Johnson Controls launches Tyco Software House iSTAR Ultra G2 iSTAR

JOHNSON CONTROLS has launched Tyco Software House iSTAR Ultra G2, a next generation door controller designed for cyber resiliency, providing end user customers with faster processing power, advanced enterprise functionality and the building blocks needed for future expansion.

Ideal for mid-size through to large-scale deployments in higher education, healthcare, Government, Data Centre, industrial and manufacturing facilities, the iSTAR Ultra G2 is a highly flexible door controller, supporting both wired and wireless locksets, with expanded memory capacity designed to ensure the device grows with customer needs.

It can manage up to one million credentials for up to 32 doors. Advanced enterprise features such as dual GigE network ports using TLS 1.3 network authentication and cluster-based, anti-passback deliver the power to handle the most demanding of access control applications.

The iSTAR Ultra G2’s advanced hardware-based cyber security protection using Trusted Execution Environment (TEE) means that this solution assures confidentiality of code and data to help combat the most sophisticated hackers. The TEE guards against cyber attacks, while the OSDP Secure Channel communication standard provides encrypted two-way communication between devices (including readers and controllers).

Expanded portfolio

“The addition of the iSTAR Ultra G2 expands our portfolio of door controllers to include one of the most expandable solutions available in the market,” said Rick Focke, director of product management for enterprise access control security products at Johnson Controls. “This device is an important solution for end user customers who need a highly scalable and cyber-resilient solution that serves as the heart of the access control system, connecting readers, sensors, software and locking devices.”

On-board Public Key Infrastructure authentication services mean that the iSTAR Ultra G2 is a self-contained, high-assurance solution and does not require third party devices for authentication, thereby saving money and installation time.

Global and peer-to-peer, anti-passback technology prevents consecutive entries from single access control cards in order to keep multiple people from using the same credential.

iSTAR Ultra has been built using the Johnson Controls ISASecure certified development process in accordance with the ISA/IEC 62443 control systems security standard and includes a back-up communication path in the event of a primary network failure to eliminate system downtime.

Additionally, iSTAR Ultra G2 uses the same form factor as other iSTAR door controllers such that it fits easily into existing control panel boxes.
