Today’s encrypted corporate data, including high-value access credentials, may no longer remain confidential in the future as rapid advancements in quantum hardware threaten to break the public-key cryptography protecting them. Although current computing systems cannot compromise widely used algorithms like elliptic curve cryptography or RSA, electronic attackers are actively deploying a strategy known as “Harvest Now, Decrypt Later”. Under this tactical model, cybercriminals capture and store encrypted data packets today, intending to decrypt the information as soon as commercial quantum computing catches up.
Security Timelines Shift as Q-Day Deadlines Approach
According to the Global Risk Institute’s 2025 Quantum Threat Timeline report, security specialists believe a cryptographically relevant quantum computer is likely to be available within the next 15 years, with 51 to 70 percent of surveyed experts indicating this probability. This looming milestone, widely referred to as “Q-day,” has prompted government agencies to establish strict compliance deadlines.
The National Security Agency (NSA) has announced that its Commercial National Security Algorithm Suite 2.0 will require new national security systems to support quantum-resistant algorithms starting January 1, 2027. While deadlines are staggered for various system categories through the early 2030s, the NSA plans to make all national security infrastructures quantum-resistant by 2035. Concurrently, the National Institute of Standards and Technology (NIST) is advancing draft IR 8547, which deprecates RSA-2048 and ECC P-256 after 2030 and disallows them entirely after 2035.

Machine Identities Emerge as Primary Quantum Risk
Experts warn that not all encrypted data carries the same degree of systemic risk. While corporate secrets like session tokens carry a confidentiality lifetime measured in months, organizational credentials can persist for years as long as their associated core systems remain in active service. This persistence makes credentials the primary target for malicious harvesting operations.
The security risk is amplified by the massive scale of modern network architectures, which feature rapidly growing populations of Non-Human Identities (NHIs) such as service accounts and API keys. Because no human operator is responsible for rotating these automated machine credentials, they are rarely inventoried for cryptographic exposure, making them ideal targets for external intercept networks.
Strategic Blueprints for an Agile Migration
Because full enterprise cryptographic migration can take anywhere from 5 to 15 years due to the discovery phase alone lasting up to two years in large organizations, specialists advise taking an immediate, credential-first migration path. The transition blueprint requires enterprises to thoroughly inventory their existing cryptography by locating systems that broker secrets, including password managers and Privileged Access Management (PAM) platforms, which frequently unearth forgotten or dormant service accounts.
Security leaders recommend that companies prioritize risk exposure over database size, focusing on small, long-lived secrets that broker access to critical infrastructure rather than vast but short-lived datasets. Furthermore, organizations are urged to adopt hybrid cryptography, combining classical public-key infrastructure with quantum-resistant components in the same key exchange. This preserves traditional defenses while allowing systems to remain agile when future algorithms undergo deprecation. In response to these emerging threats, technology firms have begun updating client software; notably, the rollout of post-quantum protections began across all Keeper client applications in November 2025, adopting Kyber Hybrid Key Encapsulation Mechanisms to secure digital vaults.
