Don't waste any more time printing documents to be signed, chasing signatories by email or scanning and archiving manually.
Octopussian natively integrates eIDAS-compliant electronic signatures:
legal, simple and fast, for all your professional contracts.

The challenge: optimising your signature processes

Traditional signature processes slow down your operations:
printing documents, collecting handwritten signatures, scanning, archiving, multiple reminders to absent signatories.
A contract can take several days to finalise , whereas the commercial agreement is concluded in a matter of minutes.

Added to these delays are operational costs that are often underestimated: printing, postage, electronic signature solutions billed per use, which put a strain on your budget as soon as your volume increases.

Octopussian transforms this process : legal signatures in just a few clicks, included in your subscription, with no extra cost per document.

Increase efficiency and control your costs

Drastically reduce your signing times

Eliminate manual steps: printing, postage, scanning.
Your signatories receive a secure link and sign from their browser in less than a minute

Contracts that used to take several days are now completed in a matter of hours.

A pricing model tailored to SMEs

Electronic signatures are included in your Drive subscription.
No per-signature billing, no surprises at the end of the month. Your budget remains predictable, regardless of your monthly volume.

This all-inclusive approach allows you to deploy electronic signatures throughout your organisation without worrying about volumes or peaks in activity.

Security and technical compliance

Our signature infrastructure is based on industry-proven standards:

Private key stored in a FIPS 140-3 certified HSM Tamper-proof
hardware security module ensuring that the signature key can never be extracted or copied.

Advanced seal recognised by the European Union
Included in the Adobe Approved Trust List (AATL) for automatic recognition by all professional PDF readers .

Full traceability of each signature Immutable
record of the signatory's identity, precise timestamp (NTP synchronised), IP address, cryptographic fingerprint (SHA-256 hash), and explicit consent. In the event of a dispute, you have a comprehensive audit trail .

Compliance with European and American regulations Advanced
electronic seal compliant with Article 36 of the European eIDAS Regulation (No. 910/2014) and compatible with the American eSign Act standard.

Our technical approach
Octopussian uses an organisational electronic seal issued by Certigna. Each signatory gives their consent via secure authentication (email + unique link), all of which is cryptographically sealed with our advanced eIDAS certificate. This approach is legally equivalent to a handwritten signature for 95% of professional needs.

Can I use the Octopussian signature for all my procedures?
The Octopussian advanced electronic seal is designed for professional documents issued by your organisation: commercial contracts, HR documents, agreements, mandates, confidentiality agreements, etc.
However, it is not suitable for personal administrative procedures requiring an individual qualified certificate (tax returns, social security procedures, notarial deeds). For these specific cases, you will need to use a dedicated qualified signature solution.
Our solution is ideal for any document that your company issues and has its customers, partners or employees sign.

An integrated and predictable offer
