The Ingestion Tax: Why Your SIEM Budget Is Broken
I have spent my career scaling B2B companies, and I have seen plenty of broken pricing models. But I have never seen anything quite as backwards as the way legacy SIEMs charge for security.
The core of the problem is the Ingestion Tax: you pay per gigabyte of data your SIEM ingests. Not per threat detected. Not per incident resolved. You are being billed based on how much data your business generates, essentially a tax on your own growth.
The Math of Failure
In 2026, the average cost across major SIEM vendors sits at about $0.88 per GB. Let us look at what a mid-size organization actually pays to stay "visible":
- Ingestion (500GB/day): $160,600/year
- Infrastructure and Compute: $200,000/year
- SIEM Add-ons/Integrations: $75,000/year
- Dedicated SIEM Admin Salary: $150,000+
Year 1 Total: $585,600+
Here is the question that keeps me up at night: How many threats did that $585K stop? Ingestion does not stop threats. Indexing does not stop threats. These are infrastructure costs disguised as security spending.
The Growth Penalty and The AI Explosion
The most insidious part of per-GB pricing is how it reacts to the modern "AI Storm." As attackers use AI to automate campaigns, security teams are forced to investigate lower-level "informational" alerts.
To catch a silent AI attacker, your investigative depth might need to increase 5x to 50x. Under a legacy SIEM model, your bill does not just grow. It goes vertical. I have talked to CISOs who deliberately dropped log sources to keep costs under control. They made their organization less secure because the tool designed to protect them was too expensive to "feed."
The Healthcare Case Study: Visibility Without the Tax
A regional healthcare system recently faced a $1.8M annual SIEM renewal. With 14 hospitals and thousands of medical devices, dropping data was not an option. It was a compliance risk.
By deploying Vigilense AI with BYODb, they retired the legacy SIEM entirely. They kept their telemetry in their own Snowflake and S3 buckets.
- Result: $2.1M in first-year savings.
- ROI: 340%.
- Visibility: 100% of log sources maintained.
Legacy Pricing for a World That No Longer Exists
Per-GB pricing made sense 15 years ago when data was scarce. Today, your data is already in modern platforms like BigQuery or Snowflake. Paying a SIEM vendor to re-ingest and re-index data you already own is paying twice for the same thing.
In 2026, data centralization is table stakes. Intelligence is the hard part.
Choose Your Future
Next time your SIEM renewal lands on your desk, ask one question: What percentage of this cost is actually stopping threats? If most of it is going toward the "Ingestion Tax," you are not buying security. You are buying a storage bill.
There is a better way. Stop paying the tax. Start catching the threat.
