√ SIGN.PLUS recognized as the best e-Signature solution to fill and sign documents!

◆ Fill and sign documents: SIGN.PLUS allows you to create an electronic signature to e-sign documents wherever you are and whenever you want. You can draw a signature, type your signature or use your initials.

◆ Send documents for signature: Other than the option to fill and sign documents yourself, you can also send documents for signature. You can send a request for signature even if the signees do not have a SIGN.PLUS account. You can add various fields to the documents, including signature, initials, date, text, and checkbox.

◆ Tamper-proof audit trails: For every document that goes into the process of signing electronically, there are real-time logs to keep track of any activity that has occurred with information such as name, IP address, email address, device, and much more. The audit trails are non-editable and each document action is thoroughly tracked and time-stamped, serving as legal proof of receipt, review, and signature.

◆ Legally-binding electronic signature: SIGN.PLUS complies with electronic signature regulations such as ESIGN, eIDAS, and ZertES to ensure it delivers the same legal standing as pen-and-paper signatures.

► Extensive security measurements and compliance offerings

◆ Data encryption: We encrypt all documents at rest using 256-bit Advanced Encryption Standard (AES), with each user’s unique encryption key. Furthermore, to protect data in transit between our apps (currently mobile, API, web) and our servers, we use TLS 1.2+ encryption.

◆ Various compliance offerings: We are committed to certifying ourselves and our e-signing platform for all relevant certifications and compliances, including SOC 2, HIPAA, ISO 27001, GDPR, CCPA, and more.

Ease of Use
