Communications Security
Toll-fraud protection, encrypted voice, PCI-compliant recording and authentication controls for UK business telephony.
About communications security
Voice systems are now a primary target for fraud. Toll fraud, premium-rate dial-out abuse and credential stuffing of SIP accounts cost UK businesses tens of millions a year. Telappliant communications security wraps your telephony in the same disciplines we apply to IT and data security.
Every Telappliant voice service ships with destination whitelists, daily spend caps, premium-rate barring, geographic restrictions, and 24/7 anomaly detection across our network. Calls are encrypted in transit using TLS and SRTP, and SIP credentials are never stored on user devices.
Call recording is handled to PCI-DSS standards. Card-data sections can be paused automatically or stripped from the recording, and recordings are encrypted at rest with role-based access controls and tamper-evident audit logs.
We integrate with your identity provider so multi-factor authentication, conditional access and single sign-on apply to phone system administration and to softphone clients. Lost devices can be revoked instantly.
If you operate in regulated sectors - financial services, healthcare, legal - we will help you map our controls to FCA, ICO and Cyber Essentials requirements and provide the evidence you need for audits and customer due-diligence questionnaires.
