS enabled applications provisioned to start processing traffic in real time, and assigning a unique identifier to every device interacting with your websites and Apps.
If you're new to F5 and want to take advantage of this unique combination of Fully Managed Services, you can request a free trial of the F5 Silverline WAF or F5 Silverline Shape Defense at F5.com.
Device ID+ can only be configured on HTTPS services for Applications provisioned as an Application Proxy within the Silverline system.
Application proxies are the recommended way to deploy HTTP & HTTPS Services to your protected Web Applications and allow you to take advantage of the Silverline Regional POPs and newer services such as Multi-FQDN configuration and Silverline Shape Defense.
More information on the configuration and Application Proxies can be found on the support knowledge base HERE
Navigate to the Application Proxy you wish to enable for Device ID+ and follow these steps to activate the configuration:
1. Navigate to the HTTPS Service on the Application Proxy
2. Navigate to the Shape Security Tab
3. Switch the DeviceID+ Toggle to the ON position
i. Must be unique and cannot already be in use in your Application
ii. Do Not Use a name that indicated Shape or Silverline in the path
i. Before <script>
ii. After <head> (our preferred option)
iii. After <title>
iv. Other – Customer-configured
If you are not able to locate the Shape Security Tab, or the Device ID+ Toggle switch, please contact the Silverline SOC for assistance.
In order for you to then be able to leverage the F5 Device ID+ identifiers, there will be some work that you need to do in your Application logic.
Full details on how to work with this solution can be found on the F5 Cloud Docs website HERE
You will find the details of the two unique identifiers the solution creates. residue-based identifier and an attribute-based identifier. The residue-based identifier is based on local storage and cookies. The attribute-based identifier is based on signals collected on the device. The two identifiers always have different values.
The residue-based identifier will change whenever local storage is deleted, such as when a user clears cookies. We expect this identifier will have lower persistence and hence high divisions, that is, the same device might appear to have different residue-based identifiers over time. On the other hand, because the residue-based identifier is a sufficiently long random string, there is nearly no chance of collision (that is, when one identifier is shared by more than one device).
The attribute-based identifier, based on signals collected from the device, is more persistent in that it will remain the same even when the user clears local storage. However, the attribute-based identifier could change when certain events occur such as a browser update, configuration change, or hardware change. Device ID+ continuously strives to base the identifier on the most persistent of signals, those least likely to change.
The attribute-based identifier, however, does not guarantee persistence. It is possible for two devices to share an attribute-based identifier if the devices are sufficiently similar. Again, F5 performs continuous research to collect signals that will minimize collisions.
Your initial thoughts may well be that the solution seems limited in its current form, and that we are asking your development teams to do the heavy lifting, to actually start to leverage the Device identifiers.
In some ways this is true, however it’s likely that you are already using some kind of session tracking or device identifier, such as cookies. All we are providing is a more reliable and tamper proof alternative identifier, as part of this free service.
This service will enhance your visibility and awareness of the users and devices traversing your websites and application, but the story doesn’t end there.
F5 does offer several additional Security solutions that leverage this fundamental Device ID+ to provide advanced Bot Detection, and other anti-fraud capabilities.
The F5 Device ID+ service should be seen as a foundational element to your overall security posture.
As such, in the very near future, we will be enhancing the F5 Silverline Customer Portal with some additional Dashboard charts built on the Device ID+ Analytics.
In the next phase of development, we will be adding additional visibility and analytics gathered from DeviceID+ into the Silverline Dashboards, charts and Statistics.
