Now's the Time to Evaluate your SIEM
Now’s the Time to Evaluate Your SIEM. Here’s How to Do It.
Are you taking time to evaluate your SIEM? The guide below includes six areas to consider in your evaluation.
The SIEM market is undergoing a period of rapid change with vendors consolidating and technologies transforming. This makes it the right to time to assess whether your current SIEM solution is ready to thwart today’s advanced attacks.
Whether you’re considering a new SIEM vendor, optimizing your current deployment, or preparing for a complete SIEM overhaul, the guide and video below will walk you through the essential questions and actions to perform as you evaluate your SIEM.
Assess if your SIEM is capable of detecting and responding to the latest threats.
It’s important to understand if your vendor is actively innovating and adapting to address emerging threats and vulnerabilities. This includes providing the necessary features and updates to keep pace with the evolving threat landscape.
Start Here:
To find out, delve into your vendor’s roadmap. Does it align with your organization’s security strategy and future needs? Are they investing in crucial areas like cloud security, threat intelligence, and AI-powered analytics? Don’t just stop at the roadmap; scrutinize their threat detection capabilities. Can your SIEM effectively identify and respond to advanced threats like insider threats, zero-day exploits, and sophisticated malware?
In today’s interconnected world, your SIEM needs to ingest and analyze data from a wide range of sources. Evaluate their support for data coming from cloud environments, IoT devices, and mobile endpoints. Finally, ensure your SIEM integrates seamlessly with your existing security infrastructure, including tools such as firewalls, intrusion detection systems, and endpoint security solutions. A well-integrated SIEM is key to amplifying your overall security posture.
Determine if your SIEM can handle the volume and complexity of your security data.
Your SIEM needs to efficiently orchestrate, ingest, process, and analyze logs without performance issues or excessive costs, especially given the exponential growth of data.
Start Here:
Take a hard look at your data ingestion costs. Are you paying a premium for data volume? Are you able to optimize costs by filtering and routing data? Explore alternative pricing models that might better align with your needs and budget. Next, evaluate your SIEM’s scalability. Can it handle future growth in data volume and complexity without requiring significant hardware upgrades or architectural changes?
A key function of any effective SIEM is its ability to filter and prioritize alerts. Assess if your system is effectively reducing noise and highlighting critical security events. Are you drowning in false positives, or can your SIEM pinpoint the true threats? Data normalization and correlation are also essential. Can your SIEM effectively normalize data from different sources and correlate events to identify patterns and anomalies that might signal an attack?
Maximize the use of your SIEM for threat detection, incident response, and compliance.
You need to be leveraging the full potential of your SIEM across all relevant security functions.
Start Here:
Begin by thoroughly reviewing your SIEM’s rule set. Are you relying solely on out-of-the-box rules, or have you customized them to your specific environment? Are these rules optimized for efficiency and effectiveness? Next, assess your incident response workflows. Does your SIEM provide centralized automation capabilities to streamline incident response processes, enabling your team to react swiftly and decisively to security incidents?

Evaluate your reporting and compliance capabilities as well. Can your SIEM generate comprehensive reports for compliance audits and regulatory requirements? In today’s environment, user and entity behavior analytics (UEBA) is essential for detecting insider threats and compromised accounts. Determine if your SIEM has robust UEBA capabilities to identify anomalous user behavior.
Confirm your SIEM can effectively secure your cloud environments.
As your organization increasingly relies on cloud services and infrastructure, your SIEM needs to adapt.
Start Here:
Evaluate your SIEM’s cloud security features. Does it offer native support for major cloud platforms such as AWS, Azure, and GCP? Can it monitor cloud-specific threats and vulnerabilities? Next, assess its ability to ingest and analyze cloud logs. Can your SIEM seamlessly integrate with cloud logging services and analyze data from various cloud resources?
Consider your deployment options as well. Can your SIEM be deployed in the cloud, on-premises, or in a hybrid environment? Which deployment model best suits your organization’s needs and budget? Finally, evaluate its security and compliance in the cloud. Does your SIEM meet relevant cloud security standards and compliance requirements such as SOC 2 and ISO 27001?
Uncover the total cost of ownership for your SIEM, including hidden expenses.
It’s important to understand all costs associated with your SIEM, beyond just the initial licensing fees.
Start Here:
Analyze your SIEM’s total cost of ownership (TCO). This should include not just the licensing fees but also factors including hardware costs, software upgrades, personnel training, and ongoing maintenance. Evaluate your vendor’s support and maintenance offerings. Are they responsive and helpful? Do they offer flexible support options that align with your needs and budget?

Assess the need for professional services. Will you require assistance with SIEM deployment, configuration, or ongoing management? Finally, consider the cost of customization and integration. How much will it cost to customize your SIEM’s rules, dashboards, and integrations to meet your specific requirements?
Measure the impact and value of your SIEM
Now that you’ve evaluated your SIEM across these key areas, it’s time to make informed decisions about its future.
Start Here:
Based on your evaluation, consider whether your current SIEM truly meets your organization’s needs. Should you stick with your current SIEM and optimize its deployment, or is it time to explore alternative solutions? To make this decision, research leading SIEM vendors and compare their offerings to your current solution. Pay close attention to features, capabilities, pricing models, and any areas where your current SIEM may be lacking.
Ask yourself if a new SIEM could offer advantages like improved threat detection, reduced costs, enhanced scalability, or better integration with your security infrastructure. If you’re considering a switch, carefully evaluate the migration process. How complex and time-consuming would it be to migrate to a new SIEM? What are the potential risks and challenges? To get buy-in from key stakeholders, develop a clear business case for any proposed changes. Outline the costs, benefits, and risks associated with switching to a new SIEM or optimizing your existing deployment.
Conclusion: Don’t just react – anticipate and mitigate threats as you evaluate your SIEM.
In today’s dynamic threat landscape, a SIEM is no longer a “set it and forget it” solution. Periodic evaluation is essential to ensure your SIEM is aligned with your organization’s evolving needs and capable of defending against increasingly sophisticated attacks. By proactively assessing your SIEM’s capabilities, performance, and cost-effectiveness, you can move beyond simply reacting to incidents and instead anticipate and conquer threats before they impact your business.
