Key findings
Twelve findings carry the cybersecurity and cryptography baseline. They are grouped by coupling and never ranked. Each resolves to its source or, where Nexus analysis is involved, to its stated method.

2.1Headline finding
ReportedEQL 5NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-CRY-001
NIST finalised three post-quantum cryptography standards on 13 August 2024: FIPS 203 (ML-KEM), FIPS 204 (ML-DSA) and FIPS 205 (SLH-DSA).
| Item | Bar, scaled to the largest value | Value |
|---|---|---|
| FIPS 203 · key establishment (ML-KEM) | 1 | |
| FIPS 204 · signatures (ML-DSA) | 1 | |
| FIPS 205 · backup signatures (SLH-DSA) | 1 |
Source: NIST publication pages for FIPS 203, 204 and 205123. Each bar counts one standard.
Implication
Standards exist, so migration is now an engineering and planning task. NIST added HQC as a backup key-encapsulation method on a different mathematical basis, with a final standard expected in 20276. Guidance on using key encapsulation was published in September 20257. The NIST transition draft IR 8547, published on 12 November 2024, proposes disallowing quantum-vulnerable public-key algorithms after 203544.
What would move it
The HQC draft, sector migration progress and national directives would each move this finding.
2.2CRY
ReportedEQL 5NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-CRY-001
NIST finalised FIPS 203 (ML-KEM), FIPS 204 (ML-DSA) and FIPS 205 (SLH-DSA) on 13 August 2024. ML-KEM has three parameter sets: 512, 768 and 1024.123
ReportedEQL 4NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-CRY-002
NIST selected HQC on 11 March 2025 as a backup key-encapsulation method based on codes rather than lattices, with a draft standard expected in about a year and a final standard in 2027.632
ReportedEQL 4NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-CRY-007
A 2025 preprint estimates that RSA-2048 could be factored with fewer than one million noisy qubits in under a week, assuming a 0.1% gate error and a 1 microsecond cycle. The author’s 2019 estimate was about 20 million qubits in 8 hours.2237
2.3Governance
ReportedEQL 4NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-GOV-003
NIST published the initial public draft of the transition report IR 8547 on 12 November 2024. The draft proposes that quantum-vulnerable public-key algorithms at 112 bits of security be deprecated after 2030 and that all such algorithms be disallowed after 2035.44
ReportedEQL 4NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-GOV-004
The UK NCSC published migration timelines on 20 March 2025: assess and plan by 2028, do priority migration by 2031 and finish by 2035.10
2.4Infrastructure
ReportedEQL 2NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-INF-005
Cloudflare reported that most human traffic to its network used post-quantum key agreement in late October 2025, while 3.7% of origin servers supported it and an ML-DSA-44 signature adds about 15 kB to a TLS handshake. This is vendor evidence.23
ReportedEQL 3NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-INF-006
OpenSSH made a post-quantum key exchange its default in version 9.0 and switched the default to mlkem768x25519 in version 10.0. Version 10.1 warns when a connection does not use one.24
2.5THR
ReportedEQL 3NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-THR-008
The CISA KEV count at the 30 September close is not bound. A 3 November read of the catalogue is post-close, context only. A 2025 joint advisory from 23 agencies in 13 countries reported router compromise through known vulnerabilities and no observed zero-day exploitation. A vendor report states that 31% of breaches began with exploited vulnerabilities.1417
ReportedEQL 4NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-THR-009
The FBI received 859,532 complaints and USD 16.6 billion of reported losses in 2024, up 33% from 2023. It received 3,156 ransomware complaints and called ransomware the most pervasive threat to critical infrastructure.15
2.6Finance
ReportedEQL 2NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-FIN-010
Chainalysis estimates that ransomware actors received more than USD 820 million on-chain in 2025, about 8% below an updated USD 892 million for 2024. IBM puts the global average cost of a data breach at USD 4.99 million in 2026. Both are vendor estimates.1819
2.7SKL
ReportedEQL 3NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-SKL-011
In the ISC2 2025 study, 59% of respondents reported critical or significant skills needs, up from 44% in 2024. ISC2 published no workforce gap estimate in 2025.20
2.8Systemic
Expert inputEQL 2NRF-XTECH-CRYPTO-GLOBAL-2026-BASELINE-SYS-012
The leading compound pathway for 2027 testing is the lag of signatures, certificates and long-life devices behind key agreement, while exploited ordinary vulnerabilities keep dominating incidents. § scenario
