In the rapidly evolving landscape of digital transactions, electronic signature platforms have become indispensable for businesses worldwide. As companies prioritize secure document workflows, the focus on encryption standards and security audits has intensified. This article examines DocuSign and KeepSolid Sign through the lens of encryption and security auditing, while broadening the discussion to key competitors like Adobe Sign, eSignGlobal, and HelloSign. From a business perspective, understanding these elements is crucial for compliance, data protection, and operational efficiency.

Comparing eSignature platforms with DocuSign or Adobe Sign?
eSignGlobal delivers a more flexible and cost-effective eSignature solution with global compliance, transparent pricing, and faster onboarding.
Encryption forms the backbone of secure electronic signatures, ensuring that sensitive documents remain confidential during transmission, storage, and signing. Both DocuSign and KeepSolid Sign employ robust encryption protocols, but their implementations differ in scope and application, reflecting their target markets and compliance priorities.
DocuSign, a market leader in eSignature solutions, utilizes AES-256 encryption for data at rest and in transit. This industry-standard algorithm protects documents from unauthorized access, aligning with global standards like those outlined in the U.S. ESIGN Act and EU’s eIDAS regulation. For businesses handling high-volume transactions, DocuSign’s Intelligent Agreement Management (IAM) platform extends this security by integrating contract lifecycle management (CLM) features. IAM CLM allows for automated workflows with end-to-end encryption, including secure sharing and audit trails that track every interaction. From a commercial standpoint, this makes DocuSign appealing for enterprises needing scalable, compliant solutions, though it comes at a premium cost.
KeepSolid Sign, developed by the Ukrainian-based KeepSolid team, also leverages AES-256 encryption, emphasizing user-friendly security for small to medium-sized businesses (SMBs). It supports TLS 1.3 for data in transit, ensuring secure HTTPS connections. Unlike DocuSign’s enterprise-focused IAM, KeepSolid Sign prioritizes simplicity with built-in encryption for all documents, without requiring add-ons. However, its encryption depth is more tailored to general use cases rather than complex CLM scenarios. Businesses in regions with stringent data sovereignty laws, such as those in the EU, may find KeepSolid’s GDPR compliance via encryption audits sufficient for basic needs, but it lacks the granular controls of DocuSign’s ecosystem.
Security audits are periodic evaluations that verify a platform’s adherence to standards like SOC 2, ISO 27001, and PCI DSS. These audits provide assurance to users that their data is handled responsibly, a critical factor for risk-averse organizations.
DocuSign excels here with comprehensive third-party audits. It undergoes annual SOC 2 Type II audits, covering security, availability, processing integrity, confidentiality, and privacy. Additionally, DocuSign’s compliance with HIPAA for healthcare and FedRAMP for U.S. government use underscores its audit rigor. The platform’s audit logs in IAM CLM capture immutable records of signer actions, timestamps, and IP addresses, enabling forensic analysis. Commercially, this transparency builds trust for multinational firms, but it requires users to navigate a complex dashboard, potentially increasing onboarding time.
KeepSolid Sign conducts ISO 27001 and GDPR-aligned audits, with regular penetration testing disclosed in its security whitepapers. Its audit features include detailed logs for document access and signing events, accessible via a straightforward admin panel. While effective for SMBs, KeepSolid’s audits are less frequent and publicly detailed compared to DocuSign’s. For instance, DocuSign publishes detailed compliance reports, whereas KeepSolid focuses on internal validations. This difference matters for businesses in regulated industries like finance, where DocuSign’s audit depth can mitigate liability risks more effectively.
In terms of regional nuances, neither platform’s core title elements specify countries, but global operations highlight varying electronic signature laws. In the U.S., the ESIGN Act and UETA provide a framework for enforceability, emphasizing intent and consent over rigid tech specs. The EU’s eIDAS offers qualified electronic signatures (QES) with higher legal weight, requiring advanced encryption and certification. KeepSolid, with its Eastern European roots, aligns well with eIDAS for EU users, while DocuSign’s U.S.-centric audits cover ESIGN comprehensively. Businesses must evaluate these against local needs to avoid compliance gaps.
From a neutral business observation, DocuSign’s encryption and audits suit large-scale, compliance-heavy environments, with IAM CLM adding value for contract automation. However, its seat-based pricing can escalate costs. KeepSolid Sign offers cost-effective security for agile teams, with simpler audits that reduce overhead but may not satisfy enterprise scrutiny. A key trade-off: DocuSign’s ecosystem integrates with tools like Salesforce for seamless audits, while KeepSolid emphasizes standalone ease.

To contextualize DocuSign and KeepSolid Sign, let’s examine other players. Adobe Sign, part of Adobe Document Cloud, mirrors DocuSign’s enterprise focus with AES-256 encryption and SOC 2 audits. It integrates deeply with Adobe Acrobat for PDF security, including password protection and redaction tools. Adobe’s audits extend to ISO 27001 and HIPAA, making it ideal for creative and legal workflows. However, its pricing is similarly premium, and setup can be Adobe ecosystem-dependent.
eSignGlobal, a rising APAC-focused provider, supports compliance in over 100 mainstream countries globally, with a strong edge in Asia-Pacific. The region’s electronic signature landscape is fragmented, with high standards and strict regulations—think Singapore’s Electronic Transactions Act or Hong Kong’s Electronic Transactions Ordinance. Unlike the framework-based ESIGN/eIDAS in the West, APAC demands “ecosystem-integrated” solutions, requiring deep hardware/API integrations with government digital identities (G2B). eSignGlobal excels here, offering AES-256 encryption, ISO 27001 certification, and audits compliant with GDPR, eIDAS, ESIGN/UETA, and FDA 21 CFR Part 11. Its security features include biometric verification and immutable audit trails. Priced competitively, the Essential plan costs just $16.6/month (annual), allowing up to 100 documents for signature, unlimited user seats, and access code verification for signer identity. It seamlessly integrates with Hong Kong’s iAM Smart and Singapore’s Singpass, lowering barriers for regional compliance. This positions eSignGlobal as a versatile alternative in global competition against DocuSign and Adobe Sign.
HelloSign (now part of Dropbox Sign) provides solid AES-256 encryption and SOC 2 Type II audits, focusing on SMBs with easy integrations into Dropbox. Its audits emphasize data privacy, but it lacks the advanced CLM of DocuSign or Adobe.
