The Shortcomings of Legacy SIEM Tools for Security Teams

The Urgent Need for Modern Security Operations Centers in the Age of Rapid Cyber Threats

In today’s digital landscape, organizations face an unprecedented threat from cyber adversaries who can infiltrate and navigate their systems with alarming speed. The average eCrime breakout time—the duration it takes for an adversary to move laterally from an initially compromised host to another host within the victim’s environment—has plummeted to just 62 minutes in 2023. Alarmingly, the fastest observed breakout time was a mere two minutes. This rapid escalation highlights the urgent need for lean, fast, and effective security operations.

The Challenges of Transitioning to Cloud-Based Systems

As organizations increasingly shift to cloud-based systems and adopt new technologies, achieving speed and efficiency in security operations becomes a daunting challenge. Security Operations Centers (SOCs) are tasked with analyzing vast amounts of data to identify and thwart threats. What was once a manageable stream of data has now transformed into an overwhelming ocean, complicating the SOC’s ability to respond effectively.

Legacy Security Information and Event Management (SIEM) systems, which were once the backbone of security operations, are now proving inadequate. These outdated tools struggle to keep pace with the rapid evolution of cyber threats and the sheer volume of data that organizations must process.

The Limitations of Legacy SIEM Tools

Legacy SIEM tools were designed for a time when cyber adversaries operated at a slower pace, and the volume of logs was significantly lower. Today, these tools are too slow, complex, and costly to deliver the critical security outcomes that organizations require—namely, stopping breaches before they escalate.

Setting up and managing legacy SIEM systems is a cumbersome process, often requiring extensive resources and expertise. Their disconnected data flows create additional burdens for SOC teams, making it difficult to respond swiftly to threats. Many of these systems rely on on-premises infrastructure or hybrid setups, leading to high operational costs associated with hardware, maintenance, and labor-intensive deployments. Furthermore, scaling these systems is financially prohibitive due to inherent data fragmentation and ingestion challenges.

The limitations of legacy SIEM tools have given rise to a pressing challenge for security teams: the data paradox. Organizations find themselves caught between the desire to collect extensive data for security purposes and the prohibitive costs and complexities of doing so. This conflict forces security teams to make decisions based on financial constraints, often at the expense of effective security measures. When SOCs are limited in their ability to log and retain data, they create blind spots that slow response times, leaving organizations vulnerable to breaches.

Moreover, legacy SIEMs often force security analysts into the role of "data wrangler," where they spend the majority of their time managing the complexities of SIEM setup and maintenance rather than focusing on meaningful security insights.

Overcoming the Data Paradox with Next-Gen SIEMs

To tackle the challenges faced by modern SOCs, a fundamental shift in how security data is managed and utilized is essential. Enter the next-generation SIEM.

Next-gen SIEMs integrate data, security, and IT with artificial intelligence (AI) and workflow automation, all built into a unified cybersecurity platform. This allows SOC teams to conduct most of their investigative work within a single environment. Built on a cloud-native, index-free architecture, next-gen SIEMs resolve the data paradox by optimizing data ingestion, processing, and storage, ultimately reducing costs and improving efficiency.

As part of a unified AI-native cybersecurity platform, next-gen SIEMs accelerate investigations and facilitate faster detections. Analysts no longer need to pivot between multiple consoles or manually piece together disparate data sources. Key data is readily available within the platform for correlation, eliminating latency and backlogs, which significantly reduces the mean time to detect threats.

The Rise of the AI-Native SOC

The reality is clear: legacy SIEM tools have failed the modern SOC. Their sluggishness, complexity, and exorbitant costs undermine the goals of security teams, who require technology that provides immediate time-to-value while enhancing both functionality and cost efficiency.

Empowered by next-gen SIEMs, the AI-native SOC represents a significant leap forward in cybersecurity operations. These advanced systems transform security operations by scaling to support growing data volumes and integrating high-fidelity threat intelligence from various sources, including identity, endpoint detection and response (EDR), and cloud infrastructure. With advanced analytics and AI capabilities, next-gen SIEMs enable SOC teams to detect and respond to threats with unprecedented speed and accuracy.

Conclusion

As cyber threats continue to evolve and accelerate, organizations must adapt their security operations to meet these challenges head-on. The transition from legacy SIEM tools to next-gen SIEMs is not merely a technological upgrade; it is a critical step toward building a resilient and responsive security posture. By embracing AI-native SOCs, organizations can enhance their ability to detect, respond to, and ultimately prevent cyber threats, safeguarding their assets and ensuring business continuity in an increasingly perilous digital landscape.
