SIEM Cost and Pricing in 2026: What You'll Actually Pay

A SIEM (security information and event management) platform collects, normalizes, stores and analyzes security logs from across your environment. Teams use it to detect threats, investigate incidents and meet compliance requirements. In 2026, SIEM cost ranges from about $30,000 a year for a small organization to more than $5 million a year for a large enterprise once software, storage and staffing are included.

SIEM quotes are hard to compare, and the difficulty is built in. Vendors bill on different meters, such as gigabytes, devices, employees or data sources. Most quotes also leave out the two costs that grow fastest: storage and people. This guide puts all of it on one page so you can see the real number before you sign anything.

This guide is forsecurity leaders, IT directors, SOC managers, MSSPs and procurement teams comparing SIEM software, managed SIEM and custom-built alternatives.

How Much Does a SIEM Cost?#

The range is wide for a reason. Two companies of the same size can pay very different amounts depending on how much they log and who watches the alerts.

SIEM Cost Calculator#

We built this because nearly every pricing question we get boils down to the same five inputs: how many GB a day, how long you keep logs searchable, how many people, how many endpoints and who's watching the alerts.

Enter yours and you'll see an annual estimate for four common pricing models side by side, with and without the cost of your own analysts. The rates are list prices, either published by the vendors or reported in third-party pricing research. Negotiated deals often land 20% to 40% below list, so treat the output as a budgeting range rather than a quote.

SIEM Cost by Organization Size#

SIEM cost scales mainly with two things: how much log data you produce and whether you staff the platform yourself. Here's what that typically looks like for US organizations in 2026.

A quick guide to the columns. "Platform only" is what the vendor charges you (license or consumption plus storage), assuming you already have people to run it. "All-in" adds those people at US market pay: the low end assumes a small team working business hours; the high end assumes someone is watching 24/7. The managed SIEM column already includes the provider's analysts, which is why it looks so different.

The widest gap is in the middle. A 300-person company at 50 GB a day might spend about $58,000 a year on a per-user SIEM, or about $450,000 a year running a per-GB SIEM with two in-house analysts. (You can reproduce both numbers with the calculator above.) Same company. Same logs. An eightfold difference. Most of the time, the pricing model and the staffing decision move your bill far more than which vendor's logo is on the dashboard.

SIEM Pricing Models Explained#

SIEM vendors use seven main pricing models: per-GB ingestion, GB/day capacity, events per second, per asset, per user, per data source and flat subscription tiers. Managed SIEM providers usually wrap one of these in a monthly service fee.

The question to ask of each one is simple: what makes the bill go up? With per-GB it's your logs. With per-asset it's your devices. With per-user it's your headcount. Pick the meter that grows slowest in your business.

Per-GB Ingestion: The Default, and the One That Bites

Per-GB pricing charges you for every gigabyte of logs the SIEM takes in, a bit like paying for electricity by the kilowatt-hour. It's the most common model, and it's behind most of the surprise invoices we see.

The published rates look reasonable on their own:

• Microsoft Sentinel costs about $4.30 per GB pay-as-you-go in East US. Commit to 100 GB/day and the effective rate drops to about $2.96 per GB; Microsoft says commitment tiers save up to 52%.
• Elastic Security Serverless publishes rates from $0.09 to $0.11 per GB ingested, plus $0.017 to $0.019 per GB per month for what you keep.
• CrowdStrike Falcon Next-Gen SIEM runs about $5.95 per GB pay-as-you-go on AWS Marketplace. If you already run Falcon Insight XDR, you get 10 GB/day of third-party data free.

The trouble is that log volume doesn't grow politely. Turn on a new firewall, move a workload to the cloud or have one bad week with an incident, and ingestion can jump overnight. Your budget, set 12 months earlier, doesn't move with it.

Events per Second (EPS)

EPS licenses throughput instead of volume. It works fine in stable environments. But during an incident, a flood of alerts from noisy sources can push you past your licensed rate at exactly the moment you can least afford a throttled SIEM. That's a hard thing to size for in advance.

Per-Asset and Per-User Pricing

Asset pricing charges a flat rate per monitored device, so the bill follows your infrastructure rather than your logs. Rapid7 InsightIDR lists at about $5.89 per asset per month, with a 500-asset minimum.

User pricing charges per employee and usually includes unlimited data. Published plans run $12, $16 and $21 per employee per month. For a small company with chatty firewalls and a modest headcount, this is often the most predictable bill you can get.

Managed and As-a-Service Pricing

Managed SIEM bundles the platform with people who monitor, tune and respond. Some providers sell it as "SOC as a service." "SIEM as a service" usually means hosting only, which we compare below. Providers usually price it per endpoint, per user or per data source each month, or as a flat retainer. Full rates are in the Managed SIEM Pricing section.

SIEM Pricing Comparison: 2026 Vendor Prices#

Published SIEM pricing ranges from about $0.10 per GB (Elastic) to about $6 per GB (CrowdStrike pay-as-you-go), while Splunk, Google SecOps and Exabeam sell mainly on quotes.

One caution about this table: pricing transparency varies a lot. Where a price isn't marked vendor-published, it comes from deal data or third-party research. Use it to sanity-check a quote, not to replace one. Prices were checked in October 2026.

Open-Source vs. Commercial SIEM Pricing

Open-source SIEMs such as Wazuh and OpenSearch have no license fee, but you pay for infrastructure and the engineers who run them. Commercial SIEMs charge for the license and ship with more vendor-maintained detection content. Which one ends up cheaper depends almost entirely on whether you have the people. For a related comparison, see our guide to open-source vs. custom-built SIEM.

What Drives SIEM Cost?#

SIEM cost is driven by four things: how much data you ingest, how long you keep it searchable, which feature tier you need and how many tenants or business units you run.

1. Log Ingestion Volume

On per-GB platforms, ingestion is usually the biggest line on the bill. And the irony is that the noisiest sources (firewall, DNS, proxy, NetFlow, verbose Windows events) tend to produce the fewest useful detections. You end up paying premium rates to store data you rarely query.

2. Storage and Retention Policies

Storage and retention policies raise long-term SIEM cost because stored data compounds: every month you pay to keep new logs while still paying for old ones.

It's the cost people underestimate most, because it creeps. In month 1 you pay to store one month of logs. By month 12 you're paying for 12 months of logs. Keeping a full year searchable can cost several times more than keeping 90 days searchable and archiving the rest, and nobody notices until the second-year invoice. In the US, a few rules usually set the minimum:

• PCI DSS (Requirement 10.5.1): at least 12 months of audit logs, with the latest three months immediately available.
• OMB M-21-31 (federal agencies and contractors): 12 months in active storage plus 18 months in cold storage.
• HIPAA, SOX and state laws add their own expectations, so check with your compliance team before you size retention.

Vendors handle this very differently, which is why two quotes for "the same" SIEM can be far apart. Google SecOps includes 12 months of hot retention in its ingestion price. Some per-employee SIEMs include 365 days. Microsoft Sentinel keeps 90 days in its analytics tier and sells a separate, much cheaper data lake tier for the long tail.

3. Feature Tiers

UEBA, threat intelligence, SOAR automation and AI assistants tend to live in higher tiers or come as add-ons. It's tempting to sign for the entry tier and upgrade later. Don't, unless you're sure. Price the tier you'll need in year two, because asking for an upgrade mid-contract is about the weakest negotiating position there is.

4. Tenant Count and Deployment Model

If you run several business units, or you're an MSSP with dozens of clients, per-workspace or per-instance pricing multiplies fast. Cloud SIEM gets rid of hardware but adds metered storage, query and egress fees. On-premises SIEM moves those costs to servers and the people who keep them running. Our multi-tenant SIEM architecture guide goes deeper on how tenancy changes the math.

SIEM Total Cost of Ownership (TCO)#

SIEM total cost of ownership is the license plus storage, deployment, integrations, detection tuning and the people who run it, measured over the contract term, usually three years. For a self-run SIEM, the license is often less than half of that.

If you want it as a formula:

The first term is the one on the quote. Everything after the first plus sign is where budgets go wrong.

The Cost of Security Staff

People are the most expensive part of a SIEM, and it isn't close. In one published three-year comparison for a 200-employee organization, staffing made up roughly 61% to 72% of total cost for enterprise and cloud SIEMs.

Here's why 24/7 coverage gets expensive so quickly. We worked this out from government pay data:

1. 8,760 hA year has 8,760 hours. A full-time analyst works roughly 1,800 productive hours once you take out leave and training.
2. × 5So keeping one seat staffed around the clock takes about five analysts.
3. $185KThe median US information security analyst earned $129,180 in May 2025 (BLS). Wages are about 70% of what employers actually pay per worker once benefits are counted (BLS, June 2026), which puts each analyst at about $185,000 fully loaded.
4. $920KFive analysts cost roughly $920,000 a year. And that's before a SIEM engineer, a manager or the software.

So when a team tells us they plan to run their SIEM in-house, 24/7, with two people, this is the math we walk through. Two people can cover business hours well. They can't cover nights, weekends, holidays and sick days too. It's also why managed SIEM exists.

Deployment Cost and the Hidden Extras

These ranges come from a published 2026 SIEM TCO analysis, which also found that first-year SIEM costs commonly run 40% to 60% over the original estimate. In our experience, integrations are the usual culprit: every in-house app and legacy system needs a parser, and nobody counted them during procurement.

Managed SIEM Pricing#

Managed SIEM pricing typically ranges from $3,000 to $15,000 per month for small and mid-size businesses and $15,000 to $50,000+ per month for enterprises, depending on endpoints, log volume and analyst coverage.

Think of it as renting the platform and the night shift together. You pay for the SIEM, the people watching it and some level of response, and in exchange most of the staffing problem from the last section goes away. For a lot of small and mid-size teams, that trade is worth it.

How Managed SIEM Vendors Price the Service

What's Usually Included, and What Usually Isn't

This is where managed SIEM quotes stop being comparable. Two providers can quote the same monthly price and deliver very different things, and you usually find out which one you bought during your first real incident.

Get the exclusions in writing before you compare anything.

Managed SIEM vs. MDR vs. SIEM as a Service

These three get used interchangeably, but they aren't the same thing:

• Managed SIEM: a provider runs a SIEM (theirs or sometimes yours) and monitors it for you.
• MDR (managed detection and response): response comes first. It usually runs on the provider's own endpoint or XDR tooling and cares less about long-term log retention.
• SIEM as a service: a cloud-hosted SIEM platform. Some vendors include monitoring; many just host the software.

How to Calculate Managed SIEM Cost for Budgeting#

To budget for managed SIEM, count your endpoints, users and daily log volume, choose the coverage level you need, then multiply by each provider's pricing unit and add exclusions and growth. In practice, it goes like this:

1. 1Count your billing units. Endpoints, servers, cloud workloads, employees and log sources. Measure your average and peak daily log volume in GB; the peak matters more than you'd think.
2. 2Decide on coverage. Business-hours coverage (8x5) is much cheaper than 24/7, but most regulated organizations can't get away with it.
3. 3Set retention to the longest requirement you face. For anyone handling card data, that's 12 months under PCI DSS.
4. 4Apply each provider's unit price. For example: 400 endpoints × $25 = $10,000 a month. Or 60 GB/day × $1.50 × 30 days = $2,700 a month.
5. 5Add the exclusions: extra retention, custom detections, incident response hours, onboarding.
6. 6Stress-test for growth. Re-run everything at +30% and +50% volume. Some pricing models hold up; others fall apart.

How to Compare Pricing Models for Managed SIEM Vendors#

Compare managed SIEM vendors on total three-year cost at your expected growth, not on the headline unit price. Give every provider the same inputs, then ask each of them these questions:

If a provider hesitates on the last two, take note.

In-House vs. Managed vs. Custom-Built SIEM: Cost-Benefit Analysis#

A managed SIEM is usually cheapest for small teams, a licensed SIEM run in-house suits mid-size teams with security staff, and a custom-built SIEM becomes cost-effective at high log volumes or for MSSPs with many tenants.

Full disclosure: building custom SIEM platforms is what we do, so weigh our opinion accordingly. For most small teams, a custom build is the wrong answer, and we'll tell you that on the first call. Where it does make sense is at scale. In one of our published case studies, an MSSP that moved off per-GB SIEM pricing to a platform it owned saved $270,000 over 24 months. Our custom SIEM development page lists our build price bands if you want to compare.

How to Reduce SIEM Complexity and Costs#

The most reliable way to reduce SIEM cost is to send less low-value data to the expensive analytics tier, not to collect less data. Cutting what you collect saves money but leaves blind spots, and you'll only discover them when an investigation needs the logs you dropped. Moving what you collect to cheaper storage saves money and keeps the evidence. The same steps cut complexity too: fewer overlapping tools, fewer parsers to maintain and fewer noisy alerts to triage.

These are the cost optimizations we'd try first, roughly in order:

1. 1Filter and route data in a pipeline. A security data pipeline strips duplicate fields and noisy events before they hit the SIEM, and sends the raw copy to cheap storage. Events DC cut SIEM ingestion by 30–35% this way, and a US retailer brought its Splunk license down from 1 TB/day to 750 GB/day (both are vendor-published case studies, so treat them as examples).
2. 2Tier your data. Identity, endpoint and alert data belongs in the analytics tier. Firewall, proxy and flow logs can usually live in a data lake tier at a fraction of the price.
3. 3Right-size your commitments. Once daily volume is stable, a commitment tier is the easiest saving available. Sentinel's commitment tiers save up to 52% over pay-as-you-go.
4. 4Match retention to the actual requirement. Keep the searchable window as short as your regulations and investigations allow. Archive the rest.
5. 5Check detections against sources. If no detection rule or investigation ever touches a log source, ask why it's in the SIEM at all.
6. 6Consolidate tools. Running two or three overlapping SIEM, log and XDR tools means paying twice for licenses and twice for the people who manage them.
7. 7Negotiate properly. Ask for multi-year rate locks, a cap on renewal increases and written overage terms. Third-party pricing research suggests 20% to 40% off list is common on negotiated deals.

Security Data Lake vs. Traditional SIEM Cost

At high volumes, a security data lake with detections running on top can cost a lot less than a traditional SIEM that keeps everything in hot storage. The catch is that it takes more engineering to run. The savings are only real if you have, or can hire, the people to operate it.

Low-Cost SIEM Solutions: What You Get at Each Price#

Low-cost SIEM options include Wazuh Cloud from about $571 a month, Elastic Security from about $0.10 per GB ingested, per-employee SIEMs from $12 per employee a month and CrowdStrike's 10 GB/day free tier for its endpoint customers.

• Free or open-source (Wazuh, OpenSearch): no license at all, but you need engineers to deploy, tune and maintain it.
• Low per-GB rates (Elastic Serverless): the cheapest published per-GB pricing, with more of the detection engineering left to you.
• Per-employee SIEM: predictable and often the most cost-effective option for SMBs with heavy log volume.
• Managed SIEM for small businesses: a low entry price with SOC monitoring included.

The most cost-effective SIEM isn't the one with the lowest license fee. It's the one with the lowest three-year total for the coverage you actually need. A free SIEM that needs two extra hires to run is, in practice, a $370,000-a-year SIEM.

For MSSPs: Pricing Managed SIEM to Your Clients#

If you run an MSSP, you're on both sides of this problem. You pay your SIEM vendor per GB, and you charge your clients per endpoint or per user.

That mismatch is where margin quietly disappears. Your vendor bill grows with each client's log volume, but what you charge them stays flat per endpoint. One noisy client (a chatty firewall, a misconfigured app, a busy month) can wipe out the margin on that account without anyone noticing until the invoice arrives.

What helps: per-tenant ingestion limits, data tiering and client pricing tiers that account for log volume, not just endpoint count. Our guide to MSSP infrastructure optimization walks through each of these in practice. The structural fix is owning the platform, so a new client adds infrastructure cost rather than a per-GB license. That's the model behind our MSSP engineering partner service.
