🛠️ Network Engineers & Security Teams: Remember when passive decryption with RSA key exchange made traffic visibility simple?

TLS 1.3 changed the game with mandatory ephemeral Diffie-Hellman. No more passive decryption. Every visibility point now needs an inline device.
The math is sobering:

10 visibility points = 10 potential failure points
Each device failure = broken TLS sessions
Result? Increased complexity and decreased reliability

But here's where it gets interesting... NIST's new project explores innovative approaches like controlled static DH keys and ephemeral key export agents.

Want to understand how these solutions could transform your visibility architecture?

Part 1 – Passive Inspection of TLS 1.3 Within The Enterprise This blog is the first in a series that looks at a NIST project, “Addressing Visibility Challenges with TLS 1.3 within the Enterprise.

OT security teams face a dilemma:
• Air gaps: Secure but impractical
• Firewalls: Practical but vulnerable
• Hardware Data Diodes: The sweet spot?

Traditional data diodes have mostly been confined to high-security facilities, but they're now gaining traction in private and OT networks.

What makes Hardware Data Diodes different from both firewalls and traditional data diodes? We break it down in our latest article: https://hubs.la/Q03h-qWq0
