As answered by people managing Phixo and Opalstack.
Phixo's answer
Phixo explains why an email is dangerous instead of just flashing a red warning. Every scan shows the specific evidence — a lookalike sender domain, a link whose destination doesn't match its text, failed email authentication, manipulation tactics in the wording — in plain English, right inside Gmail or Outlook. It's also privacy-first by design: the email body is analyzed in real time and never stored.
Phixo's answer
Most browser security tools protect your browsing in general and treat email as an afterthought. Phixo does one job deeply: it analyzes the actual email you're reading with four layers — a rules engine, live threat-intelligence feeds refreshed every 15 minutes, SPF/DKIM/DMARC authentication checks, and an AI read of the message's tactics. And it's honestly priced for individuals: a free tier with 10 scans a day, and paid plans from $2.99–4.99/month versus the $10–15/month typical of the category
Phixo's answer
Individuals, freelancers, and small teams who handle important email without an IT department behind them — people who get invoices, client requests, and account notices all day and need a second pair of eyes before they click. Deliberately not enterprise: no seat minimums, no admin console, no sales calls.
Phixo's answer
The founder nearly fell for a phishing email — right logo, right wording, cursor already on the "Verify" button before something felt off. The unsettling part wasn't the email; it was realizing that nothing in the inbox explained what to look for. Existing tools either silently filter (and miss the sophisticated ones) or block without teaching you anything. Phixo was built to be the missing explanation: a tool that catches the threat and shows you exactly why, so you get sharper over time instead of staying dependent.
Phixo's answer
Chrome extension (Manifest V3, vanilla JavaScript), .NET 8 backend API, PostgreSQL, React dashboard, LLM-based analysis via Groq, and open threat-intelligence feeds (URLhaus, PhishTank, OpenPhish, ThreatFox).
