■ Even with M365 measures in place, phishing/BEC cannot be prevented — are you aware of “bypasses”?
Despite using Microsoft 365 or Google Workspace and implementing email security measures, phishing and Business Email Compromise (BEC) attacks are still occurring by bypassing these email defenses.
In particular, cases where authentication information (credentials) are stolen by redirecting users from phishing emails to fake websites, leading to unauthorized account use, are endless.
While such attacks can be significantly suppressed by preventing phishing emails themselves, it is difficult to prevent all of them, and post-bypass countermeasures are essential.
The issue is not whether a “bypass” occurred, but whether “you are noticing suspicious logins or email transmissions that appear afterward.”
■ Are you failing to notice post-bypass signs and falling behind in your response?
Many phishing and BEC attacks exploit legitimate accounts, making them difficult to detect with traditional “prevention” measures alone.
As a result,
・Not knowing which user accounts are experiencing anomalies
・Failing to notice signs such as suspicious logins or email transmissions
Companies often find themselves in situations where incident response and internal explanations are delayed.
Many companies have actually experienced challenges such as “being unable to explain what happened” or “delayed response.”
“Measures are in place, but we’re not noticing” — in this state, risk cannot be said to be under control.
■ Are you aware of what is happening after a bypass? — Organizing criteria for additional countermeasures
In this webinar, we will organize how to combine defense at the phishing email stage with detecting signs of account compromise that occur after a bypass, in order to mitigate damage from account takeovers by phishing/BEC.
In addition, we will present realistic priorities for countermeasures and decision-making criteria on how to visualize signs such as suspicious logins and abnormal email transmissions, and how much understanding is needed to make judgments.
This is not merely a product introduction, but an opportunity to gain insights that clarify “what is unseen” and “where risks remain” in relation to your company’s current situation.
■ Recommended for
・Those who are implementing phishing countermeasures but feel challenged by post-bypass detection
・Those who are not separating phishing email countermeasures from unauthorized account use countermeasures
・Those who have struggled with responding due to failing to notice signs of suspicious logins or email transmissions after a bypass
・Those who are anxious about overlooking signs of account compromise or unauthorized access
・CISOs/IT department heads who are unsure whether current measures are sufficient
・Those who want to explain the necessity of additional countermeasures internally based on specific risks
