AI adoption is exploding across every industry. Employees are using generative AI tools for writing, coding, customer support, document summaries, data analysis, and more. These tools boost productivity—but they also introduce a massive new security problem:
Shadow AI.
Just like Shadow IT reshaped SaaS security, Shadow AI is now reshaping data loss prevention (DLP).
Employees are pasting sensitive data into AI tools without visibility, without guardrails, and without approval.
This means:
- Customer data is entering unknown LLMs
- Source code is being uploaded to unvetted models
- Internal documents are being fed into public prompts
- Confidential financials are being summarized by third-party AI
- Browser extensions with AI features can read everything on the page
And most of this happens inside the browser, where traditional DLP or CASB tools have no visibility at all.
This is why BreachFin built the BreachFin Browser Security Plugin — a lightweight, real-time browser extension that gives organizations direct visibility and control over Shadow AI and browser-based data exposure.
Shadow AI: The Invisible DLP Nightmare
AI tooling creates entirely new pathways for sensitive data to escape your perimeter:
1. Users paste internal content into ChatGPT, Gemini, Claude, Perplexity, etc.
Most organizations have no idea what is being uploaded.
No logs.
No audit trail.
No policy enforcement.
2. AI-powered Chrome Extensions can access page data
Hundreds of extensions request permissions like:
- “Read and change all your data on all websites”
- “Access clipboard”
- “Capture text on page”
Many security teams never review or restrict these.
3. Enterprise data silently flows to AI APIs
Users connect AI tools via:
- Browser extensions
- OAuth
- Workspace add-ons
These integrations create hidden APIs no one monitors.
4. No central governance over who is using what
Employees use AI tools independently, often with personal accounts.
5. Compliance frameworks have become stricter
PCI DSS, SOC2, NIST, and GDPR now require:
- Control over third-party processors
- Protection of regulated data
- Visibility into data egress channels
Shadow AI breaks every one of these requirements.
Introducing the BreachFin Browser Plugin
AI Visibility. Data Loss Prevention. Real-Time Control.
The BreachFin Browser Plugin is a direct response to the new AI-driven browser threat landscape.
It brings real-time monitoring, auditing, and control to the exact point where Shadow AI occurs:
the user’s browser.
Core Capabilities of the BreachFin Browser Plugin
1. Shadow AI Detection
The plugin identifies:
- AI websites being accessed (ChatGPT, Claude, Gemini, Copilot, Perplexity, etc.)
- AI extensions installed
- AI-powered SaaS integrations
- AI-driven workflows inside the browser
This gives security teams a complete inventory of:
- Who is using AI
- What tools they use
- What data they are sending
No more guesswork.
2. Data Loss Prevention for AI Inputs
BreachFin monitors browser text inputs in real time — without capturing content — and applies DLP rules to detect sensitive patterns such as:
- PCI card data
- PII
- PHI
- Internal code
- Credentials
- Confidential documents
- Financial statements
- Customer information
If a user attempts to paste or upload sensitive data into an AI prompt, the plugin:
- Blocks the action
- Warns the user
- Notifies IT/security
- Logs the event for audit
This closes the largest AI-driven data leakage vector.
3. AI Activity Logging & Audit Trails
Everything AI-related is logged:
- When the user opened an AI tool
- What actions occurred (paste, upload, generate)
- Which extensions or apps were involved
- Policy decisions made (allow/block)
- Risk level at the moment of interaction
This enables:
- Compliance evidence
- Forensic analysis
- User coaching
- Policy tuning
Security teams gain full visibility into AI data paths.
4. Control Unauthorized AI Extensions
The BreachFin plugin detects and regulates:
- High-risk AI browser extensions
- Extensions with clipboard or page-access permissions
- Tools scraping SaaS dashboards
- Unknown apps connecting to corporate data
Policies can automatically:
- Block the extension
- Disable it
- Notify users
- Alert security teams
- Remove access tokens
This eliminates one of the fastest-growing Shadow AI attack vectors.
5. Policy Enforcement Without Blocking Productivity
Security needs balance.
BreachFin’s plugin supports intelligent, context-aware governance:
- Allow general AI usage
- Block sensitive categories
- Restrict specific domains
- Limit uploads but allow text summarization
- Permit approved enterprise AI tools
- Enforce MFA or enterprise SSO for AI tools
This lets developers, support teams, analysts, and business units use AI safely.
Why Browser-Level Control Is the Future of AI Security
Traditional DLP Can’t See AI Interactions
Network DLP? Blind.
Email DLP? Blind.
Endpoint DLP? Mostly blind.
CASBs? Don’t see text pasting.
SIEMs? No logs.
AI usage lives inside:
- Browser tabs
- Extension pop-ups
- In-page text boxes
- Copy/paste events
- Drag-and-drop upload areas
Only browser-level instrumentation can catch these.
Shadow AI is Now a Top Insider Threat Vector
Most data exfiltration today is accidental — not malicious.
Employees simply try to work faster.
AI tools can store or train on uploaded data
And organizations lose control instantly.
Regulators are catching up
PCI DSS, NIST, ISO, SOC2, HIPAA, GDPR — all require strict visibility over third-party processors and data flows.
AI breaks compliance unless monitored.
The Outcome: Safe, Controlled, Compliant AI Adoption
BreachFin’s Browser Security Plugin gives organizations:
✔ Full visibility into Shadow AI usage
✔ Real-time DLP for AI tools
✔ Policy-based control over uploads and prompts
✔ Alerts for high-risk activity
✔ AI extension monitoring
✔ Governance aligned with PCI DSS, SOC2, NIST
✔ Browser-level audit logs
You don’t need to block AI entirely.
You just need to control the risks.
Final Thoughts: AI Adoption Shouldn’t Mean Losing Control
AI will accelerate every business in the world.
But it will also expose every business that fails to govern it.
Shadow AI is the new Shadow IT — faster, riskier, and harder to detect.
The only way to protect your data, customers, and compliance posture is to secure the browser itself.
That’s why the BreachFin Browser Plugin exists:
Real-time visibility. Real-time control. AI-ready DLP for the future of work.
