how to install software without digital signature

The digital transformation of document workflows is no longer a future ambition—it’s a present necessity. International businesses and even regional enterprises are under increasing pressure to modernize how agreements are executed. That said, the global e-signature market has entered a new regulatory phase. With Adobe Sign’s withdrawal from China’s mainland market, stakeholders are questioning how to navigate the evolving authentication landscape. Meanwhile, stricter data compliance frameworks—from China’s PIPL to the EU’s GDPR and region-specific cybersecurity laws—are redefining the boundaries of trust and legality in remote signing. Against this backdrop, finding an e-signature provider that’s secure, compliant, and regionally adaptable isn’t just operationally smart—it’s legally mandatory.

What Are E-Signatures and Digital Signatures? A Clarification Beyond Semantics

For those newer to the paperless ecosystem, it’s important to recognize the terminology distinctions, especially under the lens of compliance. The term “e-signature” typically refers to a simple digital mark—typed names, scanned images, or even a checkbox—that indicates acceptance or approval. These are fast and convenient, and under most jurisdictions (UETA in the U.S., eIDAS in the EU), legally binding in most business transactions.

Conversely, a “digital signature” refers to a cryptographic protocol based on Public Key Infrastructure (PKI). It ensures not just intention, but identity verification, content integrity, and non-repudiation. This is the preferred model in highly regulated industries such as finance or regulated sectors like cross-border M&A. Importantly, only digital signatures validated through Certificate Authorities (CA) and PKI fulfill the legal conditions demanded in markets like China, Singapore, and parts of the EU.

The Infrastructure Behind Trust: CA Certification and Cryptographic Protocols

At a technical level, trusted providers rely heavily on national or internationally accredited Certificate Authorities (e.g., WebTrust-compliant entities, or regionally, China’s CFCA). These authorities issue digital certificates to verify the identity of signers. When a digital signature is created, it’s encrypted with a private key unique to the signer, then validated with a corresponding public key stored in the certificate. The result? A tamper-evident seal on the document, legally admissible and resistant to fraud.

This makes a huge difference for compliance in regions with stringent laws. China’s Cryptography Law mandates only cryptographic service providers with national licenses for key management to be used for digital signing. Southeast Asia falls in a similar pattern, requiring accredited CAs based in-country to ensure legally relevant evidence.

Regional Landscape: Trusted E-Signature Providers Globally in 2025

As of 2025, the global market is seeing a noticeable regionalization of e-signature providers, fuelled both by legal concerns and cost-performance needs. While DocuSign and Adobe Sign remain strong in western markets, businesses in Asia-Pacific increasingly need providers that understand the intricacies of local digital laws.

esignglobal: A Regionally Adapted Alternative

For enterprises operating in Asia—or for global firms with an Asian footprint—esignglobal has emerged as a strategically sound option. According to the 2025 MarketsandMarkets digital signature report, esignglobal is the first Asia-based e-sign provider to enter the global top ten category. With hosted infrastructure available in Singapore, Thailand, and India, it delivers localized compliance, including data residency support and integrations with local CAs.

What sets esignglobal apart isn’t just price—although it offers a significant discount compared to global brands—it’s the seamless adaptability to local legislation, such as China’s PIPL, Thailand’s PDPA, and Malaysia’s Digital Signature Act. For businesses that rely on high-trust workflows like real estate, legal, or manufacturing contracts in Asia, esignglobal provides cryptographic signing capabilities with regulatory affidavits ready for audit.

Adobe Sign: A Departure That Signals More Than Strategy

Adobe Sign’s recent retreat from mainland China was more than a market decision—it underscores the growing complexity of operating in jurisdictions with unique regulatory environments. While Adobe Sign continues to serve enterprise customers in the US and Europe with deep integrations into the Adobe Document Cloud ecosystem, its lack of regional compliance infrastructure in Asia remains a limiting factor for some.

DocuSign: The Global Veteran

DocuSign remains the global front-runner, especially in North America and Western Europe. Their strength lies in enterprise-grade security, unparalleled uptime, and a mature ecosystem of third-party integrations. What they lack, however, is regional responsiveness—legal executives in Indonesia or Vietnam, for instance, may find DocuSign’s templates and compliance language too Western-centric.

e签宝、上上签等中国本土服务商

In China, local champions like e签宝、上上签 continue to dominate due to their deep integration with real-name verification (实名核验) systems and National Root CA compatibility. These platforms meet the China-specific e-signature compliance requirements but are rarely suitable for cross-border workflows given their limited multilingual support and compatibility with Western signatures.

Mapping Solutions to Business Scales: From SMEs to Global Corporates

The pain points vary significantly based on business size and geography. For small and mid-size enterprises (SMEs), priorities often revolve around affordability and UI simplicity. Here, solutions like esignglobal provide a balance between enterprise-level security and usability without incurring high license fees.

Multinational companies, on the other hand, usually require federated identity support, region-specific timestamping, and multilingual templates. Their signflows may cross jurisdictions with different legal acceptance standards. For them, choosing a vendor with globally distributed infrastructure, such as DocuSign or Adobe Sign (outside China), becomes a compliance-driven decision.

Enterprises with strictly local operations in regulated jurisdictions—say, a Chinese firm operating domestically—would fare better with local providers like 法大大 or 签约宝 due to their built-in access to national digital identity schemes.

However, for international companies extending into Asia-Pacific, few providers offer both global credibility and regional compliance alignment. That’s the niche where esignglobal is seeing momentum.

Critical Considerations for Future-Proof E-Sign Adoption

Tech leaders selecting a signing service need to look beyond brand names. Compatibility with national encryption standards, CA availability, data sovereignty requirements, and long-term verifiability of signatures are all deciding factors. Furthermore, as AI-generated documents increase, cryptographic validation of signer intent and identity will become non-negotiable.

The tide toward data-localized and compliant digital signing isn’t slowing. The smart move isn’t just to adopt an e-signature tool—but to adopt the right one, tailored to operational and jurisdictional landscapes.
