Your CEO Just Clicked A Phishing Link

So is a real-time email security tool that protects Gmail and Outlook inboxes from sophisticated phishing, spoofing, and malicious emails. Unlike basic email filters, So uses AI to analyse context and behavioural patterns that advanced attacks use to bypass Gmail and Outlook's built-in security. It currently works as a Chrome extension, with a standalone secure mail client launching soon.

Yes — a free account is required to verify your identity and ensure the extension only works on your email account. You'll need to grant access to each email analysis, which will keep you in complete control of the security process.

• Works with Gmail and Outlook Web
• Analyses the subject line and email body for threats using AI
• Displays inline warning banners with threat explanations
• Adds smart labels like Work, Promotional, and Personal for easy categorization
• Requires no special setup — just sign up and install
• Trusted by users protecting their inboxes daily

No. We do not store, transmit, or sell your emails. The extension analyses content only as you view it in your browser. Only anonymised threat patterns are sent to our servers to improve detection — never your actual email content.

Currently, So works as a Chrome extension on desktop and laptop computers with Gmail and Outlook Web. Mobile app and additional browser support are planned for later this year.

Pro pricing will be announced when it launches in late July. Early users who install the free version this month will receive exclusive lifetime pricing when Pro becomes available.

Launching in late July 2025, the Pro version includes:
• Sender verification using SPF, DKIM, and DMARC
• URL and link scanning
• Attachment scanning for malware and suspicious files
• Team dashboards with threat reporting and analytics
• So Mail Client (optional, full-featured secure inbox)

So is ideal for small-to-medium teams who handle sensitive information but don't have enterprise security budgets:
• Real estate teams (protecting client financial data)
• Law firms and clinics (safeguarding confidential communications)
• Nonprofits (preventing donation fraud and data breaches)
• Solo professionals who need protection without IT complexity

Most enterprise tools are expensive and complex. Consumer tools like built-in Gmail security miss sophisticated attacks. So bridges this gap with enterprise-level AI protection designed for everyday users, with simple installation and transparent privacy practices.
