Voice security & antifraud

Reduce the risk of unauthorized calls, credential theft and fraudulent spending with controls across several layers.

Prevent unauthorized calls and spoofing
Detect fraudulent schemes in real-time
Control voice service expenditures

IMPLEMENTATION

Two ways to build.

The same business task. Infrastructure that fits your data policy, team and budget.

01 / ON-PREMISES

Own hardware

Implement network restrictions, access controls and voice traffic monitoring.

How we implement it

Configure an SBC, segmentation, allowed destinations and limits.
Enable TLS/SRTP on supported segments, role-based access and key rotation.
Connect logs to SIEM and rehearse incident response.

Technology options: SBC/OpenSIPS, network segmentation, TLS/SRTP where both ends support them, role-based access and SIEM.
Data & dependencies: Rules and logs can stay local. A carrier sees necessary external-call data; encryption is checked on each segment.
Budget components: Assessment, SBC, SIEM integration and response procedures; then updates, alert review and team training.
Operations & support: The support agreement assigns ownership of hardware, OS, applications, updates and incident response. Recovery is tested before launch.

02 / API PLATFORMS

International APIs

Combine provider controls with custom rules and specialist analysis where needed.

How we implement it

Select provider and configure API integration
Implement signed webhooks and API rate limits
Set up fraud detection rules and alerts

Technology options: Pindrop (optional), API gateways, webhooks, regional cloud services
Data & dependencies: External analysis requires an agreed data map. Biometrics are not enabled by default; legal basis and specialist service features are assessed separately.
Budget components: Limits and audit configuration; then analysis volume, storage, specialist service licences and incident response.
Operations & support: The provider operates its platform; the project team maintains integrations, quotas and API changes within the agreed scope. Support coverage is defined by contract.

Discuss this option ↗

Technology choices are confirmed after an assessment. Platform names indicate implementation options, not partnership status. Calls to the public telephone network require a carrier in either model.

BEFORE LAUNCH

Agree what success looks like.

Our integration process ↗

01
Test destination, spending and call-rate restrictions.
02
Exercise webhook signatures, permissions and secret rotation.
03
Evaluate false positives; synthetic-voice detection is a risk signal, not proof of identity.
