Webinar Held: "What EDR-centric Endpoint Detection Alone Cannot See: How to Catch Precursors of Evasion Attacks" for Companies with 500+ Employees
A webinar will be held for companies with 500 or more employees, focusing on detecting precursors of cyberattacks that EDR alone might miss, using SIEM-based MDR for proactive response. It will explain the importance of highly accurate detection and rapid incident response through log correlation analysis across the entire environment, in response to the normalization of ransomware attacks.

■ "Preemptive" Operations Become a Management Issue with the Normalization of Ransomware Breaches
With the sophistication and diversification of attacks, including ransomware, the era has come where preparations are made on the premise that breaches "will happen," not "will not happen." For companies with 500 or more employees, IT environments are becoming more complex, encompassing multiple locations, cloud, SaaS, and network devices. It is difficult to grasp the overall picture by individually tracking detections from each tool. There is a demand for an operational design that re-connects fragmented precursors as an "attack flow" to contain them in an early phase. Moving beyond reactive responses, the concept of "Preemptive Cybersecurity"—anticipating the attacker's next move based on predictions derived from one's own environment and proactively setting up defenses—is gaining importance from the perspective of business continuity and accountability.
■ EDR-centric Monitoring Fails to Connect Signs Outside the Endpoint
While EDR is being introduced in many organizations, monitoring designs centered on endpoint detection make it difficult to connect with peripheral events such as network, authentication, cloud, and email to grasp the "attack flow," leaving a risk of missing precursors of evasion attacks. Furthermore, as alerts increase, more effort is absorbed in prioritization and initial investigation, making continuous 24/365 monitoring difficult, including nights, holidays, and overseas bases, which can delay the next step even after detection. As a result, this directly leads to operational challenges such as "unable to fully utilize after introduction" and "inflated costs due to duplication of multiple services."
■ Achieve High-Precision Detection and Immediate Incident Response with SIEM-based MDR
In this seminar, we will explain practical points for visualizing fragmented signs as a single attack flow by correlating and analyzing logs from the "entire environment," including networks, with SIEM as the core, without relying solely on EDR-centric endpoint detection. A key feature is that SIEM-based approaches can leverage all information as evidence, making it easier to achieve high detection accuracy and accelerate initial response by speeding up decision-making. With Rapid7's SOC providing 24/7 monitoring, detection, and response support, we will implement a "seamless operation" that connects detection directly to incident response in a practical, on-site manner. Additionally, we will touch upon the concept of Exposure Management as a "pre-stage" to detection and response. This involves understanding exposures such as vulnerabilities and misconfigurations scattered across the entire attack surface of the environment, prioritizing and mitigating risks that are easily exploited by attackers, thereby clarifying "where to address first" and organizing practical insights to enhance the accuracy of proactive measures.
