About the service

Cyber Network Defense (CND)

Your network is the new target. Defend traffic, access and data with real-time inspection, access control and perimeter protection — before a flaw becomes an incident.

Technologies

In practice, CND combines technologies such as

IDS / IPSThey identify and neutralize suspicious or unauthorized movements.
Firewall / NGFWTraffic control with deep packet inspection, blocking of malicious applications and network segmentation.
NAC — Network Access ControlEnsures that only authorized devices can connect, with compliance policies.
Monitoring & Threat IntelligenceReal-time analytics, integration with Threat Intelligence feeds and automated responses.

Companies with complex networks, distributed users, branch offices, hybrid environments (cloud + on-premises) or regulatory compliance needs (such as LGPD and PCI-DSS) benefit directly from CND.

NDR · Network Detection and Response

NDR: full visibility into everything that flows through your network.

NDR is CND's network detection and response layer. Instead of looking only at the perimeter, it analyzes internal traffic behavior to reveal threats that firewalls and antivirus can't see — and feeds the automated response of the Open-XDR platform.

Lateral movementDetects intruders moving between machines after the initial compromise.
Command & control (C2)Identifies communication with malicious servers and hidden command channels.
Data exfiltrationFlags anomalous transfers before information leaves the environment.
Behavioral analysisLearns the network's normal pattern and alerts on deviations — without relying solely on signatures.
Encrypted trafficDetects threats even in encrypted connections, through metadata and behavior.
Integrated responseNetwork signals trigger Open-XDR's automated response in real time.

NDR works alongside IDS/IPS, NGFW and NAC, giving the Autonomous SOC the network context needed to detect and contain attacks in progress. Explore the Open-XDR platform →

Frequently asked questions

Frequently asked questions about CND and NDR

It is detection and response based on network traffic behavior, revealing threats that firewalls and antivirus software cannot see — such as lateral movement and communication with malicious servers.

No. It complements those controls, detecting what has already passed the perimeter and is moving inside the network.

Yes, through metadata and behavior analysis, without relying solely on signatures.

Network signals feed the Open-XDR platform, which triggers automated containment in real time.
