Esignature Security System for Secure SignNow Workflows
Award-winning eSignature solution
What an eSignature security system does
An eSignature security system is the set of identity checks, encryption controls, audit logs, and record safeguards that protect electronic signing. It verifies who signed, captures when and how the action happened, and preserves the document in a tamper-evident form. In the U.S., this helps organizations support ESIGN and UETA requirements while keeping signing workflows fast, remote, and easier to review later.
Why eSignature security matters
A secure eSignature process reduces fraud risk, speeds approval cycles, and creates evidence that supports enforceability under ESIGN and UETA. It also helps teams keep a clear record of signer intent, identity, and document integrity for business and compliance review.
Common eSignature security issues
Weak signer verification can make it harder to prove who actually approved the document. Missing audit details can leave gaps in the signing record and slow dispute review. Poor retention practices can make signed records difficult to retrieve during audits or litigation. Unclear consent or disclosure steps can weaken electronic delivery and signing workflows.
Who uses secure eSignatures
Healthcare
Healthcare teams use secure eSignatures for patient forms, consent records, and HIPAA-sensitive workflows.
Real estate
Real estate and finance teams use them for leases, loan packets, and approval chains.
Typical users and personas
At Optica Ventures LLC, COO Brian Fitzgibbons described the interface as simple for both internal teams and customers. That matters in sales, operations, and client onboarding, where a secure signing flow must stay easy to use while still preserving auditability and document control. At Xerox, Director of NetSuite Operations Kodi-Marie Evans said signNow gave the team flexibility to get the right signatures on the right documents in the right formats. That fits enterprise operations teams that need secure signing tied to ERP-driven document routing and approval rules.

Core security features
Secure signing depends on identity, integrity, and recordkeeping controls that keep the workflow usable while preserving evidence.
Identity checks
Verifies signer identity with authentication options that fit different risk levels, from simple access checks to stronger two-factor methods.
Audit trail
Captures a time-stamped record of each action so teams can review the signing sequence later.
Encryption
Uses encryption in transit and at rest to protect documents during transfer and storage.
Tamper evidence
Supports tamper-evident records so later changes are easier to detect during review.
Record storage
Stores completed files in a way that supports retrieval, retention, and internal audit needs.
Flexible access
Works across desktop and mobile workflows without forcing users into a paper process.
How the process works
A secure eSignature workflow follows a short sequence from identity check to sealed record.
Verify identity: The system checks signer identity before the document opens. Sign document: The signer reviews the file and applies an electronic signature. Log activity: The platform records timestamps, events, and document changes. Seal record: The completed file is sealed and stored for later review.
Quick setup steps
Use a short setup flow to prepare, send, and store secure signing requests.
Prepare file:
Upload the document and assign the signer fields. Set verification:
Choose the authentication method for the signer. Send request:
Send the request and monitor completion status. Archive result:
Download the completed record and store it securely.
Recommended workflow settings
A secure setup starts with identity verification, clear record retention, and encryption that protects both transit and storage.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP for routine approvals |
| Signature type | SES for low-risk forms |
| Audit trail | Enable full time-stamped logging |
| Document retention | 6 years for HIPAA records |
| Encryption | TLS 1.2/1.3 and AES-256 |
Platform and system requirements
Use a modern browser or mobile device with secure HTTPS access to complete and review eSignature workflows.
Desktop browsers Chrome, Firefox, Safari, and Edge Operating systems Windows, macOS, iOS, and Android Connection security TLS 1.2 or TLS 1.3
For regulated deployments, managed devices, access controls, and retention policies matter as much as browser support. Teams should also confirm mobile access, user provisioning, and any required compliance settings before rolling out signing workflows across departments or external counterparties.

Real-world examples
Customer stories show how secure signing fits enterprise operations, property workflows, and regulated document handling.
Enterprise operations
A finance or operations team needs secure routing for high-volume approvals and customer-facing documents.
- Tech Data used signNow to improve internal and external customer service.
- The team linked signing to faster revenue operations.
Tech Data’s example shows how secure eSignature workflows can support speed, service, and controlled document handling in large organizations.
Real estate
A real estate team needs mobile signing, clear records, and secure execution for leases and related forms.
- Martin Properties processed documents online with built-in security.
- The workflow worked on mobile and offline.
Martin Properties illustrates how secure signing can reduce paper handling while preserving compliance, mobility, and document traceability for property workflows.
Best practices for secure signing
Good controls make the signing process easier to review, easier to defend, and less likely to break under audit or dispute.

FAQ and troubleshooting
These answers focus on plan limits, compliance requirements, and recordkeeping issues that affect secure signing workflows.
signNow supports legally binding eSignatures under ESIGN and UETA, and paid plans include audit trails. If you need HIPAA workflows, confirm a BAA and use the appropriate plan and controls before handling PHI.
For HIPAA workflows, signNow can be used with a BAA, and signed records containing PHI should be retained for 6 years under 45 CFR 164.530(j)(2). Keep audit trails and access controls enabled for every record.
The Business plan starts at $8/user/mo with annual billing. Business Premium adds bulk send, and Enterprise adds advanced signer authentication. If a feature is missing, check whether it belongs to a higher plan tier.
signNow provides audit trails that record signer activity, timestamps, and document history. If a record looks incomplete, confirm the signer finished the workflow and that the completed file was downloaded or stored after signing.
signNow supports unlimited users on paid plans, but the Site License is usage-based at $1.50 per signature invite. If you need SSO or full API access, review the Site License and Enterprise options.
For regulated use, signNow supports controls relevant to 21 CFR Part 11, including timestamps, audit history, and access controls. Validate your workflow before use in FDA-regulated records, because the process must fit the predicate rule.
