Lifesize® Security for Cloud-based Service and Devices


Security concerns are a big reason companies hesitate using cloud-based services for any application. Video conferencing is no exception. At Lifesize, we understand the importance of security and privacy. We built the Lifesize cloud-based service to provide customers with a secure experience from the meeting room to the office and on the go.



All Lifesize cloud-based calling capacity is hosted on dedicated machines within highly-secure IBM Cloud data centers. Account administration, software update delivery, and streaming and recording are hosted in Amazon Web Services data centers. Lifesize uses best-of-breed data centers with independent third-party security and privacy certifications to ensure the most secure and reliable foundation possible for our customers.

Compliance certifications for our data center partners can be found here:

Lifesize maintains staff dedicated to security and privacy as their primary and sole job function.


The Lifesize cloud-based solution room systems and client software provide secure and encrypted1 video, audio, presentation (media) and call setup (signaling) in every call end-to-end. Media uses different ports for each call and is encrypted via SRTP/AES-128 (Secure RTP and Advanced Encryption Standard). Signaling uses a non-standard port and is secured via SIP+TLS (Transport Layer Security). Every caller’s connection is encrypted using single-use encryption keys.

Lifesize also provides WebRTC clients, either natively in the browser or via plugin. Encryption is a mandatory component of WebRTC and applies to both signaling (via DTLS) and media (via SRTP/AES-128).

Third-party H.323 systems will join in a secure fashion if configured for H.235 encryption.


The Lifesize cloud-based solution offers a dial-in audio conferencing capability delivered via Twilio and Voxbone. These two leading providers deliver PSTN to VoIP connectivity with dedicate routes directly to the Lifesize infrastructure. Audio calls originating from the PSTN dialed towards the Lifesize cloud-based service will remain unencrypted, similar to other voice conferencing services.


Lifesize offers several features to keep your meetings secure:

  • Passcodes can be used to secure your meetings
  • Meetings can be created for one time events, then deleted
  • Call escalation allows you to actively accept or reject new participants into a meeting
  • During a meeting, a moderator can remove participants from a call
  • During a meeting, a moderator may mute all participants
  • During a meeting, a user may mute their own audio and/or video

Lifesize supports single sign-on (SSO). SSO allows you to extend your own password retention, complexity and controls consistently to Lifesize. SSO also allows you to control which users have access to your Lifesize cloud-based subscription, and who does not. More importantly, with SSO, Lifesize authentication will occur directly between your users and your identity provider (IdP).

To provide SSO, Lifesize integrates with your IdP via SAML 2.0, which is the recognized standard for secure authentication to cloud services. Lifesize has validated interoperability with many top tier IdPs, including Microsoft ADFS, Azure AD, OneLogin, Ping Identity and Okta.

If you choose not to use SSO, secure and private alternatives are available for local user authentication and management. In this scenario, the connection between the Lifesize cloud-based apps and service is authenticated through https and registrations are secured via TLS. Administrators can grant or revoke user or room system access at any time.

Our architecture allows you to keep your Lifesize room systems and client software safely behind your firewall and manages firewall traversal through our global calling nodes. Lifesize room systems and client software do not require any firewall ports to be opened inbound from the Internet. There's also no longer a need for static public IP addressing or complicated static NAT and port-forwarding firewall configurations. This allows you to maintain your existing perimeter posture and protects your users and devices from SIP and H.323 nuisance calls that are common on the open Internet.

Lifesize only makes use of outbound TCP/UDP connections for call set up and media. These TCP/UDP connections are always initiated by the Lifesize room system or client software in order to establish pinholes and dynamic port address translations. These connections are always directed to one of our global calling nodes on a specific list of published host IP addresses allowing for tightly crafted firewall rules.


Information about opening ports and configuring your network is available on our website.


Lifesize maintains a Privacy Shield certification issued by the US Department of Commerce on November 3, 2016. Our data center partners maintain the same.

  • Review our publicly available Privacy Policy. 
  • Review our statement clarifying Lifesize access to customer environments.

Video communication data is transient in nature and encrypted in flight. Lifesize does not record, capture or store any video conference media (audio, video or presentation). We do maintain basic metadata of each call so that customer administrators can access usage reports and information. Similarly, server logging is retained for the purposes of technical support engagements and troubleshooting. This data does not include any media.


As a part of consuming our service offering, Lifesize stores only the basic information below for each of our customers’ user accounts. Should you choose to leave the service, this information will be permanently deleted 180 days following the end of your contract.


  • Email address (which is also your username)
  • Password (for non-SSO accounts only)
  • First name, last name
  • Display name
  • Telephone
  • Address
  • Company

Users and Superusers

  • Display name
  • Email address (which is also your username)
  • Password (for non-SSO accounts only)

Lifesize offers streaming and recording services as an additional option for our customers. Recorded calls are stored in secure Amazon Web Services facilities. Access to view recordings may be globally restricted to users within your organization by your administrator.

  • Lifesize Record and Share is available2 to subscribers of the Lifesize cloud-based service. Record and Share is disabled by default and must be purposefully enabled by an administrator before users are able to record any calls.
  • Content distribution may be restricted to only your own organization.
  • Lifesize Record and Share is encrypted using AES-128 for data in-flight (recording and playback) and AES-256 for data-at-rest (storage).
  • Lifesize Record and Share is hosted on Amazon Web Services (AWS), which is designed for security across all geographies and verticals. Learn more about AWS Security.
  • Initiation of recordings requires manual intervention whereby a user of the Lifesize cloud-based service must activate the feature to record the conference session.
  • An on-screen notification will be displayed to all video participants taking part in the conference to notify users that the call is being recorded.

Lifesize chat is hosted on Amazon Web Services (AWS), which is designed for security across all geographies and verticals. Learn more about AWS Security.


We leverage a third-party, PCI-certified partner for direct sales and our Lifesize partners for channel sales; therefore, no user billing information is stored in our system.

Service Optimization and Availability

The Lifesize cloud-based service is operated in secure data centers in North America, Europe, Oceania and Asia, ensuring redundancy and failover. Lifesize calling capacity is hosted exclusively in IBM Cloud data centers. Lifesize room systems and client software will automatically register with the closest and least-busy cloud node in order to minimize public Internet traversal for your users regardless of their location. Calls between these users will leverage IBM Cloud’s private network, rather than the Internet, to minimize latency and maximize quality.

In case of disruption, your Lifesize room systems and client software users will be routed to another available server, in some cases without disconnecting a live call. Our systems are backed up, ensuring that your configurations are protected and up to date.
