Stop phishing across Email, Slack, Teams, and other collaborative apps.

Our Mission

Stop phishing where it happens

Phishing has evolved beyond email. Attackers now target Slack, Teams, and every communication channel where trust is high and defenses are low.

We're building the detection layer that modern communication needs—AI-powered, real-time, and designed for the platforms your team actually uses.

BEC Emails Targeted Monthly

Phishing isn't just email anymore.

The attack surface has expanded. Your defenses should too.

Chat-based social engineering

Attackers increasingly target Slack and Teams where defenses are weakest and trust is highest.

Links moving fast

Malicious URLs spread quickly through chat channels before traditional tools can catch them.

Alert fatigue

Security teams are overwhelmed. Real threats get lost in noise from disparate tools.

Protection where your team communicates

One extension. Three major platforms. Complete coverage.

Email

Detects suspicious messages and risky links across all major email platforms.

Slack

Monitors channels and DMs for phishing attempts and malicious URLs in real time.

Microsoft Teams

Protects your Teams conversations from social engineering and dangerous links.
