The second iRules Contest of the year wrapped up at AppWorld Berlin this week. This contest was looking towards the future, challenging participants to write an iRule that goes beyond BIG-IP’s built-in capabilities. The theme, using WebSockets or the Message Routing Framework, inspired iRules preventing abuse and intrusion. At the heart of it, we’ve loved the creative innovation of the iRules written for this years’ contests. The AppWorld Berlin iRules Contest submissions were inspiring. Across the board, judges’ feedback on the top contenders shared a common theme: these solutions are interesting. The winning iRules were well-documented, easy to understand, with clear potential value for production use. Without further ado, we’re proud to announce the winners of the AppWorld Berlin iRules Contest: Grand Prize Winner - Goerle_dev Rule: WS-Exfil-Shield: Catching What WAFs Miss After the 101 Handshake Summary This iRule addresses gaps in traditional WAFs by extending session-level, behavior-based threat detection to WebSocket traffic using real-time inspection within F5 BIG-IP. Detection operates in two stages; an initial timing-based heuristic is followed by payload validation using AI. Malicious actors are either blocked or routed to a honeypot for isolation and further observation. This iRule closes the gap that openly documented by major WAF vendors, post-handshake Websocket blind spot, with a practical, SIEM-ready enforcement. 2nd Place - Injeyan_Kostas Rule: WS-Shield: WebSocket Abuse Detection & Adaptive Enforcement Gateway Summary This iRule addresses securing WebSocket traffic by enabling real-time, behavior-based enforcement in F5 BIG-IP to proportionally mitigate abusive patterns without application changes. It introduces a behavioral enforcement engine designed to secure WebSocket traffic with adaptive, real-time mitigation without requiring application changes. Rather than relying on static thresholds, the system dynamically responds to behavior. Clean traffic naturally recovers, while abusive patterns escalate through enforcement tiers until they are cut off. This allows it to detect subtle, persistent attacks that traditional rate limiting often misses. In testing, the iRule identified and disconnected a bot sending repetitive payloads every half second, without triggering a rate threshold. The iRule adds an extensible, behavior-driven security layer that enables adaptable defenses with minimal investment, despite optional external dependencies. 3rd Place - Robb-Fr Rule: Generic iRule Based on Datagroup Parsing Summary This iRule addresses the complexity of migrating large numbers of Apache virtual hosts by centralizing flexible traffic routing and redirection logic within F5 BIG-IP using simple, extensible datagroups. It turns input into a simple form into a datagroup entry that CREATES iRULES for things like redirects, pools, error pages, rewrites, and more. This iRule is accessible to a wide range of F5 practitioners, as F5 expertise is not required. There are no direct iRule edits, and no way for them to break the device. This iRule lowers operational friction by enabling non-NetOps teams to manage complex traffic flows, improving agility during large-scale migrations. Category Awards The 20 Lines or Less Award - Kai_Wilke In honor of Colin Walker - short on lines, long on legend. The scroll bar never stood a chance. Rule: SUPER-WEBSOCKET-HANDSHAKE-LOGGER™® (SWHL) iRule The Layered Defense Award - ChristianEssel For elegant use of nested virtual servers to solve problems the apps won't. Rule: Layered Virtual ICAP Scanning Solution Gratitude A big thank you to all contestants who participated in the AppWorld Berlin iRules Contest.

As we plan more contests for the year, we’re looking beyond iRules, with potential to expand to all programmability. The future is coming for us all; let’s greet it and move forward together.Win Big in Vegas: The iRules Contest is back with $5k on the line at AppWorld 2026

Grand Prize Winner - Injeyan_Kostas Rule: LLM Prompt Injection Detection & Enforcement Summary This iRule addresses the emerging threat of prompt injection attacks on AI APIs by implementing a real-time detection engine within the F5 BIG-IP platform. This iRule operates entirely within the data plane, requiring no backend changes, and enforces a configurable security policy to prevent malicious content from reaching language models. By utilizing a multi-layer scoring system and managing patterns externally, it allows security teams to fine-tune detection and adjust thresholds dynamically. 2nd Place - Marcio_G & svs Rule: AI Token Limit Enforcement Summary This iRule addresses the critical challenge of resource control in on-premise AI inference services by enforcing token budgets per user and role. By leveraging BIG-IP LTM iRules, it validates JWTs to extract user and role information, applying role-based token limits before requests reach the inference service. This ensures that organizations can manage and protect their AI infrastructure from uncontrolled usage without requiring additional modules or external gateways. 3rd Place - Daniel_Wolf Rule: JSON-query'ish meta language for iRules Summary This iRule addresses the complexity and inefficiency of JSON parsing in F5's BIG-IP iRules by introducing a framework that simplifies the process. It provides a set of procedures, [call json_get] and [call json_set], which allow developers to efficiently slice information in and out of JSON data structures with a clear and concise syntax. This approach not only reduces the need for deep JSON schema knowledge but also improves performance by approximately 20% per JSON request. Category Awards The (Don’t) Socket To Me Award - mcabral10 Because not every AI agent deserves a socket to speak into. Rule: Rate limiting WebSocket messages for Agents The Rogue Bot Throttle Jockey Award - TimRiker Wrangling distributed egress so your edge doesn't have to beg. Rule: AI/Bot Traffic Throttling iRule (UA Substring + IP Range Mapping) The Don't Lose the Thread Award - Antonio__LR_Mex & rod_b Session affinity for the age of streaming intelligence. Rule: LLM Streaming Session Pinning for WebSocket AI Gateways The 20 Lines or Less Award - BeCur In honor of Colin Walker - short on lines, long on legend. The scroll bar never stood a chance. Rule: Logging/Blocking possible prompt injection The Budget Bodyguard Award - Joe Negron Security hardening for those who write TCL instead of checks. Rule: Poor Man's WAF for AI API Endpoints Gratitude Tnanks to buulam for championing the return of iRules contest, this would not have happened without his grit and tenacity. Thanks to our judges: John_Alam Joel_Moses Moe_Jartin Chris_Miller Michael_Waechter dennypayne Kevin_Stewart Austin_Geraci Thanks to Austin_Geraci and WorldTech IT throwing in an additional $5,000 to the grand prize winner! Amazing! Thanks to the contestants for giving up their evening to work on AI infrastructure challenges. Inspiring! Thanks to the F5 leadership team for making events like AppWorld possible. What's Next? Stay tuned for future contests, we are not one and done here. Could be iRules specific...or they could expand to include all programmabilty.
