Q: How is this technology different from solutions that claim end-to-end encryption?
End-to-end encryption is not difficult to achieve using a secure encryption algorithm if a sender and recipient(s)
securely share passwords or their PGP keys. However, neither of these are easy to share and keep track of, and do
not provide policy-based controls like time limits or revocation as needed. VoltShare does not use passwords for
recipients to decrypt their shared content — just a piece of information the sender already knows — e.g. recipient’s
email address. In addition, VoltShare provides increased security and compliance through a broad set of policy-based
controls and revocation capabilities, as well as detailed logs and analysis.
Q: Why should I use VoltShare if my cloud service provider (e.g. Dropbox or Office 365) or collaboration tools (e.g. Slack or Teams) are already encrypting all my data?
VoltShare does not replace any cloud storage or collaboration services. It helps you more securely store or
transfer data so you’re not relying solely on these cloud providers for the privacy and security of your data
— essentially providing “layered security”. If these cloud services were ever compromised (externally or from within)
or forced to hand over data to a government agency, your data will not be compromised as it is independently encrypted
on top of your cloud provider’s underlying security service.
Q: What’s the difference between the free and paid versions of VoltShare?
The free version of VoltShare includes all the functionality required for data encryption, decryption and policy
enforcement - using the app or the APIs+SDK. The paid version includes additional functionality for enterprise-level
security, compliance audits and governance — including logs for encrypt/decrypt activity + associated policy-based
denials, audit logs, policy revocation or overrides, and single sign-on. The paid version also increases the rate
limits on the APIs.
Q: How do I install VoltShare?
VoltShare can be easily downloaded from here and installed on
your personal computing device. Upon installation, the application will ask you to provide your existing Volterra
account credentials or sign-up with Volterra using your existing google, facebook, or github account.
Q: Can Volterra’s infrastructure, SaaS platform or teams get to see my data — either in clear or encrypted form?
No, VoltShare is unique in that Volterra’s cloud infrastructure and SaaS platform never see the actual content
shared or the encryption key that the sender’s VoltShare client app randomly generates to protect the data.
Everything remains on the sender’s and recipients’ local machines during the encryption and decryption process.
Q: How does Volterra secure my data without transferring any data to its servers?
The VoltShare client software on your computing device encrypts data using the well-known cryptographic algorithms
AES-GCM (256-bit) and RSA (2048-bit). The encryption keys themselves are double-protected by other cryptographic
keys that are managed by a state-of-the-art key management system in Volterra’s SaaS platform and cloud infrastructure.
