Endpoint Security in 2026: Why Identity Alone Is No Longer Enough

Monday morning, 8:42 a.m. An employee logs into the CRM. The username is correct, the password is correct, and multi-factor authentication is confirmed. Yet this was almost the moment when sensitive customer data would have been leaked without anyone noticing.

The reason? The identity was verified beyond a doubt, but the condition of the device was not checked. 

Why identity-based security is reaching its limits

For many years, companies have built their security architecture around identity. Strong passwords, multi-factor authentication, and identity and access management were considered the standard for security. 

This approach is based on the assumption that a verified identity automatically ensures secure access.

In a work environment characterized by remote work, cloud systems, and bring-your-own-device policies, this equation no longer holds true. A user can log in correctly and verify their identity unambiguously, yet still access company data via an insecure or compromised device.

Identity determines who has access. However, it says nothing about how secure that access actually is.

The Underestimated Threat: Vulnerable Endpoints

Today, endpoints are the primary target for attacks. A laptop without the latest security updates, an infected plugin, or an unprotected private network are all it takes to create a point of entry.

That was exactly what happened in the scenario described at the beginning. The device in question was not up to date, and an unnoticed vulnerability had already taken hold. While the employee was working as usual, a process was running in the background that was able to intercept data.

In the case described, theattack originatedfrom a personal laptop used for remote work. What nobody knew was that the device hadn’t been updated in weeks. A seemingly harmless browser extension had become a gateway for the attack.

When the employee accessed sensitive data, she did not do so on her own. The attacker did not have to steal login credentials or bypass security measures. He simply took advantage of the fact that the system was already authenticated.

This is where the real vulnerability lies: it wasn't the identity that was compromised, but the context. This is the real vulnerability of IT infrastructures, one that is often overlooked:

• Is the device up to date?
• Is there an active threat running in the background?
• Does it comply with the company's security policies?

Without these answers, any identity verification remains incomplete.

Context as a New Dimension of Security

The term "context" refers to all factors that go beyond mere identity. These include the device's status, location, network, and user behavior during access.

In modern IT environments, it is precisely this context that determines whether access is secure or not. A device that is unpatched or operates outside defined security policies poses a risk regardless of who is using it.

Companies that fail to take this context into account are operating with an incomplete security model. They rely on identity without verifying the actual circumstances.

We can no longer define the perimeter based on network boundaries or IAM policies alone, but only through the dynamic context of each individual transaction.

Anyone who ignores the health status of the endpoint during access control today is leaving the biggest gateway for attackers wide open. Continuous Context Evaluation is now the absolute baseline for any secure cloud architecture.

What we specifically recommend at StackWorks

In practice, the goal isn't to introduce yet another tool. What matters is a consistent approach that logically links identity, device, and access.

Based on our experience with medium-sized and regulated companies, we recommend three specific steps:

1. Make device status a prerequisite for all access

Access to sensitive data should always be contingent on the security status of the device. This means that a device without the latest security updates or with an unknown status will not be granted unrestricted access.

2. Consistently implement risk-based access control

Risk-based access to the environment should not be optional, but rather a central control layer.

It makes sense to classify access in a smart way:

• Full access on secure, managed devices
• Restricted access in case of uncertainty
• Blockage with an increased risk

This results in a system that remains flexible and is clearly controlled.

3. Establish endpoint security as a governance priority

In many companies, the crucial realization only comes after an incident has already occurred. Endpoint security must not be treated as an isolated IT issue. Regulatory requirements such as the GDPR and, for Switzerland, the nDSG make it clear that it is no longer sufficient to simply store or encrypt data. Companies must be able to demonstrate that access to this data occurs under secure conditions. Without transparency regarding device status, this very proof remains incomplete. 

The issue is also increasingly shifting toward the areas of liability and governance. Security vulnerabilities are no longer just technical weaknesses, but also a legal risk. Of course, this also affects business continuity. 

Endpoint security should not remain an isolated IT issue. It belongs in:

• Risk Management
• Compliance Strategies (GDPR, NIS2)
• Business Continuity Planning

Only when this perspective is firmly embedded in management will security be effective in the long term.

Our conclusion: Trust requires verification

The idea that a valid login is synonymous with security is a thing of the past. In a connected, mobile work environment, identity alone is no longer enough.

Modern cybersecurity is based on three pillars: identity, context, and device status. Only when all three factors are taken into account can true security be achieved. Technical verification of device status will make companies truly resilient by 2026.
