Layer 2 vs. Layer 3 Quantum-Safe Encryption: Which Do You Need?

jani.virkkula@ssh.com (Jani Virkkula) — Wed, 23 Sep 2026 07:55:07 GMT

Once an organization accepts that data in transit needs quantum-safe encryption, the next question is architectural: where in the network stack should that encryption actually happen?

The EU Post-Quantum Cryptography Roadmap: Deadlines and What They Mean for Critical Infrastructure

jani.virkkula@ssh.com (Jani Virkkula) — Tue, 22 Sep 2026 12:26:28 GMT

For most of the last few years, “the EU is moving toward post-quantum cryptography” was a directional statement, not a deadline.

Preparing Networks for the Next Algorithm Transition

Most conversations about post-quantum migration are framed as a single decision: which algorithm do we move to. That framing is already out of date by the time the migration finishes.

Harvest now, decrypt later: why your traffic is already at risk

No quantum computer today can break the encryption protecting your network traffic. That fact gets repeated so often it's easy to hear it as reassurance. It isn't one because breaking the encryption is not the step an adversary needs to take right now.

Quantum-safe network encryption explained: protecting data in transit at scale

jani.virkkula@ssh.com (Jani Virkkula) — Tue, 22 Sep 2026 10:04:55 GMT

A cryptographically relevant quantum computer that is capable of breaking the public-key cryptography and that secures most network traffic today doesn't exist yet. Nobody is certain when it will. But the risk to your organization’s data doesn't depend on that timeline. It depends on how long your data needs to stay confidential.

Cyber Defense Strategy: The DoD Perspective

jani.virkkula@ssh.com (Jani Virkkula) — Mon, 29 Sep 2025 10:43:54 GMT

Cyber attacks today target military systems, critical infrastructure, and global supply chains. Adversaries use advanced tools to disrupt missions and gain an edge in conflicts. You need a clear plan to respond to these threats and protect national defense.

What Is Space Cybersecurity? Key Challenges & Strategies

jani.virkkula@ssh.com (Jani Virkkula) — Mon, 29 Sep 2025 10:43:53 GMT

Space systems are now prime targets for cyberattacks. Hackers can intercept satellite links, disrupt drone operations, and compromise ground servers. These attacks put navigation, defense, and communication at risk.

Satellite Cybersecurity: Threats & Impacts

jani.virkkula@ssh.com (Jani Virkkula) — Mon, 29 Sep 2025 10:43:52 GMT

Cyber attacks on satellites are no longer a distant possibility. From disrupted GPS signals to hijacked communication networks, attackers have already shown how vulnerable space assets can be. These systems support the internet, navigation, defense, and critical infrastructure on Earth, which makes them high-value targets.

Military Grade Encryption Explained

jani.virkkula@ssh.com (Jani Virkkula) — Mon, 29 Sep 2025 10:43:38 GMT

Data breaches, cyber espionage, and advanced attacks are growing risks for governments, defense forces, and industries handling sensitive information. Standard encryption alone can’t meet the security needs of systems that must protect secrets for years or even decades.

Air Force Cyber Security: Key Threats and Solutions

jani.virkkula@ssh.com (Jani Virkkula) — Mon, 29 Sep 2025 10:43:37 GMT

Cyberattacks are no longer limited to stealing data. They can ground aircraft, disrupt fuel systems, or even hijack drones during live missions. When adversaries target the digital backbone of defense, they aim to weaken national security without firing a shot.
