Security aspects

All communication between Cisco Webex applications and Cisco Webex Cloud occurs over encrypted channels. Cisco Webex uses the TLS 1.2 protocol and uses strong encryption (for example, AES 256).

For businesses that require a higher level of security, Cisco Webex also provides end-to-end encryption. With this option, Cisco Webex Cloud does not decrypt media streams. As in normal communications, it establishes a TLS channel for client-server communication.


It is important to analyze what each tool has to offer and what you want to achieve with it, whether it is for work, for more informal conversations between friends, or to hold conferences with many participants. Each of these tools has its advantages, but it is up to you to decide which is better for your company.

At THETA432 we understand the risks these tools entail and how important they are due to remote working. Companies must examine the tools their team will use to ensure all shared information is handled with appropriate security measures.

To help on this process and ensure secure communication, we created HELIOS, a new operating system, installed on Google phones that ensures that all communications are encrypted and not traceable. Whether you use your cell phone to video conference, text, or make calls, with HELIOS your conversations and information will always be safe. Contact us and see how you can benefit from it!
