Running Game Protection
Helps detect unauthorized changes or interference while the protected game is running.
FalconEye Shield
Multi-layer protection for Ragnarok Online, with simple controls for server owners.
FalconEye combines client-side and server-side protection to help stop modified clients, bots, macros, suspicious tools, unauthorized game changes and untrusted connections. The technical security stays in the background while the Customer Dashboard gives you easy controls, build tools and readable security logs.
Security note: this page explains what FalconEye protects, not how its internal detection works. Exact checks, signatures, thresholds, packet rules and validation methods are intentionally not published.
Core Security
Protection that works automatically in the background.
These protections are designed so a server owner does not need to understand reverse engineering or anti-cheat internals.
2012-2026 Ragnarok EXE Compatibility
FalconEye supports Ragnarok Online client generations from 2012 through 2026, with the protected build matched to the customer's actual game EXE and server profile.
Secure Launch Validation
Helps verify that the protected client starts through an authorized launch path before the game session is treated as trusted.
Protected Client / Server Communication
FalconEye protects its client-to-server security communication against invalid, replayed or out-of-session traffic without exposing the underlying protocol details.
Client Tamper Protection
Checks important FalconEye and game components so unexpected modifications can be rejected.
Unauthorized Injection Protection
Helps stop outside programs from inserting unauthorized code into the protected game session.
Suspicious Tool Protection
Helps identify programs commonly used to inspect, alter or interfere with a protected game client.
Protected File Integrity
Detects unexpected changes to important protected files used by the game and FalconEye.
GRF Integrity Protection
Lets the server owner protect the active FalconEye GRF and update its trusted identity when needed.
Custom File Protection
Add your own DLL, GRF or other client files to FalconEye's protected-file list.
Verified FalconEye Build
Helps ensure the client is using FalconEye files prepared for the correct server and license.
License & Profile Validation
FalconEye ties protected builds and server settings to the assigned server profile instead of treating every build as interchangeable.
Protected Login Verification
Helps ensure a player reaches the protected server using an authorized FalconEye client session.
Protected Session Continuity
Continues checking that the active game session remains the same trusted session from login into gameplay.
Connection & Packet Protection
Helps reject invalid, repeated or suspicious protected-game communication that does not match a normal session.
Invalid / Replayed Session Protection
Helps stop stale or reused protected-session data from being accepted as a fresh legitimate connection.
No-Delay & Speed Abuse Protection
Helps detect gameplay actions occurring faster or differently than the protected server expects.
Bot / OpenKore Protection
Helps prevent unauthorized bot programs from behaving like a normal FalconEye-protected player.
Macro & Auto-Clicker Protection
Helps identify suspicious automated input and repeated macro-style behavior.
Gaming Peripheral Awareness
Macro-capable gaming hardware can be considered as context without treating the hardware itself as automatic proof of cheating.
Hardware Identity
Lets FalconEye recognize the same PC across protected sessions for server-owner hardware rules.
Hardware Ban Support
Server owners can track and enforce hardware-based restrictions without relying only on account names.
Max Clients per PC
Choose how many FalconEye-protected game clients one PC may run at the same time.
PC Environment Checks
Helps identify suspicious or unusual runtime environments while avoiding a simple one-signal-is-cheating approach.
Block Applications
Add selected applications that should not be allowed to run together with the protected game session.
Server-Side Gameplay Monitoring
FalconEye also observes protected gameplay on the server side so protection is not based only on the Windows client.
DLL Revision Enforcement
Control whether players may use the current FalconEye revision only or receive a temporary previous-revision update window.
Untrusted Session Rejection
If an important security requirement cannot be verified, FalconEye is designed not to silently treat that session as trusted.
Multiple Protection Layers
FalconEye combines different client, server, session, file and behavior protections instead of depending on one simple check.
Customer Controls
Customize the experience without exposing the security internals.
These are practical options the server owner can manage from FalconEye without rebuilding the whole anti-cheat design.
Security Policy
Choose a customer-friendly protection profile such as Balanced, Compatibility or Strict for supported behavior settings.
Anti-Macro Controls
Enable or adjust supported anti-macro options from the Customer Dashboard.
Anti-Zoom Hack / Zoom Control
Choose the allowed zoom profile for your server and help keep players within the camera policy you configured.
LGP / RCX Overlay
Enable supported visual helpers separately from the core anti-cheat and use the available LGP presentation options.
Name & Personal Guild Color Profiles
Enable profile-based character colors. A player's selected Name Color also follows the party label and remote public chat, while Guild Color is personal to that character instead of changing the whole guild.
Custom Splash Screen
Replace the FalconEye startup image with your own server branding through the dashboard build tool.
Custom Game Window Name
Set your server name for the protected game window, or leave it blank to keep the original EXE title.
Server IP & Port Profiles
Manage the server endpoints assigned to the license, including the public Server IP and Login, Char and Map ports used by the protected rAthena server.
Protect Your Own Client Files
Add your own important client files to the protected list and remove them later when no longer needed.
GRF Update Tool
Update the trusted FalconEye GRF identity after you finish changing your protected GRF.
Custom Blocked Applications
Add or remove applications you do not want running while players use your protected client.
Client Limit per Hardware
Set single-client, dual-client, multi-client or unlimited policy depending on your server rules.
Payment History & Manual Renewal
Review verified PayPal order history and, for renewable licenses, start a supported one-time manual renewal from the Customer Dashboard.
Light / Dark Dashboard
Use the Customer Dashboard in Light or Dark Mode with the preference saved in the browser.
FPS / VSync Support
FalconEye includes supported client-side FPS and VSync controls for compatible setups.
Live Runtime Settings
Supported settings such as LGP / RCX, Name Color and other live controls can be updated from the Dashboard without requiring a normal full client rebuild after a compatible FalconEye client is deployed.
Per-Session Enforcement
Security actions target the affected protected session so another legitimate FalconEye client on the same PC is not treated as the same session.
Build & Integration
Tools for deploying FalconEye without making customers learn the internals.
The Customer Dashboard separates common client, source, DLL, GRF and manual integration workflows into simple tools.
ClientSide Builder
Upload the game-client package containing the active game EXE and receive the matching FalconEye-protected client package.
rAthena SourceSide Builder
Upload your rAthena src folder and receive the FalconEye source integration prepared for that profile.
FalconEye DLL Update
Update the FalconEye client component without rebuilding the full game-client package when the game EXE itself has not changed.
Build Status & Downloads
Follow the latest build result for the selected license and download successful ClientSide, SourceSide or update outputs from the Customer Dashboard.
Clean Manual Diff
Generate a clean rAthena-based manual integration package for customers who prefer to review and apply source changes themselves.
Installation Guide
Use the customer-facing installation guide for the normal first install, update, SourceSide, Enforcement, FE Logs and troubleshooting workflow.
rAthena HWID Script Support
Custom NPC scripts can use FalconEye's short public hardware ID for server-specific reward or access rules.
Profile-Bound Builds
Client and SourceSide outputs stay associated with the correct FalconEye server profile to reduce accidental cross-server mixing.
Embedded Splash Builder
Upload a PNG or BMP startup image from Build Tools and receive the matching FalconEye client update with the splash embedded in the protected client component.
