Post-Delivery Phishing Remediation for Gmail & Google Workspace

Standard email security filters cannot stop every phishing attack, especially sophisticated or zero day campaigns that reach user inboxes. GAT Labs helps Google Workspace admins investigate, audit, and remove malicious emails across the domain with centralized Gmail visibility, bulk remediation capabilities, and controlled approval workflows designed for post-delivery phishing response.

The Growing Gmail Phishing Risk for Google Admins

Modern phishing attacks are designed to bypass Gmail security filters, allowing malicious emails to reach user inboxes even in well-configured Google Workspace environments.

  • Advanced Gmail Phishing & Zero Day Attacks
  • Limited Visibility Across User Inboxes
  • Slow, Manual Phishing Email Removal
  • User Reliance and Phishing Fatigue

One missed email can result in massive financial loss, regulatory penalties, and long-term brand damage.

Google Workspace admins need a solution that can detect, remove, and respond to phishing emails across the entire domain.

Frequently Asked Questions

Gmail Phishing and Remediation

Can a Google Admin delete a phishing email from a user's inbox after it's delivered?

Yes. Google Workspace admins can investigate and remove malicious emails after delivery, but managing phishing remediation across large environments can be time-consuming. GAT+ helps admins search for suspicious emails across the domain, audit affected inboxes, and perform bulk remediation actions to reduce phishing exposure after an email reaches user mailboxes.

What is a Gmail 'Zero-Day' attack and how do I stop it?

A Zero-Day attack uses a new phishing method that standard filters haven’t learned yet. Because these emails reach the inbox, the best defense is Post-Delivery Remediation. GAT+ allows you to find these emails as soon as they are reported and pull them back from every user’s mailbox before they can cause damage.

What’s the best way to audit Gmail activity in Google Workspace?

GAT+ gives you full visibility into inbound, outbound, and internal Gmail. You can filter, export, and report on message metadata, content, attachments, and user actions by OU, group, or user.

Does GAT Labs block phishing emails before they reach inboxes?

No. GAT Labs focuses on post-delivery auditing, investigation, and remediation, giving Admins visibility and control over phishing emails that bypass filters.

Can I set up automated responses to phishing emails?

You can set up alert-based workflows with GAT Flow to automatically suspend compromised accounts, notify Security Officers, or trigger follow-up actions, but email deletion can be done using the GAT Unlock feature in GAT+, which still requires security officer approval. With the GAT Unlock pre-approval option, the process can be expedited and risk mitigated faster.
