Email Security questions

Straight answers on phishing, speed and coverage.

Still unsure? Talk to an engineer

Can email security stop all phishing?

No single layer can. We combine filtering, attachment sandboxing, link checks, impersonation detection and domain authentication. The attacks that still get through are covered by security awareness training.

Will it delay real email?

No. Scanning adds milliseconds. Setup takes one to two business days with zero downtime and no change to how your team sends or receives mail.

Does it work with Microsoft 365 and Google Workspace?

Yes. We set it up for both, with settings tuned to each platform, and connect it to your DMARC and DNS filtering.

What if a phishing email gets through?

We check who received it, pull it from every mailbox and tell the users affected what to do. If someone entered a password or opened a file, incident response starts right away. Most cases are contained within hours.

How does it work with other protection?

Email security works with DNS filtering, EDR and MFA. DNS filtering blocks bad links, EDR stops malware from any source and MFA keeps stolen passwords from working.

Are shared mailboxes covered?

Yes. Shared mailboxes, groups, resource mailboxes and user accounts all get the same filtering. New mailboxes are covered automatically.
