CoSign Central is an enterprise grade turnkey solution which allows any number of employees to sign any document within any business process within the company. It includes the highly secured CoSign Central appliance (black box) which is installed within the organisation’s own computing infrastructure, and provides the necessary digital signing services to all users, applications, and business processes across the organization.
The CoSign Client for Windows includes desktop plug-in’s to MS Office and Adobe PDF. Alternatively, you can install internally the CoSign Web Application to allow users to sign documents from any device without having to install any software. You can also use the CoSign Mobile native apps (iOS/Android) to sign documents “on the go”.
CoSign digital signatures are 100% compliant with the PKI standard, which is the only signature standard published, maintained and accepted by the US Federal Government, EU Governments, the European Telecommunications Standards Institute (ETSI), and independent bodies such as ISO, OASIS, IETF, W3C, etc.
The vast majority of the world’s countries already enacted laws which address Digital Signature related issues, based on the guidelines and models published by UNCITRAL (United Nations Commission on International Trade Law). CoSign creates legally enforceable digital signatures in accordance with all legislations modeled on UNCITAL.
CoSign is a certified standard solution, and offers enterprise grade hardware features such as High Availability and Load Balancing options.
Key practical benefits
Digital Signatures infrastructure which is sufficiently secured to be trusted, and, together with appropriate standard operating procedures, can meet any regulatory requirement for document signing, worldwide.
Compatibility with all/any “PKI-aware” system such as MS Office, Adobe PDF, AutoCAD, etc.
CoSign Signatures can be fully verified and validated by any external party without having to connect to the CoSign appliance or use any CoSign service.
Guaranteed privacy – the entire signing process is accomplished internally, content is never exposed to any 3rd party. Even if deployed in the Cloud, the document content itself is never transmitted or exposed; only the document “fingerprint” is sent to the CoSign Central Appliance.
Low risk, no vendor tie-in. The signatures produced by CoSign are valid and verifiable even in the event CoSign is no longer used within the organization.
User management & authentication options
Automatic synchronization with Active Directory (or any LDAP).
Active Directory Federation Services (ADFS) and claims-based authentication using SAML tokens.
Directory independent mode:
Manual user management using CoSign Admin Client for Windows.
Bulk upload / manual sync with external SQL user directories.
Programmatically using CoSign API.
Support for 2-Factor Authentication 3rd party products, such as One-Time-Password (OTP), Biometric and Smartcard/USB Token authentication products (RSA, Vasco, SafeNet, VeriSign VIP, Cidway, Digital Persona, Saflink).
Support for one-time external signers authenticated by email and one-time SMS tokens.
Certification
CoSign Central runs internal Certification Authority (CA) software. In most cases, the CoSign secured appliance acts as the internal CA of the organization, issuing (and automatically renewing) end-user certificates.
As a turnkey solution, CoSign is inclusive of all the components and infrastructure required to implement digital signing:
CoSign securely (and automatically) generates the Private/Public key pair for each user, and stores these keys in its encrypted internal database. The keys are non-extractable. CoSign is certified to provide the same key protection level as found in smartcards.
CoSign issues X509 Digital Certificate for each user, and its internal CA signs these certificates as per the PKI standard. The user certificates are also stored securely within the CoSign appliance.
The Root Certificate of CoSign internal CA can be extracted and published on CoSign Nation (https://cn.arx.com) and made available to external parties to download so they can automatically trust any signature generated by any of the organizations’ CoSign users.
CoSign can also work with externally issued certificates, instead of using its own internal CA. CoSign provide interfaces for commercial CAs such as Comodo, Quovadis, or operate as a sub-ordinate internal CA under the root of GlobalSign, and Netrust.
