Quickly and reliably validate digital signatures and signing rights.
A digital signature on its own is not enough for a legally valid signing – what really matters is the person’s authority. That’s why DeepValidator not only checks the signature but also cross-references the signing authority in real time with the Swiss Commercial Register, and confirms that the required quorum has been met, ensuring that documents are signed only by authorised individuals.
Forget about using multiple solutions: our signature validator handles the complete verification. Digital signatures and seals are checked against Swiss ZertES and EU eIDAS standards, ensuring the validity of qualified electronic signatures and seals within seconds.
DeepValidator works with DeepSign and all other signature providers, letting you validate any signature or seal, regardless of who issued it. Thanks to DeepInfos integration, our signature validator also verifies whether the signer is authorised to represent a Swiss-based company, making the process simple and legally secure.
DeepValidator verifies qualified electronic signatures and qualified or regulated electronic seals with an authority certificate, in accordance with the recognised standards in Switzerland (ZertES) and the EU (eIDAS).
