What an on premise digital signature entails

An on premise digital signature solution installs within an organization’s local IT environment and applies cryptographic signing to electronic documents without relying solely on third-party cloud services. For U.S. organizations this model supports data residency requirements, tighter control over encryption keys, and integration with internal authentication systems such as Active Directory. On premise deployments can be configured to meet sector-specific controls for healthcare, education, financial services, and government, while enabling audit trails and legally admissible signatures under ESIGN and UETA when implemented according to applicable standards.

Why choose an on premise digital signature approach

On premise deployment gives organizations direct control over infrastructure, key management, and data residency, which can simplify compliance with strict regulations and internal security policies while maintaining signature validity under U.S. law.

Why choose an on premise digital signature approach

Common implementation challenges

  • Higher upfront infrastructure and maintenance costs compared with cloud-only options, including servers and IT staffing.
  • Longer deployment timelines due to network configuration, security reviews, and on-site testing requirements.
  • Responsibility for backups, disaster recovery, and patching rests entirely with the deploying organization.
  • Integrating with legacy systems and ensuring mobile access can require additional development and security planning.

Typical users and administrators

IT Manager

Responsible for installation, patching, and network configuration of the on premise digital signature platform. Coordinates with security and compliance teams to ensure system hardening, monitoring, and backups meet organizational standards.

Compliance Officer

Defines retention policies, ensures signature records meet ESIGN and UETA requirements, and manages audits. Reviews access controls, consent flows, and legal admissibility for signed documents across business units.

Which teams typically adopt on premise digital signature

Organizations with strict data residency needs or regulatory mandates often prefer on premise digital signature deployments to retain control over sensitive records.

  • Healthcare providers managing patient records and HIPAA-covered data.
  • Educational institutions protecting student records under FERPA.
  • Financial services and government agencies with strict audit and retention policies.

Teams that require integration with internal identity providers, custom key management, or isolated networks commonly choose on premise options for predictable operational control.

Industry scenarios using on premise digital signature

Real-world implementations show how keeping signature systems on site addresses both regulatory and operational needs across sectors.

Healthcare contract workflow

A regional health system deployed an on premise digital signature server to sign patient consent and clinical agreements under controlled key management.

  • Role-based templates streamlined clinician approvals.
  • Reduced third-party data transfer risk while preserving audit logs.

Resulting in strengthened HIPAA control and more repeatable audit evidence across facilities.

Financial services onboarding

A mid-size bank implemented an on premise signing appliance to capture KYC and account agreements within its private network.

  • Integration with internal identity provider enabled single sign-on.
  • Maintained transaction auditability and retention aligned with banking regulations.

Resulting in clearer compliance posture, lower exposure to external breaches, and more efficient internal reviews.

Operational best practices for on premise digital signature

Adopt practices that reduce risk, improve reliability, and maintain the evidentiary value of signed records across the organization.

Maintain HSM-backed key control and rotation
Implement hardware security modules for private key storage, define formal rotation and backup procedures, and restrict key access to designated security roles to protect signature integrity and meet forensic needs.
Enforce multi-factor authentication for administrative access
Require MFA for administrators and privileged users, integrate with SSO and conditional access policies, and separate duties between administrators and compliance reviewers to reduce insider risk.
Regularly test and validate audit trails
Periodically verify that logs capture required events, perform tamper checks on stored artifacts, and rehearse retrieval procedures to ensure signed documents remain verifiable during audits or legal review.
Document retention and legal hold procedures
Define and enforce retention schedules consistent with regulatory and business needs, ensure archived signed records are immutable, and implement legal hold processes to preserve records when litigation is possible.

Standard workflow inside an on-premise eSigning solution

In our previous lesson we have learnt what needs to be done for implementation of an on-premise solution and how to start using it.

In this lesson, we will have a look at how it actually works and what is the usual flow of operations inside the on-premise solution on the example of eSigning via airSlate SignNow.

Using airSlate SignNow on premises, you will be able to enjoy the same functionalities as in web-based airSlate SignNow, namely:

  • Sending documents for eSigning to one or multiple recipients (in a particular order if needed);
  • Creating templates out of the most frequently used documents for further multiple re-use;
  • Generating eSigning links for public posting (on your website, in a blog or on social media platforms);
  • Tracking document status using document audit trail;
  • Organizing online teamwork using shared folders for separate teams inside one organizations and creating complex workflows between them.

There is no difference in terms of usability or interface between web-based airSlate SignNow and airSlate SignNow on-premises. Only the admin, as the person responsible for settings' configuration and backups, would notice the difference, while there is none for all other users in your office.

Of special importance in eSigning on premises is the feature of secure backup. Since all the data is stored on the corporate server inside the organization, the admin is expected to specify a repository for regular backup so that data can be easily restored after unexpected system events.

Backup settings in airSlate SignNow, on-premise version, look as follows:

Reaching out to Support:

Keep in mind that as we are talking about a closed system here, requesting assistance from Support means you need to 'open the gates' on your side:

To enable remote access for an airSlate SignNow Support rep, the system administrator on your side needs to initiate a SSH Support Tunnel. Opening this tunnel would involve the creation of a temporary login token which is then shared with airSlate SignNow Support for authentication purposes. Once the tunnel is closed - this token self-destroys automatically.

In system configurations this looks as follows:

Another peculiar feature of using airSlate SignNow on premises is that it does not require a separate log in from all the users inside your organization (unlike the web version in which you would need to use email and password for login):

airSlate SignNow on-premise solution can be connected to the local LDAP server - Lightweight Directory Access Protocol which stores all the existing credentials. This means users wouldn't even have to register at airSlate SignNow to start eSigning and sending for signing. They have accounts by default, and these accounts are based on the contact data stored in the local directory database.

Most of business users of airSlate SignNow on-premise solution would find this feature of automated login convenient, however, for extra security, the system administrator can actually enable both registration and verification as in the standard version of web-based airSlate SignNow:

Let's sum up the key takeaways from this lesson:

  • eSigning functionalities of airSlate SignNow on premises are absolutely the same with the functionalities of its web-based version. Apart from registration and login which can be both significantly simplified.
  • Timely backups and requesting support would require some additional work on the side of system administrator.
