What is Sphinx Email Protection?
Traditionally, email is the hardest component to secure in a company’s IT infrastructure. The good news? If you got to this page by clicking a banner in your email, your company has implemented Sphinx Email Protection!
We’re making email threat detection easier. Sphinx Email Protection uses AI to identify risky emails and places the following banners at the top of your email to let you know how much caution to take:
Gray:
The email does not appear to be malicious, phishing, or spam. Sphinx Email Protection also notifies you if the sender is within your company (Internal) or outside your domain (External).
Yellow:
The email is suspicious: it could be spam, phishing, or contain malicious content. You should be extraordinarily careful about clicking on links or opening any attachments.
Red:
The email is confirmed to be spam, phishing, or contain malicious content – Do not click links, open attachments, or reply to the sender with any confidential or personal information.
Aside from these banners, your email is not altered in any way, so formatting and other features appear exactly the same as before. If you think Sphinx Email Protection isn’t accurately reporting email risks of an email, click the “report email” link below the banner and let us know why. This improves our algorithm and transforms YOU, the user, into a part of the security team.
Sphinx Email Protection doesn’t replace standard security awareness.
While it can make your company safer, Sphinx Email Protection is only one tool in the fight against spam, phishing, and malicious emails. Always remember your Security Awareness Training and apply it to every email you receive. Sphinx Email Protection cuts through the clutter, making it easier to determine if an email is safe or dangerous: it’s a great resource when paired with your security awareness.

Frequently Asked Questions
A yellow banner indicates that Email Protection found something unusual about the email message. It is not necessarily phishing or dangerous, but something you should be aware of. For example, a request for sensitive personal information should be given extra scrutiny. Mail that seems out of the ordinary or is spammy in some way may receive a yellow banner.
A red banner indicates that Email Protection thinks the message is suspicious and likely to be phishing or dangerous in some other way. This includes brand impersonations (e.g., a fake “account alert” email from your IT department), blacklisted phishing URLs, or attempts to spoof mail to look like it came from an internal company account.
This will take you to a web form where you can indicate that the message is truly Safe, Spam, or Phishing. You can also provide a comment describing your assessment. This feedback is used to automatically improve Email Protection’s predictions in the future. Your submissions are also manually reviewed to improve the overall system and ensure Email Protection provides the most accurate security possible.
