F5 BIG-IP Zero Trust Access
Introduction F5 BIG-IP Zero Trust Access, a key component of the F5 Application Delivery and Security Platform (ADSP), helps teams secure apps that are spread across hybrid, multi-cloud and AI environments. In this article, I’ll highlight some of the key features and use cases addressed by BIG-IP Zero Trust Access. F5 BIG-IP Zero Trust Access improves security and the user experience while managing access to your portfolio of corporate applications. Demo Video What is Zero Trust? Key Zero Trust Concepts Zero Trust is a cybersecurity framework built on the following core concepts: Never Trust Similar to human concepts that trust is not given freely, it is earned Always Verify Authenticate and authorize based on all available data points Continuously Monitor Zero Trust is an ongoing security framework that requires monitoring F5 enables zero-trust architectures that optimize your investments and extend zero-trust security across your entire portfolio. Why is this important? Securing apps is complex because apps are spread across a hybrid, multi-cloud environment. Apps themselves have become hybrid in nature, too. This creates 2 problems: Legacy and custom applications can complicate access security. Apps residing anywhere increases the attack surface. F5 BIG-IP Zero Trust Access secures hybrid application access. Securely managing access to corporate applications is critical to preventing data breaches. Doing it well can also increase efficiencies in business processes and user productivity. A Zero Trust security model can deliver this business value by enabling users to seamlessly and securely access their applications from anywhere regardless of where the application resides. In today’s world of hybrid, multicloud and AI applications, Zero Trust is a must. Application access control is key to any Zero Trust architecture. How does F5 address Zero Trust? F5 Zero Trust Begins with Secure Access to All Apps. The F5 Application Delivery and Security Platform (ADSP) is the foundation for Zero Trust Architectures. F5 ADSP delivers visibility, enforcement, and intelligence where it matters most: the application layer. While there are many important components to Zero Trust, we will be focusing on Zero Trust Application Access: Identity-Aware Proxy - Secure access to apps with a fine-grained approach to user authentication and authorization that enables only per-request context- and identity-aware access. Single Sign-On (SSO) and Access Federation - Integrating with existing SSO and identity federation solutions, users can access all their business apps via a single login, regardless of if the app is SAML enabled or not. OAuth 2.0 and OIDC Support - Enable social login to simplify access authorization from trusted third-party identity providers like Google, LinkedIn, Okta, Azure AD, and others. Identity Aware Proxy (IAP) – A Key Component of Zero Trust Use the Guided Configuration to configure the Identity Aware Proxy. From the BIG-IP UI, go to Access > Guided Configuration > Zero Trust. Select the Identity Aware Proxy You will see a configuration example of Identity Aware Proxy Click Next at the bottom For the Config Properties, give it a name, “IAP_DEMO” in this example Set the below options to On Click Save & Next Enable the F5 Client Posture Check Select your CA Trust Certificate Click Add Give it a Name, “FW_Check” in this example Under Windows, select Firewall and Domain Managed Devices Enter your domain name, “f5lab.local” in this example Click Done Click Save & Next Configure the Virtual Server Properties Switch Advanced Settings to On Set the Destination Address, “10.1.10.100” in this example For the Client SSL Profile, select the Client SSL Certificate, Private Key and Trusted Certificate Authorities For the Server SSL Profile, select your Server SSL Certificate and Private Key Click Save & Next Click Add under Authentication Give it a Name, “AD” in this example Set the Authentication Type to “AAA” Set the Authentication Server Type to Active Directory Choose your Authentication Server, “ad-servers” in this example Check the box for Active Directory Query Properties Under Required Attributes, find “memberOf” and click the arrow to move it to Selected Click MFA Click Add Double click Radius Under Choose Radius Server, select Create New Give it a name, “radius_pool” in this example Enter the Server IP Address, “10.1.20.8” in this example Enter the Secret in the two fields Click Save Click Save & Next Click Add Give it a name, “basic_sso” in this example For the SSO Configuration Object, click Create New The Username Source and Password Source should be set like the following Click Save Click Save & Next Under Applications click Add Give it a name, “iap1.acme.com” in this example Under Application Properties, set the FQDN and Caption to “basic.acme.com” Set the Pool IP Address to 10.1.20.7, Port 443, HTTPS Click Save For the Auth Domain, enter “iap1.acme.com” Click Save & Next Set Primary Authentication to “AD” Click Save & Next Click Add under Contextual Access For the Contextual Access Properties, give it a name, “basic.acme.com” in this example Set the Resource to iap1.acme.com Set Device Posture to FW_CHECK Set Single Sign-On to basic_sso Find the Sales Engineering Group and click Add Select the box for Additional Checks Set the Match Action to Step Up Set Step Up Authentication to Custom Radius based Authentication Click Save & Next The Remediation Page must be changed to a real host where users can download and install the EPI updates In this example, it has been changed to “https://iap1.acme.com/epi/downloads” Click Save & Next Click Save & Next Click Deploy Click Finish when the deployment completes Test the functionality by going to a client computer and accessing https://iap1.acme.com Logon with valid credentials You should see a page like the following Click basic.acme.com Login with valid credentials & click Validate You should see the basic.acme.com web page and be already logged in Note: If you disable the Windows Firewall on the client, you should get a block page similar to the following: Conclusion BIG-IP introduces a powerful access experience. BIG-IP provides a variety of Authentication, Federation, SSO and MFA protocols allowing for modern to legacy protocol translation.

Introduction Enterprises often separate environments—such as development and production—to improve efficiency, reduce risk, and maintain compliance. A critical enabler of this separation is network segmentation, which isolates networks into smaller, secured segments—strengthening security, optimizing performance, and supporting regulatory standards. In this article, we explore the integration between Nutanix Flow and F5 Distributed Cloud, showcasing how F5 and Nutanix collaborate to simplify and secure network segmentation across diverse environments—on-premises, remote, and hybrid multicloud. Integration Overview At the heart of this integration is the capability to deploy a F5 Distributed Cloud Customer Edge (CE) inside a Nutanix Flow VPC, establish BGP peering with the Nutanix Flow BGP Gateway, and inject CE-advertised BGP routes into the VPC routing table. This architecture provides full control over application delivery and security within the VPC. It enables selective advertisement of HTTP load balancers (LBs) or VIPs to designated VPCs, ensuring secure and efficient connectivity. By leveraging F5 Distributed Cloud to segment and extend networks to remote location—whether on-premises or in the public cloud—combined with Nutanix Flow for microsegmentation within VPCs, enterprises achieve comprehensive end-to-end security. This approach enforces a consistent security posture while reducing complexity across diverse infrastructures. In our previous article (click here) , we explored application delivery and security. Here, we focus on network segmentation and how this integration simplifies connectivity across environments. Demo Walkthrough The demo consists of two parts: Extending a local network segment from a Nutanix Flow VPC to a remote site using F5 Distributed Cloud. Applying microsegmentation within the network segment using Nutanix Flow Security Next-Gen. San Jose (SJ) serves as our local site, and the demo environment dev3 is a Nutanix Flow VPC with an F5 Distributed Cloud Customer Edge (CE) deployed inside: *Note: The SJ CE is named jy-nutanix-overlay-dev3 in the F5 Distributed Cloud Console and xc-ce-dev3 in the Nutanix Prism Central. On the F5 Distributed Cloud Console, we created a network segment named jy-nutanix-sjc-nyc-segment and we assigned it specifically to the subnet 192.170.84.0/24: eBGP peering is ESTABLISHED between the CE and the Nutanix Flow BGP Gateway in this segment: At the remote site in NYC, a CE named jy-nutanix-nyc is deployed with a local subnet of 192.168.60.0/24: To extend jy-nutanix-sjc-nyc-segment from SJ to NYC, simply assign the segment jy-nutanix-sjc-nyc-segment to the NYC CE local subnet 192.168.60.0/24 in the F5 Distributed Cloud Console: Effortlessly and in no time, the segment jy-nutanix-sjc-nyc-segment is now extended across environments from SJ to NYC: Checking the CE routing table, we can see that the local routes originated from the CEs are being exchanged among them: At the local site SJ, the SJ CE jy-nutanix-overlay-dev3 advertises the remote route originating from the NYC CE jy-nutanix-nyc to the Nutanix Flow BGP Gateway via BGP, and installs the route in the dev3 routing table: SJ VMs can now reach NYC VMs and vice versa, while continuing to use their Nutanix Flow VPC logical router as the default gateway: To enforce granular security within the segment, Nutanix Flow Security Next-Gen provides microsegmentation. Together, F5 Distributed Cloud and Nutanix Flow Security Next-Gen deliver a cohesive solution: F5 Distributed cloud seamlessly extends network segments across environments, while Nutanix Flow Security Next-Gen ensures fine-grained security controls within those segments: Our demo extends a network segment between two data centers, but the same approach can also be applied between on-premises and public cloud environments—delivering flexibility across hybrid multicloud environments. Conclusion F5 Distributed Cloud simplifies network segmentation across hybrid and multi-cloud environments, making it both secure and effortless. By seamlessly extending network segments across any environment, F5 removes the complexity traditionally associated with connecting diverse infrastructures. Combined with Nutanix Flow Security Next-Gen for microsegmentation within each segment, this integration delivers end-to-end protection and consistent policy enforcement. Together, F5 and Nutanix help enterprises reduce operational overhead, maintain compliance, and strengthen security—while enabling agility and scalability across all environments. This integration is coming soon in CY2026. If you’re interested in early access, please contact your F5 representative.

Configuration Assistance: Configure Email Alerts for HA Failover Events and Device Offline
We have a BIG-IP VE High Availability Pair deployed in Microsoft Azure. We need to configure the BIG-IP to automatically send an email notification to our Operations teams immediately when a Failover event occurs(When the unit goes from Active to Standby or Offline) Could you provide the recommended procedure for the configuration to trigger these email alerts?WAFaaS with SSL Orchestrator
Introduction Note: This article applies to SSL Orchestrator versions prior to 11.0. If using version 11.0 refer to the article HERE This use case allows you to insert F5 WAF functionality as a Service in the SSL Orchestrator inspection zone. WAFaaS is the ability to insert ASM profiles into the SSL Orchestrator Service Chain for Inbound Topologies. This configuration is specific to a WAF policy running on the SSL Orchestrator device. WAF and SSL Orchestrator consume significant CPU cycles so care should be given when deploying both together. It is also possible to deploy WAF as a service on a separate BIG-IP device, in which case you’d simply configure an inline transparent proxy service. The ability to insert F5’s WAF into the Service Chain presents a significant customer benefit. This guide assumes you already have WAF/ASM profile(s) configured, licensed and provisioned on BIG-IP and wish to add this functionality to an Inbound Topology. In order to run WAF and SSL Orchestrator on the same device you will need an LTM license with SSL Orchestrator as an add-on option. You cannot add a WAF license to an SSL Orchestrator stand-alone license. SSL Orchestrator does not directly support inserting F5 WAF policies into the Service Chain. However, the F5 platform is flexible enough to handle many custom use cases. In this case, the ICAP service configuration exposes a framework that is useful for any number of specialized patterns, including adding a WAF policy to an SSLO service chain. We will configure an ICAP Service and attach the WAF policy to it. Steps: Create ICAP Service Disable Strictness on the Service Disable TCP monitor for the ICAP Pool ICAP Adapt profiles removed from the Virtual Server Application Security Policy enabled and a Policy assigned under Security Step #1: Create ICAP Service Note: These instructions assume an SSL Orchestrator Topology and Service Chain are already deployed and working properly. These instructions simply add WAFaaS to the existing Service Chain. It is entirely possible to create the WAFaaS during the initial Topology creation, in which case you would create the service during the workflow, then make the necessary changes after the topology has been created. From the SSL Orchestrator Guided Configuration click Services then Add Scroll to the bottom, select Generic ICAP Service and click Add Give it a name, WAFaaS in this example For ICAP Devices click Add on the right Enter an IP Address, 198.19.97.1 in this example and click Done. Note: the IP address you use does not have to be the one above. It’s just a local, non-routable address used as a placeholder in the service definition. This IP address will not be used. IP addresses 198.19.97.0 to 198.19.97.255 are owned by network benchmark tests and located in private networks. Scroll to the bottom and click Save & Next. The next screen is the Services Chain List. Click the name of the Service Chain you wish to add WAF functionality to, ssloSC_ServiceChain in this example. Note: The order of the Services in the Selected column is the order in which SSL Orchestrator will pass decrypted data to the device. This can be an important consideration if you want some devices to see, or not see, the actions taken by the WAF Service. Select the WAFaaS Service and click the right arrow to move it to Selected. Click Save. Click Save & Next Click Deploy You should receive a Success message Step #2: Disable Strictness on the Service From the SSL Orchestrator Configuration screen select Services. Click the padlock to Unprotect Configuration. Note: Disabling Strictness on the ICAP Service is needed to modify it and attach the WAFaaS policy. Strictness must remain disabled on this service and disabling strictness on the service has no effect on any other part of the SSL Orchestrator configuration. Click OK to Unprotect the Configuration Step #3: Disable tcp monitor for the ICAP Pool From Local Traffic select Pools > Pool List Select the WAFaaS Pool Under Active Health Monitors select tcp and click >> to move it to Available. This removes the Pool’s Monitor because otherwise it would be marked as down or unavailable. Click Update Note: The Health Monitor needs to be removed because there is no actual ICAP service to monitor. Step #4: ICAP Adapt profiles removed from the Virtual Server From Local Traffic select Virtual Servers > Virtual Server List Locate the WAFaaS ICAP service that ends in “-t-4” virtual server and select it Set the Request Adapt Profile and Response Adapt Profile to None to disable the default ICAP Profiles Click Update Step #5: Application Security Policy enabled and a Policy assigned under Security For the WAFaaS-t-4 Virtual Server click the Security tab Set Application Security Policy to Enabled Select the Security Policy you wish to use. Click Update when done Note: In specific versions of SSL Orchestrator there is one extra configuration item that needs to be modified. This is NOT required in other versions. If this change is made, when performing an upgrade it is not necessarily required to back out this change. Required versions: SSLO version 5.9.15 available on TMOS 14.1.4 SSLO versions 6.0-6.5 available on TMOX 15.0.x Navigate to “Local Traffic ›› Profiles : Other : Service” Select the Service profile named “ssloS_WAFaaS-service” Change the “Type” from “ICAP” to “F5 Module” Conclusion The configuration is now complete. Using the WAFaaS this way is functionally the same as using it by itself. There are no known limitations to this configuration.
