The future of cybersecurity is not one breakthrough technology or a single new threat. It is a shift in how organizations manage cryptography, software, identities, connected devices, infrastructure, and risk—while adapting to AI. Some preparation is already actionable: NIST says three post-quantum cryptography standards are finalized and ready for implementation. The timing of future quantum capabilities and AI’s net effect on cyber jobs, however, remain uncertain.
What is changing in cybersecurity?
Cybersecurity is moving from a model centered on protecting individual systems toward one that must also manage dependencies and change across entire environments. Cryptographic algorithms are embedded in applications, protocols, hardware, firmware, and infrastructure. Software depends on suppliers and components beyond an organization’s direct control. Identity and access decisions affect connected services and devices. AI adds new possibilities for defensive analysis, while raising questions about how cyber work and training will evolve.

NIST’s FY 2025 cybersecurity program report groups work across cryptography, cybersecurity and AI, education and workforce, hardware and software security, infrastructure security, and risk management. Its FY 2024 report also describes work on software and supply-chain security, IoT guidance, identity and access management, and autonomous-vehicle security. Together, these areas show why the future agenda is broader than AI and quantum computing: NIST’s FY 2025 report and NIST’s FY 2024 report.

A sufficiently capable future quantum computer could undermine some cryptographic methods used today. That possibility does not establish when such a computer will exist or when it will be able to compromise systems in practice. The practical point is narrower: changing cryptography across a large organization takes planning, so organizations can start identifying dependencies before a future deadline is known.
#1 Best Overall
NIST says three post-quantum cryptography standards have been finalized and are ready for implementation. That makes preparation more than a research exercise: organizations can assess where vulnerable algorithms are used and plan for replacements or updates using published standards. NIST’s post-quantum cryptography guidance is the starting point for its standards and related information.
Begin with discovery, not a blind replacement
Cryptography can be buried in software, services, devices, and supplier-provided components. A useful first step is to build an inventory of cryptographic use across applications, protocols, hardware, firmware, and infrastructure, then identify which systems depend on algorithms that need to be replaced or updated. Treat this as an ongoing asset and dependency exercise: an inventory that omits a supplier or an older system cannot support a complete migration plan.
Plan for service continuity
Replacing a cryptographic algorithm is not just a configuration change. Teams need to know which applications and partners depend on it, how updates will be tested and deployed, and what the operational consequences could be. Prioritize work through the organization’s risk-management process, with attention to the systems and dependencies that matter most to continued operations.
Crypto agility makes migration manageable
Finding vulnerable cryptography is only part of the challenge. Organizations also need the ability to change cryptographic algorithms without putting security or ongoing operations at risk. NIST describes this capability as crypto agility: adapting algorithms across protocols, applications, software, hardware, firmware, and infrastructure while keeping systems secure and running. Its CSWP 39 announcement sets out that broad, organization-wide perspective.
Crypto agility is best understood as an architectural and operational capability, not a promise that every system can be changed instantly. It depends on knowing where cryptography is used, understanding dependencies, and having a controlled way to update components. When planning a migration, evaluate four questions:
- Coverage: Does the inventory include the relevant algorithms, systems, protocols, and suppliers?
- Operational impact: Can updates be made while preserving security and ongoing service?
- Risk-management fit: Are migration priorities connected to the organization’s established risk frameworks and controls?
- People and skills: Do the teams responsible for design, procurement, operations, and security have the knowledge to carry out and maintain the changes?
AI may assist defenders, but its workforce impact is unsettled
AI can potentially support defensive work by helping analyze data or detect network anomalies. These are examples of possible uses, not proof that AI can independently secure an organization or replace security teams. NIST’s discussion of AI and cyber work also makes clear that education and workforce effects are still being considered; available evidence here does not establish a net number of jobs AI will create or eliminate. See NIST’s discussion of AI’s impact on the cybersecurity workforce.
Rank #3
For organizations, a sensible approach is to treat AI as a capability to assess and govern. Consider where data analysis or anomaly detection could help a team, how people will review and act on results, and what training is needed to use such tools responsibly. Keep ownership of security decisions clear rather than assuming that automated analysis resolves the underlying risk.

The wider agenda: software, identity, devices, and infrastructure
Technology change does not remove familiar security responsibilities. NIST’s program reports point to connected areas of work that organizations need to consider alongside cryptography and AI.
Software and supply chains
Software security includes dependencies on components and suppliers, not only code written in-house. Organizations should understand which external software and services their systems rely on and include those dependencies in security and risk decisions. NIST’s FY 2024 report identifies software and supply-chain security among its areas of work.
Identity and access
Identity and access management determines how people and systems reach organizational resources. It remains a core part of cybersecurity as environments and dependencies change. NIST’s FY 2024 report includes identity and access management in its research and guidance areas.
IoT, vehicles, and infrastructure
Connected devices and specialized systems can create security needs that differ from those of conventional business software. NIST’s FY 2024 report covers IoT guidance and autonomous-vehicle security research, while the FY 2025 report includes hardware and infrastructure security. These topics underline the need to account for the systems an organization actually operates, rather than assuming one control set fits every device or environment.

A practical readiness program can connect these topics without pretending that every future risk is predictable. The sequence below turns standards and established areas of work into organizational tasks:
Best Value
- Map dependencies. Inventory cryptographic use, software and supplier dependencies, identities and access, connected devices, and critical infrastructure.
- Set priorities through risk management. Identify which systems and services deserve attention first, and connect those decisions to existing risk frameworks and controls.
- Plan cryptographic updates. Use NIST’s finalized post-quantum standards as the basis for assessing algorithms that need replacement or updating, and account for affected systems and suppliers.
- Build change capability. Assess whether teams can update cryptography across protocols, applications, hardware, firmware, and infrastructure while maintaining secure operations.
- Evaluate AI with human ownership. Consider bounded defensive uses such as data analysis or network anomaly detection, and define how staff will review outputs and make decisions.
- Develop skills alongside technology. Ensure that security, operations, software, and procurement teams understand their roles as cryptographic practices and AI use evolve.
What remains uncertain
Standards and organizational preparation are concrete; exact timelines for future quantum capabilities are not established here. Nor does the evidence support a quantified forecast of AI’s net effect on cybersecurity employment. A peer-reviewed 2024 review by Yi-Kai Liu and Dustin Moody also discusses possible future uses of quantum technology to enhance cybersecurity, including research into device-independent random number generation and quantum key distribution. Those are research possibilities, not evidence that such approaches are mainstream deployments today. The review is available through its NIST bibliographic record.
Public agencies and standards organizations are part of this evolving preparation. ENISA’s emerging technologies page covers AI and next-generation technology security and identifies recommendations for the frontier AI era in 2026. Organizations can use this kind of standards and guidance work to inform their plans while keeping forecasts separate from actions they can take now.
