Keeping laptops and other endpoint devices secure is crucial to protecting against endpoint-based attacks. Why Legacy Security Falls Short Traditional perimeter security was built for a very different operating environment. However, the environment has changed. Today’s environment includes remote access, cloud platforms, third-party integrations and employees connecting from virtually anywhere. At the same time, the way organizations operate has shifted, with more cloud usage, remote work and connected systems making the traditional perimeter far less effective. Many legacy tools still rely heavily on known threat signatures, while modern attacks frequently involve legitimate credentials, trusted applications and behavior that initially appears normal. They constantly change, making them harder to detect. AI-assisted phishing and automated attack tooling are also accelerating the pace at which attackers can identify and exploit weaknesses. As a result, endpoints have become one of the most difficult areas to monitor consistently. A single compromised device can provide attackers with access to internal systems, user accounts and sensitive operational data. Financial institutions need security operations capable of detecting and responding to suspicious activity before attackers can move laterally. From Reactive Security to Proactive Defense As institutions recognize the need to shift from reacting to threats to stopping them earlier in the process, endpoint detection and response (EDR) plays an important role. Rather than relying solely on known threat signatures, EDR platforms continuously monitor device activity for indicators such as privilege escalation, unusual access patterns and suspicious process behavior. Identifying threats is only part of the challenge. Many institutions see more alerts than internal teams can realistically manage. Without consistent monitoring and clear response processes, important signals can be missed or delayed. This, in turn, gives attackers valuable time to move further into the environment. Examiners increasingly expect institutions to demonstrate not only that threats are detected, but that response activity is timely, documented and repeatable. Endpoint visibility has become a core operational requirement for both incident response and examiner readiness. To meet these rising demands, institutions must go beyond detection and begin building a more modern, proactive approach to endpoint security. Building a Modern Endpoint Security Strategy The challenge is no longer simply identifying threats but responding quickly when suspicious activity arises. As attack timelines shrink, institutions need security operations that can quickly investigate alerts, isolate compromised devices and contain threats before they spread. But as defenses evolve, so do attackers. They are becoming more sophisticated, using automation and AI to scale their efforts, creating a widening gap between the speed of attacks and the speed at which institutions can detect and respond. Closing that gap requires operational discipline around endpoint security as much as technology. To get started, institutions should focus on a few key priorities. • Gain Full Endpoint Visibility: Ensure you have a clear, centralized view of all devices across your environment, both on premises and remote. After all, you can’t protect what you can’t see. • Maintain a Reliable Patching Program: Unpatched systems can quickly become easy entry points for attackers. A consistent, timely patching program helps close vulnerabilities before they’re exploited. • Adopt Behavior-Based Detection: Move beyond signature-based tools and implement solutions that identify suspicious activity based on behavior, not just known threats. • Enable Real-Time Response Capabilities: Contain threats quickly by isolating compromised devices, stopping malicious processes and limiting lateral movement before damage spreads. • Establish Continuous Monitoring: Threats don’t operate on a schedule, so 24/7 monitoring ensures alerts are investigated and addressed without delay. • Require MFA for All Users: Phishing-resistant MFA helps prevent stolen credentials from becoming an open door to your systems. Enforcing it across all users significantly reduces the risk of unauthorized access. 16 NEBRASKA INDEPENDENT BANKER
