Electronic Document Signing,

Secure and Simple

Cryptoloc Secure 2 Client is a powerful Electronic Document Signing platform that offers both flexibility and security. Available as a Microsoft Outlook Add-In, AWS API or fully customised solution that integrates with your ERP, CRM or other software.

Secure 2 Client is designed for businesses that want to fully digitalise their contract and agreement processes, without compromising security or risking a costly data breach. It works exactly the same as other Electronic Document Signing platforms with the addition of our patented triple-layer security solution which combines AES 256, RSA 4096 and RSA OAEP encryption into one unified technology.

Send fully encrypted documents straight from Microsoft Outlook using an Add In available from Microsoft App Source. Integrate it with your AWS solution using our simple API available from AWS Marketplace or have a fully customised and integrated solution designed to your exact specifications.

Our unique SMS verification service ensures that only the intended recipient can view and sign your document, eliminating the risk of costly data breach incidents caused by employee error. Generate fully admissible digital signature certificates that are accepted by most judiciaries worldwide, automatically in a matter of seconds.

Whatever your requirements, Cryptoloc Secure 2 Client offers both the security and flexibility that can help revolutionise your contract process and reduce your paper consumption and carbon footprint.
