Discover in this article why choosing cloud-hosted solutions with end-to-end encryption is essential for your security

Both public and private organisations are storing more and more data in the Cloud. This gives them the flexibility they need to collaborate effectively and seamlessly but also requires them to secure data and file sharing. Choosing Cloud solutions that implement end-to-end encryption allows them to meet these two requirements. Let’s see how.

What is end-to-end encryption?

Definition of end-to-end encryption

End-to-end encryption is a technical process designed to protect data privacy, by using cryptographic keys and encryption protocols. Information exchanged is encrypted and readable only by its sender and recipient, who are the only ones with access to encryption keys. 

End-to-end encryption can:

• Maintain data confidentiality
• Protect against data breaches
• Reduce the risk of espionage
• Ensure data integrity during transfers

How is end-to-end encryption different from other data protection methods? 

Encryption of data at rest and encryption of data in transit are basic measures. However, they are not satisfactory as long as the server has access to the data. In the event of an attack on the server, data may be compromised. With end-to-end encryption, the server has no access to the data, which remains protected in the event of an attack.

Deploying end-to-end encryption is a technical task that does not tolerate approximation due to the stakes involved. Customers looking for Cloud-hosted solutions generally don’t want to manage their data security on their own, and so prefer to turn to secure, end-to-end encrypted Cloud-hosted solutions, such as those offered by ERCOM.

End-to-end encryption, a response to the security challenges posed by Cloud solutions

While the use of Cloud-hosted solutions offers many advantages (flexibility, seamlessness, remote access, etc.), it also raises questions about data security, privacy, and sovereignty, since the data is entrusted to third-party vendors. End-to-end encryption is considered one of the most effective security measures for protecting data exchanged via Cloud communications (videoconferencing, messaging, file-sharing services, etc.). No third party (Internet service provider, monitoring program, etc.) can decrypt the data in transit. Even if the data is intercepted, it cannot be read (decrypted) without the encryption key.

Example of ERCOM solutions with end-to-end encryption in the Cloud

To meet the challenges of secure communications, ERCOM offers Cloud-hosted solutions with end-to-end encryption for even greater security. Cryptobox and Citadel are two examples of end-to-end encrypted solutions that can be hosted in the Cloud.

Cryptobox, the secure file-sharing and collaboration solution

End-to-end encryption is an effective process but can be complex to implement. This is precisely why certain collaboration and file transfer solutions integrate this process directly, so customers don’t have to implement end-to-end encryption by themselves. Cryptobox, for example, is a collaboration and file transfer solution with end-to-end encryption for user data. Documents are protected and available in any environment and any device, even when shared with external partners.

Citadel Team, the secure messaging, audio & video conferencing solution

Citadel Team is a complete platform for audio collaboration, videoconferencing, and secure messaging, with optional end-to-end encryption. Messages, documents, multimedia files, and calls can be encrypted when required.

End-to-end encryption is now considered an indispensable process for securing Cloud-hosted solutions. It combines the power and seamlessness of Cloud solutions with data security requirements.
