This brochure addresses common questions about Owl data diodes used in critical infrastructure environments. It explains that while data diodes and firewalls share some security functions, they are fundamentally different. Firewalls rely on software rules, policies, and filters to manage access, whereas Owl data diodes enforce security through immutable, hardware‑based mechanisms governed by the laws of physics and cannot be altered through software. Because of this, data diodes offer a higher level of assurance against cyber threats. The brochure also notes that data diodes do not necessarily replace firewalls but can work alongside existing firewall deployments to strengthen overall security architecture and protection strategies.
