Network Security carrier-grade

The FiQs deployment process was designed to minimize the time from startup to full network operability. You typically receive a ready, optimized ISO image, and the system installation itself takes just 5–10 minutes. No time wasted on manually compiling packages, resolving library dependencies or tedious configuration of low-level system services – everything needed for router and firewall operation is already preconfigured and ready to go.

Right after reboot, you're greeted by an intuitive CLI wizard that guides you through basic interface addressing and software registration in a few steps. Once you have network access, all further management moves to the clear web panel. Because key network services are factory-integrated and tested, you can immediately focus on defining access rules and QoS policies instead of fighting with operating system configuration.

We believe in the quality of FiQs, which is why we offer you complete freedom to test the system in your real environment. You can take advantage of our 30-day satisfaction guarantee – install the software in your network, configure it for your specific needs and test it for a full month. If during that time you decide the system doesn't meet your expectations, we'll refund your money with no questions asked. For those who want to "click around" first, we also provide an interactive online demo of the admin panel.

Importantly, the testing phase isn't just your solo effort. From day one, we provide full technical support and remote assistance. Our engineers will help you with the installation process, resolve any issues with unusual hardware and advise on how to optimally tailor FiQs configuration to your infrastructure's specifics. We want you to purchase a solution that is already fully deployed and battle-tested, not just a "box" with a promise of working.

Hardware: Physical computer, rack server or virtual machine (VM).

RAM: Min. 4 GB (8 GB recommended for high session counts).

Disk space: Min. 100 GB (SSD recommended for fast event logging).

Architecture: The system works in both BIOS and UEFI mode.

Network interfaces: Minimum 2 independent NICs with throughput matching your link speed (1 Gbps or higher). Support for Ethernet (RJ-45) or SFP+ for fiber connections.

Yes. FiQs runs on all popular virtualization platforms: Proxmox, VMware ESXi, XCP-NG, Hyper-V, KVM and other standard-compliant hypervisors. Installation and configuration are identical to bare-metal hardware.

For maximum performance and minimal latency, the system fully supports PCI Passthrough technology. It allows physical network cards to be directly assigned to the virtual machine, bypassing the hypervisor's virtualization layer. This gives FiQs exclusive access to the hardware, eliminating CPU overhead from virtual switch handling and enabling full link throughput utilization (e.g. 10 Gbps and beyond), while maintaining stability comparable to a bare-metal installation.

Our solution is designed for anyone who wants to consciously manage their network – from experienced administrators to those just building their skills. Although FiQs is an advanced tool, you don't need to be an expert from day one.

Who do we invite to work with us?

• Ambitious juniors: If you know the absolute basics of Linux (you can log into the console and know how to edit a text file), you'll have no problem handling the system.
• Growth-oriented professionals: If concepts like routing or bandwidth management aren't foreign to you, but you prefer having expert support "at hand" – FiQs is for you.

Education and support is our mission:

For years we've been supporting the administrator community and gladly sharing knowledge. When you choose FiQs, you're not left alone with the terminal:

• Accessible documentation: Our step-by-step guide explains the installation and configuration process for virtually any scenario.
• Human-centered tech support: You can always count on our assistance – both during the initial setup and with later, more complex projects. We're happy to advise and help you understand the system's intricacies.

Don't be afraid to ask. We respond to every email and actively support less experienced colleagues. With our help, you'll quickly feel confident in the world of the Linux console, and your network will gain a professional heart.

Yes. We compile our own Linux kernel and strategic networking software packages responsible for QoS, firewall, routing and PPPoE session handling. This gives us full control over every bit of data flowing through the system.

Unlike solutions based on standard, off-the-shelf distributions, FiQs is optimized to eliminate bottlenecks in the network stack. Custom compilation of key components allows us to apply low-level patches that drastically improve traffic queuing performance and reduce firewall response times. It is this deep hardware-software integration that sets FiQs apart, guaranteeing stability even under extreme load on high-throughput links.

FiQs imposes no artificial licensing restrictions on the number of supported network elements. The system allows any configuration of physical interfaces, IP aliases and an unlimited number of tagged VLAN (802.1Q) ports. The only real limit is CPU processing power and hardware bus throughput.

The system architecture was designed with the most complex ISP topologies in mind. FiQs handles thousands of subnets, advanced multi-level addressing and dynamic virtual interface creation with ease. Whether your network relies on simple routing or a dense structure of isolated segments for business clients, the system ensures full traffic separation and routing table stability at any scale of operation.

Purchasing FiQs is an investment in your network's stability, which is why we offer a lifetime license. The system operates without any time restrictions – after the first year, your infrastructure remains fully functional, and all configured services, routing and firewall rules retain their functionality. We do not use any system "lock-out" mechanisms if a subscription is not renewed.

After the first year, you can optionally extend access to technical support and the latest updates by choosing one of three dedicated plans: Standard, Custom or Premium. If you decide not to renew the subscription, the system will continue to operate at full performance, but you will lose access to security patches and new features, and technical support will automatically switch to the Mini plan. Of course, even in such a case, we don't leave you without help – you can always count on us for contact and basic guidance if questions arise.

Yes. We understand that changing the heart of your network is a critical process, which is why we actively assist with migration from your current solution. Our engineering team conducts a detailed analysis of the existing configuration to precisely transfer what matters most: complex firewall rules, advanced QoS policies, IP addressing and client databases.

We complete most migration processes remotely within a single business day, ensuring that any service interruption is imperceptible to end users. We don't limit ourselves to simply copying settings – during configuration transfer, we audit and optimize it, tailoring it to the FiQs architecture. As a result, after migration your network often runs faster and more reliably than before. We conclude the entire process with joint testing of critical service functionality.

On a typical hardware configuration (e.g. 4-core Intel Xeon/Core i5 processor, 8 GB RAM), FiQs effortlessly handles over 2,000 active clients simultaneously. Our system operates in networks of varying scale – from small nodes with a few dozen users to extensive ISP backbones serving many thousands of subscribers on a single server.

However, keep in mind that real-world performance depends on several key factors that we always consider when advising:

Traffic type: Transferring large data packets (streaming, downloads) primarily loads network interfaces, while hundreds of thousands of small packets (online gaming, DNS queries, VoIP sessions) require more CPU processing power.

Service complexity: The number of active PPPoE sessions, depth of firewall inspection and the extent of QoS queues (traffic shaping) have a direct impact on CPU and RAM resource requirements.

Hardware layer: Performance increases drastically when using branded network cards (e.g. Intel, Broadcom) supporting hardware queuing and when leveraging PCI Passthrough technology in virtual environments.

Link throughput: Handling 1 Gbps of symmetric traffic requires a different configuration than aggregating several 10 Gbps links.

That's why we don't sell a "box in the dark" – based on your traffic statistics and network topology, we help select optimal components so you can be sure the system maintains a safe performance margin even during peak hours.

The system guarantees full, native IPv4 and IPv6 networking stack support at the kernel level. The FiQs architecture is fully prepared for modern addressing, and IPv6 configuration is available directly from the system console.

In the current version, we focus on maximum optimization of IPv4 traffic management, which still forms and will continue to form the foundation of the vast majority of networks. Although full IPv6 automation is not utilized by default in daily operations, advanced administrators can freely deploy and test the next-generation protocol on their own, leveraging the full power within the Linux system.

At FiQs, we don't believe in closed ecosystems. You receive full, unrestricted root access, giving you complete control over the operating system. You can freely install additional packages from repositories, run your own automation scripts or deploy custom monitoring and reporting services. Your device is not a "black box" – it's a flexible platform that you can fully tailor to your infrastructure's needs.

However, we know that custom requirements sometimes need expert guidance. That's why we don't leave you alone with the terminal. We provide active support for advanced integrations. Whether you need to connect FiQs with an external billing system, a Radius database, a custom API or a log collection system (e.g. ELK Stack), our engineers will help you optimize the configuration so that your custom solutions run efficiently and reliably.

The choice of FiQs version depends on your strategy for ensuring continuous network access. We offer two variants:

1xWAN version: Designed for locations with a single stable internet link. Ideal where the priority is advanced traffic management within the local network.

2xWAN version (Failover & Load-Balancing): A solution for businesses and operators where every minute of downtime means losses. This variant offers:

• Automatic Failover: The system continuously monitors the primary link's status. In case of failure, traffic is automatically switched to the backup link within just a few seconds. Once the primary link signal is detected again, FiQs automatically restores traffic to it.
• Load-Balancing: Intelligent load distribution across both links simultaneously, allowing maximum utilization of available bandwidth.
• Redundancy: Using two different providers (e.g. fiber + radio link) drastically increases the reliability of the entire infrastructure.

Important technical note: The Failover mechanism works fully transparently for clients behind NAT. When using public IP addresses assigned to a specific provider, keep in mind that after switching to the second link, this addressing may not be supported by the new provider (specific configurations are then required, e.g. BGP protocol, if providers allow it).

All other features – from the advanced Firewall and QoS to monitoring and the intuitive web panel – are identical in both versions.

Yes, of course! Our existing clients are our priority, which is why we've prepared a special loyalty program for those who have been with us for years. We believe your trust in previous versions deserves the best conditions when transitioning to the new generation of the system.
