2.27.0

New diagnostic codes have been added for Gatekeeper.

The following new risk engine factory models have been added:

• FACTORY_TI_RISK_ENGINE_1_5_BALANCED: A balance between false alarms and number of spoof attacks detected.
• FACTORY_TI_RISK_ENGINE_1_5_MIN_FALSE_ALARM: To minimize false alarms coming from anti-spoofing. Useful for cases where customers prefer a limited number of false alarms even if it means not catching some spoof attacks.
• FACTORY_TI_RISK_ENGINE_1_5_MAX_SPOOF_DETECTION: To be more aggressive in catching spoof attacks, even if it means more false alarms.

Notes:

• These factory models are trained for NVSL 11 and compatibility mode for older models, but aren’t intended to be used with convoprint or deviceprint.
• NSRL 1.4.2 has been upgraded to NSRL 1.5.2.

To allow the users to log in to Gatekeeper with their accounts of the organization tenant, the Entra ID tenant administrator can now consent to the applications once on behalf of the organization. Once done, tenant users are able to log in without issues.

Note: You don’t need to log in to access the Gatekeeper Onboarding page. This configuration is needed before the configuration of Entra ID and at that time you might not be able to log in.

The Download CSV option has been added to the Engagement page for the Japan region. Users can now download up to 10k rows in CSV format.

The Gatekeeper web portal shows the execution of multiple factors in one request with a dedicated numbering convention (1.1, 1.2, 1.3, …) to indicate that they’re executed from the same API request.

The following updates have been made to the Members page in Authorization Management:

• Added a user info pop-up.
• Added an option to show or search for users using external ID.
• Added a count displaying the number of all member types.
• Added self-refreshing cache for the logged-in user.

In the Members page of Authorization Management, the Refresh Cache option from groups entity has been removed.

The Web Agent Console UI now supports:

• Theme - Dark and light themes are now available.
• Layout - The layout has been updated to include a mini WAC layout.

The Log in page replaces the reference to Azure AD with Entra ID.

A new API AnalyzeAudio, also known as combo API, is available that runs multiple factors in one request to optimize the processing time.

WAV header duration value is unreliable when fetching media through GetMedia API, GetMediaUnmasked API, or through /media URL obtained from the PublishMedia or PublishUnmaskedMedia API.

Use duration provided by the GetMediaInfo API instead of relying on the duration of the WAV header.

In the Web Agent Console miniature view, language prompts aren’t localized to match the miniature view.

In Web Agent Console, some Dutch prompts aren’t localized, and they default to the English locale.

Any NVSL frameworks at 16 kHz don’t work, as Gatekeeper doesn’t support 16 kHz audio yet:

• FACTORY_TI_16kHz_10
• FACTORY_TI_16kHz_9
• FACTORY_TI_16kHz_8_2
• FACTORY_TI_16kHz_8
• FACTORY_TI_16kHz_7_2

Rarely it may happen that a post call session is isolated in a separate engagement and not aggregated with the other live sessions.

DEMO and Bootstrap risk engine calibration models might not work properly and they show poor accuracy. Use these models only for non-production use.

Gatekeeper Web administrator applications don’t officially support Private Browsing Mode. Without them, the Console may display an authorization error. This isn’t required for agents authorized for a single scope.

The autocomplete for first name and last name doesn’t work when using special character, such as ‘@’ or ‘_’.

Web Admin Portal has a time zone selection issue related to browser updates.

Kibana Dashboard – The Generate PDF feature doesn’t work when Optimize for Printing is enabled.

A Clustering or Backwards Search action may time out due to the memory required for media collection exceeding configured limits. This is likely due to a collected engagement containing more than an expected number of sessions but could have another cause.

Clustering and Backward Search have the following limitations:

• No estimations available for media collection.
• Clustering and Backwards Search require manual scaling.

Audio streaming for transcription is limited to one realtime (this value isn’t configurable).

For Stereo audio, the redacted overlay interval applies on both channels in the audio viewer.

Realtime redaction isn’t supported when Transcribe API is used.
