Quantum-safe cryptography 

Adversaries don’t need a quantum computer to start attacking your data. Encrypted traffic intercepted today can be stored cheaply and decrypted the day quantum computing matures. Regulations demand you start building your crypto inventory.

Powerful quantum-safe security solutions

Some data will outlive your encryption

If your data must stay confidential for ten years or more, the exposure to Harvest now, decrypt later (HNDL) attacks began the moment it crossed a network. Examples of such data include:

  • classified material
  • diplomatic correspondence
  • patient or medical records
  • intellectual property
  • financial transactions
  • OT telemetry, OT infrastructure details and login credentials

The systems that matter most can't be upgraded

Protected by default

Browsers, email, and cloud services are updated on a vendor's schedule in the background.

Exposed for years, possibly forever

Legacy applications and IT on proprietary protocols. OT and ICS with decades-long lifecycles. Embedded devices without the compute for post quantum algorithms. Third-party connections your organization doesn't control.

The post-quantum cryptography (PQC) transition has deadlines

Across Europe, the United States and Asia-Pacific, governments and regulators have put dates on the move to quantum-safe world. Typically, the recommend post-quantum cryptography as the method.

Your first practical steps to becoming quantum-safe

1. Protect data in transit against harvest now, decrypt later 

Critical organizations have the obligation to protect long-lived data against present and future threats. The good news is your organization does not need a market-wide quantum-safe rollout or a finished standard to get going. You also don’t need a finished inventory to start. 

With quantum-safe network encryption, you build resiliency and protect data in transit against harvest now, decrypt later while building your inventory. With a network encryptor like NQX, you can:

embed any data traffic inside a quantum-safe overlay at the network level (L2/L3)

protect all traffic, starting from the network backbone all the way to the application layer

secure app-to-app, site-to-site, data center to data center connections over untrusted networks with a single solution

keep your infrastructure intact and quantum resilient

2. Start your discovery phase with an SSH crypto inventory

Creating a crypto inventory of your entire tech stack and Cryptographic Bill of Materials (CBOM) is a big task that might take years. Start your discovery phase with a Secure Shell inventory: Discover and inventory your SSH keys and cryptographic assets, assess their crypto-agility level, and understand where to prioritize your migration to PQC - with guidance from the inventors of SSH.

01 Prioritize data in transit

It's where harvest-now-decrypt-later hits first, and where protection can be added without changing systems

02 Require crypto-agility

In anything you procure, so evolving standards never force a rip-and-replace upgrade.

03 Align with your mandate

EO deadlines, NIS2, DORA, ECB supervisory expectations — know which applies and what evidence you'll need to show.

04 Inventory

While protecting data in transit, build your inventory and Cryptographic Bill of Materials (CBOM).

05 Map exposure

Which sensitive data crosses which links, and how long must it stay confidential?
