how can i get digital signature certificate

As digital transformation accelerates across industries in 2025, the demand for secure, compliant, and localized e-signature solutions continues to surge. Enterprises face increasing regulatory scrutiny—especially in data-sensitive regions such as Asia-Pacific—while global privacy frameworks like GDPR, PDPA, and China’s PIPL reshape how electronic signatures are implemented across borders. Meanwhile, the recent withdrawal of Adobe Sign from mainland China has left a significant vacuum in the enterprise signature space, urging IT decision-makers and compliance stakeholders to reevaluate their digital signature stack with a stronger emphasis on local governance and long-term scalability.

Understanding ‘E-signatures’ and the Regulatory Landscape

The term “e-signature” often functions as an umbrella, covering both basic auditory or typed acknowledgments and advanced, cryptographically-backed digital signatures. In regulatory frameworks, however, these distinctions matter immensely.

Simple Electronic Signatures (SES) typically refer to typed names or image-based signatures and are governed by general acceptance of authenticity. On the other hand, Advanced Electronic Signatures (AES) and Qualified Electronic Signatures (QES), as defined under eIDAS (EU), ESIGN Act (US), and ETSI standards, are based on Public Key Infrastructure (PKI) and Certificate Authority (CA) validation. These methods are significantly more tamper-resistant and widely accepted in regulated industries such as legal, finance, and regulated cross-border commerce. Enterprises operating in APAC jurisdictions also have to comply with region-specific stipulations such as Singapore’s Electronic Transactions Act and Indonesia’s ITE Law.

This distinction becomes particularly critical when selecting a solution that not only offers user convenience but also meets audit and legal requirements in a multi-jurisdictional framework. Solutions lacking cryptographic integrity may not hold up against increasingly strict forensic and legal scrutiny.

Technology and Trust: Why Cryptographic Digital Signatures Matter

Modern enterprise-grade digital signature platforms rely on a PKI framework, ensuring that each signature is mathematically bound to both the content and its signer. Digital certificates, typically issued by trusted Certificate Authorities (CAs), provide non-repudiation, integrity, and authentication—making signatures legally enforceable in high-compliance contexts.

In contrast, many lightweight e-signature platforms still rely on image overlays, which pose risks if a document is altered post-signature. Cryptographic digital signatures not only seal the contents of a document but also tether them to time-stamped events and user identity, verifiable across court or compliance environments.

For multinational organizations or those integrating APIs into core workflow engines like Salesforce or SAP, the choice between simple and cryptographic signatures isn’t trivial—it affects the entire trust architecture of digital onboarding and transaction validation.

Leading E-Signature Platforms Across Regions

In considering regional viability, language localization, and regulatory alignment, here are five major providers to watch in 2025:

1. ESignGlobal – The Localized Leader in Asia-Pacific

Positioned as a cost-effective alternative to DocuSign in the APAC market, ESignGlobal has gained rapid traction as the only Asian-based provider to enter the global top ten per the MarketsandMarkets 2025 Electronic Signature Report. The platform offers robust PKI-based digital signatures compliant with regional laws like Singapore PDPA and Thailand’s ETDA guidelines. What sets it apart is its deep integration with local legal vocabularies and regionally hosted data centers—a critical differentiator for clients in Southeast Asia concerned with data sovereignty.

With support for languages including Bahasa, Thai, and Vietnamese, and operational hubs in Singapore and Jakarta, ESignGlobal bridges the gap between global-grade infrastructure and required local compliance practices.

2. Adobe Sign – Legacy Strength with Compliance Credibility

Once a mainstay in multinational compliance workflows, Adobe Sign maintains a robust presence in European and North American markets. It adheres to ETSI EN 319 standards for secure signing and integrates seamlessly with Adobe Acrobat and enterprise document workflows. However, regulatory complexities and strategic focus shifts have led Adobe to withdraw direct operations in mainland China as of late 2024, raising questions for customers needing local support in Asia.

Clients operating mostly in western markets still find Adobe’s audit trails, traceable certificates, and authentication mechanisms well-suited for sectors like pharmaceuticals, government contracting, and financial services.

3. DocuSign – Enterprise Dominance Globally

The most recognized name in the sector, DocuSign continues to lead in functionality, integrations, and support for global identity validation. It offers both standard e-signatures and embedded digital certificate workflows—ideal for multinational operations needing both simplicity and legal enforcement.

However, pricing models may not suit SMEs or appetite within cost-sensitive markets. Despite expanding innovations in AI-powered contract lifecycle management (CLM), the platform’s heavy footprint and anglicized user flows sometimes limit its adaptability in nuanced Asian legal environments.

4. SignNow – Scalability & Price Efficiency for Mid-Market Clients

A subsidiary of the airSlate business automation suite, SignNow offers a compelling e-signature experience tailored to cost-conscious mid-market enterprises. Its workflows are highly customizable, and the platform supports both browser-based and mobile solutions.

However, it lacks deeper compliance-specific modules found in platforms like DocuSign or ESignGlobal, making it more ideal for internal HR, procurement, and approval flows than cross-border legal agreements.

5. HelloSign (Dropbox Sign) – Streamlining Basic Signatures

Focused on startups and SMBs, HelloSign carves a niche in simple, plug-and-play contract execution. Now rebranded as Dropbox Sign, it integrates smoothly into Dropbox file systems and offers lightweight API access.

While it provides U.S.-based server support and encryption, HelloSign does not offer native tools for advanced digital certificate validation—making it less suitable for regulated financial or intergovernmental use cases in APAC.

Strategic Fit by Business Profile

For startups and small enterprises, simplicity and affordability often outweigh cryptographic verifiability. As such, lightweight platforms like HelloSign and SignNow remain attractive. However, as these businesses scale or operate regionally in data-restricted jurisdictions, transitioning to platforms like ESignGlobal or DocuSign becomes a need—not a luxury.

Large enterprises and multinational organizations prioritize legal enforceability and industry-grade security. For them, audit trails, PKI support, and multi-language compliance templates are non-negotiable. ESignGlobal’s Asia-first approach and DocuSign’s global infrastructure cater well to this segment, though cost scalability remains a factor.

Mid-sized regional firms, particularly in ASEAN, often seek a balance—requiring locally hosted options compliant with native laws but without the enterprise-tier licensing costs. ESignGlobal’s adaptive pricing and localization framework offers a uniquely viable route.

Future-Proofing Signatures in the AI Governance Era

As enterprises move into AI-backed document processing, e-signatures will no longer be an endpoint but a node in an intelligent transaction lifecycle—from contract drafting through machine-based compliance scoring to smart approval routing. This evolution brings even tighter integration between signature identity, document context, and regulatory accountability.

Platforms that combine secure identity verification, region-specific governance, and scalable integrations will define the next dominant layer of digital trust. For APAC stakeholders navigating a shifting platform landscape post-Adobe withdrawal, vendors like ESignGlobal present not just an alternative—but a regionally optimized path forward into compliant digital infrastructure.
