TK Elevator, Germany headquarters, and all branches worldwide.KeyTalk CKMS, certificate based device authentication (DA) for all user devices through integration with Intune - Private root certificates from GlobalSign are used with a connection via KeyTalk CKMS.

TKE, independent since 2021 after the sale from the former Thyssen Krupp parent company. Their slogan “Engineering that keeps the world moving.” This is what TKE tells about themselves:

“We are driven by what moves people. By what moves the world in ever-growing cities. We provide better access and new ways to travel longer distances. With clear solutions for increasingly complex infrastructures. We work with a service-oriented approach and always use our knowledge for the benefit of our customers. We strive for improvement, every day anew. This is who we are. This is TK Elevator. Engineering that keeps the world moving.”

TKE was looking for a cloud-based certificate management solution to provide its 30,000+ workstations at over 1,000 locations worldwide with short-lived authentication certificates. The three-year contract for the KeyTalk CKMS, which automates the installation and renewal of GlobalSign machine certificates on all workstations every 25 days, is one of the largest contracts for KeyTalk.

At TKE, a solution based on a private root from GlobalSign is provided. Through integration with the GlobalSign Atlas platform, the certificates are managed by the KeyTalk CKMS and then further distributed to MS Intune for installation on various devices, including Windows, Mac OS X, Android, and iOS. The usage is growing daily, with ultimately more than 40,000 devices being supported.

In 2022 we won, together with our global partner DigiCert, a European tender issued by TenneT TSO.  Besides all kind of digital certificate issuance for document signing, codesigning and TLS/SSL certificates, the primary use case was to support and manage the 15.000+ S/MIME certificates needed for the coming 5 years. Crucial was the full automation of request, enrollment and configuration of the S/MIME certificates on the new standardized Windows/365 workstations and laptops and a seamless integration with MS Intune for deploying identical S/MIME certificates to mobile devices.

Because of the successful relationship KeyTalk was asked to also provide a device authentication solution for 5.000 user/devices of the German branche of TenneT, to replace a physical token solution.

Hermeus, USAKeyTalk Secure Email Service (SES) including DigiCert class 2 enterprise S/MIME certificates

Hermeus is an aerospace and defense technology company founded to radically accelerate air travel by delivering hypersonic aircraft.

The company aims to develop hypersonic aircraft quickly and cost-effectively by integrating hardware-rich, iterative development with modern computing and autonomy.

This approach has been validated through the design, build, and test of the company’s first combined turbojet-ramjet engine and is now being scaled through its first flight vehicle program, Quarterhorse.

Hermeus is also developing Darkhorse — an uncrewed hypersonic aircraft designed to deliver unique asymmetric capabilities to the warfighter.

Hermeus was looking for standardized S/MIME automation and management capabilities for end-to-end encryption of all it’s email. Where the normal manual support offered by DigiCert resulted in an overflow of support from the Hermeus IT department, with the adoption of the KeyTalk Secure Email Service, the same DigiCert S/MIME certificates were now automatically requested, deployed and configured to work with MS365 Outlook. Even changes in personnel are automatically detected by KeyTalk’s EntraID interface, so new S/MIME certificates are enrolled automatically or archived when someone leaves the company. For integration with the mobiles, the KeyTalk interface to MS Intune’s PFX connector is used.

Visit the Hermeus website for more information on their daring ambition for hypersonic flights.
