The Quantum Threat on the Horizon
The 2025 Verizon Data Breach Investigations Report (DBIR) doesn’t mention quantum computing directly, but the writing is on the wall: we’re headed toward a future where today’s encryption will be tomorrow’s vulnerability. This year’s report highlights a cybersecurity landscape increasingly defined by automation, vulnerability exploitation, and third-party risk—factors that align uncomfortably well with the kind of disruption quantum computing could introduce.
Quantum computers capable of breaking current cryptographic standards aren’t here yet. But when they arrive, the ripple effects will hit hard. RSA and ECC, foundational encryption methods in much of today’s internet, email, and banking systems, are especially at risk. The threat isn’t just future data theft—it’s the “harvest now, decrypt later” (HNDL) attack already in play. Criminal actors are extracting and storing encrypted data today, betting they can unlock it when quantum capabilities mature.
Beyond Technology: The Supply Chain Challenge
Quantum security isn’t just about upgrading tech. It’s a supply chain problem. The report reveals that 30% of breaches involved a third party, and credentials stolen from one weak link often gave attackers the keys to entire systems. Imagine that, but with post-quantum vulnerabilities: one outdated cryptographic system in a vendor’s stack could compromise thousands of customers.
Your Quantum Security Roadmap
So, what does preparation look like?
First, inventory your cryptographic dependencies. Know where RSA or ECC are in use and begin transitioning to quantum-safe algorithms like those recommended by NIST’s post-quantum cryptography standardization process.
Second, build resilience into vendor contracts. Quantum readiness should be part of your third-party risk assessments. If you’re trusting a vendor with your data, you need assurance they’re future-proofing it.
Third, integrate quantum security into your IT roadmap. As the DBIR makes clear, tech debt—from legacy systems to insecure BYOD practices—opens doors. Don’t let outdated encryption be another crack in the wall.
Finally, stay informed. Cybersecurity isn’t static, and quantum breakthroughs could accelerate faster than expected. Collaboration across industries, shared standards, and regular assessments will be essential.
The Time to Act is Now
The 2025 DBIR paints a picture of an industry under pressure from sophisticated, fast-moving threats. Quantum computing will only amplify those pressures. The good news? We still have time to adapt. But that window is closing fast.
Quantum computing represents a paradigm shift that cannot be ignored. By integrating post-quantum readiness into your cybersecurity frameworks now, organizations can safeguard their data, maintain compliance, and stay ahead of potential threats. The quantum future may not be here yet, but the time to prepare for it is now.
