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.
