Security Services Provided by a Digital Signature
Award-winning eSignature solution
What digital signature security services do
Security services provided by a digital signature are the controls that verify identity, protect document integrity, and record signing activity. In practice, the system uses authentication, encryption, and an audit trail to show who signed, when they signed, and what was signed. signNow applies these controls to electronic records so U.S. businesses can manage contracts, approvals, and regulated forms with a clear record of intent and document history.
Why digital signature security matters
It reduces manual handling, supports faster approvals, and helps preserve enforceability under ESIGN and UETA when signer intent, attribution, and record integrity are documented.
Frequent security pain points
Weak identity checks can make it harder to prove who actually signed the record. Missing audit details can leave gaps in the signing history and weaken evidence. Poor retention practices can make it difficult to retrieve records during disputes or reviews. Unclear permission settings can expose documents to the wrong users or approvers.
Who uses digital signature security
Business workflows
Teams handling contracts, approvals, and regulated forms use digital signature security to verify signers and preserve records.
Document types
Documents like leases, patient forms, tax records, and compliance acknowledgments rely on clear attribution and tamper evidence.

Core security features and benefits
signNow combines identity checks, encryption, and record controls to support secure signing workflows across U.S. business and compliance use cases.
Identity checks
Verifies signer identity before the document is accepted, helping reduce attribution disputes and supporting stronger evidence for business and regulated workflows.
Tamper evidence
Locks the signed file against later changes, so edits after signing are easier to detect and challenge if needed.
Audit trail
Captures a time-stamped history of views, clicks, and signatures, giving teams a clearer chain of custody for each record.
Encryption
Encrypts data in transit and at rest, helping protect sensitive documents during transfer, storage, and retrieval.
Access control
Supports role-based access and controlled sharing, so only approved users can view, sign, or route documents.
Record retention
Stores signing activity in a format that supports internal review, legal review, and compliance checks without rebuilding the workflow.
How the signing process works
The signing flow follows a simple sequence that links identity, consent, and record protection from start to finish.
Authenticate: The platform confirms the signer’s identity before access is granted. Sign: The signer reviews the document and applies the signature. Log: The system records timestamps, actions, and document state. Seal: The signed file is sealed and stored for later review.

Real-world use cases
Customer examples show how secure signing supports faster execution, clearer records, and less manual handling in day-to-day work.
Enterprise operations
A NetSuite operations leader needed tighter control over document routing and signature order across business units.
- Right document, right format, right signer order.
The workflow reduced manual follow-up and kept the signing path aligned with system records, which supported faster internal processing and clearer accountability across teams.
Real estate
A property founder needed secure online execution for leases and related forms across mobile and office workflows.
- 100% compliance and built-in security.
signNow supported a paperless process with a clear audit record, helping the team complete documents remotely while preserving evidence of intent, timing, and document integrity.
Best practices for secure signing
A few disciplined controls can improve evidence quality, reduce access risk, and make later reviews easier for legal, operations, and compliance teams.
