Deploy an isolated, single-tenant document signing instance configured entirely within your private infrastructure perimeter. Designed for legal, HR, and corporate finance teams, our private eSignature platform provides total custody over confidential contracts, signed artifacts, and audit trails without relying on shared public SaaS environments.
Enterprise Features & Capabilities
1. Zero-Trust Authentication & Identity Control
-
Native Single Sign-On (SSO): Full support for Microsoft Entra ID (Azure AD), Okta, and standard OIDC/SAML providers.
-
Granular Access Controls: Enforce mandatory Multi-Factor Authentication (MFA), Conditional Access policies, and Role-Based Access Control (RBAC) across team workspaces.
-
Dedicated Mail Delivery: Pre-configured with authenticated SMTP (or Direct Send over TLS 1.3) using your custom domain, eliminating email spoofing and phishing risks.
2. Streamlined Signature Workflows
-
Reusable Templates & Direct Links: Build standardized contract templates with pre-defined recipient roles, signature field placements, and automated signing sequences.
-
Multi-Party Approvals: Support complex multi-step workflows, carbon copy (CC) recipients, and custom post-signature redirects.
-
Real-Time Tracking: Audit document status instantly with automated notification triggers at every stage of the signing process.
3. Developer-First API & Embedded Signing
-
Embedded UI: Seamlessly integrate signature fields directly into your existing client portal, web app, or internal dashboard using React/Vue components or iframe embeds.
-
REST API & Webhooks: Trigger automated contract generation, bulk sends, and real-time status updates via webhook events.
Compliance & Security Standards
-
Global Legal Compliance: Fully compliant with ESIGN Act, UETA, and 21 CFR Part 11 standards for legally binding digital signatures.
-
Cryptographic PAdES Standard: Uses Advanced Electronic Signatures (PAdES) to ensure signed PDFs are tamper-evident and audit-compliant.
-
Strict Data Sovereignty: Run within your preferred regional geographic boundary (e.g., Hong Kong, APAC, EU) to satisfy local privacy regulations (GDPR, PDPO).
-
Customer-Managed Encryption: All documents, audit logs, and backup snapshots are encrypted at rest using isolated storage keys.
