Zero trust security for the digital workplace

Discover why a zero trust approach to security is essential for protecting today’s digital workplace.

Connect and support people

Today, almost every workplace is digital. From healthcare to finance to manufacturing, technology is transforming productivity in ways that were unimaginable just a few years ago.

But this shift also creates more opportunities for cybercriminals to access and exploit sensitive data.

As organizations rapidly adopt new tech and pivot to new ways of working, they also expand the number of entry points for attackers.

Relying on traditional security measures is no longer enough because they simply weren’t designed for the modern workplace. To reduce risk, businesses must adapt their security protocols to meet today’s challenges.

One of the most effective ways to improve security is to adopt a zero trust approach. This strategy involves verifying every user and device, regardless of whether they are inside or outside the network.

The problem with traditional network security  

For many years, and even still today, IT network security operated on the principle that anything inside the network could be trusted implicitly.

Often referred to as a “castle and moat”, this approach focuses on protecting the castle (the network) with a moat (firewalls, VPNs, authentication, etc.).

But in today’s world, where people, devices, and data live outside company walls, this model no longer works.

The zero trust alternative  

Zero trust flips the old approach on its head. It assumes that a breach will happen and that no user or device can be trusted, even if it’s inside the network.

Ahmed Elattar, Senior Technical Product Marketing Manager at TeamViewer, explains zero trust like this: “Trust must be earned. Only when it’s known for certain that a device or person is authorized is access granted.”

In practice, earning trust means that users automatically start from a position of least privilege, and their access is strictly limited to the resources they need to do their job.

This minimizes network exposure so that if a breach does occur, the attacker only has access to a limited amount of data.

Access isn’t just restricted; it’s also continually monitored and validated. Both users and devices must pass continuous, contextual authentication and validation to maintain access. This includes checks on location, the device being used, the time of access, and user behavior patterns.

In short, zero trust means always verifying and never giving access blindly. It helps organizations limit risk and stay secure as threats continue to evolve.

Why is zero trust important in the modern digital workplace?  

More endpoints mean more risk

As organizations grow, so does the number of devices and services they use. The more endpoints they have, the greater the number of possible attack vectors for cyber criminals.

“Each new laptop, phone, server, and app adds another potential door into the business,” says Elattar.

This growing attack surface, combined with increasingly sophisticated, AI-powered attacks, significantly raises the chances of a cyber breach. According to Check Point, global cyberattacks have risen by 44% in 2025 alone.

With attacks now more common, minimizing their impact is critical. Zero trust helps limit damage by enforcing strict access controls and network segmentation.

And with continuous verification, there’s a much higher likelihood that suspicious activity will be detected quickly, allowing teams to respond before more damage is done.

Borderless networks

Today, more people, devices, data, and apps operate outside the traditional corporate network. The old castle-and-moat approach can’t protect what it no longer sees.

Employees now log in from public WiFi, often on personal devices that the IT team doesn’t manage. As Elattar puts it, “You don’t know what apps people have on their personal devices, or if there’s malware running in the background.”

And attackers are taking advantage. In 2024, over 70% of infected devices were personal, as threat actors targeted bring-your-own-device (BYOD) environments to breach corporate networks.

Zero trust ensures that only verified users on approved devices can access company systems.

Threats from inside

A traditional network security approach assumes that employees, or anyone else with network access, always act in good faith.

But recent research tells us that this is a dangerous assumption.

According to IBM, 83% of organizations reported insider attacks in 2024. Five times the amount recorded in 2023.

Zero trust removes blind trust by holding everyone inside the network to the highest level of scrutiny.

TeamViewer Tensor: Zero trust remote access  

In modern enterprises, remote connections are constantly happening across offices, devices, and time zones. To keep these connections safe, you need remote access software with zero trust built in from the start.

TeamViewer Tensor’s zero trust capabilities can be likened to a secure corporate building where access is tightly controlled throughout.

How Tensor puts zero trust into action  

Guarded entry

To ensure only verified users gain access, TeamViewer Tensor integrates with single sign-on (SSO) providers, using SAML 2.0 and SCIM protocols.

This means that employees can log in securely using the same credentials they already use for other corporate tools.

As Elattar explains, “Allowing users to log in with their existing corporate ID and password means one less set of credentials and a smaller attack surface for hackers to exploit.”

Tensor SSO also benefits IT teams by giving them the ability to manage policies from one place, roll out updates across the company, and quickly remove access when employees leave.

Strict access controls

Once someone is logged in, Tensor’s Conditional Access takes over. It decides exactly who can access what, when, and from where.

Tensor’s Conditional Access is not only secure by design, it’s secure by default. Meaning all connections are blocked until approved. “When you first set up Conditional Access, it blocks everything,” says Elattar. “Then you grant access based on your own rules.”

Those rules can be as specific as device type, user identity, geographic location, or session length.

Conditional Access can also be set up for contractors and other third parties. “If you bring in a contractor who needs remote access, you don’t want them staying in the system forever,” Elattar explains. “Their access ends when their contract ends.”

With Conditional Access, IT and security managers can easily maintain company-wide oversight of TeamViewer access and usage from a single location.

Visibility and accountability

Zero Trust also demands traceability. With enhanced auditability, TeamViewer Tensor tracks every remote session in detail, including who connected, for how long, what they did, what was changed, and what files were transferred.

To strengthen compliance and simplify audits, Tensor can be set up to record sessions securely in the cloud. This provides complete visibility and documentation of all remote sessions.

Tensor also offers AI-powered Session Insights, which automatically summarize the actions taken during a support session.

“We provide a paper trail,” Elattar says. “Not just who’s connecting to what device, but also exactly what they do. With Tensor, every technician has proof of service. It’s faster to resolve problems and easier to confirm compliance.”

From IT to OT

Modern digital workplaces are highly connected, and the line between IT and OT (operational technology) is disappearing.

The challenge is that many OT systems still rely on old equipment. This creates serious security gaps.

“Factory machinery and industrial equipment are often running on software that hasn’t been updated for a long time,” says Elattar. “When you mix old technology with new, the security risks grow fast.”

Tensor’s zero trust features meet this challenge by offering secure remote access to OT equipment. As well as strictly controlling who can connect, when, and how.

Summary

Cyberattacks are becoming more sophisticated. At the same time, threat vectors are growing due to more endpoints, borderless networks, and increasing insider threats. As a result, traditional network security models are simply no longer enough.

By assuming a breach will happen, zero trust verifies every user, every device, every time. This approach is far better suited to the security challenges of today’s digital workplaces.

When it comes to remote access, TeamViewer Tensor delivers an industry-leading zero trust solution that combines single sign-on, Conditional Access, AES-256 encryption, and full auditability.

From IT to OT, it gives businesses complete control over who connects, what they can access, and how they interact with critical systems.
