‘Harvest now, decipher later’: The quantum threat few are preparing for
Quantum technology may feel far off but certain risks are already with us in the form of “harvest now, decrypt later” — an attack vector in which malicious actors steal data now for a future in which they have access to quantum computational tools capable of breaking encryption deployed by most companies today to protect their data.
Despite increasing discussion surrounding this issue, not all organizations are aware of the risk. According to a 2025 ISACA survey, only 5% of cyber professionals considered the threat a high priority, despite two-thirds being concerned about quantum’s future ability to break encryption. That 5% was the same percentage of organizations that had defined a strateg...
