Any URL is verified against threat-intelligence databases.

In Indian tradition, a kavach was the shield worn into battle. Your battles are now digital — and the shield is a message away.

Real examples

Exactly what you'll receive

SCAM
"CBI officer here. Your Aadhaar is linked to money laundering. You are under digital arrest. Stay on this video call and tell no one."

यह "डिजिटल अरेस्ट" स्कैम है। भारत में ऐसा कोई कानून नहीं है — CBI इस तरह वीडियो कॉल पर गिरफ्तार नहीं करती।

→ कॉल काट दें। घर के किसी सदस्य को बताएं। 1930 पर कॉल करें।

SUSPICIOUS
"Your SBI KYC is incomplete. Update in 24 hours or your account will be frozen: sbi-kyc-update.xyz"

The link "sbi-kyc-update.xyz" is not an official SBI domain. Banks never send KYC links by SMS or WhatsApp.

→ Go directly to sbi.co.in or call the number on your bank card to check.

SAFE
"Dear Customer, your Amazon order #408-3746291 has shipped. Track at amazon.in. Delivery in 3 days."

This looks like a genuine Amazon shipping update. The format and link match Amazon's real messages.

→ Safe to track. To be sure, open the order in the Amazon app rather than the link.

Every verdict has the same four parts

The verdict

SCAM, SUSPICIOUS or SAFE — always first, always clear.

The reason

Two short sentences a 65-year-old can understand.

The action

One specific thing to do right now — not a long list.

The note

A one-line reminder that this is guidance, not legal advice.

FAQ

Common questions

Yes, free for individuals, with a fair-use limit of 20 checks per day per person to prevent misuse. We will never charge ordinary users for basic scam checking.
We store only what's needed to run the service — a short preview (up to 200 characters), the verdict, and a hashed identifier for rate-limiting. We never sell your data. Full details are in our Privacy Policy.
Kavach is an awareness tool, not a guarantee. New scams appear daily. If something still feels wrong despite a SAFE verdict, trust your instinct and verify through official channels. Report any miss to help@cyberoak.in so we can improve.
Voice notes aren't supported yet — Kavach will ask you to type what the message said. Voice support is on our roadmap.
Hindi, English and Hinglish. There's no setting to change — just write naturally and Kavach replies in the same language.
Send "I lost money" or "please help" and you'll get emergency guidance immediately. The most important step is to call your bank and 1930 within the first 30 minutes — that's when recovery is most likely.
