Most SIEMs have zero visibility into 16,024+ AI tool domains employees use daily. Our domain intelligence feed plugs directly into Splunk, QRadar, Microsoft Sentinel, and Elastic SIEM for immediate shadow AI detection.
Your SIEM excels at detecting malware C2 traffic, credential stuffing, and lateral movement. But it completely ignores the AI tools employees use to submit proprietary data, source code, and customer records every day.
The root cause is a classification problem. Your SIEM can only alert on what it can identify.
| What Your SIEM Sees Today | What Your SIEM Misses |
|---|---|
| Malware C2 callbacks to known-malicious IPs | Employee pasting source code into AI chatbots |
| Data exfiltration to threat-intel flagged domains | POST requests uploading customer data to AI analytics tools |
| Credential stuffing and brute-force attempts | Developers using unauthorized AI code assistants |
| URLs categorized as "Malicious" or "Phishing" | AI tools hidden under generic labels like "Technology" or "Business" |
Standard URL categorization databases group AI tools under generic labels like "Technology." They cannot distinguish ChatGPT from GitHub, or an AI code assistant from a text editor.
The AI Tools Blocklist provides 16,024+ domains, each tagged with one of 18 functional categories, updated daily. Load it into your SIEM as a lookup table, reference set, or threat indicator.
Standard URL databases label AI tools as "Technology" or "Information Technology." The AI Tools Blocklist provides 18-category granularity that turns noise into signal.
POST requests to AI tools carry the highest risk. Without domain classification, your SIEM cannot differentiate data submissions to AI tools from ordinary API calls, making shadow AI detection impossible.
Splunk's CSV lookup mechanism is the fastest integration path. Import the domain feed, and every search across proxy, DNS, and firewall logs gets real-time AI classification enrichment.

domain field so that any SPL search can use the lookup command for enrichment.
| lookup ai_tools_blocklist domain AS dest_domain in any search to add AI context.
Lists every AI tool accessed, access frequency, unique users, and total data sent. Your baseline visibility report.
Fires every 15 minutes when an employee POSTs >5 KB to a high-risk AI tool. Severity tiers by payload size and risk score.
Detects AI tools not in your baseline. The earliest indicator of unauthorized AI tool adoption.
Summarizes usage by AI tool category for weekly reporting. Shows event counts, unique users, and data submission volume.
Load the AI Tools Blocklist as a threat intelligence feed using the threatintel framework. AI tool access events automatically contribute to per-user and per-asset risk scores.
Configure the feed as a domain indicator type in ES's threat intelligence management. The correlation search Threat Activity Detected automatically flags users whose AI activity exceeds your risk threshold.
QRadar's in-memory reference sets are ideal for high-volume domain matching. They enable real-time evaluation of every event against the AI Tools Blocklist with minimal performance impact.

Map AI tool offenses to a dedicated playbook that automatically enriches with tool category, queries Active Directory for user department and manager, and creates a ticket for high-risk categories.
Auto-escalate for "Code Generation," "Data Analytics," and "AI Agents" categories. Reduces mean time from detection to investigation from hours to seconds.
Sentinel's native integration with Defender for Endpoint, Entra ID, and Purview makes it ideal for AI tool detection in Microsoft-centric environments. The AI Tools Blocklist imports as a watchlist with sub-second KQL query performance.

Enrich events at index time using an Elasticsearch enrich policy. Every proxy, DNS, and firewall event is tagged with AI metadata before indexing.
Per-user and per-department baselines surface behavioral shifts: new tool adoption, data upload spikes, and off-hours access patterns.
Critical for data exfiltration, high for data submissions, medium for new tool adoption, low for access monitoring. Zero critical events missed.
AI tool detection quality depends on your log sources. Most default logging configurations exclude the fields needed for effective detection.
Three critical data elements must be captured: the full destination domain or URL, the HTTP method (GET vs POST), and the request payload size.
Web proxy logs are the richest data source — full URL, HTTP methods, payload sizes, and user identity. Ensure these fields are logged:
%>a (client IP), %un (username), %rm (HTTP method), %ru (URL), %>st (bytes sent)hostname, url, requestmethod, requestsize, loginmisc field (full URL) and bytes_sent. Requires SSL decryption.DNS logs capture every AI tool access attempt, since every connection starts with a DNS resolution. Limited to domain visibility only — no payload data.
EDR platforms capture AI tool access even when network controls are bypassed — personal hotspots, VPN split tunneling, etc.
DeviceNetworkEvents table captures outbound connections with process-level contextThe combination of proxy, DNS, and endpoint logs creates a three-layer detection mesh. AI tool usage becomes extremely difficult to evade regardless of network path.
Proxy logs (Squid, BlueCoat, Zscaler), firewall URL filtering logs (Palo Alto, Fortinet, Check Point), and DNS query logs. Best with centralized egress and SSL decryption.
EDR network telemetry (Defender for Endpoint, CrowdStrike Falcon, SentinelOne), browser extension telemetry, and OS-level DNS client logs. Captures access even when network controls are bypassed.
Single-event detection generates noise that overwhelms any SOC. Effective monitoring requires multi-event correlation that combines domain intelligence, network telemetry, and identity context into high-confidence alerts.
The goal: surface data submissions to high-risk tools, sudden adoption changes, and policy-violating usage by privileged accounts — while suppressing low-risk browsing activity.
Triggers when Finance, Legal, HR, or Executive users access AI tools with risk score >75. Medium severity by default, escalates to High on POST >10 KB.
Triggers when a single user submits >100 KB to AI tools within one hour. Detects systematic document or dataset uploads requiring DLP investigation.
Triggers when a user accesses an AI tool category they've never used before. A developer using AI healthcare tools may indicate credential compromise or policy violation.
Triggers on AI access outside normal working hours. Combined with high-risk categories or large data submissions, this is a strong insider threat indicator.
When an AI tool alert fires, analysts should follow a structured workflow for consistent investigation quality and compliance documentation.
Identify the user, department, role, and data access level. Query AD and HR systems. Check if the tool is sanctioned or prohibited.
Evaluate risk score and category from blocklist metadata. Assess data volume submitted. Cross-reference with risk assessment scoring.
Informational → log. Medium → notify user. High → escalate to manager. Critical → immediate access revocation and incident response.
Document the playbook in your SOAR platform and link it directly from the SIEM alert. Tier 1 analysts should access it in one click for consistent triage across shifts and skill levels.
Your dashboard should serve three audiences: SOC analysts (real-time triage), security managers (weekly trends), and compliance teams (regulatory reporting evidence).
