Question 7
Which of the following companies is NOT mentioned as a provider of unidirectional gateways?
- A Owl
- B Cisco
- C Waterfall
- D Nexor
Reveal correct answer
Correct answer: B
Explanation
Companies like Waterfall, Owl, and Nexor are recognized providers of unidirectional gateways, specializing in data diodes for secure, one-way data transfer in industrial and critical infrastructure environments. Cisco, however, is primarily known for networking equipment like routers, switches, and firewalls, not for manufacturing unidirectional gateways. While Cisco offers cybersecurity solutions, it is not typically associated with data diode technology, distinguishing it from the other listed companies.Discussion
