Catch Identity Fraud at the Source
SIM swap and identity fraud exploit the signalling layer of the network, where a stolen identity becomes a stolen account. PertSol's solution draws on SS7 and SIGTRAN probe-based monitoring to profile activity at that layer — detecting the patterns that signal fraudulent identity changes as they happen. Operators and agencies move from discovering fraud after the loss to recognising it at the point of compromise, where it can still be stopped.

The Obstacles We Were Up Against
Fraud surfaced only after the loss
By the time a SIM swap was discovered, the damage was usually done — accounts drained, identities hijacked, victims left to recover. The fraudulent activity happened at the signalling layer of the network, invisible to systems watching only at the surface. Without visibility into that layer, operators and agencies were left investigating completed fraud rather than detecting it as it formed.
Signalling activity went unmonitored
Patterns were hard to detect in time

How We Address This
SS7 & SIGTRAN Monitoring
PertSol uses probe-based monitoring at the SS7 and SIGTRAN signalling layer, bringing visibility to the exact level of the network where SIM swap and identity fraud take place.
Probe-Based Monitoring
Network signalling is monitored at the SS7/SIGTRAN layer.
Signalling Visibility
Activity at the identity layer is brought into view.
Real-Time Capture
Signalling activity is observed as it occurs.
Identity Profiling
Activity at the signalling layer is profiled to build a picture of normal identity behaviour, so that the changes signalling a fraudulent swap can be recognised against it.
Identity Profiling
Signalling activity is profiled to establish normal behaviour.
Anomaly Detection
Deviations from normal patterns are flagged for review.
Metadata Correlation
Signalling records are cross-referenced for context.
Pattern Detection
Pattern analysis distinguishes the signalling behaviour of a fraudulent identity change from a legitimate one, helping operators and agencies act while the swap is still in progress.
Pattern Identification
Fraud-indicative signalling patterns are surfaced.
Anomaly Detection
Unusual identity activity is flagged in real time.
Alerting
Defined triggers raise alerts on suspected fraud.
Real-Time Response
Detection at the point of compromise gives operators and agencies the timing to intervene before a swap completes, turning a fraud they once discovered afterward into one they can stop.
Real-Time Detection
Fraudulent activity is identified as it occurs.
Alerting
Suspected fraud raises immediate alerts for response.
Link Analysis
Connected fraudulent activity is mapped for investigators.

Outcomes Beyond Expectations
By monitoring the SS7 and SIGTRAN signalling layer and profiling identity activity, PertSol helps operators and agencies recognise SIM swap and identity fraud as it happens — shifting from investigating completed fraud to detecting it where it can still be prevented.
Visibility Where Fraud Lives
Probe-based monitoring brings the signalling layer where SIM swap occurs into view.
Fraud Recognised in Time
Identity profiling and pattern detection surface fraudulent changes as they form.
From Recovery to Prevention
Real-time detection shifts agencies from investigating losses to stopping them.
Connected Fraud Exposed
Link analysis maps related fraudulent activity into a single investigative picture.
