Create spaces with the right people

Webex Teams brings messaging, meetings, and calling together in one place from the spaces and teams you create with other people. You can also invite people outside your organization, such as vendors and customers, to collaborate with you. Because it’s so easy to bring people together, think about how you want to control who’s in the space.

The Webex Teams app uses advanced cryptographic algorithms to safeguard content you share and send. The only people who can view files and messages in a space are those invited to that space or authorized individuals.

Moderate spaces

You can add extra security by adding moderators for teams and spaces with sensitive information. Moderators can control who has access to the space, who can add others, who sees the information that's shared and can delete files and messages.


Free Webex Teams users can create Teams and add moderators to the General space, but can’t add moderators to regular spaces.

Check if there are people outside your organization

Check if there are external users in a space before you send messages, so you don't accidentally share confidential information.

If spaces include people from outside your company, you'll see areas in the spaces highlighted, like the border, background, the icon in the message area, and their email addresses.

Join and host secure meetings

Depending on whether you have a Webex Meetings and Webex Teams account, or Webex Teams account only, there are several ways you can secure meetings - lock meetings, restrict access.

Check who's in the meeting

When you schedule a space meeting, it includes everyone in your space at a specified date and time, whether it's a space with one or more people. Check who is in the space before you schedule a meeting. You can also find out who joined your meeting.

Lock your meeting


Available with a Webex Meetings enabled account.

You can lock meetings after you start it from Webex Teams. If you don't lock your meeting, anyone who has the meeting link can join it. No one can enter the room until you unlock it or let them in.

Remove uninvited people from the meeting


Available with a Webex Meetings enabled account.

If someone who wasn't invited join's a meeting, you can expel them from a meeting at any time.

Things site administrators can do

Site administrators have the option to set up features in their organization that use existing security policies:

Synchronize employee directories

Synchronize employee directories with Webex Teams. Automatically recognizes when someone has left a company, so former employees won't be able to access company data using Webex Teams.

Enable single sign-on (SSO)

Single sign-on (SSO) which uses one unique identifier to give people in your organization access to all enterprise applications. Administrators can configure SSO for Cisco Webex applications.

Enforce password security standards

When you've configured SSO, you can also ensure that Webex Teams requires passwords and authentication. The Webex Teams app supports identity providers that use Security Assertion Markup Language (SAML) 2.0 and Open Authorization (OAuth) 2.0 protocols.

The Webex Teams app encrypts messages, files, and names of spaces on your device before sending them to the cloud. When the data arrives at our servers, it's already encrypted. It's processed and stored until it's decrypted on your device. However, the app can’t provide strong encryption for messages and files linked to in-app automation tools like bots or integrations or to Adobe Acrobat PDF and Microsoft Word documents sent to spaces from Box.

We use Secure Hypertext Transfer Protocol (HTTPS) to encrypt data while in transit between your device and our servers, which protects the identities of both senders and receivers.

Our strong encryption uses Advanced Encryption Standard (AES) 128, AES256, Secure Hash Algorithm (SHA) 1, SHA256, and RSA.

For audio, video, and screen sharing, we encrypt shared content using the Secure Real-Time Transport Protocol (SRTP).
