SES, AES, and QES: which signature level do you need?

Nitro Sign Enterprise Verified supports all three electronic signature levels under eIDAS, so you can apply the right level of identity assurance and legal certainty to each transaction.
Level One

Simple Electronic Signature (SES)

A straightforward electronic signature for lower-risk, everyday agreements. This can include actions such as typing a name, drawing a signature, or clicking to accept.

Level Two

Advanced Electronic Signature (AES)

Provides stronger assurance by linking the signature to an identifiable signer and helping detect changes made to the document after signing. Suited to higher-value or business-critical agreements.

Level Three

Qualified Electronic Signature (QES)

The highest-assurance electronic signature under eIDAS. A Qualified Electronic Signature has the equivalent legal effect of a handwritten signature across the EU, making it suitable for regulated and high-stakes transactions.
