| Integrations | DigiSigner says it does not offer a direct Zapier integration, but describes using Gmail as an intermediary; that workflow works only with one signer. | Documents can be integrated manually, retrieved from a folder, or injected through a web service; document stores such as Nuxeo and Alfresco can connect through CMIS. |
| Security | DigiSigner says documents are stored behind a firewall, requests are authenticated against the user session, and communications use SSL encryption. | For hardware-backed signing, Esup-DSS-Client can use a certificate stored on a physical key so the certificate does not leave that key. |

In their own words
DigiSigner
DigiSigner is a web-based service for signing documents and requesting signatures from others. Users upload a document, create a signature by drawing with a mouse, typing a name, or inserting a signature image, then invite other signers and receive a completion notification. The service lists an audit trail, templates, bulk sending, and signature-order options. PRO and TEAM include templates, branding, and signing links; PRO allows one sender, while TEAM allows up to five senders and adds team features. DigiSigner also offers API access through a REST-style interface using JSON, with PHP, Java, and C# client libraries. Production API use requires a PRO or TEAM subscription and API credits. The company says its signatures comply with ESIGN, UETA, and European eIDAS and are legally binding. It serves real estate, human resources, legal, and small business users. The free plan is free and includes three documents per month; PRO is $15 a month billed annually, and TEAM is $50 a month billed annually. A 14-day trial is available.
Esup-Signature
Esup-Signature is free, open-source software for building document-signing workflows, sending documents to sign, and tracking completion with proof. Workflows can set signers, signature types, and whether everyone at a step must sign. Supported operations include verification and visa, as well as simple, advanced, and qualified electronic signatures. When a workflow mixes signature levels, simple signatures must precede advanced or qualified ones. Any document format can be signed, but only PDFs show a visual signature; other formats use XAdES signatures. The software can check document integrity and display proof files, and it uses the European Commission’s DSS solution for eIDAS signatures and certificate-based verification. PDF forms can become web forms and draw prefilled data from institutional LDAP or custom sources. Users can delegate signing or data entry and transfer requests. Esup-Signature is free at free under the Apache 2.0 license. It is not offered as a hosted service and must be installed on an institution’s own server.
