Q&A: How TeamViewer strengthened security certifications in 2025

In 2025, TeamViewer expanded and renewed several independent security certifications across its product portfolio, from Remote and Tensor to DEX and Frontline.

We asked Patricia Leppert, Head of Customer Trust & Security at TeamViewer, why these validations matter and what they mean for our customers and our business.

Patricia Leppert: Certifications translate trust into something verifiable. When a healthcare provider, a public agency, or an enterprise security team evaluates software, they’re looking for evidence that our controls are designed, implemented, and continuously tested by qualified third parties.

Frameworks like ISO 27001 and SOC 2/3 set the foundation for an enterprise Information Security Management System; cloud-focused programs such as CSA STAR Level 2 and BSI C5 deepen transparency; and sector-specific standards — think HIPAA and DCB-129 in healthcare context or public sector baselines like NIST 800-53 and FedRAMP — show that our services align to the regulatory environments our customers operate in.

Ultimately, these certifications demonstrate that TeamViewer has already implemented the necessary security and compliance controls and that they are operating effectively. Independent audits provide objective validation of the safeguards we have in place, giving customers confidence that they are reducing risk when using our products. Not because of the certification itself, but because the underlying controls have been designed, implemented, and continuously improved to meet these standards.

Patricia Leppert: Two themes stood out: breadth and depth. We renewed core attestations across the portfolio and company, such as ISO 27001 and SOC 2/3. This keeps our baseline strong across our entire product portfolio and our own operations at TeamViewer as a company.

At the same time, we strengthened cloud assurance and coverage in regulated sectors. CSA STAR Level 2 was added across our cloud products; Tensor achieved BSI C5 certification, which is especially relevant for cloud and healthcare use in the DACH region; and Frontline obtained DCB 0129 for clinical safety assessment in healthcare which is specifically important in the UK and Commonwealth.

On the public sector side, our DEX solutions advanced with two important milestones focused on the US market, with the NIST 800-53 reattestation and our continued FedRAMP journey.

Together, that mix signals maturity, as we’re not just checking boxes but building a compliance footprint that matches where our customers actually work.

Patricia Leppert: For customers, it means less friction and more confidence. Certifications and attestations conducted by independent third parties shorten procurement cycles, ease onboarding, and provide auditors with the artifacts they need. For TeamViewer, it’s a commitment to Security-by-Design, meaning that we continuously evolve our controls and broaden coverage where our customers need it most, such as healthcare, government, or highly regulated industries. 

Our aim is to pair TeamViewer’s digital workplace solutions with independently verified security, so organizations can scale with us without compromising trust.

Patricia Leppert: We use a compliance management tool to scale and automate as many processes as possible. That’s an ongoing process, we have the next audits already in the pipeline.
