HelloSign vs Certyneo Comparison: Which One to Choose in 2026?

Introduction: Why Compare HelloSign and Certyneo in 2026?

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

1. Overview 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 SMBs 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. Signatory data is hosted on American cloud infrastructure — a non-negligible constraint since the invalidation of Privacy Shield and the implementation of the Data Privacy Framework, which some legal experts still consider fragile.

Certyneo: A European SaaS Solution Centered on Compliance

Certyneo is a B2B electronic signature SaaS designed and hosted in Europe, with an architecture built from the ground up around eIDAS Regulation No. 910/2014 and its evolution eIDAS 2.0. The platform provides the three levels of signature provided for in the European framework — simple (SES), advanced (AES), and qualified (QES) — with qualified trust service providers (QTSP) listed 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 document type. Hosting is exclusively carried out in datacenters certified ISO 27001 located in the European Union, which significantly 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 trust chain and dilutes traceability. Yet certain legal acts — transfer of corporate shares, electronic notarized deeds, certain credit contracts — impose under French and European law a QES level or a notarial deed.

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

Certyneo and eIDAS: Native Three-Level Compliance

Certyneo natively provides the three levels of signature recognized by eIDAS, with automatic management of the required level based on the document type 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: Everything You Need to Know introduces, moreover, the European Digital Identity Wallet (EUDIW), and Certyneo has committed to a compatibility roadmap with this new standard starting in the first quarter of 2026. HelloSign has not yet published any 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 distinguishes itself notably through its AI-powered contract generator, which makes it possible to produce a legally structured document before submitting it for signature, without leaving the platform. HelloSign, refocused on its core business of "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 provides a documented REST API with OpenAPI 3.0, real-time webhooks, and certified connectors for major HRIS platforms (Workday, Lucca, Factorial) and ERP systems (SAP, Sage). For HR solutions, integration with employment contract management workflows, amendments, and dematerialized payslips is particularly advanced.

Signatory Experience and Mobility

Both platforms offer a signature experience without requiring account creation for the signatory. Certyneo, however, offers an interface entirely localized in French, with contextual guides explaining the legal value of each signature type — an asset appreciated when rolling out to populations unfamiliar with digital tools.

4. Pricing and Business Model

HelloSign: A Grid Centered on Signature Volume

HelloSign offers three pricing levels: Essentials (~$15/month/user), Standard (~$25/month/user), and Premium (on quote). Pricing is based on the number of submissions per month, which can become expensive for companies with high volumes of recurring documents. Note: advanced eIDAS compliance features are generally only available starting from Premium plans, with additional costs.

Certyneo: Transparency and Budget Predictability

Certyneo adopts a per-user pricing model with included signature envelopes, with no per-act billing for standard use. You can view the full 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, Certyneo's migration offer includes technical and legal support, as well as 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 obtaining precise answers on European compliance questions, as these topics are often redirected to general documentation.

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

Partner Ecosystem and Consulting

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

Legal Framework Applicable to Electronic Signature in 2026

Foundational European Texts

Electronic signature in Europe is governed by 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 affixed to or logically associated with other data, used for signing.
• AES (Advanced Electronic Signature): linked uniquely to the signatory, allowing their identification, created using 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).

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

GDPR and Data Localization

GDPR Regulation No. 2016/679 requires that personal data of signatories (identity, IP address, timestamp, certificate) be processed with a legal basis and, in case of transfer outside the EU, on the grounds 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 a residual risk documented by the European Data Protection Board (EDPB).

ETSI Technical Standards

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

Timestamping and Preservation

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

Legal Risks of a Non-Compliant Solution

Using an electronic signature solution that does not comply with eIDAS exposes the company to deed nullity, probative difficulties in case of dispute, and, regarding data processing, to GDPR penalties that may 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 manages several dozen share transfers, partnership agreements, and transaction protocols each month. These documents require at minimum 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 the processing time for transfer cases 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 SMB Managing 300 Supplier Contracts per Year

An SMB in the manufacturing sector with a procurement department of 5 people must have framework contracts, purchase orders, and confidentiality agreements signed by suppliers across 12 European countries. The diversity of stakeholders — some of whom are uncomfortable with digital tools — requires a simple signatory experience, available in multiple languages, without account creation.

HelloSign responded well to the "volume" dimension but showed gaps in French 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 reduction of 70%, consistent with benchmarks published by professional associations in the sector.

Scenario 3: A Hospital Group with Approximately 1,200 Beds

A public healthcare institution must digitize the signature of several types of documents: practitioner engagement contracts, clinical research protocols, conventions 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 perimeter. Certyneo, whose healthcare offering is built on HDS-certified hosting in France, allowed the institution to deploy electronic signature for all its HR and administrative processes in less than six weeks, with integrated user training and dedicated support. The estimated gain on practitioner recruitment and engagement processes was valued at the equivalent of 0.8 FTE administrative per year, achieving a positive ROI within four months 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 against the European regulatory requirements of 2026. Certyneo, designed natively for the European market, meets all three eIDAS levels, guarantees compliant EU hosting in accordance with GDPR, and integrates advanced business features — AI contract generator, qualified timestamping, French-language support — that its American competitor lacks.

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