How AIovert Prevents AI Data Leaks and Keeps Companies Compliant

Personal data, intellectual property, source code, and live API keys all leave the company the same way — pasted into an AI tool. Here is exactly how AIovert stops each one, and the laws it makes you compliant with.

Quick answers

What does AIovert actually do?

It runs in the employee's browser and classifies any text or file the instant it is pasted, dropped, or uploaded into an AI tool. If it contains sensitive data, the action is cancelled on-device — nothing leaves the machine — and only a classification label and a one-way hash are logged.

Which laws does it help with?

GDPR (Articles 6, 9, 28, 30, 32, 35, 44, 83), the EU AI Act (Articles 4, 12, 13, 14, 50), and DORA (Article 9) for financial entities. It provides both the technical control and the audit evidence each one expects.

What kinds of data does it protect?

29 categories — personal data and special-category data, financial identifiers (IBAN, cards), credentials and API keys, source code and internal paths, and contract/NDA language — across ChatGPT, Claude, Gemini, Copilot, Grok and 18 other AI tools.

The leak happens in one place: the input field

Your existing DLP was built for email, cloud storage, and endpoints. None of it can see what an employee types or pastes into a chat box at chatgpt.com. The connection is TLS-encrypted, so a network filter sees an opaque tunnel; the data is gone the moment the employee hits enter. That single moment — the paste — is where almost every AI data leak originates, and it is the only place a control can reliably stop it.

AIovert is a browser extension that sits at exactly that point. It classifies the content on-device, before anything is transmitted, and cancels the paste, drop, or file upload when it contains sensitive data. Because the classification happens locally, the raw content never leaves the browser — only a label (e.g. SSN, API_KEY_OPENAI), the tool's domain, a one-way SHA-256 hash, and the user's work email are recorded.

The specific laws AIovert helps you comply with

Compliance is not a policy document — it is a technical control plus evidence that it works. AIovert provides both, mapped to the obligations that actually apply when staff use AI tools.

GDPR

  • Article 32 (security of processing): blocking sensitive data at the input field is the "appropriate technical measure" the article requires. A written ban is an organisational measure; on its own it isn't "appropriate" when one click can exfiltrate a full customer record.
  • Article 28 (processors): pasting a customer record into a consumer AI tool turns that provider into an undocumented sub-processor with no data-processing agreement. AIovert keeps personal data out of unsanctioned tools entirely.
  • Article 6 & 9 (lawful basis & special-category data): data shared for support was never given a lawful basis for AI processing; health and similar data have a higher bar. AIovert detects special-category indicators and stops them at source.
  • Article 44 (international transfers): most LLM providers are US-hosted, so a paste is often an international transfer with no safeguards. Blocking it removes the transfer.
  • Articles 30 & 35 (records & DPIA): the append-only event log is your record of processing, and the Compliance Hub ships pre-built DPIA templates in four languages.
  • Article 83 (penalties): the worst breaches carry fines up to €20M or 4% of global turnover. The control is trivially cheaper than one incident.

EU AI Act

  • Article 4 (AI literacy): the in-the-moment explanation shown when a paste is blocked is continuous, evidenced AI-literacy training — far stronger than an annual slide deck.
  • Article 12 (record-keeping): automatic, tamper-evident logging of every AI-data event, without storing content.
  • Articles 13 & 14 (transparency & human oversight): usage is disclosed and a human stays in the loop; AIovert assists, it never decides.

DORA (financial entities)

Article 9 requires ICT risk-management controls over data in use. AIovert detects IBANs, SWIFT/BIC, and policy numbers and blocks them before they reach an AI tool, with the exportable audit trail an examiner expects.

Preventing personal-data leakage

The most common leak is mundane: an agent pastes a customer email to draft a reply, or a recruiter pastes a CV to summarise it. AIovert detects names, emails, phone numbers, addresses, national IDs, NHS numbers, card numbers, and IBANs — with checksum validation (Luhn, IBAN mod-97, NHS mod-11) to keep false positives near zero — and offers a one-click masked copy ([NAME], [IBAN]) so the employee still gets their AI draft without exposing a single identifier.

Protecting intellectual property and source code

IP leaves quietly. An engineer pastes a proprietary function to refactor it; a lawyer pastes contract terms to simplify them; a strategist pastes an unreleased roadmap. Once that text is in an AI prompt, it may be retained for model training and can never be retrieved. AIovert recognises source code, internal file paths, and contract and NDA language, and blocks it before it is sent. It also scans attached files — DOCX, PDF, and CSV — extracting and classifying their contents on-device, so a confidential document can't be uploaded under the radar.

Stopping stolen API keys — and the bill that follows

This one is expensive in a way teams underestimate. Developers paste stack traces, .env files, and config blocks into ChatGPT to debug — and ship live secrets to a third party. A leaked OpenAI or Anthropic API key is not just a credential exposure: an attacker who finds it can run inference against your account until the rate limit or your budget is exhausted, leaving you with a four- or five-figure bill for tokens you never used. The same is true for AWS keys (compute spun up on your account), Stripe keys, and GitHub tokens (source-code access).

AIovert detects these secret patterns on-device — OpenAI (sk-), AWS (AKIA/ASIA), GitHub (ghp_), Stripe, Google, Slack tokens, JWTs, and PEM private keys — and cancels the paste before the key leaves the browser, logging the near-miss so security can rotate the credential. The key never reaches the AI tool, so it can't be harvested, and the surprise invoice never arrives.

Other cases it covers

  • Healthcare: discharge notes and patient identifiers (GDPR Art. 9, NHS numbers) blocked before they reach an AI tool.
  • Financial services: client portfolios, deal terms, and MNPI kept out of consumer AI tools, with a supervision-grade log.
  • Customer lists: a pasted CSV of contacts (an Art. 28 trigger) is caught as a bulk export, not 200 individual emails.
  • Crypto: wallet addresses and private keys (ETH, BTC WIF) are recognised and blocked.
  • Shadow AI discovery: tools you never approved are surfaced the first time an employee uses them, so the blind spot closes.

Deploy in 15 minutes, prove it forever

AIovert force-installs via Google Workspace or Microsoft Intune — no proxy, no SSL inspection, no employee action. Within minutes you have on-device blocking across 23 AI tools and a regulation-tagged audit log your DPO can export to CSV, JSON, or a SIEM. The control is the protection; the log is the proof.

The fastest way to see it is to watch it once: paste a realistic (fake) record into the free AIovert paste test and see the data it flags, the redacted version it would send instead, and the exact articles at stake — all in your browser, nothing uploaded.
