■ AI-sophisticated phishing leads to increased false positives and quarantines, overwhelming recovery efforts on-site
Phishing attacks are becoming increasingly sophisticated year by year with the use of AI, leading to more cases where suspicious emails, which would have been distinguishable in the past, arrive with more natural wording, seemingly legitimate senders, and confusing links.
As a result, existing email countermeasures tend to err on the side of caution, leading to an accumulation of quarantined emails. What's more troublesome is that even business-critical emails are falsely detected and quarantined, leading to requests from the field to "restore" them. The more quarantines there are, the more likely it is for legitimate emails to be overlooked or delayed, and IT departments tend to be overwhelmed by "post-quarantine handling."
■ Manual confirmation, judgment, and recovery of 'restore' requests create a bottleneck
The process that often gets stuck in quarantined email operations is what happens after a "restore" request comes in. Receiving a request, finding the email, checking its content, sender, links, and attachments, deciding whether to restore it, restoring it, and then contacting the user—if this entire process remains manual, it quickly becomes unmanageable as the number of requests increases.
If judgment becomes individualized or confirmation procedures vary, maintaining service quality also becomes difficult, intensifying dilemmas such as "emails that shouldn't be stopped are stopped" and "the risk of restoring dangerous emails is scary." As a result, quarantined emails accumulate, responses are delayed, and there's no time to consider fundamental solutions—this "accumulation of operations" becomes a bottleneck.
■ Explaining how to design operations to automatically sort quarantined emails using AI judgment and prevent backlog
This seminar assumes a situation where "restore" requests for quarantined emails cannot be kept up with. It will organize the operational design for leveraging AI judgment to automatically sort quarantined emails and streamline the manual process of deciding whether to restore them.
The key is not simply to introduce AI, but to specifically design "what to automate and what humans should judge," "how to handle exceptions," and "how to build a flow that prevents backlogs." Through demonstrations, we will explain how to break the structure that causes post-quarantine processing to accumulate and how to improve daily operations while running them.
■ Recommended for people like this
- Those whose "restore" requests for quarantined emails are increasing, and who cannot keep up with confirmation and recovery.
- Those who are caught between false positives and bypasses, and whose restore judgment is becoming individualized.
- Those whose quarantined emails are accumulating, causing business impact and user dissatisfaction.
- Those who want to reduce manual restore operations and organize a design to lower the operational load.
- Those who want to change their post-quarantine processing to a "non-accumulating" operation using AI judgment.

FAQ
What does "AI-sophisticated phishing attacks" mean?
It means AI generates natural-sounding texts and seemingly legitimate senders, increasing suspicious emails that are difficult to distinguish with traditional measures.
What are the challenges with "quarantined email recovery work"?
The challenges include manual confirmation, judgment, and recovery not keeping up, leading to delays for essential business emails and increased burden on IT departments.
What key operational design points can be learned from the webinar?
You can learn specific strategies for balancing AI-driven automatic sorting with human judgment, handling exceptions, and building flows that prevent backlogs.
