Understanding the Value of SIEM and SOAR
At their core, SIEM and SOAR platforms improve visibility and response—two pillars of an effective cybersecurity strategy.
SIEM platforms collect and centralize log data from various systems across an organization. By analyzing this data in real time, SIEMs detect suspicious activity and generate alerts to security teams. This capability supports compliance requirements and provides a clearer picture of what’s happening in your environment.
SOAR platforms take things a step further by automating certain responses to those alerts. Using predefined workflows, or “playbooks,” SOAR tools can isolate compromised devices, trigger alerts, or begin remediation processes automatically. This reduces response time and allows security teams to focus on more complex threats.
Together, SIEM and SOAR platforms help organizations:
- Enhance detection of cyber incidents
- Shorten response time to active threats
- Improve operational efficiency through automation
- Align with frameworks like the Essential Eight and CISA’s Cybersecurity Performance Goals
However, these benefits depend on thoughtful, well-managed implementation.
How SIEM and SOAR Work
A single organization can generate vast amounts of data from endpoints, cloud services, and internal systems. SIEMs act as a central hub, gathering and analyzing this data to identify anomalies—such as unauthorized access attempts or unusual behavior patterns.
If a SIEM identifies potential malicious activity, it raises an alert. The SOAR platform can then respond using automation. For example, it might block a suspicious IP address or disable a compromised user account, based on a set of predefined rules.
Importantly, SOAR doesn’t replace human analysts—it empowers them by handling repetitive tasks and accelerating the overall response process.
Challenges Executives Should Understand
While SIEM and SOAR tools are powerful, they are not turnkey solutions. Two primary challenges stand out:
- Configuring Accurate Alerts
Security teams must identify the right types of data and apply precise rules. If not tuned properly, SIEMs can flood teams with false positives—or worse, miss real threats altogether. - Avoiding Automation Errors
If a SOAR tool acts on false information, it could disrupt legitimate business operations. Careful configuration and testing are essential to avoid unintended consequences.
These platforms also require ongoing oversight, skilled personnel, and regular updates to adapt to evolving threats.
Strategic Implementation Recommendations
1. Assess In-House vs. Outsourced Capabilities
Managing SIEM/SOAR in-house offers more visibility and control but demands significant expertise and staffing. Outsourcing can help fill gaps but requires careful vetting of providers for trustworthiness, data handling practices, and service quality.
2. Be Mindful of Pricing Models
Many SIEMs are priced based on how much data they ingest. Costs can escalate quickly if data volume isn’t managed carefully. Understand pricing structures and monitor ingestion levels to avoid hidden expenses.
3. Invest in Ongoing Training
Technology alone isn’t enough. Cybersecurity teams must be continuously trained to tune, operate, and evolve these platforms effectively.
4. Start with SIEM, Then Layer on SOAR
It’s generally best to establish a well-functioning SIEM before introducing SOAR. Automating a flawed detection process can create more problems than it solves.
5. Regularly Test Platform Effectiveness
As networks and threats evolve, performance must be tested regularly. Consider internal exercises and external penetration testing to ensure platforms perform as intended.
Final Thoughts
SIEM and SOAR platforms can significantly enhance your organization’s cybersecurity readiness. But their success hinges on strategic planning, skilled execution, and continuous improvement. With the right approach, these tools can become a powerful foundation for detecting and responding to the threats that matter most.
