QES: The gold standard in digital signatures
In a business world that is digitizing faster than ever, trusting the technology you use is essential. For freelancers, SMEs, and accountants, the digital signature has become a powerful tool. But when it comes to documents with significant legal impact, there is only one true "Gold Standard": the Qualified Electronic Signature (QES).

What makes a digital signature legally valid?
A digital signature is the electronic equivalent of a pen-and-paper signature. However, to hold the same legal weight, a signature must meet strict criteria:
Authenticity: The signature must irrefutably confirm the identity of the signer.
Integrity: It must be technically impossible to alter the document after signing without it being detectable.
Non-repudiation: The signer cannot later deny having signed the document.

Why are QES signatures so special?
The Qualified Electronic Signature (QES) represents the highest level of security within the European eIDAS regulation. What makes QES unique is that it is the only digital signature level that is legally fully equivalent to a handwritten signature on paper.
While other forms of digital signatures may require additional evidence in the event of a dispute, QES provides the highest form of proof. This is crucial for documents such as notary deeds, mortgage documents, insurance policies, and official employment contracts.
How does identity verification work?
The "secret" of a QES lies in the verification. Before you can apply a qualified signature for the first time, your identity must be thoroughly established by a recognised authority. This process guarantees that the digital key being used truly belongs to you.
Today, this process is entirely digital and fast. Using methods such as itsme or reading your eID card, you can confirm your identity in moments and start using QES immediately. Additionally, multi-factor authentication (such as a PIN or biometric scan) is always required for every individual signature.
When should you choose QES?
While a simple signature often suffices for daily approvals, a QES is indispensable in situations with major legal or financial stakes. In these cases, a QES offers not only legal certainty but also peace of mind. It is the ultimate guarantee that your documents are and remain authentic.
