Setup your firewall in minutes

A few seconds to install it, a few minutes to configure it. NethSecurity comes with an intuitive interface that allows anyone to use it effectively from the very first moment.

Our feature-rich UTM firewall ensures comprehensive defense, including advanced threat detection, real-time monitoring and traffic management.


A comprehensive interface that provides real-time insights and control over network security. It offers a centralized hub to monitor and manage firewall activities, displaying critical information such as intrusion attempts, traffic patterns, and system health.


Enhances the performance of your network by load balancing traffic across different connections, ensuring uninterrupted connectivity and reducing the risk of downtime.

Deep-packet inspection

Handled by a modified version of nDPI, NethSecurity inspects and analyzes network traffic at a granular level. It enables the identification and classification of specific applications or protocols within the data packets, allowing for detailed monitoring and control of network activities.

Virtual Private Networks (VPNs)

Support for IPsec, OpenVPN and WireGuard. Connect remote locations like data centers, branch offices or outsourced infrastructure via an encrypted link. It allows staff to work remotely as if they would be sitting in the office and allowing them to access all resources that they need fast and securely.

Interfaces and Devices

Define distinct zones, such as LAN or WAN and enabling precise security configurations. Use user-friendly labels for simplifying rule management. Empower administrators to implement granular security policies, regulate traffic flow, and efficiently manage network resources.

Traffic Shaper

Without traffic shaping, packets are processed on a first-in/first-out basis by the firewall. Quality of Service (QoS) prioritizes network traffic, indicating the priority and guaranteeing minimum/maximum bandwidth for specified types of traffic.

Threat shield

It keeps you safe by blocking attacks from known malicious IP addresses. These addresses are compiled into blocklists, each with a clear name that tells you its purpose and who maintains it. The confidence score is a value from 1 to 10 that indicates the quality of the list.

Stateful Firewall

Keep track of the state of network connections (such as TCP streams, UDP communication) traveling across it. Group firewall rules by category, for more demanding network setups.

Live installation

Run and use the firewall software directly from a bootable media (such as a USB drive) without needing to install it on a hard drive or storage device. Set up a temporary firewall without the need for a full installation process.

Centralized Controller

Manage multiple NethSecurity installations from a unique interface. Generate a VPN configuration and transmit it to the firewall, safely stores credentials required for accessing. Collect all logs and metrics from different NethSecurity in one place.
