Security researchers have increasingly warned us that threat actors are currently looking to harvest encrypted data from enterprises with full knowledge that quantum systems will eventually be able to decrypt the data.

The shift from theoretical to practical considerations is changing the manner in which CISOs evaluate long-term cyber resilience.

Gartner estimates that global spending on cybersecurity will amount to an estimated $213 billion by 2025 due to enterprises’ increased investment in cloud security, AI governance, cyber resilience, and quantum-readiness initiatives.¹

In addition, by 2027, most enterprises will be under heightened pressure to implement quantum-resistant cryptographic frameworks.

IBM estimates that large-scale enterprise cryptographic migration programs could require between 5–8 years due to legacy infrastructure complexity and operational dependencies.²

The World Economic Forum warns that cryptographically relevant quantum systems capable of threatening current encryption standards could emerge by 2036

That overlap between migration timelines and future decryption risk is rapidly becoming one of the most important cybersecurity discussions in enterprise boardrooms. 

The Quantum Economy by the Numbers

Enterprise Indicator	Current Estimate
Global cybersecurity spending (2025)	$213B
Global quantum technology market (2025)	$1.9B
Government quantum funding commitments	$12.7B
Forecast the PQC market value by 2034	$6.97B
PQC market CAGR	37.1%
Organizations lacking quantum readiness	90%

Why 2026 Is Becoming the “Y2Q” Preparation Year

Many people think that businesses will have ample time to prepare for post-quantum cryptography (PQC). The truth is that the preparation timeline has already begun.

The greatest immediate risk is not that quantum systems will suddenly break encryption tomorrow morning.

The larger concern is that encrypted enterprise data stolen today could remain valuable for decades.

This includes:

• Financial records
• Healthcare archives
• Defense contracts
• Enterprise authentication data
• Intellectual property
• Government communications

This evolving threat model is widely known as: “Harvest Now, Decrypt Later”

Threat actors collect encrypted data today.

They store it for long-term exploitation.

They wait for future quantum systems capable of breaking RSA and ECC-based encryption standards.

Deloitte warns that cryptography is deeply embedded across enterprise infrastructure, making future migration significantly more complex than most organizations currently estimate.³

Market Momentum Is Accelerating Faster Than Expected

The enterprise quantum market is no longer driven by experimentation alone.

Investment activity is accelerating globally.

There is a rush for investment in this area worldwide, with global spend toward quantum technologies projected to reach $1.9B by 2025.⁴

The number of government-funded quantum initiatives has also surpassed $12.7B worldwide⁵, with the broader quantum market expected to reach nearly $100B within 10 years, driven by the faster adoption rates of enterprises.⁶

The message to leaders of enterprises is increasingly clear:

Quantum readiness is transitioning from innovation strategy to operational resilience planning.

NIST Has Shifted the Industry From Awareness to Execution

NIST’s standardization of ML-KEM and ML-DSA has transformed enterprise conversations around PQC migration.

The organization officially finalized FIPS 203, FIPS 204, and FIPS 205 standards to support post-quantum cryptographic implementation.⁷

Security leaders are no longer asking:

“Should we prepare for post-quantum cryptography?”

They are now asking:

“How quickly can we realistically migrate without operational disruption?”

That difference matters.

Google and AWS Are Expanding Hybrid Cryptography Initiatives

Google continues expanding hybrid cryptography initiatives across Chrome, TLS infrastructure, and enterprise connectivity environments.

AWS has also expanded support for hybrid quantum-safe key exchange capabilities across cloud workloads.

The significance goes beyond technology implementation.

The world’s largest infrastructure providers are actively preparing for a long-term cryptographic transition.

Enterprise boards are noticing.

Black Hat 2025 Revealed a Serious Enterprise Weakness

One of the strongest recurring themes across Black Hat USA and DEF CON 2025 was surprisingly straightforward:

Most enterprises still do not know where all of their cryptography exists.

That creates a major visibility challenge.

Security teams cannot modernize cryptographic infrastructure that they cannot identify.

Deloitte increasingly recommends cryptographic inventory and crypto-agility assessments as foundational requirements for enterprise quantum readiness.

Why Hybrid Cryptography Is Emerging as the Enterprise Default

Most enterprises are not deploying pure post-quantum cryptography yet.

Instead, hybrid cryptographic models are becoming the preferred transition strategy.

Examples include:

• ECC + ML-KEM hybrid key exchange
• Classical signatures + ML-DSA validation

This approach helps organizations:

• Reduce operational disruption
• Improve interoperability testing
• Validate infrastructure compatibility
• Modernize gradually rather than aggressively

IDC forecasts hybrid cryptography deployments will dominate enterprise environments through at least 2028.

The Infrastructure Cost Challenge

Through 2025, the global market for post-quantum cryptography is projected to be valued at $308.6M, increasing to $6.97B by 2034, or 37.1% compound annual growth rate (CAGR). Accenture also states that creating crypto-agility involves the coordinated transformation of infrastructure components such as identity, applications, cloud platforms, and operational environments. ^8:9

Sector Readiness Snapshot

Industry Sector	PQC Readiness Level
Financial Services	High
Defense & Government	High
Healthcare	Medium–High
Manufacturing	Medium
Retail	Medium–Low
Small Enterprise	Low

Forecasts through 2027:

Prediction 1

Crypto-agility will become one of the KPIs used by boards of directors.

Gartner predicts that boards will increasingly treat crypto-agility as a resilience metric.

Prediction 2

The use of hybrid cryptography will become the standard for enterprises.

The use of both classical and quantum resistance algorithms through hybrid deployments is expected to continue at least through 2028.

Prediction 3

Regulatory Pressure Accelerates Faster Than Quantum Hardware

Forrester expects regulatory mandates and procurement requirements to become major enterprise adoption drivers over the next several years.

Executive Action Plan for CISOs

Immediate Priorities for 2026

1. Conduct a Cryptographic Inventory

Map RSA and ECC dependencies across enterprise infrastructure.

2. Prioritize Long-Retention Sensitive Data

Focus migration planning around highly sensitive long-term datasets.

3. Launch Hybrid Cryptography Pilots

Begin controlled ML-KEM and ML-DSA interoperability testing.

4. Pressure Vendors on PQC Readiness

Require suppliers and SaaS vendors to disclose quantum-readiness strategies.

5. Align PQC With Existing Modernization Programs

Integrate quantum-safe planning into:

• Zero-trust initiatives
• IAM modernization
• Cloud transformation
• Cyber resilience programs

Final Intelligence Takeaway

The most important quantum security development of 2026 is not the arrival of cryptographically relevant quantum systems.

It is the realization that enterprise migration timelines are already colliding with the future threat horizon.

The organizations moving fastest today are not necessarily the ones expecting immediate disruption tomorrow.

They are the organizations recognizing that waiting may ultimately become the biggest security risk of all.
