About SIGN.PLUS
Sign.Plus is an electronic signature platform provided by Alohi, a Swiss-based company focused on secure communication and document management. The service is designed to replace traditional paper-based signing with a digital workflow that complies with major international regulations including eIDAS (EU), ZertES (Switzerland), and ESIGN (USA). It provides various levels of signatures, including Qualified Electronic Signatures (QES) which carry the same legal weight as a handwritten signature. The platform is built with a heavy emphasis on security and privacy, featuring data residency options for enterprise clients, 256-bit AES encryption for stored documents, and a zero-knowledge architecture approach where each user has unique encryption keys. As a Swiss company supported by Innosuisse (the Swiss Innovation Agency), it positions itself as a sovereign European alternative to US-based eSignature giants, specifically targeting sectors with high compliance requirements such as healthcare, legal, and finance.
