End-to-end encryption

What is end-to-end encryption?

End-to-end encryption is a security method that protects communications so that only the sender and the intended recipient can access the content. Data is transformed into an unreadable format while traveling across the network, preventing third parties—including service providers—from reading it.

Why is it important for businesses?

Because it ensures the confidentiality of sensitive data such as financial information, intellectual property, or critical internal communications. With end-to-end encryption, companies reduce the risk of espionage, data breaches, and unauthorized access, even if networks or intermediate servers are compromised.

Where is it used in practice?

It is widely used in secure messaging apps, email services, videoconferencing, and enterprise collaboration solutions. It is also common in regulated sectors such as banking, healthcare, and public administration, where data protection is a top priority.
