Advanced SecOps AI threat detection capabilities
Stop sophisticated manipulation tactics before they reach your models. Nex Firewall utilizes advanced heuristic and semantic scanning to uncover hidden exploits, jailbreak attempts and system prompt extraction attacks.
Our engine evaluates the underlying intent of every application request. If a user tries to trick your chatbot into revealing restricted database structures or violating corporate rules, Nex Firewall intercepts and neutralizes the threat instantly.
1
Automated protection against OWASP Top 10 for LLM vulnerabilities
Align your application security with the highest industry standards. Nex Firewall is engineered to deliver automated OWASP Top 10 for LLM mitigation, systematically addressing critical application-layer risks.
From blocking data poisoning attempts to preventing insecure plugin consumption and sensitive information disclosure, our gateway shields your development investments against the most destructive security flaws in modern AI engineering.
2
Real-time AI threat monitoring and SIEM/XDR integration
Your security analysts cannot defend what they cannot see. Nex Firewall delivers complete SecOps AI threat detection by transforming abstract LLM interactions into actionable security telemetry.
The platform generates detailed, standardized log data for every anomalous request. These insights stream directly into your existing SIEM (Splunk, Microsoft Sentinel) or XDR platforms, giving your SOC analysts complete, unified visibility over your entire AI ecosystem.
3
Instant Incident response frameworks tailored for AI attacks
When an application comes under a coordinated attack, every second matters. Nex Firewall enables your team to deploy automated AI incident response EU playbooks directly at the proxy layer.
Security operations can configure the gateway to automatically throttle suspicious API tokens, temporarily block offending IP addresses or flag high-risk accounts for manual review. This proactive stance ensures your enterprise containment strategies execute at machine speed.
4
Hidden vulnerabilities in custom AI implementations and public APIs
Building corporate software on top of public or private large language models creates unique security risks at the application layer. Standard web security tools cannot decipher the semantic meaning of AI requests, leaving your business exposed to critical threats:
-
The Injection risk - Attackers can craft hidden instructions within user inputs to hijack your AI, forcing it to bypass safety filters, leak system prompts or execute unauthorized commands.
-
The Insecure output threat - If an LLM generates a malicious payload or code snippet, a vulnerable application might execute it directly, leading to remote code execution or internal data breaches.
Secure your infrastructure using a dedicated LLM API firewall
Nex Firewall provides an intelligent, automated layer of defense engineered specifically for modern application stacks. Operating as an inline proxy, it delivers comprehensive prompt injection defense by dynamically sanitizing both incoming user prompts and outgoing model responses.
-
Seamless API compatibility - Works out of the box with major AI providers and custom models, requiring absolutely zero modifications to your application’s core code.
-
Enterprise-grade scalability - Built to handle high-volume enterprise API traffic with a near-zero latency footprint, keeping your user experience flawless and fully secure.
