Advanced Electronic Signature AES for Secure Signing
Award-winning eSignature solution
What advanced electronic signature AES means
An advanced electronic signature AES is an electronic signature that is linked to one signer, can identify that signer, is created under the signer’s sole control, and is tied to the signed data so later changes are detectable. In U.S. practice, it supports signed agreements by pairing identity checks, consent, and a tamper-evident record. signNow applies this through signer authentication, audit trails, and document integrity controls that help preserve evidence of who signed, when, and what was signed.
Why AES matters for U.S. signing
AES helps organizations reduce paper handling, speed approvals, and preserve evidence for disputes. Under ESIGN and UETA, electronic signatures can be enforceable when intent, consent, and attribution are supported, and signNow provides audit trails and controls that help document those requirements.
Common AES implementation issues
Proving signer identity when the transaction needs stronger attribution than a simple click-to-sign flow. Keeping the audit trail complete when teams use email, mobile, and shared document workflows. Meeting retention and access-control rules for regulated records without losing searchability or version history. Choosing the right authentication level for healthcare, finance, or other higher-risk documents.
Who uses AES in practice
Business use
Organizations use AES for contracts, approvals, and regulated records that need stronger identity evidence and traceability.
Document types
Teams use AES for leases, patient forms, financial approvals, and internal policy acknowledgments.
People who benefit from AES
Real estate operations leaders at firms like Martin Properties use signNow to execute leases and rental paperwork online while keeping mobile signing and compliance evidence in one workflow. NetSuite operations teams, such as Xerox’s, use signNow to route documents by format and approval path, which helps keep signatures aligned with ERP-driven business processes.

Key AES capabilities in signNow
signNow combines identity checks, record integrity, and workflow controls so AES documents move quickly while preserving evidence and reviewability.
Signer identity
Signer authentication links each signature to a verified person, helping teams support attribution and reduce disputes over who approved the record.
Tamper evidence
Tamper-evident records show whether a document changed after signing, which helps preserve integrity for contracts and regulated files.
Audit trail
Audit trails capture timestamps, actions, and signer events, giving reviewers a clear record of the signing sequence.
Templates
Templates reduce repetitive setup for recurring forms, so teams can send the same AES workflow with fewer manual steps.
Mobile signing
Mobile signing lets people review and sign on phones or tablets, which helps keep approvals moving outside the office.
Role routing
Role-based routing sends documents in the right order, which helps legal, HR, and operations teams manage approvals consistently.
How AES works step by step
AES follows a simple sequence: prepare the file, verify the signer, capture the signature event, and preserve the signed record.
Prepare: The sender prepares the document and chooses the signing order. Authenticate: The signer receives a secure request and completes identity checks. Record: signNow records each action, timestamp, and document event. Seal: The signed file is sealed and stored with its audit trail.

Recommended AES workflow settings
A practical AES setup should balance signer assurance, record integrity, and retention needs for U.S. business and regulated workflows.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP with ID verification |
| Signature type | AES with tamper evidence |
| Audit trail | Full event log with UTC timestamps |
| Document retention | 6 years for HIPAA records |
| Encryption | TLS 1.2/1.3 and AES-256 |
Platform requirements for AES signing
AES signing works across modern browsers and mobile devices, with secure connections and app support for desktop and phone workflows.
Desktop browsers Chrome, Firefox, Edge Apple devices Safari on iOS, macOS Mobile and desktop Android app, Windows app
For managed deployments, teams should confirm browser policy, device access, and account provisioning before rollout. signNow supports browser-based signing on Windows and macOS, plus mobile workflows on iOS and Android.

Real-world AES use cases
Customer stories show how AES supports document control, compliance evidence, and faster turnaround in everyday business workflows.
Real estate
A real estate team needed faster lease execution without losing evidence of consent or signer identity.
- Martin Properties used mobile signing for remote lease workflows.
The team processed documents online with 100% compliance and built-in security, while mobile and offline access helped keep forms moving to the right parties.
ERP operations
An operations group needed ERP-linked routing so the right documents reached the right approvers in the right format.
- Xerox used signNow with NetSuite integration.
The workflow matched document format to business process, which improved routing control and supported faster signature collection across connected systems.
Best practices for AES workflows
A careful AES rollout depends on identity controls, document governance, and repeatable review steps that fit the transaction’s risk level.

signNow Business includes legally binding eSignatures, audit trails, templates, mobile apps, ISO 27001, SOC 2, and GDPR support. If you need HIPAA workflows, use a BAA and confirm the account is configured for PHI handling.
signNow supports audit trails that record signer actions, timestamps, and document history. For regulated records, that evidence helps support ESIGN, UETA, and HIPAA Security Rule expectations for integrity and audit controls.
If a signer cannot complete authentication, review the method used. SMS OTP, ID verification, and other higher-assurance methods can be adjusted in the workflow, and signNow’s enterprise options add stronger signer authentication controls.
The Business plan is priced at $8/user/mo billed annually, and all paid plans include unlimited users. If you need bulk send, use Business Premium or higher; if you need SSO or full API access, Site License adds those options.
For healthcare records, HIPAA retention is 6 years from the date of creation or last effective date, whichever is later, under 45 CFR 164.530(j)(2). Keep the signed file and audit trail together for review and retention.
If a document must support FDA-regulated records, use controls aligned with 21 CFR Part 11, including unique user identification, secure audit trails, and validated workflows. signNow’s compliance features help support those requirements, but validation remains the customer’s responsibility.
