IBM QRadar Pricing 2026: EPS Tiers, On-Premise vs Cloud, and Enterprise Costs
IBM QRadar uses an events-per-second (EPS) pricing model that differs fundamentally from the per-GB approach used by Splunk and Sentinel. This guide explains EPS pricing, provides current tier costs, and calculates real-world total cost of ownership for organisations of every size.
QRadar Pricing at a Glance
QRadar's EPS pricing model charges based on the sustained average rate of security events processed by the platform, measured in events per second. This contrasts with Splunk and Sentinel's per-GB model, which charges based on raw data volume. The practical difference is significant: under EPS pricing, the number and rate of events matter more than their size. A firewall generating thousands of small connection logs per second consumes more EPS license than a database generating fewer but larger audit records.
Understanding EPS pricing requires translating your log volume into event rates. As a general rule of thumb, 1 GB of log data contains approximately 8,000-12,000 events, meaning 100 GB/day equates to roughly 800-1,200 EPS sustained average. However, this ratio varies dramatically by log source: DNS query logs may average 200 bytes per event while Windows security audit logs average 2-4 KB per event. The most accurate approach is to inventory your log sources and estimate per-source EPS rates.
The advantage of EPS pricing is cost predictability. Unlike per-GB models where enabling a verbose log source can double your bill overnight, EPS pricing changes only when you add or remove event sources. The disadvantage is less intuitive budgeting -- most organisations can estimate their daily log volume in gigabytes more easily than their sustained event rate.
EPS Tier Pricing
QRadar licensing is sold in EPS tiers. Annual maintenance (20-25% of license) covers patches, updates, and technical support. All prices are approximate and vary by region, contract terms, and negotiated discounts.
| EPS Tier | Annual License | Annual Maintenance | Approx GB/day Equiv |
|---|---|---|---|
| 100 EPS | $10,000 - $14,000 | $2,000 - $3,500 | ~12 GB/day |
| 500 EPS | $28,000 - $38,000 | $5,600 - $9,500 | ~60 GB/day |
| 1,000 EPS | $48,000 - $65,000 | $9,600 - $16,250 | ~120 GB/day |
| 2,500 EPS | $92,000 - $125,000 | $18,400 - $31,250 | ~300 GB/day |
| 5,000 EPS | $165,000 - $220,000 | $33,000 - $55,000 | ~600 GB/day |
| 10,000 EPS | $280,000 - $380,000 | $56,000 - $95,000 | ~1.2 TB/day |
QRadar's pricing structure scales sub-linearly: doubling your EPS does not double your cost. Moving from 100 EPS to 1,000 EPS represents a 10x increase in capacity but only a 4-5x increase in price. This makes QRadar increasingly competitive at higher volumes relative to per-GB models where costs scale more linearly. For very large deployments at 5,000+ EPS, QRadar's licensing can be significantly cheaper than equivalent Splunk deployments.
However, QRadar's on-premise heritage means hardware costs are a major factor. Each QRadar appliance (console, event processor, flow processor, data node) costs $25,000-$50,000 depending on specifications. A mid-market deployment at 1,000 EPS typically requires 3-4 appliance nodes ($75,000-$200,000 in hardware), while enterprise deployments at 5,000+ EPS may need 8-12 nodes ($200,000-$600,000). Hardware refresh cycles every 3-5 years add further ongoing costs. QRadar Cloud and QRadar SaaS options eliminate hardware costs but are newer products with smaller ecosystems than the established on-premise platform.
QRadar Community Edition
QRadar Community Edition provides a free, perpetual license for IBM's SIEM platform with significant limitations. The 50 EPS cap and 5,000 flows per minute limit restrict it to small lab environments, but it runs the same core engine as the commercial product. This makes it valuable for training analysts, developing custom detection rules, and evaluating QRadar before committing to a commercial license.
The Community Edition includes the QRadar console, event processor, and basic correlation engine. It supports a single host deployment (no distributed architecture), a limited number of log sources, and does not include advanced features like User Behavior Analytics (UBA), Watson AI for threat investigation, or the full QRadar App Exchange ecosystem. For production security monitoring, it is not viable for any organisation beyond a handful of servers.
As a learning tool, Community Edition is excellent. It provides hands-on experience with QRadar's offense management, rule engine, and network flow analysis. Organisations evaluating QRadar should deploy Community Edition in a lab environment for 2-4 weeks before engaging IBM sales, which gives the security team informed questions to ask and a realistic assessment of QRadar's capabilities.

QRadar On-Premise vs QRadar Cloud
QRadar's on-premise deployment has been the standard for over a decade and remains the most feature-complete option. Hardware requirements depend on your EPS tier: a 500 EPS deployment needs a minimum of a console appliance plus one event processor (2-node minimum, approximately $50,000-$100,000 in hardware). At 2,500 EPS, you need 4-6 nodes including dedicated data nodes for storage ($150,000-$300,000 in hardware). Factor in rack space, power, cooling, and a 3-5 year refresh cycle.
QRadar on Cloud (QRoC) is IBM's managed cloud offering. It eliminates hardware costs entirely and provides automatic patching and upgrades. Pricing is subscription-based, typically 30-40% higher than on-premise licensing alone, but the total cost is often lower once you remove hardware, data centre, and operational overhead. QRoC is available in IBM Cloud data centres and supports the same log sources as on-premise QRadar.
For a realistic five-year comparison at 1,000 EPS: on-premise QRadar costs approximately $600,000-$900,000 (licensing + maintenance + hardware + one refresh cycle + 1 FTE administrator). QRadar on Cloud costs approximately $500,000-$700,000 (subscription only, no hardware or dedicated admin needed). The cloud option is typically 20-30% cheaper at this scale while reducing operational complexity. For larger deployments above 5,000 EPS, on-premise can be more cost-effective due to hardware amortisation economics.
IBM QRadar Pricing FAQ
How much does IBM QRadar cost?
IBM QRadar pricing starts at approximately $10,000 per year for 100 events per second (EPS). Mid-range deployments at 1,000 EPS typically cost $48,000-$65,000 per year in licensing. Enterprise deployments at 5,000-10,000 EPS range from $165,000 to $280,000 annually. These figures cover software licensing only -- add 20-25% for annual maintenance and support, plus infrastructure costs for on-premise deployments ($25,000-$50,000 per appliance node). Total cost of ownership for a mid-market deployment is typically $200,000-$400,000 per year including staffing.
Is there a free version of QRadar?
Yes. QRadar Community Edition is a free version limited to 50 events per second and 5,000 network flows per minute. It includes the core SIEM engine with basic correlation rules, a single host deployment, and limited log source support. Community Edition is suitable for small lab environments, training, and proof-of-concept testing, but is not designed for production security monitoring. There is no time limit on the Community Edition license, making it useful for ongoing education and development work.
How do you calculate QRadar EPS requirements?
To estimate your required EPS, inventory all log sources and their average event rates. A rough guide: Windows domain controllers generate 200-500 EPS each, firewalls 100-1,000 EPS depending on traffic, web servers 50-200 EPS, database servers 20-100 EPS, and endpoint security agents 5-20 EPS each. Total your estimates and add a 30% buffer for spikes. As a very rough rule of thumb, 100 GB/day of log data equates to approximately 800-1,200 EPS depending on average event size. QRadar measures licensed EPS as a sustained average, not peak, so brief spikes above your license level are typically tolerated.
How does QRadar pricing compare to Splunk and Sentinel?
QRadar sits between Splunk and Sentinel on price for most deployment sizes. For a 50 GB/day equivalent deployment (approximately 500 EPS), QRadar licensing costs roughly $28,000-$40,000 per year versus Sentinel at $57,000-$95,000 PAYG and Splunk at $108,000-$180,000. However, QRadar's on-premise model adds significant hardware costs ($75,000-$150,000 in servers) that cloud-native Sentinel avoids. QRadar Cloud (IBM's SaaS offering) is priced more competitively with Sentinel but has a smaller feature set and less marketplace momentum.
