More security tools are slowing down your incident response
Time plays a crucial role in an organization’s defense posture, including the timestamping of events, whether they occurred during business or non-business hours, context, such as after a major business change or during a specific season, and the time taken to detect and respond to incidents.
While most of these time-related factors lie outside security teams’ control, they’re directly responsible for the time it takes to detect and respond to cyberattacks and impacts to the organization’s overall security posture.
When more isn’t merrier
When building a security strategy, more is not always better. More tools, more datasets, and more siloed strategies often result in increased investigation times and reduced efficiency.
The volume of alerts generated by multiple independent tools can also overwhelm analysts and complicate forensic analysis. Although the mean time to detect (MTTD) for individual tools might appear low, the overall time required to correlate events and identify root causes across multiple systems can increase significantly.
From a response perspective, the mean time to respond (MTTR) should be kept as low as possible because delayed responses can amplify the impact of an attack. Cyberattacks can cause both financial and reputational damage. While the effects might not be immediately visible, the cost of an incident typically increases over time as highlighted in IBM’s “Cost of a Data Breach Report 2025.”
Breaking down security silos
Unlike traditional IT environments where employees worked within defined organizational boundaries, today’s digital landscape extends far beyond physical offices and even national borders. This distributed perimeter makes it significantly harder for IT and security teams to monitor devices, activities, and potential threats.
The widespread use of personal devices, shadow IT, and unauthorized applications further expands the attack surface and adds to the challenge.
Modern IT operations cover a broad range of functions, from provisioning devices and managing access permissions to patching vulnerabilities, monitoring user activity, and detecting ongoing threats. To handle this complexity, teams employ specialized tools such as endpoint detection and response, extended detection and response, and network detection and response solutions, along with identity management and other cybersecurity systems.
However, as each new tool enters the stack, achieving centralized visibility becomes more difficult. The volume of logs and alerts generated can be enormous, making it challenging for analysts to prioritize threats effectively.
The most crucial step for any security operations center (SOC) team is to address the silos before attempting to form a complete picture of the organization’s security landscape.
The telecom industry under the microscope
The telecom industry is the backbone of global communication, and therefore must maintain an exceptionally low tolerance for detection delays. When an incident occurs, telecom providers must respond swiftly due to the far-reaching impact on network reliability, customer connectivity, service availability, and national infrastructure. Even a minor delay in detection can lead to widespread outages, degraded performance, and increased exposure to cyberthreats across interconnected systems, making swift response imperative. As a result, reducing MTTD is not just a performance metric for telecom organizations; it is a critical operational requirement that directly influences public trust, regulatory compliance, and the overall resilience of global communication networks.
SIEMulating the SOC
A straightforward solution is to deploy a unified security information and event management (SIEM) platform that can ingest data from multiple sources and integrate with existing tools in the IT ecosystem. Selecting the correct SIEM platform and deployment model is crucial to ensure alignment with organizational needs.
The core benefit of a SIEM solution lies in the visibility and centralized detection it provides. SIEM tools can analyze individual events, detect security incidents based on log data, and trigger automated responses to reduce the overall impact of attacks. This is primarily achieved in three ways:
- Integration with existing tools: SIEM solutions can integrate with various tools through APIs, database connections, or standard data ingestion protocols. Once the data is collected, it is parsed, normalized, and analyzed to provide actionable insights.
- Leveraging threat intelligence: Modern SIEM platforms incorporate external threat feeds and intelligence databases. By correlating internal activity with this intelligence, they can identify known threat sources, detect indicators of compromise, and even uncover data breach indicators from dark web monitoring.
- Using predefined workflows and playbooks: Automated workflows and response playbooks enable faster threat mitigation and ensure consistent incident handling, even during non-business hours.
Bridging SIEM and SOAR for complete automation
While SIEM platforms focus on detection and correlation, security orchestration, automation, and response (SOAR) solutions take the next step by automating incident response actions. By integrating SIEM with SOAR, organizations can automatically trigger workflows such as isolating compromised endpoints, disabling breached accounts, or escalating incidents to analysts with full context. This integration not only reduces MTTR but also helps SOC teams prioritize high-severity threats efficiently. It allows human analysts to focus on strategic decisions instead of repetitive operational tasks.
Another major advantage of a SIEM solution is its ability to operate on top of data lakes, which are storage repositories for large amounts of raw data retained in its native format. By centralizing data from siloed tools into a unified data lake, organizations enable the SIEM solution to perform advanced correlation and analytics at scale. This architecture enhances cost efficiency, scalability, and analytical depth.
However, it also introduces challenges such as data normalization, real-time parsing, and data enrichment, which need to be addressed to ensure accuracy and performance.
Modern SIEM tools also support behavior-based threat detection. They can learn normal activity baselines and identify anomalies, insider threats, and account takeovers before they escalate. In addition, SIEM solutions can map events to the MITRE ATT&CK framework, helping analysts trace tactics, techniques, and procedures used by adversaries across different attack stages.
Ultimately, organizations should select a SIEM solution that aligns with their security maturity level, infrastructure scale, and automation goals.
Toward a more resilient security future
Cybersecurity is a continuous improvement practice, not a one-time implementation. Organizations should have a clear strategy in place and refine it regularly.
A growing trend is the outsourcing of SOC operations to managed security service providers due to the shortage of in-house talent, limited tools, and the expertise external partners bring. However, such decisions should be made carefully, considering the sensitivity of organizational data and compliance requirements.
Security information plays a crucial role in maintaining an organization’s reputation. Any breach or data leak can cause significant financial and reputational harm.
While having more data may seem advantageous, it only becomes valuable when it is analyzed effectively and acted upon. Otherwise, it merely increases storage costs without enhancing security outcomes. The ultimate goal should be to minimize downtime and ensure the continuous availability of crucial resources, supporting the smooth and uninterrupted operations of the organization.
Achieving this requires a focus on reducing MTTD and MTTR. With centralized detection platforms such as SIEM, enhanced with automated response workflows through SOAR, organizations can correlate events from multiple tools, detect threats more quickly, and respond efficiently before incidents escalate. In this way, data becomes actionable intelligence, enabling proactive defense and ensuring that security operations directly support business resilience.
As AI continues to evolve, organizations should leverage its capabilities to enhance threat detection, response automation, and predictive analysis. AI-driven analytics can significantly reduce MTTD by identifying patterns, anomalies, and potential threats faster than traditional rule-based systems.
Similarly, AI-powered automation and decision support can lower MTTR by enabling faster triage, prioritization, and remediation of incidents. Ultimately, cybersecurity is a collaborative effort, and it’s up to the security community to work together, share intelligence, and defend against the evolving threat landscape.
