Call & Contact Centres

Contact centres run on their phone systems. High call volumes, many extensions and out-of-hours operation make telephony exposure both more likely and more expensive when it is abused.

Why it matters here

The telephony risk in this sector

A contact centre's PBX or VoIP platform is business-critical and constantly in use, which makes both downtime and fraud materially more damaging than in a typical office. Large extension counts, agent turnover and integrations widen the attack surface, and out-of-hours fraud can run for longer before it is noticed.

  • Scale multiplies exposure

    Hundreds of extensions and frequent staff changes leave more accounts to compromise and more permissions to get wrong.

  • Out-of-hours fraud

    Quiet periods are exactly when fraudulent call spend accumulates unnoticed.

  • Card-by-phone scope

    Where agents take card details by phone, the telephony layer falls within PCI DSS scope and needs assessing accordingly.

  • Uptime is revenue

    An exposed, unpatched platform is a single point of failure for the whole operation.
