1. Build a Business Case

Make sure you start with preparing a list of tangible impacts to your business with the emergence of post-
quantum threats. Also, calculate the ROI of implementing a proactive plan of action before the threats
reach your organization’s door.

2. Evaluate and Analyze the Threat Perception

Make sure you first understand the at-risk data and processes with respect to quantum computing. This
will help you zero in on the post-quantum cryptographic systems that will address a rapidly evolving threat
landscape.

3. Asset Prioritization

Create an inventory of the various security protocols used in your organization, including encryption
frameworks. Also, create a list of assets that you feel are most susceptible to post-quantum threats.

4. NIST Standards

NIST has already released the list of recommended post-quantum cryptographic standards. Understand
these and check how you can begin the implementation process.
5. Begin the Quantum-Safe Journey

Every journey begins with small steps. Methodically start transitioning to a quantum-safe cybersecurity
posture. Update your software and hardware, and modify legacy systems. Also, have replacement
timelines for systems in place.

6. Continuous Risk Assessment

Your roadmap will evolve as the years go by. New information on post-quantum threats and new solutions
will be available. Keep evaluating existing high-risk areas, security protocols, and make incremental
improvements.

Final Thoughts

The battle against cyberthreats is won or lost based on your proactive approach (or the lack of it). We
are well aware of how organizations dropped the ball on security and experienced an expensive data
breach. Do not be that organization. Start taking action and start moving towards post-quantum
cryptography to keep your data safe.
