Questions & Answers

As answered by people managing Nullstack and SafeBrowz.

What's the story behind your product?

SafeBrowz's answer:

SafeBrowz started after watching too many people โ€” friends, family, strangers on Twitter โ€” lose money to scams that were obvious red flags in hindsight. Fake login pages. Drained wallets. ClickFix commands pasted into PowerShell.

Traditional antivirus missed almost all of it because modern scams happen inside the browser, not on disk. Browser safety tools like Avira and Malwarebytes only caught English-language scams from well-known brands, leaving most of the world exposed.

The goal was simple: build one extension that catches scams across any brand, any language, including Web3 โ€” and keep it affordable enough that a regular person would actually install it.

What makes your product unique?

SafeBrowz's answer:

SafeBrowz combines three detection layers in one extension:

  • Local pattern matching catches known scam patterns instantly, offline, with zero latency
  • Server-side URL reputation checks against a live threat database updated continuously
  • AI content analysis reads the actual page and identifies brand impersonation across 420+ brands in 100+ languages

Most competitors rely on blocklists that lag 24-48 hours behind new scams. SafeBrowz's AI layer catches brand-new phishing sites the moment they go live, in any language, even if the domain has never been seen before.

It also specifically targets Web3 threats โ€” wallet drainer scripts, fake Ledger pages, ClickFix pastejacking attacks โ€” that traditional antivirus and browser safety tools miss entirely.

Why should a person choose your product over its competitors?

SafeBrowz's answer:

  • Broader coverage โ€” 420+ brands tracked vs competitors' 20-50
    • Multi-language โ€” works in 100+ languages; most competitors are English-only
    • Web3-aware โ€” actively blocks crypto wallet drainers, fake Ledger sites, and signature phishing; tools like Avira and Malwarebytes don't
    • No bloat โ€” single extension, under 2MB, no companion app, no VPN upsell, no "deals while you shop" ads
    • Fair pricing โ€” $14.99/year for 3 devices. Most competitors charge $30-60/year for one device
    • Privacy-first โ€” we only send the URL you visit, not your history, cookies, or identity

How would you describe the primary audience of your product?

SafeBrowz's answer:

SafeBrowz is built for three overlapping audiences:

  1. Crypto users โ€” anyone holding a wallet (MetaMask, Phantom, Ledger) who needs protection against wallet drainers, fake token sites, and seed phrase phishing
  2. Everyday browsers โ€” people who get phishing emails impersonating Microsoft, banks, or couriers and want a safety net before clicking
  3. Non-English speakers โ€” users who browse in Hindi, Spanish, Portuguese, Arabic, or any of 100+ languages that most security tools ignore

Typical user: someone who has been scammed or almost scammed once, and doesn't want it to happen again.
