Introduction:
Insider data theft is no longer a rare edge case—it happens in nearly every proof-of-concept engagement, according to ORION Security CTO Jonathan Kreiner. The AI era has blown the problem wide open: employees now paste sensitive data into AI tools across every department, and open-source AI agents running on endpoints are leaking data at scale with high privileges. Traditional Data Loss Prevention (DLP) tools—built on thousands of human-authored policies—require constant tuning, generate endless false positives, and still fail to stop exfiltration. ORION Security, which recently raised $32M in Series A funding led by Norwest Venture Partners, is rewriting the rules with an AI-1ative approach that replaces rigid policies with context-aware intelligence.

You Should Know:
- The Insider Threat Is Not an Edge Case—It’s the Norm
ORION Security’s findings are sobering: in nearly every proof-of-concept deployment, the company identifies someone actively exfiltrating data from the organization. This isn’t sophisticated espionage—it’s often everyday employees moving data they shouldn’t, whether through carelessness, curiosity, or malice.
The statistics paint an alarming picture. Organizations experienced an average of 25.4 insider incidents in 2025, with negligence alone costing $10.3 million annually—a 17% year-over-year increase. Credential theft incidents rose from 4.8 in 2024 to 5.3 in 2025, with attackers increasingly targeting credentials that grant access to critical data. The total cost of insider risks now approaches $19.5 million per year.
The problem extends beyond malicious actors. Employees paste proprietary information, customer data, and confidential documents into browser-based AI tools like ChatGPT to generate responses, summaries, or code. According to LayerX research, a significant number of corporate users paste Personally Identifiable Information (PII) or Payment Card Industry (PCI) numbers directly into ChatGPT. Copy-paste has now exceeded file transfer as the top corporate data exfiltration vector, with 77% of employees pasting data into AI prompts and 32% of all copy-pastes from corporate accounts to non-corporate accounts occurring within genAI tools.
Detecting Insider Data Exfiltration on Linux:
To detect suspicious data movement on Linux systems, security teams can deploy auditd rules and monitoring commands:
Monitor all file access to sensitive directories auditctl -w /etc/ -p wa -k etc_changes auditctl -w /home/ -p wa -k home_changes auditctl -w /var/www/ -p wa -k web_changes Monitor outbound network connections (potential exfiltration) ss -tunap | grep ESTAB netstat -tunap | grep ESTAB Detect recursive grep for credentials (common insider reconnaissance) ps aux | grep "grep -r" | grep -v grep Monitor large outbound data transfers iftop -i eth0 nethogs Detect files modified in the last 24 hours that might be staged for exfiltration find / -type f -mtime -1 -size +10M 2>/dev/null
Detecting Insider Data Exfiltration on Windows (PowerShell):
Monitor file access events (requires enabled auditing)
Get-WinEvent -LogName Security | Where-Object { $_.Id -in 4663,4656 } | Select-Object TimeCreated, Message
Detect large outbound network transfers
Get-1etTCPConnection | Where-Object { $_.State -eq "Established" }
List recently modified files larger than 10MB
Get-ChildItem -Path C:\ -Recurse -File -ErrorAction SilentlyContinue | Where-Object { $<em>.LastWriteTime -gt (Get-Date).AddDays(-1) -and $</em>.Length -gt 10MB }
Check for suspicious scheduled tasks
Get-ScheduledTask | Where-Object { $_.State -1e "Disabled" }
- The AI Data Leakage Crisis: Shadow AI and Agentic Threats
The AI era has introduced unprecedented data leakage vectors. When employees share sensitive data with unapproved AI tools, it can be leaked, misused, or absorbed into public training datasets—violating trust and regulatory requirements.
The rise of agentic AI has created an entirely new attack surface. Endpoint AI agents—programs that run directly on employee devices such as laptops and developer workstations—operate outside traditional visibility and control mechanisms. These agents can read files, make API calls, and transfer data at a scale and speed no human would generate.
Shadow agents—unauthorized AI agents deployed inside an enterprise without IT and security team knowledge—represent a critical blind spot. A shadow agent that transfers personal data to an unapproved third-party provider can trigger a reportable breach without the organization ever knowing the transfer occurred.
AI Security Best Practices:
Organizations must implement AI governance frameworks that include:
- Discover and inventory all AI agents running across endpoints
- Enforce outbound HTTP allowlists for AI agents—every outbound call should require verified AI agent identity, scoped authentication tokens, and policy-based destination approval
- Sanitize training data, fine-tuning sets, and user inputs through redaction, masking, or tokenization before they touch any model
- Implement input/output sanitization for all data passed between agent orchestrators and tool endpoints
- Limit what endpoint data agents retain and implement integrity checks on stored context

]
}'
- ORION’s Approach: “EDR for Data” with Context-Aware AI Agents
ORION Security has fundamentally reimagined DLP. Instead of rigid rules and regex patterns, the platform deploys context-aware AI agents that analyze every piece of data in motion in real time and block leaks before they happen. The result: deploying DLP in a single day instead of three years.
ORION’s platform uses specialized AI agents and a proprietary LLM to continuously detect and analyze data loss indicators in real time. The system captures the full context behind every data movement, including:
- Content sensitivity — What type of data is moving?
- Data lineage — Where has this data been?
- User identity — Who is moving it?
- Behavioral intent — Why are they moving it?
- Environmental purpose — What is the workflow context?
ORION comprises six specialized agents: five collect core contextual signals, and a sixth analyzes them to detect abnormal or risky behavior. This enables automated DLP at scale with far better accuracy, drastically reduced false positives, and the ability to continuously detect and prevent new forms of data exfiltration.
Organizations using ORION have reported a massive reduction in DLP maintenance and tuning, accurate prevention of data movement beyond anticipated scenarios, and a near-zero false-positive rate. Policies still play a role, but only where they are most effective: deterministic, predictable scenarios.
Comparing Traditional vs. AI-1ative DLP:
| Feature | Traditional DLP | ORION AI-1ative DLP |
||-||
| Detection method | Static regex and policies | Context-aware AI agents |
| False positives | High (constant tuning required) | Near-zero |
| Deployment time | Months to years | Single day |
| Maintenance | Continuous manual tuning | Autonomous learning |
| Coverage | Known threats only | Known and unknown patterns |
| Data understanding | Pattern matching | Full context (lineage, intent, behavior) |
4. Step-by-Step: Implementing Context-Aware Data Protection
Step 1: Data Discovery and Classification
Before you can protect data, you need to know what you have. Implement continuous data discovery across all repositories:
Linux: Scan for sensitive data patterns using grep
grep -r -E "\b[0-9]{3}-[0-9]{2}-[0-9]{4}\b" /path/to/data SSN pattern
grep -r -E "\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+.[A-Za-z]{2,}\b" /path/to/data Email
Use clamAV for file type detection
clamscan -r --bell -i /path/to/data
Use exiftool to extract metadata from documents
exiftool -r -csv /path/to/documents > metadata.csv
Step 2: Implement Least-Privilege Access
Enforce least-privilege access across all systems. Cloud data security requires encryption for data at rest and data in transit across networks and APIs—these aren’t optional layers.
Linux: Review user permissions
find / -type f -perm -o+w 2>/dev/null World-writable files
find / -type d -perm -o+w 2>/dev/null World-writable directories
Review sudo access
cat /etc/sudoers
grep -r "NOPASSWD" /etc/sudoers.d/
Windows PowerShell: Review user permissions
Get-LocalGroupMember -Group "Administrators"
Get-LocalUser | Where-Object { $_.Enabled -eq $true }
Step 3: Deploy Endpoint Monitoring
Modern data protection requires visibility across endpoints, cloud, web, SaaS solutions, email, and other channels.
Linux: Monitor file integrity with AIDE aide --init aide --check Monitor system calls for suspicious activity strace -e trace=network,file,process -p $(pgrep -f "suspicious_process") Windows: Enable PowerShell script block logging Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\PowerShell\ScriptBlockLogging" -1ame "EnableScriptBlockLogging" -Value 1
Step 4: API Security Hardening
APIs are a major data leakage vector. Excessive data exposure through API responses is a silent problem—hundreds of endpoints each leaking a little data, compounding over time.
API Security Best Practices:
Test API endpoints for excessive data exposure Use curl to inspect API responses curl -X GET "https://api.example.com/users/123" -H "Authorization: Bearer $TOKEN" Check for sensitive data in responses (look for PII, tokens, internal IDs) curl -X GET "https://api.example.com/internal/config" -H "Authorization: Bearer $TOKEN" Implement rate limiting to prevent bulk data extraction Example nginx rate limiting limit_req_zone $binary_remote_addr zone=api_limit:10m rate=10r/s; limit_req zone=api_limit burst=20 nodelay;
OWASP API Security Recommendations:
- Expose only the necessary data and operations
- Ensure operations behave according to context
- Prevent protocol or infrastructure-based data leaks
- Use HTTPS/TLS for all secure communication
- Implement strong, modern authentication and authorization
- Sanitize error responses to avoid leaking stack traces or internal paths
Step 5: Cloud Data Security Hardening
Cloud environments require a fundamentally different approach. Perimeter thinking breaks down in the cloud—data flows through object storage, managed databases, SaaS drives, BI pipelines, and app-to-app connections.
Cloud Hardening Checklist:
1. Inventory and classify all data assets continuously
- Enforce least-privilege access with MFA and short-lived credentials
3. Implement baseline guardrails for all cloud services
4. Configure network containment with proper segmentation
5. Deploy configuration assurance to detect drift
6. Implement detection and response for data movement
5. AI Agent Security: The New Frontier
The growth in agentic use cases makes the data risk problem exponentially larger and more complex. Endpoint AI agents run directly on employee devices, operating outside traditional security controls.
Agent Security Controls:
Linux: Monitor for AI agent processes
ps aux | grep -E "(python|node|ollama|llama|GPT|claude|agent)"
lsof -i -P -1 | grep LISTEN Check for local AI service ports
Monitor outbound API calls from AI agents
tcpdump -i any -1 "host api.openai.com or host api.anthropic.com or host api.cohere.com"
Windows PowerShell: Detect AI agent installations
Get-Process | Where-Object { $<em>.ProcessName -match "python|node|ollama" }
Get-Service | Where-Object { $</em>.DisplayName -match "AI|agent|model" }
Agent Security Best Practices:
- Discover which AI agents are running across the organization
- Enforce governance policies automatically without disrupting productivity
- Implement identity-bound policies—every outbound HTTP call requires verified AI agent identity
- Use session isolation to prevent cross-session data leakage or poisoning
- Limit data retention on endpoints with integrity checks on stored context

What Undercode Say:
- Key Takeaway 1: Traditional DLP is fundamentally broken. Organizations have spent decades adding policies to legacy DLP tools, yet data loss incidents are more widespread than ever. The assumption that more policies equal stronger protection is flawed—policies only protect against known threats, leaving enterprises exposed to unpredictable, rapidly emerging patterns of data loss.
-
Key Takeaway 2: AI is both the problem and the solution. The same AI capabilities that enable employees to paste sensitive data into ChatGPT and deploy unauthorized shadow agents also provide the contextual intelligence needed to stop data leakage in real time. ORION’s approach—using specialized AI agents to understand why data is moving, not just that it’s moving—represents a paradigm shift from reactive policy enforcement to proactive, context-aware protection.
Analysis: The data leakage landscape has evolved dramatically. Insider threats are now the norm, not the exception. The AI era has created entirely new vectors—employees pasting proprietary information into public AI tools, open-source AI agents running on endpoints with high privileges, and shadow agents operating without security team knowledge. Traditional DLP, built for a pre-AI world, simply cannot keep pace.
ORION’s $32M Series A funding, less than a year after its seed round, signals that enterprises recognize the urgency. The company’s approach—replacing thousands of human-authored policies with context-aware AI agents that analyze content sensitivity, data lineage, user identity, behavioral intent, and environmental purpose—addresses the root cause of DLP failure.
The implications for security teams are profound. DLP can no longer be a compliance checkbox; it’s becoming a board-level priority. Organizations must move beyond static policies and embrace AI-1ative solutions that understand how data actually moves across modern, distributed environments.
Prediction:
-P: The DLP market, currently valued at over $3 billion and projected to exceed $10 billion by 2030, will see accelerated growth as AI-1ative solutions replace legacy policy-based tools.
-P: Enterprises that adopt context-aware AI DLP will gain significant competitive advantage by reducing security overhead from months of tuning to near-zero maintenance.
-P: Regulatory frameworks (GDPR, CCPA, HIPAA) will increasingly mandate AI-specific data protection controls, driving adoption of context-aware DLP.
-1: Organizations that continue relying on traditional policy-based DLP will experience increased data breach frequency and severity as AI-enabled exfiltration techniques outpace static defenses.
-1: The proliferation of open-source AI agents on endpoints will create a “shadow AI” crisis comparable to the Shadow IT problem of the 2010s, with many organizations unaware of data leakage until it’s too late.
-1: Insider data theft costs, already approaching $19.5M annually, will continue rising as AI tools make data exfiltration easier and harder to detect.
-P: AI-1ative DLP platforms like ORION will expand beyond insider threat detection to ransomware prevention, detecting pre-encryption data theft stages before they escalate.
-P: Security teams will shift from “policy writers” to “AI supervisors,” focusing on training and validating AI agents rather than maintaining thousands of static rules.
-1: Without proper AI governance frameworks, organizations will face increasing regulatory fines and reputational damage from AI-related data leaks.
-P: The integration of DSPM (Data Security Posture Management) with AI-1ative DLP will create unified data protection platforms that cover the entire data lifecycle.
