Cyber-Ark's Inter-Business Vault is designed to protect confidential files in an extranet environment, where secure file sharing with remote offices and business partners is demanded. This requires a combination of secure file storage, encryption for files in transit, authentication and access control. There are many products that tackle these problems individually. For example, a virtual private network (VPN) encrypts files in transit, and access controls are built into modern operating systems. However, OS access controls can often be bypassed simply because unhardened operating systems are themselves so easy to compromise. Inter-Business Vault aims to address all of these problems by integrating a VPN, authenticated access controls and encrypted file storage in a very secure solution.
