Electronic signature trends 2025: comprehensive review

Electronic signature is undergoing a period of profound transformation. Between the progressive entry into force of the eIDAS 2.0 regulation, the integration of artificial intelligence into documentary workflows and the rise of biometric solutions, 2025 has laid the foundations for lasting market transformation. According to Marketsandmarkets, the global electronic signature market is expected to reach $35.3 billion by 2029, with a compound annual growth rate (CAGR) of 30.5%. For European B2B companies, understanding these developments is not optional: it is a condition for competitiveness and compliance. This article provides a structured review of the main trends that marked 2025 and anticipates developments that will emerge in 2026.

eIDAS 2.0: overhaul of the European digital trust framework

From Regulation 910/2014 to the revised framework: what's changing

Adopted in May 2024 and progressively implemented throughout 2025, Regulation eIDAS 2.0 (EU Regulation 2024/1183) represents the most significant revision of the European electronic identification framework since 2014. The most structural innovation is the mandatory introduction of the European Union Digital Identity Wallet (EUDIW), which each Member State must offer its citizens by 2026 at the latest.

This digital wallet will allow each user to store verified identity attributes (passport, diplomas, driving licence, tax data) and present them to sign documents with a high level of assurance. For electronic signature platforms, this means mandatory technical interoperability with national wallets via the technical specifications published by the EUDI Toolbox.

To explore the implications of this reform in depth, consult our comprehensive guide to eIDAS 2.0 regulation.

New assurance levels and practical impacts

eIDAS 2.0 maintains the SES (Simple), SEA (Advanced) and SQS (Qualified) trilogy, but strengthens audit and interoperability requirements for Qualified Trust Service Providers (QTSP). In 2025, several Member States — including France, Germany and the Netherlands — finalised their updated national trust lists in accordance with the new ETSI TS 119 612 requirements.

In practical terms, companies using qualified signatures for public procurement, dematerialised notarial deeds or financial contracts must now verify the compatibility of their service providers with the new technical specifications. The French trust list published by ANSSI is the national reference in this regard.

Artificial intelligence: from fraud detection to contract generation

AI in support of identity verification

The integration of artificial intelligence models into Know Your Customer (KYC) and remote identity verification (IDV) processes emerged as the dominant technology trend of 2025. Liveness detection solutions — capable of distinguishing a real face from a photo or deepfake — have reached accuracy levels exceeding 99.7% according to benchmarks published by the NIST (National Institute of Standards and Technology) in its 2024 FRVT report.

For advanced electronic signatures requiring strong authentication, this evolution is determining. Service providers who integrate proprietary Computer Vision models or specialised APIs (such as iBeta Level 2 certified) now offer signature workflows that combine:

• Passive facial recognition (passive liveness)

• Real-time behavioural analysis

• Cross-verification with identity document data (OCR + NFC chip reading)

Workflow automation and document generation

Generative AI, whose adoption in the enterprise exploded between 2023 and 2025, is also transforming the upstream phase of signature: document creation and verification. Tools such as our AI contract generator now make it possible to produce legally structured documents in minutes, reducing drafting errors and accelerating commercial closing cycles.

According to a 2024 McKinsey study, automation of documentary processes allows legal and commercial teams to reduce time spent on contract preparation by 40% to 60%. In 2025, this trend accelerated with the emergence of end-to-end pipelines: AI generation → assisted review → automatic routing → electronic signature → timestamped archiving.

Advanced biometrics: the new standard for strong authentication

Behavioural biometrics and digitised handwritten signature

Biometrics is no longer limited to facial recognition or fingerprints. In 2025, behavioural biometrics — which analyses how a user types on a keyboard, moves their mouse or performs a touch gesture — has emerged as a complementary authentication factor particularly suited to advanced electronic signatures.

Digitised handwritten signature (Handwritten Electronic Signature), which captures the dynamics of the gesture (pressure, speed, acceleration, stylus angle), is now recognised by several European courts as solid evidence material, provided it is associated with qualified timestamping and a non-repudiation mechanism.

Multi-factor Authentication (MFA) and FIDO2

The FIDO2/WebAuthn protocol, promoted by the FIDO Alliance and integrated into major browsers, became the de facto standard in 2025 for strong passwordless authentication in signature workflows. Its native compatibility with eIDAS 2.0 and EUDIWs makes it an essential technical pivot for SaaS signature platforms.

Companies that have not yet migrated to robust MFA authentication face increasing risks of identity spoofing during signature processes, with direct implications for the evidential value of their documents. Our comparison of electronic signature solutions incorporates this criterion as an indicator of security maturity.

Sectoral adoption and market maturity in 2025

Fast-growing sectors: HR, real estate and healthcare

Three sectors concentrated the majority of electronic signature adoption growth in 2025 in France:

Human Resources: the dematerialisation of employment contracts, amendments, DPAE documents and payslips accelerated following publication of CNIL recommendations on signing HR documents (ruling of 14 March 2024). The adoption of electronic signature for HR teams reduces average onboarding time by 70% according to sector benchmarks.

Real Estate: electronically signed promises to sell, mandates and commercial leases represented more than 65% of non-notarial real estate deeds in France in 2025, according to FNAIM data. Electronic signature in real estate is now operational standard, not innovation.

Healthcare: interoperability with hospital information systems (HIS) and GDPR requirements for health data (special category, article 9) have led to the emergence of HDS-certified solutions (Health Data Hosting). Our dedicated page on electronic signature in the healthcare sector details specific technical and regulatory requirements.

Market consolidation and platform migrations

2025 was also marked by notable consolidation of the European electronic signature market. Several historic players were acquired or merged, whilst more agile SaaS platforms captured significant market share thanks to their responsiveness to new eIDAS 2.0 requirements and competitive pricing.

Many companies initiated migration processes in 2025 from legacy solutions to more modern platforms. If you are considering this type of transition, our guide on migration from DocuSign or YouSign to Certyneo offers a practical roadmap.

Applicable legal framework for electronic signature in 2025-2026

The legal value of an electronic signature rests on a precise regulatory stack that any organisation must master to secure its contractual commitments.

French Civil Code — Articles 1366 and 1367 Article 1366 of the Civil Code establishes the principle of equivalence: "Electronic writing has the same probative force as writing on paper, provided that the person from whom it emanates can be duly identified and that it is established and preserved in conditions such as to guarantee its integrity." Article 1367 specifies that electronic signature "consists in the use of a reliable identification process guaranteeing its link with the document to which it is attached".

Regulation eIDAS No. 910/2014 and its revision eIDAS 2.0 (EU Regulation 2024/1183) This regulation establishes the unified European legal framework for electronic trust services. It distinguishes three signature levels: simple (SES), advanced (SEA) and qualified (SQS). Only qualified signature benefits from a legal presumption of equivalence to handwritten signature in all Member States (article 25, §2). eIDAS 2.0 strengthens interoperability via EUDIW and extends the scope of trust services.

GDPR No. 2016/679 Electronic signature processes involve processing of personal data (identity, biometrics, behaviour) that fall under GDPR. Organisations must have a valid legal basis (article 6), conduct an impact assessment (DPIA — article 35) when biometric data is processed, and document their processing register (article 30). Biometric data constitutes a special category (article 9) requiring explicit consent or another exemption provided by the regulation.

ETSI Standards The ETSI EN 319 132-1 standard defines advanced electronic signature formats XAdES, PAdES and CAdES. ETSI EN 319 401 sets general requirements for Trust Service Providers. Compliance with these standards conditions cross-border interoperability of signatures within the EU.

NIS2 Directive (EU 2022/2555) Transposed into French law by Law No. 2024-449 of 21 May 2024, the NIS2 Directive imposes enhanced cybersecurity obligations on essential service operators and important entities. SaaS electronic signature platforms serving critical sectors (healthcare, finance, energy) may be subject to incident notification obligations and supply chain risk management.

Legal risks in case of non-compliance An electronic signature not meeting the requirements of its declared level can be challenged in court, resulting in contract nullity or non-enforceability. GDPR sanctions can reach 4% of annual global turnover. Under NIS2, administrative fines can reach €10 million for essential entities.

Use scenarios: electronic signature and 2025 innovations

Scenario 1 — A law firm of 15 lawyers generalising qualified signature

A legal practice of fifteen lawyers specialising in business law, managing several hundred deeds per year (sale of business funds, shareholders' agreements, service agreements), faced two recurring problems in 2024: signing delays extended 5 to 10 days per deed due to paper circuits, and growing difficulty proving the identity of remote signatories in case of dispute.

By migrating to a qualified electronic signature solution compatible with eIDAS 2.0 with integrated biometric verification (liveness detection ISO 30107-3 Level 2), the firm reduced its average signing time to less than 48 hours whilst having a complete audit trail (authentication log, qualified timestamp, signature certificate). According to benchmarks from the legal sector published by the National Bar Council in 2024, firms that have dematerialised their signature processes observe a reduction of 55% to 70% in administrative time spent on deeds.

Scenario 2 — An SME automating supplier contracts with AI

An SME in the industrial sector managing approximately 300 supplier contracts per year (NDAs, framework purchase agreements, price amendments) integrated an AI-to-signature documentary pipeline in 2025. Automatic contract generation from parametrised templates, combined with intelligent routing to internal and external signatories, reduced the average contractualisation cycle from 18 days to less than 4 days.

Native integration with their ERP via REST API also eliminated double data entry and contractual data errors. Productivity gains are estimated to represent 0.8 FTE (full-time equivalent) reassigned to higher value-added tasks. This type of ROI is consistent with ranges published by Aberdeen Group in its 2024 report on procurement automation.

Scenario 3 — A hospital group securing patient consent

A hospital group of approximately 600 beds had to manage hundreds of informed consent forms daily for surgical procedures and clinical research protocols. Paper management generated document loss, delays incompatible with medical urgency and GDPR non-compliance risks (health data, special category article 9).

By deploying an electronic signature solution hosted in an HDS environment (certified under the ANS/ASIP Santé reference), the group was able to collect consent on tablet at the patient's bedside with authentication via mobile OTP. Documents are automatically filed in the EHR (Electronic Health Record) with qualified timestamp. The rate of incomplete or illegible forms fell from 12% to less than 1%, and traceability now complies with CNIL requirements for health data.

Conclusion

2025 was the year of maturity for electronic signature in Europe: eIDAS 2.0 set a new interoperability standard, AI revolutionised document creation and verification, and advanced biometrics elevated confidence in signer authentication. These trends are not passing fads — they respond to increasing regulatory obligations and operational efficiency imperatives documented by sector data.

For B2B companies, the challenge for 2026 is clear: adopt a platform capable of absorbing these innovations without multiplying complex integrations or undermining legal compliance. Certyneo natively integrates these developments in a solution designed for business teams and legal departments.
