Equip every security engineer to protect their company from email threats.

SucuriLabs exists to make human communication safer. We do that by protecting people from malicious emails.

What we're building

We believe security engineers should be able to understand why an email is suspicious and do something about it, without spending half their day piecing together evidence.

We combine investigation and response in one product. This avoids a ton of work switching between tools, copying message details around, and trying to work out what happened to an email after someone took action on it.

Who we build for

We build for security and IT teams at companies using Microsoft 365. They receive phishing reports, check suspicious messages, and decide what to quarantine or restore.

They should be able to check the evidence and override a verdict, rather than having to take our word for it.

How we work

This handbook simply explains how we work. We made it public to be transparent about how we build SucuriLabs and to share what we learn with others.
