Military-grade DDoS protection, HAProxy-powered, with real-time analytics. Keep your players online while we handle the attacks.
Real numbers from our global infrastructure — attacks blocked, connections secured, and servers kept online 24/7.
Real-time map of attack origins across our protected server network. Every dot is an active threat being neutralized.
Universal compatibility
If your game runs on TCP, TCP-Shield can protect it. No modifications needed.
Powerful features
Built specifically for game server operators
L3/L4/L7 protection filters volumetric, protocol, and application-layer attacks before they reach your server.
Automatically block known attackers and botnets using our continuously updated threat intelligence database.
Restrict access by country. Block entire regions known for attack traffic while allowing your player base through.
Repeat offenders escalate automatically — from connection tracking to kernel-level drops. Persistent attackers get harder blocks with zero manual intervention.
Your game server sees the real player IP, not the proxy IP. Full compatibility with ban systems and analytics.
Live traffic graphs, attack maps, connection stats, and latency monitoring from your dashboard.
Per-IP connection rate limits stop connection flood attacks and prevent resource exhaustion.
Your dedicated proxy node spins up automatically in the cloud within minutes. No tickets, no manual setup — just configure and go live.
Protect up to 30 TCP ports per server. Game server, login server, chat server — all behind one proxy. Full support for complex game architectures.
AI analyzes traffic every 5 minutes, detecting coordinated botnets and slow-drip attacks invisible to rule-based filters. Auto-blocks threats automatically.
Every admin and user account is protected with time-based one-time password (TOTP) two-factor authentication. Compatible with Google Authenticator, Authy, and any TOTP app.
Under the hood
Every connection passes through four independent security layers. An attacker must bypass all four to reach your server — and they can't.
Packet-Level Filtering
Volumetric floods are dropped at the kernel level before they consume any application resources. The fastest possible rejection.
Connection Tracking & Auto-Ban
Connection tracking, rate monitoring, and automatic banning of IPs that exceed thresholds. Smart detection of attack patterns.
IP Reputation + GeoIP
Real-time threat scoring, country-level blocking, and behavioral analysis. Known botnets are blocked before the first packet.
AI Pattern Analysis
AI monitors every server every 5 minutes. Detects coordinated botnets, slow-drip attacks, and distributed floods that rule-based systems miss. Auto-blocks threats in seconds.
Full visibility
A purpose-built dashboard that shows connection stats, attack patterns, blocked IPs, and system health — updated live.
Simple setup
No technical knowledge required. No server modifications. No downtime.
Create an account, enter your game server IP and ports. Set connection limits, rate thresholds, and choose geo-blocking rules.
A dedicated proxy node is spun up instantly in your chosen region. Our system automatically configures firewall rules, traffic proxying, and monitoring — fully hands-off.
Give players the new proxy IP address. No client patches needed, no plugins, no downtime. They connect normally — the proxy is invisible to them.
All traffic is filtered in real-time. Attacks are absorbed, bad IPs are auto-banned, and your players stay connected. Monitor everything from the live dashboard.
Social proof
Game server operators who protect their communities with TCP-Shield.
“We survived a 47Gbps attack during WoE that would have taken us offline for hours. TCP-Shield absorbed it completely — players reported zero lag. Worth every penny.”
“Zero downtime in 6 months since switching to TCP-Shield. Before, we were getting taken offline every major siege. Now our community actually trusts that the server will be up.”
“Setup took 4 minutes. We pointed players at the new proxy IP and never looked back. Our server has been hit with attacks almost daily but nobody disconnects anymore.”
“Bot attacks used to crash our lobby server every week. After installing TCP-Shield, the bots just stopped having any effect. The rate limiting feature alone saved us.”
“Our realm was being targeted by rival server admins. TCP-Shield's GeoIP blocking and AI threat detection identified the attack pattern and shut it down automatically within 3 minutes.”

TCP-Shield uses a four-layer defense: kernel-level firewall rules stop volumetric floods (SYN, ACK, TCP connection floods), our smart proxy engine tracks and auto-bans abusive IPs, threat intelligence scoring blocks known bad actors before the first packet, and AI pattern analysis detects coordinated botnets that rule-based filters miss. All four layers work together before any malicious traffic reaches your game server.
Our proxies are located in major datacenters close to your game server. Typical latency added is under 2ms for same-region deployments.
No. TCP-Shield is a transparent TCP proxy. Your players connect to our proxy IP instead of your server IP directly. No client patches, no server plugins, no code changes needed. If your game uses TCP, it works with TCP-Shield.
Yes. We support GRE tunneling and TPROXY mode to pass real player IPs through to your server without any modifications.
Every connecting IP receives a real-time score from 0 to 100 based on threat intelligence feeds, connection behavior, and historical patterns. IPs scoring below 30 are automatically blocked. Suspicious IPs (30–60) are rate-limited and monitored. Clean IPs connect normally without any interference.
When an IP repeatedly triggers rate limits or abuse thresholds, it gets escalated through increasingly strict blocks. First, the proxy layer tracks and limits the connection. If the IP persists, it escalates to a kernel-level firewall drop — the most efficient form of blocking. This happens automatically with zero manual intervention.
Yes. Our GeoIP blocking feature uses commercial-grade geolocation data to let you block up to 50 countries with a single toggle. This is especially useful for game servers that serve a specific region and want to eliminate attack traffic from countries with no legitimate players.
Under 5 minutes. Add your server IP, configure your ports, and point your DNS to the proxy. Our agent handles the rest automatically.
We support any TCP or UDP game server — MU Online, Lineage 2, Ragnarok Online, World of Warcraft private servers, Minecraft, FiveM, and many more.
AI Security Guard uses advanced AI to analyze traffic patterns across your proxy servers every 5 minutes. It detects coordinated botnet attacks, slow-drip floods, and distributed attacks that rule-based filters miss — because those attacks stay below per-IP thresholds individually but are obvious when viewed as a group. When a threat is detected, it can automatically block the offending IPs for up to 1 hour. You can enable or disable AI monitoring and auto-blocking independently from your dashboard.
Yes. All plans are month-to-month with no contracts. Cancel from your dashboard at any time and your subscription ends at the current billing period. We also offer a free trial plan so you can test everything before paying.
