Why Gmail and Outlook Still Miss Modern Phishing
Traditional filters stop spam. Modern phishing attacks are designed to look legitimate and bypass automated defenses.
- Personalized messages targeting specific employees
- Context-aware emails that reference real projects or vendors
- CEO impersonation attacks requesting urgent wire transfers
- Vendor impersonation with fake invoices and payment links
- Fake login portals mimicking Microsoft, Google, or your bank
- Business email compromise attempts over multiple messages

Why We Built Inboxguard
Modern phishing attacks bypass traditional filters every day. They're personalized, context-aware, and designed to exploit human trust — not technical vulnerabilities.
Most businesses aren't compromised through software bugs. They're compromised through a single employee clicking the wrong link at the wrong time.
Inboxguard was built to become the final layer of protection before a dangerous click occurs — giving every team member the intelligence to stop an attack before it starts.
Frequently asked questions
Never. Our risk engine runs locally on your device. It analyzes structural patterns, link configurations, and domain metadata without ever sending the content of your messages to our servers.
One Click Can Cost Everything.
Protect your inbox before the next phishing attack reaches your team.
