The average employee now treats the ChatGPT prompt box like a trusted therapist or a senior developer—and that’s a massive security nightmare. At RSAC 2026, ESET finally addressed the “black box” problem of GenAI with a suite of tools designed to police the entire conversation flow, not just the file system. By scanning both incoming prompts and outgoing responses in real-time, ESET is moving from traditional antivirus into the role of a sophisticated AI chaperone.

The Why: Your Employees Are Your Biggest Vulnerability
Companies are rushing to integrate AI, but they’re doing it with a blindfold on. Data shows that developers frequently paste proprietary source code into LLMs to debug it, while HR departments use AI to summarize confidential employee reviews. Once that data leaves your perimeter, it’s effectively gone. This lack of oversight is a primary driver behind what happens with AI illiteracy, as users often do not realize the privacy implications of their interactions.
ESET’s new features solve the “Prompt Leakage” and “Shadow AI” problems. We no longer live in a world where blocking the URL openai.com is enough. We need a system that understands the intent of a prompt and the sensitivity of the response. This mirrors the broader financial AI security and cybersecurity trends where protection must move from the perimeter to the data layer itself. If an employee asks an AI to “Refactor this internal API key,” ESET intends to kill that process before the “Enter” key is even hit.
How to Secure Your AI Workflow with ESET
Deploying these tools requires a shift from static firewalls to behavioral monitoring. Here is how to implement the new ESET AI security layers once they roll out to the PROTECT dashboard.
- Map Your AI Footprint. Use the ESET Cloud App Control to identify which LLMs—authorized or otherwise—your team is currently hitting. You can’t protect what you haven’t indexed.
- Configure Prompt Inspection. Set specific Data Loss Prevention (DLP) rules within the ESET console. Define “forbidden strings” such as internal project codenames, credit card patterns, or proprietary code headers.
- Enable Real-Time Response Scanning. Toggle the “Inbound AI Analysis” feature. This doesn’t just look for malware; it looks for “hallucinated” links or malicious code injected into an AI’s response by a prompt-injection attack.
- Define User Groups. Set different permissions for your DevOps team (who may need higher latitude for code analysis) versus your marketing team (who likely only need text-based creative assistance).
- Monitor the AI Sentiment Dashboard. Review the weekly telemetry. If ESET flags a high volume of “high-risk prompts” from a specific department, it’s a sign you need team training, not just more software.
💡 Pro-Tip: Don’t just block prompts; use ESET’s “User Notification” pop-up. Instead of a hard “No,” configure the alert to say: “This prompt contains proprietary code. Use the internal, self-hosted LLM instance instead.” This reduces friction and prevents employees from seeking “shadow” workarounds. This level of oversight is becoming the standard for the national AI policy framework currently being established for enterprise accountability.
The Buyer’s Perspective: Can ESET Win the AI Arms Race?
ESET is entering a crowded room. For years, “AI Security” meant using machine learning to find old-school viruses. Now, companies like Zscaler and Palo Alto Networks’ Protect AI acquisition are racing to secure the AI traffic itself.
What makes ESET’s approach compelling is its integration into the existing PROTECT ecosystem. If you are already a “Green Shop,” adding AI prompt scanning is a checkbox, not a new infrastructure project. ESET has always been leaner and faster on system resources than CrowdStrike or Microsoft Defender. However, the success of this tool depends entirely on its “False Positive” rate. If the AI security layer slows down the creative flow or flags harmless brainstorms as data leaks, users will find a way to disable it.
Compared to competitors who focus solely on the network layer, ESET’s visibility into the endpoint (the actual laptop where the typing happens) gives it a distinct advantage in seeing encrypted traffic before it hits the browser. As the industry moves toward the agentic era security, having these guards at the endpoint level will be critical.
FAQ
Does ESET read my private AI chats?
No. The scanning happens locally on the endpoint or at the gateway level to check for data patterns. The content is generally not stored by ESET unless you’ve configured specific logging for compliance audits.
Will this slow down my ChatGPT or Claude responses?
Latency is the biggest hurdle. ESET claims its light-agent technology keeps inspection under a few milliseconds, but users on slower connections may notice a slight “hiccup” during deep-packet inspection of large prompts.
Can it stop “Prompt Injection” attacks?
Yes. By scanning the *
