How security is a foundational principle at TeamViewer

Static point solutions often can’t keep up with how large organizations actually operate. This is because threats change constantly, regulations are updated regularly, and IT networks now involve thousands of individual connections that all need to be validated. However, solutions built for simpler times can leave as many gaps as they close.

That’s why TeamViewer does not treat security as a separate layer or an added feature. Security is part of our DNA. It informs how we design products, how our teams work, and how we build trust with our customers.

Building security into every TeamViewer product  

Security by design begins with architecture. At TeamViewer, we believe protections must be integrated from the earliest stages of development, not bolted on afterwards.

Take our corporate and production environments. Security considerations shape everything from server configurations to data flows. The same principle applies to our remote access solutions, where compliance and enterprise safeguards are embedded in the core architecture rather than added as patches later.

Our certifications and regular audits validate this approach.

Compare this to bolt-on security models, where every additional layer creates new complexity. Users face more hurdles. Systems become harder to maintain. And ironically, the very protections meant to keep things safe often become vulnerabilities themselves, because they weren't designed to work together from the start.

How culture shapes TeamViewer’s secure practices  

Technical safeguards are only as strong as the culture that supports them. At TeamViewer, secure practices are part of daily work across all departments, not confined to one team. Everyone has a role to play, and this collective responsibility is what makes safeguards effective in practice—this starts from an employee’s first day of onboarding.

Two programs highlight this approach:

• Security Champions: employees across the company who champion secure behavior in their daily responsibilities.
• Security Advocates: developers who take an active role in identifying and mitigating risks during the software development lifecycle.

“The Security Champion program makes security feel easy and practical. I appreciate the knowledge sharing within all departments and the great support for all kind of questions.”—Anne Spitzner, Senior Legal Counsel and Security Champion at TeamViewer

Both programs are supported by ongoing training and internal campaigns that strengthen awareness and communication. The result is a culture where security is not a checklist item but a consideration at every decision point, from the earliest stages of designing a solution through to deployment.

Openness to external input is another way this aspect of our culture is strengthened. By participating in hackathons and events like NULLCON, we deliberately expose our systems and practices to outside experts. We are also part of the Zero Day Initiative, a program that incentivizes discovery and responsible reporting of software vulnerabilities, and work together in addition to conducting our pen tests, external audits, and certifications. This willingness to invite scrutiny reflects our belief that safety comes first, last, and always, and that real security means being open to constant improvement.

Earning your trust through transparency  

We understand that trust requires more than good intentions; it demands transparency and accountability, as well as proactivity to disclose vulnerabilities and prevent their exploitation. That’s why our dedicated Customer Trust and Security Team focuses specifically on building customer-centric security practices that go beyond compliance requirements.

This team works proactively to safeguard your data and maintain accountability across all departments. Their mission centers on creating a unified security framework that serves customer needs, not just regulatory requirements.

Transparency shows up in our practices:

• Public security bulletins that disclose vulnerabilities with severity ratings and detailed patch instructions
• Bug bounty programs and rigorous testing methods that welcome external security research
• Subscription-based updates that provide real-time alerts to customers

This openness builds credibility over time. Rather than hiding behind security through obscurity, we believe that transparent communication about vulnerabilities and fixes strengthens trust and helps you make informed decisions.

From principle to practice  

When security is treated as part of the foundation, not a layer on top, it changes how organizations operate.

The principles of secure design and culture only matter if they hold up under real pressure. For the NHS in North West London, that pressure is constant. Hospitals and clinics depend on technology that works reliably, but they also operate under some of the strictest data protection and compliance rules in the world. Every connection has to be secure by default.

By using TeamViewer Tensor, the NHS doesn’t have to choose between speed and safety. Because they can access and manage servers at the click of a button. Compliance requirements are met, while care teams still connect without friction.

“With TeamViewer Tensor, we have the ability to centrally manage and patch connected devices, as well as respond quickly to cyber security incidents. This is invaluable as we strive to protect our employees, patients and provide the best care possible.”—Raj Tarafder, Senior Service Desk Analyst at NHS NW London CCG

At Bühler, the stakes are very different, but the story is the same. Their engineers support machinery spread across more than 140 countries. So remote access is essential, but early tools they used were unreliable, hard for technicians in the field to operate, and left gaps in auditing.

But using TeamViewer Tensor, Bühler was able to make remote support both dependable and accountable. What began as a security requirement for certification became a framework that also improved usability for technicians and consistency across sites.

Security is part of our DNA

Security at TeamViewer isn’t something added at the end of development or treated as a compliance checkbox. It’s part of how our products are built, how our people work, and how we maintain your trust.

By combining architecture that bakes in safeguards, a culture where every employee has a role to play, and transparency that makes risks and fixes visible, we’ve created a foundation customers can rely on. This foundation does more than safeguard systems—it enables organizations to operate with confidence, even where the stakes are highest.

Security is not what we build after the fact. It’s part of who we are.
