The Quantum Countdown: Is the C-Suite Prepared?
Quantum computing has lingered at the periphery of enterprise technology for years, yet its implications for cybersecurity remain an urgent discourse among industry leaders.

Nick Kathmann, CISO at LogicGate, recalls the early days of his computer science studies, noting that the promise of quantum computing was already on the horizon in 1998. “Even now, it feels like a distant concern,” he said, reflecting a widespread sentiment among technology executives.
Conversely, Donald Welch, CIO at New York University, expresses a different stance, stating, “It’s so low on my priority list that I haven’t given it much thought.” This divide underscores the spectrum of preparedness for a post-quantum security landscape—where some view it as an immediate necessity and others as a non-urgent matter.
According to Dan Wilkins, CISO at the Arizona Department of Economic Security, proactive preparation is critical, emphasizing, “We will have to adapt sooner or later, regardless of our preferences.” The uncertainty surrounding when quantum computers will compromise established encryption mechanisms, like RSA, leaves many organizations at a crossroads.
Framing the Threat: Business Implications
Anand Oswal, EVP of network security at Palo Alto Networks, frames post-quantum cryptography as a business risk masquerading as a technical issue. He warns that the potential collapse of foundational cryptographic practices could unravel the “invisible shield” safeguarding everything from financial transactions to national security.
Wilkins further elaborates on the urgency regarding “harvest now, decrypt later” attacks—a reality that particularly concerns organizations handling extensive amounts of personally identifiable information. “The chilling risk emerges when this sensitive data is protected by existing technologies, which may not hold up against quantum advancements,” he stated.
Delaying action until quantum breakthroughs are indisputable could force organizations to navigate an overwhelming crisis response. Oswal notes the complexities of cryptographic migration, which often requires significant time—spanning five to ten years to effectively implement changes across vast enterprise ecosystems.
Identifying the Preparedness Gap
Industries beginning to prioritize quantum readiness are typically those with sensitive, long-term data or those in highly regulated sectors. Analysts like Sandy Carielli from Forrester suggest early adopters will likely emerge from government and financial sectors.
Venice Goodwine, CIO at Arlo Solutions, emphasizes that defense organizations lead this charge due to their heavy reliance on cryptography. “Our adversaries are consistently seeking vulnerabilities, and quantum resilience is integral to maintaining our security posture,” she asserted.
Despite the mounting pressures from initiatives in artificial intelligence and geopolitical challenges, many executives continue to prioritize other issues over quantum preparedness. As Gartner analyst Nauman Abbasi points out, quantum technology will remain on the back burner until a significant breakthrough occurs.
However, inaction poses severe risks. Carielli warns, “Waiting too long may leave your data vulnerable—if you hesitate, others will notice and exploit these weaknesses.”
Charting a Path Forward
For organizations at the onset of their quantum readiness journey, experts recommend conducting an asset inventory as an initial step in evaluating vulnerabilities. Wilkins corroborates this approach, stating, “Understanding your data environment is essential for informed decision-making.” This starts by assuming data is already compromised and refining strategies based on that premise.
The pervasive nature of cryptography complicates establishing a risk baseline, as many applications and systems are deeply integrated with this technology. Oswal notes that most CIOs may find this task daunting, but it remains an essential starting point.
Not all data requires equal attention. Teams should focus on encrypting the most sensitive, long-standing records rather than adopting a blanket approach. Wilkins advises against the complacency of blindly encrypting all data, as it may preoccupy resources that could be better allocated.
Threat modeling further enhances preparedness by aligning security measures with the value of the data at risk, a point emphasized by Kathmann. “A proper threat model ensures appropriate strategies are in place,” he remarked.
As organizations embark on their quantum readiness efforts, they must engage technology vendors to ensure alignment in their strategic timelines. Wilkins points out that collaboration with certificate authorities and other providers is crucial to maintaining a cohesive quantum roadmap.
For Carielli, beginning this critical preparation is essential, even for companies that currently perceive minimal immediate risk. Government organizations, like the National Institute of Standards and Technology (NIST), are already issuing timelines and guidance to encourage proactive measures in post-quantum migrations. “This guidance may eliminate the luxury of delay,” she concluded.
