Our Commitment to Cybersecurity

Today, vast amounts of sensitive patient information and data are kept within the modern healthcare provider network. For Varian and its customers, cybersecurity is a top priority. Together, we have a shared responsibility to maintain robust end-to-end defenses that keep systems secure.

Our products and services are developed with a focus on quality and patient safety. We continue to improve and extend the security measures for our current products. As threats and associated risks are evolving, not all statements on this page apply to all products and services. Contact your local Varian representative for further details.

We collaborate with vendors and healthcare providers to promote true end-to-end cybersecurity, helping to ensure that our products are safe and secure, with access restricted to authorized users. We take cybersecurity extremely seriously, and collaborate with others in the healthcare and technology industries to minimize data security breaches and protect patients.

Coordinated Vulnerability Disclosure

Varian encourages everyone to report vulnerabilities, regardless of service contracts or product lifecycle status. We welcome vulnerability reports from researchers, industry groups, CERTs, partners, and any other source. Varian respects the interest of the reporting party (also anonymous reports if requested) and agrees to handle any vulnerability that is reasonably believed to be related to Varian products or components. Varian urges reporting parties to perform a coordinated disclosure, as immediate public disclosure causes a ‘0-day situation’ which puts our customer systems and client hospitals at unnecessary risk.

Reporting Process

Varian currently follows the Siemens AG process for Coordinated Vulnerability Disclosure. For a more detailed description of the process please visit the Siemens Vulnerability Handling and Disclosure Process website.

State-of-the-art system software

Rapid advances in healthcare technology can make your medical equipment become outdated prior to useful life of the product. With our Varian Service PremierAssurance service agreements, we can help you keep your Varian equipment updated and cybersecure throughout its product lifespan. Choose from a range of service levels and entitlements to cover your regulatory and financial needs. For products that are not eligible for our PremierAssurance program, we offer other service contracts. For more information, please visit our Services page.

Data Privacy

Protecting the privacy of your data is very important to us. We follow privacy principles and practices as part of “privacy by design” as we develop and release products and solutions. That means we implement various administrative, physical and technical measures in our products and solutions with the goal of enabling customers to comply with privacy laws (in particular HIPAA Privacy and Security rules in the United States and GDPR in the European Union and the European Economic Area) when customers process protected health information and other personal data while using our products and solutions.

Safeguarding Patient Information

Data analytics and cloud-based, mobile solutions offer huge promise for human-centered cancer care, unlocking useful tools for both physicians and patients. For example, our noona® app allows patients to actively engage with their cancer care team and report outcomes, providing oncologists with the potential to analyze data and change research and treatment protocols in real-time. noona is certified to ISO/IEC 27001:2013, the internationally recognized security certification, indicating the paramount importance we place on maintaining the integrity of information in our care.


We publish security advisories and bulletins on an ongoing basis to notify you about any validated security vulnerabilities pertaining to Varian products. Mitigation may involve applying an update, performing an upgrade, or other actions on your part. Please visit MyVarian for more information.
