In many companies, identity security has grown into a patchwork. Employees, customers, partners, suppliers, and service providers often each use their own separate access system. Rules lack consistency, access rights follow no clear logic, and the administrative burden becomes enormous. Anyone who thinks this is merely annoying—but otherwise harmless—is mistaken. In reality, such a fragmented identity landscape creates serious security gaps. And many decision-makers still fail to take the next step. For example: are you already protecting your B2B2X environment with a well-designed, consistent identity concept?

Before you read on: we also covered this topic in a webinar together with our partner Descope. So if you would rather listen than read, you can access the webinar recording here: “Managing B2B2X Identities Successfully – Best Practices for Security and User Experience.” (Available in German only)

Let us start at the beginning: there is good news and bad news. The good news first? Many companies have already firmly established Customer Identity and Access Management (CIAM). That means they are aware of the risks that arise when customer, partner, or service-provider identities are managed in an unprotected and unstructured way. If that happens, unauthorized users can gain access easily and open the door to cybercriminals—leading to data loss and compliance violations.

The bad news is that CIAM, when implemented inconsistently and not approached holistically, creates a new set of challenges. Here are five examples:

• Identity silos: Identities of end customers, intermediaries, partners, and corporate customers are spread across a wide variety of systems, each with its own role model and security policy. Transparency and control disappear faster than you can spell “CIAM.”
• Complex onboarding and offboarding: The first problem immediately leads to the next. Onboarding and offboarding have to happen across all systems and all of the user groups mentioned above—still often manually and therefore prone to error, especially when offboarding is missed.
• Delegation: In B2B2X environments and partner management in particular, first-generation CIAM solutions often lack delegated management. Partner companies should be able—and encouraged—to manage access for their own employees within a secure framework. But how is your IT team supposed to know when someone at a partner company has been promoted or left the organization?
• Fragmented security concepts: External identities often get the short end of the stick when it comes to security. They frequently cannot be integrated into internal Identity and Access Management because that environment only manages people coming from the HR system. Customers or partners? No chance.
• High administrative effort: Taken together, all of this creates an almost unmanageable set of drawbacks that place unnecessary administrative pressure on IT teams.

If you would like to explore the topic of successful CIAM in more depth, take a look at our blog post: More Than Just “Who’s Who”: CIAM for B2C, B2B, and B2P Scenarios.

All right, we cheated a little: there is one more piece of bad news. Security does not stop with Identity and Access Management for employees and CIAM for external stakeholders. Modern ecosystems go beyond the familiar B2B world—all the way to the “X.” That “X” is a placeholder representing a wide range of additional actors. Put simply, it can mean the customers, partners, suppliers, and service providers of your customers, partners, suppliers, and service providers.

In other words, identities no longer stop at the company boundary—they extend across multiple organizations.

• Example 1: A manufacturer gives a reseller access to certain systems. The reseller, in turn, allows its end customers and service partners to view data there as well.

• Example 2: A corporation works with an external IT service provider, which then brings in subcontractors. Every party involved needs access—and every missing identity concept creates new gaps.

• Example 3: In supply chains, not only direct suppliers but also their partners or logistics providers gain access to portals.

So what is the lesson here? In a B2B2X environment, many different actors want to take part—but companies need to define clear rules for them within an identity security framework. And now for some balance, because there is good news again: reaching that goal is more straightforward than it may seem. All it takes is the right combination of strategic groundwork and technical support—with a CIAM solution.

Now that you understand the importance of broader CIAM—beyond the familiar B2B environment—the first step is already behind you. The next phase is strategic preparation. Start by answering a few key questions:

• Analyze the identity landscape: Which actors are part of the B2B2X environment? Across how many systems are identities currently distributed?
• Assess the risks: Where do security gaps arise due to manual processes, silos, or missing integration?
• Define governance: Who is responsible for which external identities? Which policies apply to partners, subcontractors, or supply chains?

Understanding the current state is the foundation for improving security. And you do not have to do it alone.

There is broad agreement that companies need to move away from manual processes if they want greater efficiency and security. The same is true in CIAM. Switching to technical support—such as Descope’s modern CIAM platform—brings clear benefits. But what should such a solution actually offer?

• Unified user profile: Every person—whether employee, business customer, supplier, or service provider—must be uniquely identifiable. Permissions and roles need to be tied to this central profile instead of being scattered across parallel accounts.
• Delegated administration: External admins should be able to manage their own users within a secure framework. This speeds up both onboarding and offboarding and significantly reduces the burden on internal IT.
• Flexible authentication: Different user groups expect different journeys—from traditional login to social sign-in to passwordless authentication. A CIAM solution needs to support this flexibility without sacrificing security.
• Cross-company integration: Federated identities such as SAML or OpenID Connect make it possible to connect external systems securely and use single sign-on—without creating duplicate accounts.
• Automated lifecycles: User access must be created, adjusted, or revoked automatically whenever roles change or projects end. This is the only way to consistently avoid orphaned accounts and unclear permissions.
• Transparency and reporting: Security teams need visibility at all times into which identities exist, which permissions are active, and where anomalies occur. Without that, the overview is quickly lost in a B2B2X environment.
• Reduced IT workload: CIAM solutions minimize manual work in help desks and IT teams by automating routine tasks such as password resets, role changes, and access approvals. That leaves more time for strategic work—and users benefit from a smoother experience.
• No-code/low-code integration: Visual workflows and configuration building blocks make it much easier to implement new identity journeys, authentication methods, or interfaces quickly and without deep programming expertise. This accelerates time to market and gives companies greater flexibility. Even business teams can actively contribute to identity processes.

B2B2X once again shows just how often security appears more complicated than it really is. But when decision-makers take a closer look, they often find that stronger protection is not difficult to achieve—and can even bring relief. So our recommendation is simple: look beyond the boundaries of your current CIAM setup and include the “X” as well. Otherwise, a security risk may still find its way to you through several indirect connections.
