nuDefend blocks known attackers on any cloud or on-premise Linux server - inbound and outbound - automatically. It now also includes free country blocking (geo-blocking): allow or block traffic by country in one click, at no extra cost. One command installs a lightweight, privacy-first agent that self-updates every 30 minutes with zero telemetry.
Overview
nuDefend is a lightweight security agent that protects any Linux server - on any cloud or on-premise - by blocking known-malicious IP addresses and domains, both inbound and outbound.
A single command installs the signed, hardened agent. Every 30 minutes it fetches a cryptographically signed threat list of 45,000+ malicious domains and 44,000+ attacker IPs and enforces it at both the network (kernel firewall) and DNS layers, so threats are stopped before they ever reach the services running on your server.
nuDefend is privacy-first: the only outbound call is fetching the signed blocklist. Your logs, traffic and metadata never leave the machine - reports stay local. The agent is self-healing and restores its rules if anything tampers with them, and it fails open if a subscription lapses so you are never locked out.
Key capabilities:
- Any cloud, any server - AWS, Azure, GCP, DigitalOcean or bare metal
- Inbound and outbound protection at the network and DNS layers
- Automatic threat-list refresh every 30 minutes
- Local-only reporting with zero telemetry
- One-line install, no console to learn

Dimensions summary
This listing offers one pricing dimension: a monthly nuDefend Server License, billed per host. Each license protects one Linux server. Pricing scales linearly with the number of servers you protect. To cover more servers, you add more licenses. There are no tiers or usage-based charges. The license includes real-time inbound and outbound blocking of malicious domains and attacker IPs, plus automatic threat-feed updates every 30 minutes. Billing follows a contract model on a monthly basis.
Top-of-mind questions for buyers
One license covers one Linux server, no matter how many domains or IPs it processes. Each server you protect needs its own license. If you run several servers, you buy one license per server. The count is based on servers, not on users or devices behind them.
You install a single agent directly on your Linux server, with no extra hardware. It acts as a smart firewall that blocks malicious domains and attacker IPs in both directions. It draws on threat feeds covering over 175,000 malicious domains and 43,000 IPs, refreshed automatically every 30 minutes.
Cost scales linearly per server. Each new server you protect adds one more monthly license charge. There are no tiers or volume brackets, so protecting ten servers costs ten times the per-host rate. Removing a server removes its license charge going forward.
