Splunk vs. IBM QRadar

Splunk Enterprise Security enables you to realize comprehensive visibility, empower accurate detection with context, and fuel operational efficiency. Detect what matters, investigate holistically, and respond rapidly. The only SIEM solution named a Leader across three major analyst reports.

data access challenges limit visibility

IBM QRadar

Data access challenges limit visibility

Security teams using QRadar SIEM are unable to quickly and easily add and update data sources. This results in data silos and blind spots in the security operations center (SOC). Making it easy and flexible to access data for your SIEM is critical for full visibility.

Splunk's Advantage

Splunk Enterprise Security is an industry-defining SIEM with assistive AI capabilities that offers unmatched, comprehensive visibility by seamlessly ingesting, normalizing, and analyzing data from any source —- at scale. You have the flexibility to selectively ingest crucial data, including at the edge, and benefit from cost-effective storage.

lacks critical advanced capabilities

IBM QRadar

Lacks critical advanced capabilities to reduce Mean Time to Resolve (MTTR)

IBM QRadar falls short on collaboration capabilities that security teams need to quickly detect, investigate and respond to threats. This could include having multiple analysts working together on a common investigation in order to reduce Mean Time To Respond (MTTR). It is common for teams to have email or identity specialists, who can collaborate with the primary analyst.

Splunk's Advantage

With Splunk Mission Control, bring order to the chaos of your security operations by enabling your SOC to detect, investigate and respond to threats from one modern and unified work surface. See Mission Control in action. Take a look at this video today.

lacks third-party integrations

IBM QRadar

Lacks third-party integrations

IBM QRadar SIEM is not compatible with many of the leading third-party SOAR and NDR solutions, identified as a weakness according to industry analysts. QRadar’s 600 third-party integrations pale in comparison to over 2,800 with Splunk.

Splunk's Advantage

Splunk has a vibrant ecosystem of partners and developers. We embrace an open community, giving our customers the freedom to select the best tools and build on their existing infrastructure with over 2,800 apps in Splunkbase.

We get so much value from Splunk. It maximizes the insights we gain from analyzing detection use cases, rather than wasting time creating rules or struggling with a tool that’s too complicated.

Ecosystem and Integrations

Splunk’s vibrant user community empowers innovation backed by a vast ecosystem of 2,200+ partners and 2,800+ apps on Splunkbase to extend your Splunk investment.


IBM has limited compatibility with only 600 third-party integrations for QRadar SIEM and SOAR. 


Data Optimization

Optimize your data sources for best use in the Splunk platform. Search data where it lives and only ingest into Splunk when needed for key tasks such as normalization, enrichment and data availability and retention. With Splunk Enterprise Security, you have the flexibility to store and access your data —even at the edge —and the choice to ingest key data critical to your security use cases. This ensures the most cost-effective data optimization strategy.


QRadar SIEM has limited capabilities to help you optimize your data. Because it still relies on a schema on ingestion, it is challenged by data outside the IBM ecosystem. This approach requires mapping to parse security log data properly, resulting in hidden costs for custom code development, overages to search and query logs and difficulty automating log parsing. 

Proactively Address Risk

Splunk Enterprise Security risk-based alerting (RBA) enhances prioritizations by attributing risk to users and systems, mapping alerts to cybersecurity frameworks and triggering alerts when risks exceed thresholds. This reduces alert fatigue, keeping efforts focused on detecting high-fidelity threats to proactively address risk.


QRadar SIEM lacks sophisticated risk-based alerting, and falls short on capabilities that modern SOC teams need to quickly detect, investigate and respond to threats. 


Customer Support

Splunk delivers leading-edge innovation and dedicated customer support. No other SIEM vendor can rival the commitment and loyalty exhibited by security practitioners in the Splunk global user community. 


IBM QRadar SIEM customers that have switched to Splunk Enterprise Security have reported that declining support quality was a primary reason. According to IDC, “Customer service is not always an area of focus at IBM.”


Splunk has advanced SIEM and security analytics by staying at the forefront of innovation in SecOps, helping thousands of customers outpace adversaries. Splunk unifies threat detection, investigation and response (TDIR)  workflows through integrated, industry-leading products such as Splunk Enterprise Security, Splunk SOAR, Splunk User Behavior Analytics and Splunk Attack Analyzer, addressing a broad spectrum of SecOps use cases. And we continue to rapidly innovate.

IBM QRadar’s pace of SIEM innovation has slowed, according to industry analysts.This makes it increasingly difficult for the modern SOC to solve evolving security needs. IBM has a diversified focus across hybrid cloud, data and AI, automation, security, semiconductors and quantum computing, with security being only one part of its extensive portfolio. This diffusion of focus explains why QRadar's SIEM improvements have been incremental and could increasingly become a sore spot for QRadar SIEM customers.
