As cyber threats become more sophisticated, organizations are increasingly challenged to protect their digital assets. To defend against these dangers, many companies either partner with Managed Security Service Providers (MSSPs) or establish internal cybersecurity teams. However, despite these precautions, cyber risks continue to persist — and in some cases, grow even more severe.
There are three key reasons why organizations continue to face significant cyber risks, no matter which security strategy they adopt:
- An over-reliance on defensive tooling
- Diminishing efficacy of detection rules
- The underutilization of innovative proactive technologies
Let's explore each of these challenges and understand why they are crucial to tackle in today's evolving threat landscape.
The Current Landscape
Many companies, whether using an MSSP or an in-house security team, rely heavily on defensive tools such as firewalls, multi-factor authentication (MFA), endpoint detection and response (EDR) systems, and vulnerability management programs. While essential, these tools often create a reactive approach that struggles to keep up with evolving threats.
Attackers are well-aware of standard defenses and tailor their techniques to evade them. For example, while patch management and firewalls are critical, they offer limited visibility into post-exploitation tactics once an attacker is inside the network. Vulnerability management tools often generate lists of weaknesses without preventing sophisticated attacks like those exploiting zero-day vulnerabilities. Moreover, many defenses rely on signatures of known threats, missing more subtle, abnormal behavior.
Traditional approaches are static and unable to adapt quickly to the dynamic nature of cyberattacks. Without proactive measures, organizations may not fully realize whether their defenses are truly effective.
EDR Vendors Cutting Detection Rules
Endpoint Detection and Response (EDR) tools are often promoted as a top solution for real-time threat detection. However, many EDR vendors are quietly reducing behavioral detection rules to lower false positives and boost accuracy claims. The data shows that more threats are bypassing these tools, as evidenced by breach and attack simulation (BAS) results. While this may make EDR products more appealing to buyers, it also increases the risk of missing critical threat behaviors.
A similar trend is seen with Managed Detection and Response (MDR) services, which shift responsibility back to clients by claiming that only they understand user behavior patterns. This reduction in detection capabilities makes EDR and MDR solutions less effective in spotting subtle threats, including insider attacks. Although reducing alerts might ease cybersecurity teams' workload, it also creates blind spots in threat detection.
As attackers grow more sophisticated, narrowing detection coverage to avoid noise provides them with a tactical advantage, leaving organizations exposed to critical risks.
Challenges with Reactive Security Tools
A major challenge is the insufficient investment in innovative security technologies that take a proactive stance. Tools like anomaly detection, adversarial threat validation (BAS), and Attack Surface Management offer advanced threat detection capabilities beyond traditional defenses.
Anomaly detection uses machine learning to identify unusual patterns, potentially spotting threats before they fully develop. Adversarial threat validation simulates advanced attacks to test defenses in real-world scenarios, revealing weaknesses that static vulnerability management tools might miss. These proactive technologies help organizations move from a reactive to a preventative security approach, providing clearer insights into the effectiveness of their defenses.
Moving Towards Proactive Defense
To stay ahead of cyber threats, organizations should integrate both defensive and proactive strategies. Traditional defensive tools alone are insufficient against evolving threats, especially when they suffer from reduced detection capabilities. Investing in proactive solutions like anomaly detection and adversarial threat validation helps test and enhance security measures, providing critical insights and identifying gaps.
Anomaly detection monitors deviations in network and user behavior to catch potential threats early, while adversarial threat emulation replicates real-world attacks to evaluate defenses. These approaches improve an organization’s ability to detect and respond to sophisticated attacks and insider threats.
