Horizon3 launches AI cybersecurity platform in Spain and Portugal
Horizon3, a cybersecurity company based in San Francisco, has started operating in Spain and Portugal.
Its platform, NodeZero, uses artificial intelligence to test customers’ real computer systems for weaknesses.
The tests aim to show how an intruder could use weak credentials or mistaken settings to reach important systems.
The launch comes as Spanish authorities warn that AI is being used in real cyberattacks, and companies face pressure to keep up with threats that can move quickly.
Horizon3 says its platform draws on data from about 330,000 penetration tests across more than 7,000 customers.
It plans to focus on large organizations and work through technology distributor Exclusive Networks and its partners.
The company hopes to match its wider growth in the new markets, but has not given a timetable or target for its expansion.
Horizon3 has begun operating in Spain and Portugal with a platform that uses artificial intelligence to simulate cyberattacks and find vulnerabilities.
The company is targeting large organisations through distributor Exclusive Networks and its network of integrators and managed service providers.
Its NodeZero platform continuously tests customers’ real environments to show how attackers could exploit weak credentials and misconfigurations.
Horizon3 says it has conducted nearly 330,000 penetration tests across more than 7,000 customers.
