2025 Guide to Indonesia’s Leading Digital Signature Solutions

As digital transformation accelerates across Asia, the importance of legally compliant and efficient e-signature solutions continues to grow. Enterprises—both large and small—face increasing pressure to streamline contract workflows while adhering to complex regional regulations. In countries such as Indonesia, Vietnam, Malaysia, and the Philippines, legislation such as the ET Act (E-Commerce Law No.20/2023/QH15) and Decree No.130/2018/ND-CP have established a robust legal foundation for digital signatures. This shift in the regulatory and operational landscape has compelled organizations to revisit how they manage remote contract execution, onboarding processes, and B2B agreements in a secure, scalable, and legally sound manner.

Understanding E-Signatures and Local Legal Foundations

An electronic signature refers to any electronic method that indicates a person’s intention to approve the contents of a document—typically through clicks, digital stamps, or biometric identifiers. However, when referring to legally binding digital transactions, especially in Southeast Asia, one must distinguish between basic e-signatures and digital signatures. The latter relies on Public Key Infrastructure (PKI), Certification Authorities (CAs), and encrypted hash algorithms to ensure identity authentication and document integrity.

Vietnam’s E-Commerce Law (ET Act No.20/2023/QH15) and Decree No.130/2018/ND-CP mirror globally aligned frameworks by mandating that certain documents must be signed using recognized digital signatures issued by licensed CAs. This compliance requirement ensures documents are admissible in court, thereby mitigating risks in sectors such as banking, healthcare, and government procurement.

Asian E-Signature Market Landscape in 2025

The Asian e-signature market is seeing continued growth driven by digital transformation mandates and government-led initiatives. According to MarketsandMarkets, the global market for digital signatures is projected to reach $25.2 billion by 2025, with Asia-Pacific experiencing the fastest CAGR of 23.1%. Countries like Indonesia and Vietnam are prioritizing infrastructure development for cloud-based signature services, while mid-sized businesses increasingly seek local providers who understand regional compliance models and offer support in native languages.

Notably, 2025 marks the first year an Asia-born e-signature vendor, eSignGlobal, has entered the top 10 global providers, underscoring a unique shift: enterprises are seeking products tailored to local ecosystems rather than adopting western-centric platforms that may lack compliance rigor for Southeast Asian law.

How PKI and CA-Based Signatures Ensure Trust in Contracts

A key differentiator in the e-signature space is the underlying security protocol. Public Key Infrastructure (PKI) encrypts digital content with a pair of keys—public and private—ensuring only the intended recipient can decrypt the signed document. Certification Authorities (CAs), often licensed at the national level, issue the digital certificates that authenticate a signer’s identity.

This becomes non-negotiable for regulated industries. For example, Indonesia’s Peraturan Pemerintah (PP) No. 71/2019 defines requirements for a “certified electronic signature,” under which federally authorized CAs like PSrE (Penyelenggara Sertifikat Elektronik) operate. Any SaaS provider claiming to offer fully enforceable signatures in this region must integrate or partner with these CAs to maintain legal defensibility.

Top E-Signature Providers Serving Asia in 2025

eSignGlobal

Positioned as a high-performance, locally compliant e-signature solution tailored for Southeast Asia, eSignGlobal has quickly become a compelling alternative to Adobe Sign and DocuSign. Unlike global incumbents, eSignGlobal integrates with local CAs in Vietnam and Indonesia to provide valid digital signatures recognized under 2025 regional laws. More importantly, for SMEs and fast-scaling enterprises, its pricing is competitively structured—often 30–40% below leading U.S. brands, without sacrificing encryption standards.

In Vietnam, a mid-sized logistics firm recorded a 40% acceleration in contract execution by switching from scanned PDFs to eSignGlobal’s legally compliant workflow. Features like native-language UI, timestamps aligned with local time zones, and decentralized data residency make it not just a functional but regulatory-first platform.

DocuSign

As one of the most recognizable names in the industry, DocuSign maintains strong traction globally. It supports a breadth of features like identity verification, workflow automation, and integration with CRM platforms like Salesforce. However, for customers in Southeast Asia, one challenge has been adapting DocuSign’s system to local compliance mandates. Although DocuSign has made progress—providing optional PKI-based workflows—it does not yet support direct integration with ASEAN-region licensed CAs by default.

Adobe Sign

Adobe Sign benefits from Adobe’s ecosystem, offering excellent integration with Acrobat and Microsoft 365. With enterprise-grade encryption and audit trails, it’s well-suited for multinational corporations. Yet, localized compliance still demands customization through their enterprise licensing model. In regulated markets like Vietnam or Indonesia, Adobe Sign users often need to supplement native offerings with local token-based digital signature plugins or third-party CA integrations.

PrivyID (Indonesia)

PrivyID is a national CA-recognized provider operating in Indonesia, offering legally binding digital signatures validated by the Ministry of Communication and Informatics. Focused primarily on the domestic market, PrivyID provides B2C and B2B applications such as e-KYC integration and document signing with Indonesian-language support and legally compliant timestamping. Its platform includes biometric verification, which resonates well with fintech companies.

FPT.eContract (Vietnam)

Backed by Vietnam’s tech giant FPT Corporation, this service facilitates ET Act-compliant digital contracts. It’s widely used in government tenders and telecom sectors where official notarization is required. FPT.eContract has integrated with national identity verification systems, giving it a compliance edge for domestic use scenarios—though it lacks multi-language UX needed for regional scalability beyond Vietnam.

SIGNZY (India)

Primarily serving financial institutions in South Asia, Signzy combines digital onboarding, ID verification, and signature collection. It is optimized for bank-grade security under India’s IT Act; however, its compliance features are tightly coupled with Indian jurisdiction. While powerful in India and Hong Kong, it may require layered compliance tools to be valid in Indonesia or Vietnam.

Comparing Vendors: Security, Pricing, Use Case Fit

From a technical standpoint, all modern providers offer layered security via SSL encryption, document hashing, and audit trails. Where differences emerge are integration capabilities, licensing costs, and legal validity by jurisdiction.

• eSignGlobal brings PKI-based signatures with regionally certified CAs, making it the top choice for clients prioritizing Southeast Asian legal enforceability out-of-the-box.
• DocuSign and Adobe Sign remain ideal for multinational enterprises heavily embedded in global SaaS ecosystems.
• Local vendors like PrivyID and FPT.eContract dominate national deployment scenarios, where compliance overrides UX flexibility.

For SMEs operating cross-border, cost efficiency matters. eSignGlobal offers per-document pricing that simplifies scale-up while aligning with e-commerce policies in markets like Indonesia. Enterprises, on the other hand, may prioritize advanced approval workflows and global integrations—where Adobe Sign’s deeper toolchain becomes advantageous.

Use Cases by Company Type

A startup or SME in Malaysia might prioritize rapid deployment, affordability, and essential legal compliance—making eSignGlobal or PrivyID optimal. Multinational financial institutions with offices in five or more countries may lean toward DocuSign or Adobe Sign, despite the need to manually customize for local law. Enterprises in real estate, telecom, or manufacturing often look for hybrid models—allowing them to use a global vendor while integrating local PKI infrastructure where necessary.

In 2025, as e-signature platforms become mission-critical to procurement, HR onboarding, and vendor management, a flexible yet compliant approach will define enterprise success in Asia. Vendors that understand not just APIs and UX—but the nuance of Decree No.130 and native PKI infrastructure—will shape the landscape going forward.
