FiveM server hosting

Learning how to install FiveM anti-cheat is essential for server owners who want to maintain a fair, secure, and enjoyable gaming environment in 2025. As FiveM servers continue to grow in popularity, protecting your community from cheaters, exploiters, and malicious scripts has become a top priority. This comprehensive guide walks you through every step of implementing robust anti-cheat solutions on your FiveM server, from selecting the right tools to configuring them properly for maximum protection.

Understanding FiveM Anti-Cheat Systems in 2025

Before you install FiveM anti-cheat solutions, it’s crucial to understand how these systems work and why they’re indispensable for modern servers. Anti-cheat software monitors player behavior, detects unauthorized modifications, and prevents exploit execution in real-time. FiveM servers face unique security challenges because they run on a modified GTA V client, making them vulnerable to resource injections, aim assists, ESP hacks, and menu injectors.

The most effective anti-cheat systems operate on multiple layers. Client-side detection monitors player files and memory for suspicious modifications, while server-side protection validates actions, checks weapon damage calculations, and monitors spawn patterns. Modern anti-cheat solutions designed for FiveM integrate seamlessly with your server resources and work alongside your framework, whether you’re running ESX, QBCore, or vRP.

When selecting an anti-cheat solution, consider factors such as detection accuracy, performance impact, update frequency, and community support. Popular options in 2025 include FiveGuard, Badger’s Anti-Cheat, and custom-scripted solutions. Many server owners combine multiple detection methods for comprehensive coverage, implementing screenshot functionality, explosion detection, teleport prevention, and weapon damage validation simultaneously.

The hardware infrastructure supporting your FiveM server significantly impacts anti-cheat performance. At Nexus Games, our FiveM hosting plans utilize the AMD Ryzen 9 7950X3D processor with 16 cores and 32 threads operating at frequencies up to 5 GHz, paired with DDR5 ECC RAM and NVMe SSD storage. This configuration ensures that anti-cheat systems run smoothly without introducing lag or performance degradation, even during high-player-count scenarios.

Step-by-Step Guide to Install FiveM Anti-Cheat

Preparing Your Server Environment

Before installing any anti-cheat resource, ensure your FiveM server is properly configured and up-to-date. Log into your server control panel—if you’re using Nexus Games hosting, you’ll access our intuitive Nexus Panel—and verify that your server artifacts are current. Outdated server builds may contain security vulnerabilities that compromise anti-cheat effectiveness.

Create a complete backup of your server files, including your resources folder, server.cfg, and database. This precaution allows you to restore functionality quickly if configuration conflicts arise during anti-cheat installation. Navigate to your resources directory and create a new folder named [anticheat] to keep your security resources organized and easily identifiable.

Review your existing resources for potential conflicts. Some older scripts may interfere with anti-cheat detection systems, particularly those that modify player coordinates, weapon systems, or vehicle spawning. Document any custom modifications you’ve made to core resources, as these may require adjustment after anti-cheat implementation.

Installing and Configuring FiveGuard Anti-Cheat

FiveGuard represents one of the most comprehensive anti-cheat solutions available for FiveM in 2025. To install FiveM anti-cheat using FiveGuard, first visit the official FiveGuard website and create an account. Purchase a license appropriate for your server size—subscriptions typically range based on player slots and feature sets.

Download the FiveGuard resource package and extract it to your server’s resources directory. The package includes multiple components: the core detection module, web panel integration files, and configuration templates. Place the FiveGuard folder inside your [anticheat] directory.

Open the config.lua file within the FiveGuard resource using a text editor. This configuration file controls detection sensitivity, punishment methods, and monitoring features. Key settings to configure include:

  • Detection Modules: Enable weapon damage validation, explosion detection, teleport prevention, godmode detection, and spectate mode monitoring
  • Punishment Settings: Define actions for detected cheaters—options include automatic kicks, temporary bans, permanent bans, or admin notifications
  • Whitelist Configuration: Add admin identifiers to prevent false-positive detections during server management
  • Screenshot Functionality: Enable automatic screenshot capture when suspicious activity is detected
  • Discord Integration: Configure webhook URLs to receive real-time detection alerts in your Discord server

Edit your server.cfg file to ensure FiveGuard starts correctly. Add the following line in the resources section:

ensure FiveGuard

Important: Place this line after your framework (ESX, QBCore, etc.) but before gameplay resources that might be exploited. This load order ensures the anti-cheat initializes early enough to monitor all subsequent resource activity.

Implementing Server-Side Detection Scripts

Complement your primary anti-cheat with custom server-side detection scripts. These lightweight resources target specific exploit methods common in your server’s game mode. For roleplay servers, implement vehicle spawn monitoring, ped creation limits, and entity cleanup scripts. For racing servers, focus on speed validation and checkpoint verification.

A basic server-side weapon damage validator prevents unrealistic damage values. Create a new resource called damage-validator in your [anticheat] folder with the following server-side script:

AddEventHandler('weaponDamageEvent', function(sender, data)
    local maxDamage = 100
    if data.weaponDamage > maxDamage then
        CancelEvent()
        DropPlayer(sender, 'Suspected damage modification detected')
        print('^1[ANTICHEAT] Player ' .. GetPlayerName(sender) .. ' kicked for damage modification')
    end
end)

This script intercepts weapon damage events, validates damage values against realistic thresholds, and automatically kicks players exceeding limits. Adjust the maxDamage variable based on weapons available in your server configuration.

For explosion detection, implement a similar approach that logs explosion coordinates and flags unusual patterns:

AddEventHandler('explosionEvent', function(sender, ev)
    local playerCoords = GetEntityCoords(GetPlayerPed(sender))
    local distance = #(vector3(ev.posX, ev.posY, ev.posZ) - playerCoords)
    
    if distance > 500.0 then
        CancelEvent()
        TriggerEvent('anticheat:logSuspiciousActivity', sender, 'Remote explosion detected')
    end
end)

Configuring Client-Side Protection

While server-side detection forms the backbone of anti-cheat systems, client-side monitoring adds an additional security layer. Most comprehensive anti-cheat solutions include client-side components that scan for known cheat signatures, monitor memory modifications, and detect injected DLLs.

When you install FiveM anti-cheat with client-side components, ensure all players download required files during connection. Modern anti-cheat systems handle this automatically through FiveM’s resource streaming system. Configure client-side detection sensitivity carefully—overly aggressive settings generate false positives, while lenient configurations miss sophisticated cheats.

Client-side screenshot functionality provides valuable evidence during ban appeals. Configure screenshot resolution and frequency in your anti-cheat settings. Most systems allow automatic screenshots triggered by detection events or manual requests from administrators. Store screenshots securely and implement retention policies compliant with privacy regulations in your jurisdiction.

Optimizing Anti-Cheat Performance and Maintenance

Performance Considerations

Anti-cheat systems consume server resources—CPU cycles for validation calculations, RAM for pattern matching databases, and bandwidth for screenshot transmission. Properly optimized configurations minimize performance impact while maintaining detection effectiveness. The robust hardware infrastructure at Nexus Games, featuring 1 Gbps network bandwidth and high-frequency AMD Ryzen processors, ensures anti-cheat systems operate smoothly without degrading player experience.

Monitor server performance metrics after anti-cheat installation using built-in FiveM commands like resmon. Track resource consumption for your anti-cheat resources and identify performance bottlenecks. If anti-cheat systems consume excessive CPU, reduce screenshot frequency, disable less critical detection modules, or optimize custom validation scripts.

Database optimization becomes critical as your anti-cheat logs grow. Implement automatic log rotation, archiving old detection events while maintaining quick access to recent data. Structure your database queries efficiently—index frequently searched columns like player identifiers and detection timestamps. For large communities, consider migrating anti-cheat logs to dedicated database instances to prevent performance degradation of core gameplay databases.

Regular Updates and Threat Intelligence

Cheat developers constantly evolve their methods to bypass detection systems. Maintaining effective protection requires regular updates to your anti-cheat solutions. Subscribe to update notifications from your anti-cheat provider and implement new versions promptly. Most commercial solutions provide automatic update mechanisms that download and apply patches without manual intervention.

Join FiveM security communities and anti-cheat discussion forums to stay informed about emerging threats. Popular platforms include the official FiveM forums, dedicated Discord servers, and Reddit communities. Share detection patterns with other server owners and learn from their experiences implementing anti-cheat strategies.

Conduct regular security audits of your server configuration. Review admin access lists, verify whitelist entries remain current, and test detection systems with controlled exploit attempts in isolated environments. Document your anti-cheat procedures in server administration guides to ensure consistent enforcement and rapid response to detection events.

Handling Detection Events and Ban Appeals

Establish clear procedures for processing anti-cheat detections. Configure your system to distinguish between automatic actions (immediate kicks for blatant cheats) and admin-reviewed cases (potential false positives requiring investigation). Implement a tiered response system: first offense receives temporary bans with warnings, repeat offenders face permanent exclusion.

Create a structured ban appeal process that balances fairness with security. Require appeals to include player identifiers, detection timestamps, and explanations. Review screenshot evidence and server logs before making final decisions. Most false positives result from legitimate admin activities, resource conflicts, or network anomalies—investigation usually reveals the root cause.

Document all detection events in a centralized logging system. Record player information, detection type, evidence collected, and resolution. This database serves multiple purposes: identifying repeat offenders using alternate accounts, analyzing cheat trends over time, and demonstrating fair enforcement during appeals.

Advanced Anti-Cheat Strategies for 2025

Multi-Layered Detection Architecture

The most secure FiveM servers implement multiple complementary anti-cheat systems rather than relying on a single solution. This layered approach provides redundancy—if cheaters bypass one detection method, others catch suspicious activity. Combine commercial anti-cheat products with custom server-side validators and community-developed open-source tools.

Implement behavior analysis systems that identify cheating patterns over time rather than detecting individual exploit executions. Track player statistics like impossible kill/death ratios, unrealistic mission completion times, or suspicious wealth accumulation. Machine learning algorithms can identify anomalous behavior that rule-based systems miss, though implementation requires technical expertise and substantial player data.

Consider hardware-based identification systems that fingerprint player devices beyond simple license identifiers. These advanced systems detect hardware ID spoofing attempts and ban evasion through alternate accounts. However, implement these features carefully, respecting player privacy and complying with data protection regulations.

Community Involvement and Reporting Systems

Your player community represents your most valuable anti-cheat resource. Implement in-game reporting systems that allow players to flag suspicious behavior for admin review. Configure reporting commands accessible through chat or custom menus, collecting reporter identity, suspected cheater information, and report reasons.

Process player reports systematically using ticket management systems or dedicated Discord channels. Acknowledge reports promptly, investigate claims thoroughly, and provide feedback about actions taken. Transparent enforcement builds community trust and encourages continued vigilance against cheaters.

Reward active community members who consistently provide accurate cheat reports. Recognition programs, in-game perks, or trusted reporter status motivate continued participation in security efforts. However, guard against false reporting abuse through verification processes and consequences for malicious reports.

Legal and Ethical Considerations

Collecting player data for anti-cheat purposes involves legal responsibilities, particularly regarding privacy regulations like GDPR and CCPA. Develop clear privacy policies explaining what data your anti-cheat systems collect, how information is stored, and who accesses it. Obtain player consent through server rules accepted during initial connection.

Implement data retention policies that balance security needs with privacy rights. Delete old screenshots, logs, and player information after reasonable retention periods. Provide mechanisms for players to request their data or deletion in compliance with right-to-access regulations.

Consider the ethical implications of surveillance systems. While protecting server integrity justifies monitoring, excessive or invasive practices damage player trust. Strike appropriate balances between security and privacy, implementing only necessary detection methods and transparently communicating anti-cheat policies to your community.
