Custocy announces a new advanced Command & Control detection engine
May 12, 2025
Cyber threats - Cybersecurity - Artificial Intelligence - Security network
Custocy, the french expert in artificial intelligence for network threat detection, continues to innovate and unveils the new version of its sovereign NDR solution. This third release introduces major technological advancements, including a new AI engine specifically designed to detect Command & Control (C2) communications. It also enhances targeted response capabilities through compatibility with leading cybersecurity players such as Fortinet and Palo Alto Networks.
The only french AI-powered NDR
Built on an artificial intelligence engine, Custocy’s solution continuously monitors IT networks to detect malicious activity as early as possible, and enable a quick response. It is capable of analysing large volumes of network traffic data to detect unusual behaviour, including the weakest signals that would escape traditional security tools. Security teams are alerted in real time, allowing them to respond before an attack occurs.
100% Made in France, Custocy’s NDR solution stands out for its ability to combine cutting-edge AI with operational performance in the face of increasingly stealthy and complex threats.
Main new features in Custocy Version 3
- Two new detection engines designed to address sophisticated threats: targeting Command & Control activities and data exfiltration using obfuscation techniques,
- Enhanced behavioural analysis and new training datasets for more precise detection and reduced false positives,
- Optimised console performance for smoother investigations,
- New dashboard offering instant insight into attacks, with the ability to zoom in on specific assets to aid investigation,
- Automated whitelisting suggestions to accelerate solution deployment,
- Seamless integration with existing cybersecurity ecosystems via REST APIs,
- Improved data collection for better classification performance and enhanced threat detection,
- Configurable automated response: define response rules and set up automatic actions according to various incident types for immediate remediation.
An alternative to anglo-saxon solutions
Built upon high-performance technology backed by nearly €10 million in investment, Custocy positions itself as a credible sovereign alternative to established market solutions such as Darktrace and Vectra AI. This new version further strengthens its ability to adapt to the most advanced attack tactics, while improving detection accuracy and analyst experience.
Custocy V3 is now available through its network of partners.
