Comprehensive analysis

Invosys Call Shield identifies fraudulent or spam calls based on their location, call source, number presentation and volume of concurrent calls made. We can extract and analyse the metadata of every single phone call, profiling it and establishing whether it has all the typical characteristics of a fraudulent call or not.

Customisable pathways

If a call is detected as suspicious, we can route the call to an agent, flag it or drop it. We’ll work with you to define a workflow around handling fraudulent calls and ensure you have proper processes in place.

Powered by AI

As fraudsters are always adapting their methods to try and slip through the net, we’ve integrated AI and machine learning into Call Shield so that it’s constantly learning from the fraudulent calls it identifies. Machine learning allows us to pick up on any changes in fraud patterns immediately, ensuring criminals are blocked at every instance.

Unrivalled database

We have several exclusive partnerships with industry bodies that provide access to an extensive database of known telephone numbers associated with fraud. This database is one of the most comprehensive available and is updated in real-time to ensure we’re working off the most up-to-date information.
