v1.0 is now live for Linux

Cyber-Immunity for
Modern Infrastructure.

Stop zero-day attacks with autonomous eBPF protection. FOTRESS is not just a firewall; it's a self-healing digital immune system that evolves with the threat.

Intelligence built on Four Pillars

Traditional firewalls rely on static rules. FOTRESS learns the "self", identifies the "non-self", and autonomously creates custom antibodies.

1. It Learns "Normal"

Before protecting a system, FOTRESS uses eBPF to build a sophisticated baseline of expected network ports and process behaviors. Any deviation is instantly flagged.

2. Long-term Threat Correlation

A patient attacker might scan a port on Day 1 and try a login on Day 9. FOTRESS’s Threat Historian correlates isolated events over time, uncovering coordinated campaigns.

3. Sees Beyond the Network

If a zero-day drops a backdoor file (e.g., shell.php), the integrated File Integrity Monitor (FIM) detects it instantly and blames the specific attacker's IP address.

4. "Self-Healing" Defense

When threat thresholds are crossed, FOTRESS doesn't just alert—it autonomously triggers a Genetic Algorithm to evolve custom rules, dropping attackers in milliseconds.

Frequently Asked Questions

Does FOTRESS impact my server's performance?
No. FOTRESS is built on modern Linux eBPF (Extended Berkeley Packet Filter) technology. Unlike traditional user-space firewalls that copy packets, FOTRESS inspects traffic directly within the kernel safely and efficiently, resulting in near-zero CPU and memory overhead.
What happens if it blocks legitimate traffic?
FOTRESS includes a learning phase where it builds a baseline of your environment. If a false positive occurs, you can easily add the IP address to the Whitelist via the web dashboard or CLI, and the change takes effect instantly without restarting the service.
Do I need to recompile my Linux kernel?
No. FOTRESS is distributed as a standard `.deb` package via our official APT repository. As long as you are running a modern Linux kernel (version 5.4 or higher, common in Ubuntu 20.04+ and Debian 11+), the eBPF hooks will attach automatically upon installation.
