The Intellistack Streamline Sign Step provides a secure and compliant way to collect electronic signatures while maintaining a complete, tamper-evident record of the signing process. This article explains what appears in the Streamline audit trail, how Streamline ensures signature integrity, and the broader security and compliance framework behind our eSignature capabilities.

What Makes an Electronic Signature Legally Valid?

Electronic signatures collected through Intellistack Streamline are designed to support the core legal requirements outlined under major global eSignature frameworks, including:

• U.S. ESIGN Act
• U.S. UETA
• EU eIDAS Regulation (SES level) via adherence to ETSI EN 319 142 / PAdES Baseline standards

These frameworks require signatures to demonstrate:

1. Intent to sign
2. Consent to do business electronically
3. Attribution to a specific person
4. Association of the signature with the document
5. Record retention suitable for evidentiary use

Intellistack Streamline is engineered to support these requirements.

What’s Included in the Streamline Audit Trail

When someone signs a document in Streamline, the system automatically generates a detailed audit trail capturing key metadata for legal and compliance purposes. This includes:

• Signer name
• Email address
• Timestamp (with time zone)
• IP address
• Device details (when available)
• Browser details
• Event history, including when the document was opened, viewed, and signed

This audit trail appears alongside the finalized document and provides clear, unambiguous attribution of signature activity. Example below. 

Where the Audit Trail Lives

All signed documents and their metadata are stored in the Streamline Repository, ensuring:

• Immutability of signed files
• Preservation of audit history
• Full traceability of document events

Changes to document status—such as deletion, completion, or workflow updates—are also tracked via Streamline’s system-wide audit logs.

Signature + Document Integrity:

GlobalSign Digital Certificates & Tamper Evidence

Intellistack Streamline applies a cryptographic seal to every signed document using a certificate from GlobalSign, a globally trusted Certificate Authority (CA).

Why this matters

• Documents are cryptographically sealed upon completion
• Any post-signature tampering becomes immediately detectable
• Long-term validation (LTV) is supported through embedded OCSP/CRL responses
• Ensures legal defensibility during audits or disputes

Streamline signature processing aligns with industry standards including:

• ISO 32000 (PDF specification)
• ISO 14533 (long-term signatures)
• RFC 3161 (trusted timestamps via GlobalSign TSA)
• X.509 full-chain validation
• SHA-256/RSA cryptographic integrity

These controls extend trust from Streamline’s platform all the way down to the certificate infrastructure behind each signed document.

Record Retention in Streamline

Streamline provides flexible retention controls to meet a variety of compliance requirements:

• Signed documents are stored securely in the Repository
• Admins can choose to delete documents and associated metadata if required
• Organizations may also disable in-platform storage entirely, allowing external content systems to serve as the authoritative record

These features support organizations with strict requirements around:

• Data minimization
• Regional data sovereignty
• Internal records-management policies
• Legal hold / retention workflows

Streamline’s Security & Compliance Posture

Intellistack Streamline is built on a strong security and compliance foundation, including:

Cryptographic & Certificate Assurance

• Digital signatures applied using GlobalSign
• Tamper-evident document sealing
• Trusted timestamps from a GlobalSign TSA
• Compliance with major CA frameworks:
  • WebTrust for CA
  • eIDAS Qualified Trust Services
  • ISO/IEC 27001
  • CAB Forum Baseline Requirements

Platform-Level Security

• SOC 2 Type 2 certification
• HIPAA Security Rule alignment (Streamline available under BAA)
• Role-based access controls (RBAC)
• Secure audit logs across the platform
• Automatic data classification
• Strong authentication and access policies

These capabilities help ensure that signatures collected through Streamline are both legally enforceable and protected under modern security standards.
