Signaling firewall
Blocks location tracking, interception and SIM-swap probes across SS7 and Diameter.
What it is
Security and SIM lifecycle, together
Signaling networks were designed for trust, and attackers exploit that to track subscribers, intercept messages and commit fraud. Our signaling firewall inspects SS7 and Diameter traffic in real time and blocks what should never reach the core.
On the device side, eSIM management and SIM-OTA let you provision, update and switch subscriber profiles remotely, with no shop visit and no plastic.
- SS7 & DiameterReal-time inspection
- Anti-spamSmishing filtered at the edge
- eSIM & OTARemote SIM lifecycle
What you get
Four layers of control
Protection for the network and flexibility for every subscriber.
Anti-spam
Filters smishing and spoofed senders without delaying legitimate traffic.
eSIM management
Download, activate and switch profiles on phones, wearables and IoT devices.
SIM-OTA
Update SIM settings and applets over the air across the whole base.
How it works
From audit to always-on protection
- 01
Audit
We assess signaling exposure and current SIM operations.
- 02
Deploy
Firewall rules and eSIM platforms are installed.
- 03
Tune
Rules are refined against real traffic to avoid false positives.
- 04
Monitor
Threats and profile events are reported continuously.
Frequently Asked Questions
What attacks does a signaling firewall stop?
Location tracking, SMS interception, call redirection and SIM-swap probes that abuse SS7 and Diameter.
Will filtering slow down traffic?
No. Inspection happens in real time with negligible added latency.
Can eSIM work for IoT fleets?
Yes. Profiles can be managed remotely across large numbers of devices.
Do you support physical SIMs too?
Yes. SIM-OTA updates physical SIMs over the air alongside eSIM management.
