It is an essential part of the Telex Quality Promise that we provide product security and protect our customers’ privacy throughout the entire product life cycle. To achieve this Telex established a global Product Security Team and made security an integral part of Telex’s processes. The Product Security Incident Response Team (PSIRT) is the central point of contact for external security researchers, partners, and customers to report security concerns related to products of Telex.

Product Security throughout the life cycle of Telex's products & services

Security with Supplier

We have high quality requirements for purchased products. To ensure security of purchased products, modules and components we evaluate each supplier with respect to product security, as an integral part of our purchasing process.

Security Engineering Process

Security Engineering Process is a core part in our product development. Whenever we develop a new product, we conduct a comprehensive Threat and Risk Analysis, and create an individual Security Concept for the product and its integration into a complete solution. During design phase and before release we ensure product security by comprehensive testing (security and penetration tests). Any following updates, patches or upgrades will undergo the same rigorous tests, and will only be deployed once they have proven to be secure.

Vulnerability & Incident Management

Because requirements are constantly changing, 100% security is never guaranteed. Therefore a structured Vulnerability and Incident Management Process is established to professionally manage potential product security vulnerabilities and incidents.

Reporting Product Security Vulnerabilities

Telex takes security very seriously, and investigates all vulnerability reports.

Whenever you think you have identified a vulnerability or any other security issue related to a Telex product or service, please contact the Product Security Incident Response Team (PSIRT):
