Details on advanced electronic signatures – high security, without complexity
What is an advanced electronic signature?
Advanced signatures, also known as ‘level 2 electronic signatures’, offer an excellent balance between legal certainty and ease of use.
They are based on three essential pillars:
Signatory authentication
Unique link between signature and identity
Guaranteed document integrity
In other words: you know who signed, under what conditions, and the document could not be modified after signing.
Why is this important to you?
In the legal, financial, HR, and real estate sectors, a simple signature is often no longer sufficient.
Using an advanced signature means:
Protect your contracts against any disputes
Give your documents strong probative value
Speed up your processes without sacrificing compliance
You reduce legal risks while increasing efficiency.
When should you use advanced signature?
Advanced signatures are ideal for documents with high contractual value or involving significant commitments:
Commercial contracts
Purchase orders
HR documents (job offer, amendments, etc.)
Mandates, agreements
Regulated documents requiring proof of identity
It is recommended when the stakes are high, but a qualified signature (level 3) is not legally required.
