RF spectrum monitoring and drone detection that protects what matters
Cevranta senses the radio spectrum, tells known signals from unknown ones, and locates the source in seconds. Governments, infrastructure operators and security teams use one shared picture to decide and act.

The border begins in the spectrum. Every radio, every drone link, every jammer shares one contested space. This system listens across the whole of it, in real time. Known signals are recognised instantly. Modified and unknown signals are flagged before anyone has to reverse-engineer them. Detection becomes location, and location becomes action, in seconds, at the edge, even when the network is degraded. Every node feeds one shared picture to command. Open, sovereign, and under national control. We work with military and intelligence agencies, homeland security agencies, border protection authorities, police organisations, and operators of critical national infrastructure. Cevranta Technologies. Understand the spectrum. Dominate the battlespace.
What we do
Drones, jammers and tracking devices all rely on radio. We make that radio visible.
Classify every signal
AI separates known signals from modified and unknown ones, so analysts see what needs attention first.
Locate, then decide
Direction finding places the source on the map. Responses follow agreed rules and need operator approval.
How it works
From detection to decision, in one connected system
One national picture
Sensors share what they hear
Each sensor reports to a common picture. A drone or an unknown link crossing a boundary is tracked as it moves, with alerts when it breaches a protected area.
- Networked sensors, from the tactical edge to national command
- Geofenced alerts for sites, borders and routes
Signal intelligence
AI that sees every signal
The AI engine decodes more than 100 protocols and sorts signals into known, modified and unknown. Unknown signals are tracked without waiting for an analyst to take them apart.
- Known, modified and unknown classification
- Continuous recording to open formats
Air and sea
Drones and vessels, in one view
Coastal and port approaches are watched for drones, vessels and unknown links. When a link is detected, the sensors work together to locate it.
- Known and unknown links shown separately
- Located using several sensors at once
Direction finding
Know exactly where it is
Angle-of-arrival and time-difference methods turn a detection into a position in two or three dimensions. Operators get a bearing they can act on.
- AoA and TDOA geolocation
- 2D and 3D coverage
Sectors
Built for the people who protect borders, infrastructure and public life
One platform for government and defence, infrastructure operators, commercial security teams and close protection.
Government and defence
Defence and national security
Border and coastal security, counter-drone protection, signals intelligence and spectrum management.
Critical infrastructure
Critical national infrastructure
Energy, transport, ports, airports and communications sites protected with one shared picture.
Commercial and public safety

Early warning of drones and covert transmitters around people who may be targeted.
Use cases
Eleven ways Cevranta keeps people and places safer
Border and coastal security
Detect unauthorised radio activity, drones and vessels on land and sea approaches.
Counter-drone protection
Find drone control links and flag unknown ones before they reach a site or a force.
Convoy and location-tracking protection
Spot tracking transmitters and hostile radio activity around moving convoys, before it becomes an ambush.
Drone-delivered threats
Detect and locate drones used for surveillance or attack against people and sites.
Airports and ports
Monitor airfields, harbours and their approaches for rogue drones and interference.
Telecoms and mobile operators
Identify jammers and unauthorised transmitters that affect networks and licensed spectrum.
Critical national infrastructure
Give energy, transport and communications operators a shared picture of radio threats.
Signals intelligence
Capture, classify and analyse signals for intelligence teams, in open formats.
Spectrum management
See who is using the spectrum, where and when, and spot what should not be there.
Law enforcement and specialised security
Protect events and sensitive sites with early warning of drones and covert devices.
Close protection and VIP security
Warn protection teams of drones and covert transmitters near the people they protect.
Safety and control
Security that stays accountable
The places Cevranta protects are the ones people rely on every day: airports, ports, power, communications and public events.
- People make the decisions
- Detection, classification and location are automated. Any response needs operator authorisation.
- Rules agreed in advance
- Responses follow rules and confidence levels that your organisation sets, so actions are consistent and can be reviewed.
- Under national control
- Deploy on-premise, air-gapped, in a private cloud or as a hybrid. Your data stays where you decide.
- Open by design
- Standard interfaces and data formats keep you in control of your own systems and records.
Platform

Questions
Frequently asked questions
What is RF spectrum monitoring?
RF spectrum monitoring is the continuous detection and analysis of radio signals across a range of frequencies. It shows who is transmitting, where, and whether the signal is expected. Cevranta senses from 20 MHz to 18 GHz.
How does drone detection work without cameras or radar?
Most drones are controlled over a radio link. Cevranta detects and classifies those links, then uses direction finding to locate the transmitter. It complements radar and cameras rather than replacing them.
What happens when a signal is unknown or has been modified?
The AI engine classifies signals as known, modified or unknown. Unknown and modified signals are flagged and tracked automatically so analysts do not have to reverse-engineer them before acting.
Can Cevranta run without an internet connection?
Yes. Sensing and analysis work at the edge, including when the network is degraded. The platform can be deployed on-premise, air-gapped, in a private cloud or as a hybrid, under national control.
Who does Cevranta work with?
Military and intelligence agencies, homeland security agencies, border protection authorities, police organisations and operators of critical national infrastructure.
Who decides what action is taken?
People do. Detection, classification and location are automated, but responses follow rules and confidence levels set in advance and need operator authorisation.
