SOAR vs SIEM: What’s the Difference?

Terms and acronyms can get convoluted in the ever-growing security marketplace. A perfect example is SIEM and SOAR, two terms many people use interchangeably. Although security information and event management (SIEM) and security orchestration, automation and response (SOAR) have capabilities that compliment each other, they are not the same thing. With this in mind, the most successful security operations (SecOps) teams use both technologies to optimize their security operations center (SOC).

At their core, SIEM focuses on collecting, analyzing, and correlating security event data to detect threats in real-time, while SOAR automates and orchestrates incident response workflows, enabling faster and more efficient threat mitigation. Together, they provide a more comprehensive approach to cybersecurity.

What is SIEM?

Firewalls, network appliances and intrusion detection systems generate an immense amount of event-related data – more data than security teams can reasonably expect to interpret. A SIEM makes sense of all of this data by collecting, aggregating, and then identifying, categorizing and analyzing incidents and events. This is often done using machine learning, specialized analytics software, and dedicated sensors.

A SIEM SOC solution examines log data for patterns that could indicate a cyberattack, then correlates event information between devices to identify potentially anomalous activity, and finally, issues an alert accordingly.

So why isn’t a SIEM solution effective on its own?

Before log data is processed by a SIEM, it goes through a series of hand-offs between data aggregation tools. From there, the SIEM then runs analytics and creates an event that needs to be responded to. This data aggregation lifecycle makes threat detection and incident response slower and more expensive than it should be because SIEM isn’t built to respond to incidents – that piece of the security puzzle is still missing.

SIEM tools also typically need regular tuning to continually understand and differentiate between anomalous and normal activity. The need for regular tuning leads to security analysts and engineers wasting precious time on making the tool work for them instead of triaging the constant influx of data.

What is SOAR?

Like SIEM, SOAR tools are designed to help security teams reduce alert fatigue and streamline incident response processes. SOAR platforms take things a step further by combining comprehensive data gathering, case management, standardization, workflow and reporting to provide organizations the ability to implement sophisticated defense-in-depth capabilities.

Here’s how:

• SOAR solutions gather alert data from each integrated platform and place them in a single location for additional investigation.
• SOAR’s approach to case management allows users to research, assess, and perform additional relevant investigations from within a single case.
• SOAR establishes integration as a means to accommodate highly automated, complex incident response workflows, delivering faster results and facilitating an adaptive defense.
• SOAR solutions include multiple playbooks in response to specific threats: Each step in a playbook can be fully automated or set up for one-click execution directly from within the platform, including interaction with third-party products for comprehensive integration.

Put simply, SOAR integrates all of the tools, systems and applications within an organization’s security toolset and then enables the SecOps team to automate incident response workflows.

SOAR’s main benefit to a SOC is that it automates and orchestrates time-consuming, manual tasks, which enables security teams to speed up response times and better use their specialized skills. The result is faster MTTD and MTTR, reduced dwell time, and a higher level of preparedness.

What is the Difference Between SOAR and SIEM? 

	SIEM	SOAR
Primary Purpose	Analyze and aggregate event-related data to identify and categorize potential security incidents.	Automate and orchestrate the security incident response and SOC case management.
Core Functionality	Collects, aggregates, and analyzes log data. Uses machine learning, analytics, and sensors to detect potential threats. Generates alerts for SOAR to remediate.	Gathers alert data from various platforms like SIEM, EDR, XDR, and TIP. Manages cases in from a central console. Initiates automated and adaptive incident response workflows.
Integration	Focuses on collecting data from various network devices and systems.	Integrates all security tools, systems, and applications in an organization to automate incident response workflows.
Incident Response	Limited to alerting on potential incidents based on detected patterns. Does not provide a built-in response mechanism.	Provides a comprehensive response mechanism using playbooks that can be fully automated or manually executed. Generates dashboards and reports on security incidents.
Challenges/Limitations	Slower threat detection due to the lengthy data aggregation lifecycle. Needs regular tuning. Does not inherently respond to incidents. Long term log storage is exepensive.	Documented processes, SOC roles and responsibilities is required for successful SOAR implementation. Doing so can be a challenge and barrier for less established SOC teams.
Primary Users	Security analysts and engineers looking to detect potential cyber threats.	Security teams looking to automate and orchestrate their response to detected threats.
Effect on SecOps	Increases the amount of detectable incidents but might produce more alerts than can be practically responded to.	Enables the security team to efficiently handle a high alert load and focuses them on specialized tasks, resulting in a higher-performing SOC.
