HelloSign vs Certyneo Comparison: Which to Choose in 2026?

Introduction: why compare HelloSign and Certyneo in 2026?

With the progressive implementation of the eIDAS 2.0 regulation and the generalisation of hybrid working, the choice of an electronic signature solution has become a strategic issue for legal, HR and finance directors. HelloSign — rebranded as Dropbox Sign in 2023 but still widely known by its old name — and Certyneo position themselves in 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 from the angle 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 today 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) through 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 infrastructures — 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 focused on compliance

Certyneo is a B2B electronic signature SaaS designed and hosted in Europe, whose architecture was built from the outset around Regulation (EU) 2014/910 (eIDAS) and its evolution eIDAS 2.0. The platform offers the three signature levels 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 signature level appropriate for each document type. Hosting is carried out exclusively in ISO 27001 certified data centres located in the European Union, which considerably 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 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 dilutes traceability. However, certain legal acts — transfer of shares, electronic notarial deeds, certain credit contracts — require under French and European law a QES level or a notarial deed.

Furthermore, the question of data localisation is central: without robust binding corporate rules (BCR) or without properly documented standard contractual clauses (SCC), exposing signatory data to American servers may violate Articles 44 to 49 of the GDPR. A situation that has led several DPOs in Europe to exclude HelloSign from their calls for tender as early as 2024.

Certyneo and eIDAS: native compliance at three levels

Certyneo natively offers the three signature levels recognised by eIDAS, with automatic management of the required level depending 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 eIDAS 2.0 regulation: understanding everything introduces the European digital identity wallet (EUDIW), and Certyneo has committed to a roadmap of compatibility with this new standard as early as the first quarter of 2026. HelloSign has, to date, published no official roadmap in this regard for the European market.

3. Compared business features

Signature flows and automation

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

Certyneo stands out in particular with 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 a definite strength for teams already integrated into these ecosystems.

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

Signatory experience and mobility

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

4. Pricing and business model

HelloSign: a grid focused on signature volume

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

Certyneo: transparency and budget predictability

Certyneo adopts a per-user pricing model with included signature quotas, without billing per act for normal usage. You can view the full pricing schedule 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 offer to migrate to Certyneo includes technical and legal support, as well as the transfer of existing workflows — a commitment rarely offered by American players.

5. Support, accompaniment and ecosystem

Quality of French-language support

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

Certyneo has a support team based in France, reachable by chat, telephone and email, with contractual SLA commitments from intermediate plans onwards. The Certyneo help centre brings together over 200 articles in French covering 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 the HelloSign offering — is crucial for companies deploying electronic signature in sensitive contexts: mergers and acquisitions, litigation, healthcare or real estate sectors.

Legal framework applicable to electronic signature in 2026

Founding European texts

Electronic signature in Europe is governed by Regulation (EU) 2014/910 (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 to or logically associated with other data and used to sign.
• AES (Advanced Electronic Signature): uniquely linked to the signatory, enabling their identification, created with data under their exclusive control, and able to detect 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 registered on the European Trusted List. Only QES benefits from a legal presumption of equivalence to handwritten signature throughout the EU (Article 25(2) eIDAS).

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

GDPR and data localisation

Regulation (EU) 2016/679 (GDPR) 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 (Articles 44 to 49). Hosting this data on American servers, even under the 2023 Data Privacy Framework, exposes those responsible for processing to a residual risk documented by the European Data Protection Board (EDPB).

ETSI technical standards

Advanced and qualified electronic signature formats are standardised by ETSI: EN 319 132 (XAdES), EN 319 122 (CAdES) and EN 319 142 (PAdES for PDFs). These standards guarantee interoperability and the longevity of signatures over time. A solution that does not generate signatures in these standardised formats exposes its users to risks of non-recognition during audits or litigation.

Timestamping and retention

Qualified timestamping (Article 41 eIDAS) provides a legal presumption about the date and time of an electronic event. It is essential for the long-term probative value of signed documents. Probative electronic archiving, governed in France by the NF Z42-020 standard, complements this arrangement 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 the nullity of signed deeds, to evidentiary difficulties in the event of dispute and, in terms of data processing, to GDPR penalties that can reach 4% of annual global turnover (Article 83(5) GDPR).

Use cases: HelloSign vs Certyneo in real situations

Scenario 1: a corporate law firm with 20 collaborators

A law firm specialising in corporate law handles several dozen share transfers, shareholder agreements and settlement 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 blocker: for each document requiring this level, it was necessary to switch to a third-party provider, creating breaks in the traceability chain and additional delays of 24 to 48 hours. After migrating to Certyneo, the firm reduced by 65% the processing time for transfer cases, centralising 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 framework contracts, purchase orders and confidentiality agreements signed by suppliers spread across 12 European countries. The diversity of stakeholders — some of whom are unfamiliar with digital technologies — requires a simple signatory experience, available in multiple languages, without account creation.

HelloSign performed well on the "volume" dimension but presented shortcomings in French language localisation and configurable automatic reminders. With Certyneo, the procurement team configured distinct workflows by contract category, with signature levels adapted (SES for internal NDAs, AES for framework contracts) and automatic reminders at D+3 and D+7. The average time to return signed contracts fell 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 of approximately 1,200 beds

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

HelloSign, hosted on American infrastructure, was ruled out of scope from the outset under HDS regulations. Certyneo, whose healthcare offering is built on HDS-certified hosting in France, allowed the establishment 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 recruitment and practitioner engagement processes was assessed at the equivalent of 0.8 FTE administrative per year, representing a 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 European regulatory requirements for 2026. Certyneo, natively designed for the European market, meets the three eIDAS levels, guarantees hosting compliant with GDPR in the European Union and integrates advanced business features — AI contract generator, qualified timestamping, French-language support — that are lacking in its American competitor.

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