HelloSign vs Certyneo Comparison: Which to Choose in 2026?

Introduction: Why compare HelloSign and Certyneo in 2026?

With the progressive entry into force of the eIDAS 2.0 regulation and the generalization of hybrid work, the choice of an electronic signature solution has become a strategic issue for legal, HR and finance departments. HelloSign — rebranded as Dropbox Sign in 2023 but still widely known by its old name — and Certyneo position themselves on this market with very different philosophies. On one side, an American platform integrated into the Dropbox ecosystem; on the other, a European SaaS solution born to meet the regulatory requirements of the continental market. This article breaks down both offerings in terms of legal compliance, business features, pricing and user experience, to help you make an informed decision for 2026.

1. Presentation of the two platforms

HelloSign (Dropbox Sign): An American origin

Founded in 2011 and acquired by Dropbox in 2019, HelloSign is now marketed under the Dropbox Sign brand. The solution is very popular in Anglo-Saxon SMEs thanks to its ease of use and native integration with Dropbox, Google Workspace and Slack. It offers simple electronic signatures (SES) and, since 2022, an advanced form (AES) via third-party partners for certain European markets.

However, HelloSign remains a platform designed according to American standards (ESIGN Act, UETA), which creates regulatory friction for companies subject to European law. The data of signatories is hosted on American cloud infrastructures — a non-negligible constraint since the invalidation of Privacy Shield and the implementation of the Data Privacy Framework, which some lawyers still consider fragile.

Certyneo: A European SaaS solution focused on compliance

Certyneo is a B2B electronic signature SaaS designed and hosted in Europe, whose architecture is built from the outset around the eIDAS regulation No. 910/2014 and its eIDAS 2.0 evolution. The platform offers the three levels of signature provided for by the European framework — simple (SES), advanced (AES) and qualified (QES) — with qualified trust service providers (QTSP) referenced on the European Trusted List.

The solution natively integrates a comprehensive guide on the legal value of electronic signature that legal teams can consult to calibrate the appropriate signature level for each type of document. Hosting is exclusively carried out in ISO 27001 certified data centers located in the European Union, which greatly simplifies GDPR compliance.

2. Regulatory compliance and legal value

HelloSign facing European law: Structural gaps

The main weakness of HelloSign for European use lies in its relationship with eIDAS. The platform does not offer a qualified signature (QES) in its own right: to reach this level, the user must resort to hybrid workflows with third-party providers, which complicates the chain of trust and blurs traceability. However, certain legal acts — transfer of corporate shares, electronic authentic deeds, certain credit contracts — require by French and European law either a QES level or a notarial deed.

Furthermore, the question of data localization is central: without robust binding corporate rules (BCR) or perfectly documented standard contractual clauses (SCC), exposing signatory data to American servers may violate articles 44 to 49 of the GDPR. A situation that led several European DPOs to exclude HelloSign from their call for tenders as early as 2024.

Certyneo and eIDAS: Native compliance at three levels

Certyneo natively offers the three levels of signature recognized by eIDAS, with automatic management of the required level depending on the type of document configured by the administrator. This approach reduces the risk of human error — signing a commercial lease with a simple SES when an AES is recommended — and simplifies the audit trail for compliance teams.

The regulation eIDAS 2.0: Understanding everything introduces the European digital identity wallet (EUDIW), and Certyneo has committed to a roadmap for compatibility with this new standard from the first quarter of 2026. HelloSign has, to date, published no official roadmap in this regard for the European market.

3. Business features compared

Signature flows and automation

| Criterion | HelloSign (Dropbox Sign) | Certyneo | |---|---|---|| | Simple signature (SES) | ✅ | ✅ | | Advanced signature (AES) | ⚠️ Via third party | ✅ Native | | Qualified signature (QES) | ❌ | ✅ Native | | EU hosting | ❌ | ✅ | | REST API | ✅ | ✅ | | AI contract generator | ❌ | ✅ | | Qualified timestamping | ⚠️ Limited | ✅ | | French language support | ⚠️ Limited | ✅ |

Certyneo stands out in particular for its AI contract generator, which allows you to produce a legally structured document before submitting it for signature, without leaving the platform. HelloSign, refocused on its core business "signature", does not offer an equivalent.

Integrations and API

HelloSign has a mature API and native integrations with Salesforce, Google Workspace, Microsoft 365 and Dropbox. This is an undeniable strength for teams already integrated into these ecosystems.

Certyneo offers a REST API documented with OpenAPI 3.0, real-time webhooks and certified connectors for the main HCM systems (Workday, Lucca, Factorial) and ERP (SAP, Sage). For HR solutions, integration with employment contract management workflows, amendments and digitized payslips is particularly advanced.

Signatory experience and mobility

Both platforms offer a signature experience without account creation for the signatory. Certyneo, however, offers a fully localized interface in French, with contextual guides explaining the legal value of each type of signature — an advantage appreciated when deploying to populations unfamiliar with digital technology.

4. Pricing and economic model

HelloSign: A grid centered on signature volume

HelloSign offers three price tiers: Essentials (~€15/month/user), Standard (~€25/month/user) and Premium (on request). Pricing is based on the number of sends per month, which can become expensive for companies with high volumes of recurring documents. Note: Advanced eIDAS compliance features are generally only available from Premium plans, with additional costs.

Certyneo: Transparency and budget predictability

Certyneo adopts a per-user pricing model with included signature envelopes, without per-act billing for standard uses. You can view the complete pricing grid on the Certyneo pricing page and simulate your return on investment via the ROI calculator available online.

For companies wishing to migrate from another solution, the Certyneo migration offer includes technical and legal support, as well as the migration of existing workflows — a commitment rarely offered by American players.

5. Support, assistance and ecosystem

Quality of French-speaking support

HelloSign offers support in English with variable response times depending on the plan subscribed. In practice, French-speaking users report difficulties in obtaining accurate answers to questions about European compliance, these topics often being referred to general documentation.

Certyneo has a support team based in France, reachable by chat, phone and email, with contractual SLA commitments from intermediate plans onwards. The Certyneo help center brings together over 200 articles in French covering business use cases, regulatory aspects and technical integrations.

Partner ecosystem and consulting

Certyneo collaborates with a network of integrator partners, law firms and accountants trained in eIDAS compliance. This consulting dimension — absent from HelloSign's offering — is decisive for companies deploying electronic signature in sensitive contexts: mergers and acquisitions, litigation, healthcare or real estate sectors.

Legal framework applicable to electronic signatures in 2026

Foundational European texts

Electronic signature in Europe is governed by the eIDAS Regulation No. 910/2014 (Electronic IDentification, Authentication and trust Services), directly applicable in all Member States without national transposition. This regulation defines three levels of signature:

• SES (Simple Electronic Signature): any data in electronic form attached or logically associated with other data, used to sign.
• AES (Advanced Electronic Signature): linked unambiguously to the signatory, allowing their identification, created with data under their exclusive control, and detecting any subsequent modification.
• QES (Qualified Electronic Signature): AES created using a qualified signature creation device (QSCD) and based on a qualified certificate issued by a QTSP listed on the European Trusted List. Only QES benefits from a legal presumption of equivalence to handwritten signature throughout the EU (art. 25§2 eIDAS).

In French law, articles 1366 and 1367 of the Civil Code recognize electronic signature as equivalent to handwritten signature insofar as it allows identification of the signatory and guarantees its link with the deed. Decree No. 2017-1416 specifies the applicable technical conditions.

GDPR and data localization

The GDPR Regulation No. 2016/679 requires that personal data of signatories (identity, IP address, timestamp, certificate) be processed with a legal basis and, in the event of transfer outside the EU, on the basis of an adequacy decision or appropriate safeguards (art. 44 to 49). Hosting this data on American servers, even within the framework of the 2023 Data Privacy Framework, exposes data controllers to residual risk documented by the European Data Protection Board (EDPB).

ETSI technical standards

Electronic signature formats are standardized by ETSI: EN 319 132 (XAdES), EN 319 122 (CAdES) and EN 319 142 (PAdES for PDFs). These standards ensure interoperability and long-term signature preservation. A solution that does not generate signatures in these standardized formats exposes its users to risks of non-recognition during audits or disputes.

Timestamping and preservation

Qualified timestamping (art. 41 eIDAS) provides legal presumption as to the date and time of an electronic event. It is essential for the long-term probative value of signed documents. Evidence-based electronic archiving, governed in France by standard NF Z42-020, complements this system for regulatory retention periods (10 years for commercial contracts, 5 years for accounting data, 50 years for certain civil status deeds).

Legal risks of a non-compliant solution

Using an electronic signature solution that does not comply with eIDAS exposes the company to nullification of signed deeds, difficulty with evidence in the event of dispute and, in terms of data processing, to GDPR penalties that can reach 4% of annual global turnover (art. 83§5 GDPR).

Use cases: HelloSign vs Certyneo in real situations

Scenario 1: A corporate law firm with 20 collaborators

A law firm specializing in corporate law handles several dozen share transfers, shareholder agreements and settlement protocols each month. These documents require at least an advanced electronic signature (AES) to be enforceable, and often a QES for the most sensitive deeds.

With HelloSign, the legal team quickly identified the absence of native QES as a blocking issue: for each document requiring this level, they had to switch to a third-party provider, generating breaks in the traceability chain and additional delays of 24 to 48 hours. After migration to Certyneo, the firm reduced document processing time by 65%, by centralizing the entire workflow — document generation, signature level selection, sending, automatic follow-up, archiving — in a single interface.

Scenario 2: An industrial SME managing 300 supplier contracts per year

An SME in the manufacturing sector with a procurement department of 5 people must have supplier contracts, purchase orders and confidentiality agreements signed by suppliers spread across 12 European countries. The diversity of interlocutors — including some uncomfortable with digital technology — requires simple signatory experience, available in multiple languages, without account creation.

HelloSign responded well to the "volume" dimension but had gaps in French language localization and customizable automatic follow-ups. With Certyneo, the procurement team configured distinct workflows by contract category, with appropriate signature levels (SES for internal NDAs, AES for framework contracts) and automatic follow-ups at D+3 and D+7. The average return time for signed contracts dropped from 8.2 days to 2.4 days, a 70% reduction, consistent with benchmarks published by professional associations in the sector.

Scenario 3: A hospital group of approximately 1,200 beds

A public health establishment must dematerialize the signature of several types of documents: practitioner engagement contracts, clinical research protocols, agreements with institutional partners. The regulatory framework of the healthcare sector requires enhanced traceability and hosting of health data compliant with HDS requirements (Health Data Hosting, ASIP Santé certification).

HelloSign, hosted on American infrastructure, was immediately excluded from the HDS regulatory scope. Certyneo, whose healthcare offering is built on HDS-certified hosting in France, allowed the establishment to deploy electronic signature for all HR and administrative processes in less than six weeks, with integrated user training and dedicated support. The estimated gain on recruitment and practitioner engagement processes was valued at the equivalent of 0.8 administrative FTE per year, achieving positive ROI from the fourth month of use.

Conclusion

The HelloSign vs Certyneo comparison reveals two opposing philosophies: HelloSign is a generalist American solution, effective for simple use cases in English-speaking environments, but structurally limited in the face of 2026 European regulatory requirements. Certyneo, designed natively for the European market, meets the three eIDAS levels, guarantees GDPR-compliant hosting in the European Union and integrates advanced business features — AI contract generator, qualified timestamping, French-language support — that are missing from its American competitor.

For companies subject to French and European law, the choice is clear: regulatory compliance is not improvised, and every document signed with an inadequate solution is a latent legal risk.
