Real Messages, Real Risk
Scams Don't Look Like Scams.
The most dangerous scams look ordinary.
“Your KYC expires today. Verify now.”
“Your parcel is waiting.”
“You won ₹50,000.”
“Your electricity will be disconnected.”
“Your refund is ready.”
“Scan this QR to receive money.”
Four Ways Arjuna Protects You
One shield, four kinds of protection.
Scam Protection
Suspicious links, phishing websites, and scam messages on WhatsApp and SMS.
02Payment Protection
Fake QR codes, spoofed payment links, and UPI fraud.
03Device Protection
Fake apps, sideloading, root/jailbreak risk, and screen-sharing scams.
04Family Protection
Simple, real-time protection for parents, seniors, and everyone you share a phone plan with.
How Arjuna Works
Detect. Explain. Protect.
Detect
Arjuna checks the links, QR codes, apps, or device-risk signals a feature is designed to look at.
Explain
You get a plain-language reason, not just a red flag — for example, "This website appears to imitate a financial service and may attempt to collect sensitive information."
Protect
Depending on the feature, Arjuna warns you, blocks the action, or guides you toward a safer next step.
Arjuna helps you stop before you trust — before a link can cost you, before a fake app can spy on you, before a scam becomes a loss.
