Six defense layers · one gateway

Built to stop attacks
your WAF never sees

Traditional security tools protect networks and endpoints. KareriAI Labs protects the newest attack surface — the language your AI speaks.

Products

Choose your protection

Two ways to stay safe — free protection for individuals, full-stack security for teams and enterprises.

01 — Personal

Personal Protection Free

Free, browser-level safety for everyday AI use. Paste, chat and browse with prompts inspected and PII redacted before anything leaves your machine.

  • Browser extension for ChatGPT, Copilot & more
  • Save and Monitor your data before you paste it
  • Automatic PII redaction before you hit send
  • Free forever for individuals
02 — Enterprise

Enterprise AI Security

The real-time AI security gateway for production LLM apps. Four pillars — DLP, shadow-AI governance, agent controls and audit — on every prompt and response.

  • Prompt-level DLP for ChatGPT, Claude, Copilot & more
  • Shadow AI discovery & SSO-gated access governance
  • Least-privilege controls for AI agents
  • Centralized logging, audit trails & policy enforcement
  • Protection from Prompt-Injection attacks
Personal Protection — Data protection

Your data never leaves without permission

Part of our free Personal Protection. Every prompt is checked on-device before it reaches ChatGPT, Copilot or any AI site — sensitive bits masked automatically.

  • 40+ PII detectors — emails, cards, SSNs, API keys, phone numbers
  • Prompt-injection & jailbreak warnings before you send
  • One-click redact — mask, tokenize or block per entity
  • Works where you already chat — no new app to learn
personal — paste guard

Enterprise AI Security

What our enterprise productgets you

Four pillars that cover how your teams actually use AI — from paste to agents to audit.

01

Prompt-Level Data Loss Prevention

Our product inspects and filters what your employees paste into AI tools — ChatGPT, Claude, Copilot, and more — before sensitive data ever leaves your network. Our real-time engine catches PII, source code, credentials, financial data, and confidential documents at the point of entry, giving you protection the AI vendors themselves don't provide.

02

Shadow AI Discovery & Access Governance

Our product gives you full visibility into every AI tool being used across your organization — including the unsanctioned personal accounts, browser extensions, and rogue API keys most enterprises never see. We help you shut down shadow AI and route employees toward approved, contracted tools through SSO-gated access, so every interaction happens under an enterprise data-processing agreement.

03

Least-Privilege Controls for AI Agents

As AI shifts from chat to autonomous action — calling APIs, reading files, executing tasks — our product scopes exactly what data and systems each AI agent can touch. We enforce human approval on sensitive actions and treat every AI service account with the same least-privilege discipline as your human workforce: no standing admin access, rotated credentials, and full audit logging on every call.

04

Centralized Logging, Audit Trails & Policy Enforcement

Our product logs every prompt, output, and tool call in one place, giving you the audit trail your compliance team needs for GDPR, HIPAA, and SOC 2. Our policy engine blocks or redacts data in real time based on your own rules — like preventing customer PII from ever reaching a third-party LLM API — so you're ready for a security review before anyone asks.

Layer 01 — Injection

Prompt Injection Defense

Injections hide everywhere: user messages, uploaded PDFs, scraped web pages, tool responses. KareriAI Labs inspects every token in context and strips hostile instructions before they reach the model.

  • Direct injection in user input and chat history
  • Indirect injection inside documents, URLs and RAG context
  • Delimiter-smuggling and roleplay framing detection
  • Continuously updated against OWASP LLM Top 10

# redaction policy (YAML) redact: entities: [email, phone, card, ssn, api_key] mode: mask # mask | tokenize | block direction: both # inbound + outbound log_safe_copy: true
Layer 02 — Privacy

PII & Secret Redaction

Over 40 entity types recognized out of the box, with custom detectors for your own formats. Redaction happens in both directions — and the safe copy is what lands in your logs.

  • Emails, cards, SSNs, passports, health IDs and more
  • API keys and tokens (OpenAI, AWS, GitHub, Slack formats…)
  • Mask, tokenize or block — per entity, per route
  • GDPR, HIPAA and PCI-DSS friendly by design
Layer 03 — Policy

Policy Engine in plain English

Write rules the way you think. “Never discuss competitors.” “Refuse medical advice.” “Keep responses under NDA topics.” KareriAI Labs compiles them into enforceable guardrails applied on every request.

  • Natural-language rules or YAML — your choice
  • Topic, tone and compliance boundaries per app
  • Version-controlled policies with instant rollback
  • Dry-run mode to test rules against live traffic safely

And the rest of the shield

Data Exfiltration Guard

Response-side scanning catches models leaking system prompts, training data, internal docs or cross-tenant history — even when the attack slipped past input filters.

Jailbreak Detection

DAN personas, base64 payloads, token-smuggling and slow multi-turn manipulation are scored across the whole conversation, not just one message.

Monitoring & Audit

Live attack maps, per-app risk scores, immutable audit trails and alerts into Slack, PagerDuty or your SIEM. SOC 2 Type II report available on request.

Developer-first

One line of code.
Every prompt protected.

Drop the SDK into your stack or route traffic through our gateway. Works with OpenAI, Anthropic, Gemini, Azure OpenAI, Bedrock and self-hosted models.

import { Shield } from "@kareriai/karerialabs"; const shield = Shield.init({ key: process.env.SHIELD_KEY }); const result = await shield.protect(userPrompt); if (result.blocked) { return res.json({ error: result.reason }); // attack stopped } return callLLM(result.safePrompt); // clean prompt only
