Protect data before it leaves the device
Opsiton is endpoint data loss prevention for the browser, the IDE, the terminal and desktop apps. A local agent makes the decision and a local proxy enforces it, so sensitive data is caught before it reaches AI tools, uploads or the network.
Complete endpoint coverage for modern organizations
Opsiton combines threat intelligence, AI monitoring and data loss prevention in a native endpoint agent and browser extension, managed from a single security console.
Real-time decisions at the endpoint
The local agent evaluates every URL, upload and AI prompt against your policies and returns an allow, warn or block decision before the data leaves the device.
Threat URL Detection
Real-time URL scanning with threat intelligence feeds and custom blocklists.
AI Platform Monitoring
Track and control usage of ChatGPT, Claude, Gemini, and other AI tools.
DLP Policy Enforcement
Block sensitive data from leaving your organization through the browser.
Incident Management
Automatic incident creation with email alerts and severity-based escalation.
Built for security teams, loved by IT admins
Every feature is designed with security operations in mind, from policy creation to incident response. Everything works together seamlessly.
Security Analytics
Real-time dashboards with event trends, severity breakdowns, and top websites.
Device Management
Track all extension endpoints with Chrome version, IP, and heartbeat monitoring.
API-First Architecture
RESTful API with API key authentication for seamless extension deployment.
Multi-Tenant Platform
Isolated organizations with role-based access and subscription management.
Real-World Endpoint Threat & Data Leak Scenarios Stopped in Real Time
Empirically verified across macOS and Windows endpoints: from TLD phishing and Punycode lookalike domains to Shadow AI code leaks and CLI exfiltration.
Country / TLD-Based Phishing & Malicious Domain Blocking
Block suspicious top-level domains (e.g., *.cn, *.ru, *.top, *.xyz) and newly registered phishing sites at the Browser and OS Network layers before credentials or files can be submitted.
- Wildcard TLD & country domain blocking rules (*.cn, *.ru, *.top, *.xyz) enforced across all browsers and desktop utilities
- Real-time Threat URL reputation checks combined with custom organizational domain blocklists and upload restrictions
- Technical distinction: Active agent inspection blocks or warns on matching wildcard/keyword URLs; when the agent is stopped, admin-configured PAC risk domains enforce fail-closed (REQ-PRX-001)
Typosquatting & Homograph Protection
Detect and block lookalike corporate login domains (e.g., 0psiton.com, rnicrosoft.com) and Punycode/IDN homograph attacks in real time before employees enter credentials or upload sensitive data.
- Blocks deceptive character substitutions (0 for o, rn for m, l for I) and Punycode/IDN homograph domains (xn--*)
- Prevents credential harvesting and accidental file uploads on spoofed SSO, banking, and cloud workspace portals
- Instant in-browser block screen with policy justification and automatic SOC security event generation
AI Prompt & File Upload DLP (MASK & BLOCK)
Apply inline MASK or instant BLOCK actions when source code, API keys (AWS, GitHub PAT, Stripe), TCKN/SSN/IBAN, or customer tables are pasted or uploaded to ChatGPT, Claude, DeepSeek, Gemini, or Copilot.
- Deep DOM interception catches typed prompts, clipboard pastes, and drag-and-drop file uploads (PDF, DOCX, XLSX, images) before transmission
- Inline Masking (Enterprise) replaces sensitive entities with session tokens (e.g., [TCKN_1], [API_KEY_1]) so employees can use AI safely without leaking secrets
- Detects free-tier / personal LLM accounts vs. approved corporate AI tenants across 40+ AI providers
4-Surface Process-Aware Endpoint Inspection
Eliminate non-browser blind spots by combining the Browser Extension with the Native Desktop Agent, CLI/Terminal interception, and OS Network Extension (macOS NE / Windows WFP).
- Browser Extension: Chrome, Edge, Brave, and Chromium DOM inspection, paste blocking, and interactive user warnings
- Native Desktop Apps & IDEs: Inspects ChatGPT Desktop, Claude Desktop, Cursor, VS Code, Slack, and Teams traffic
- CLI & Terminal Utilities: Catches data exfiltration via curl, python, node, git, and claude-code using OS Network Extension (NE/WFP) with process attribution
Article-Level Technical Controls for Global Regulations
Opsiton maps deterministic SIT patterns, mathematical checksums, on-device OCR/NER, and inline AI prompt masking directly to enforceable regulatory obligations.
Professional · Business · Enterprise
Integrity & Confidentiality (Art. 5(1)(f)), Data Protection by Design & Default (Art. 25), and Security of Processing (Art. 32) — preventing unauthorized disclosure and masking/blocking PII before external AI transfer.
- Detects EU IBAN, national identifiers, passport numbers, emails, and unstructured personal data (NER) locally on the endpoint
- Enforces MASK (Enterprise) or BLOCK before employee prompts or files leave the device to third-party AI processors
- Zero-data-exfiltration cloud telemetry hosted in Frankfurt, EU (eu-central-1)
Professional · Business · Enterprise
Obligations concerning data security (Madde 12) — preventing unlawful processing/access to personal data and blocking uncontrolled cross-border or third-party AI transfers.
- Algorithmic 11-digit T.C. Kimlik No (TCKN) checksum validation, TR IBAN verification, and Turkish phone/address detection
- Turkish & English on-device OCR for scanned IDs, invoices, and contracts uploaded via browser or desktop apps
- Blocks or masks personal data before transmission to external cloud LLMs (ChatGPT, Claude, DeepSeek, Gemini)
Professional · Business · Enterprise
Technical Safeguards for Access Control (§164.312(a)(1)) and Transmission Security (§164.312(e)(1)) — preventing unauthorized exfiltration of Protected Health Information (ePHI) across networks and AI tools.
- Built-in SIT patterns for ICD-10 diagnostic codes, NPI provider identifiers, Medical Record Numbers (MRN), and SSN
- Inspects clinical PDFs, DOCX files, and medical image uploads locally without storing ePHI in Opsiton cloud
- Generates immutable, sanitized audit logs for security incident triage and HIPAA audit readiness
Starter · Professional · Business · Enterprise
Enterprise AI governance, Shadow AI discovery across 40+ AI providers, prompt auditing, and data leakage prevention before confidential or regulated inputs reach external AI models.
- Discovers and governs 40+ AI providers across Browser, IDE, CLI, and Desktop apps with deep DOM adapters on 6 major GenAI platforms
- Blocks unapproved/free-tier LLM usage and enforces inline token masking (`[TCKN_1]`, `[IBAN_1]`) on enterprise AI prompts
- Maintains complete prompt/token telemetry and policy audit trails per employee device and AI destination
Professional · Business · Enterprise
Protect Stored Account Data (Req. 3) and Protect Cardholder Data with Strong Cryptography During Transmission Over Open, Public Networks (Req. 4).
- Deterministic Luhn checksum verification for Primary Account Numbers (PAN — Visa, Mastercard, Amex, Troy) and CVV/Track Data patterns
- Immediately blocks unencrypted or unauthorized transmission of cardholder data over web chats, AI prompts, emails, or file uploads
- Configurable snippet masking ensures full PAN digits are never stored in security event logs

Endpoint data loss prevention, simplified
Opsiton was built for how work actually leaves an organization today. Sensitive data moves through browsers, IDEs, terminals and desktop apps — and above all through AI tools. Traditional DLP never sees most of it.
Zero Trust Security
Every URL, file upload, and AI interaction is monitored and evaluated against your organization's security policies in real time.
Complete Visibility
See exactly what is happening across all your endpoints. From AI platform usage to sensitive data exposure, nothing goes undetected.
Instant Response
Automatic threat blocking, real-time alerts, and incident management help your security team respond in seconds, not hours.
Privacy First
All data stays within your organization. Cloud control-plane metadata is hosted in Frankfurt, EU (eu-central-1), API keys are encrypted, events are tenant-isolated, and we never access your sensitive content.
