How it works
Your existing firewalls and honeypots feed threat data into NxtFireGuard. Every suspicious IP is scored in real time, combining what your network sees with signals from the entire NxtFireGuard community. When a traffic sensor detects an IP crossing your block-threshold, it requests blocking that IP. NxtFireGuard validates and executes the block request automatically. And unlike static blocklists, every blocked IP is continuously re-evaluated and removed the moment it's no longer a threat. No manual work. No stale lists.
Just always-current protection.
Why switch
What's included
Built for teams that want serious protection without a dedicated security team to run it.
Connect your existing firewalls, honeypots, and AAA servers. NxtFireGuard ingests threat logs from all of them, no rip-and-replace required.
Traffic sensors monitor every connection in real time, scoring source and destination IPs against your local threat database before damage is done.
Every NxtFireGuard user contributes to a shared threat pool. When one organization spots a malicious IP, every other user is protected instantly.
Blocked IPs don't stay blocked forever. NxtFireGuard continuously re-scores them and removes clean IPs automatically, keeping your blocklists lean.
Set custom block thresholds per blocklist and whitelist trusted IPs across your entire setup.
Every threat event, every block, every change is logged and searchable. Know exactly what happened, when, and why.
Getting started
No weeks-long rollout. Just four steps and you're protected.
Point your existing firewalls, honeypots, or AAA servers at NxtFireGuard. If it generates logs, we can ingest it.
Supports Cisco Firepower, PaloAlto NGFW, T-Pot Honeypots, Cisco ISE, OPNsense and custom endpoints via generic API.
Install a lightweight sensor on your infrastructure. It monitors live traffic and scores every IP in real time — locally, without latency.
Feeds via syslog or port mirroring. Syncs IP scores locally so blocking decisions happen on your network, not in the cloud.
Set your blocking thresholds, attach your traffic sensors, and whitelist anything that should never be blocked.
Separate thresholds for private and public IPs. Fully configurable re-evaluation intervals.
Your firewalls poll the blocklist via HTTPS. From this point on, NxtFireGuard runs itself.
Compatible with any firewall that supports external blocklists via HTTPS — including PaloAlto, Cisco, and most enterprise appliances.
Pricing
Start free, no credit card required. Upgrade when you need more sensors, more blocklists, or dedicated support.
Every second you rely on an outdated blocklist is a second an attacker can exploit. NxtFireGuard closes that window - automatically, continuously, without your intervention.
