📌 The Short Answer

❓ The question readers are asking: "How much does a log management solution typically cost per terabyte?"

✅ The direct answer: Between $150 and $2,500 per TB per month for ingestion, depending on the vendor.


🎯 EventGuard's answer: A low, flat rate license — not per TB, not per user, not per API call. After purchasing the license, everything else is free: no SaaS fees, no TCO, no egress charges, no per-user costs, no hidden operational expenses.

❓ Why Pricing Per Terabyte Varies So Widely

Log management pricing is notoriously confusing. Two vendors can quote wildly different per-TB rates, yet the final bill may tell a different story. Here is why:

FactorImpact on Price
Ingestion vs. storage pricingIndexed logs cost 5-10x more than cold storage
Cloud vs. self-hostedSelf-managed = lower $, higher labor
Annual commitment15-30% discount possible
Enterprise vs. startup plan2-3x price difference

⚠️ Hidden Fees That Inflate Your Bill

Most buyers only compare ingestion prices. That is a mistake. Ask about these five hidden fees:

  • Data egress – Moving logs out of cloud = extra $0.09–$0.50/GB
  • API calls – Some charge per million requests
  • Retention beyond 30 days – Can double your bill
  • Per-user fees – Enterprise plans often charge $50–$150/user/month
  • Log parsing & enrichment – Processing rules = added cost

💡 Pro tip: Request a sample invoice for your expected volume before signing.

✅ How EventGuard eliminates hidden fees: EventGuard charges a low, flat rate license. After that, everything is free: no egress fees, no per-user fees, no API call charges, no SaaS subscription costs, no TCO surprises. You pay for the license once. That's it.

✅ Where EventGuard fits: EventGuard delivers enterprise-grade log management with a low, flat rate license. Unlike SaaS vendors that charge per TB/month, EventGuard's license covers everything. After purchase: no SaaS fees, no TCO, no egress, no per-user costs, no API charges, no hidden operational expenses. What you pay for the license is all you ever pay.

🧮 How to Calculate Your True Cost Per TB

Follow these 4 steps to get an apples-to-apples comparison:

  1. Estimate daily ingestion volume – Sum all servers, containers, and apps
  2. Multiply by 30 for monthly ingestion – Example: 100 GB/day = 3 TB/month
  3. Add retention costs – 30 days is standard. 90 days = 3x storage cost
  4. Add egress + API + user fees – Get these in writing from each vendor

Real example: A mid-sized company with 500 servers generating 500 GB/day (15 TB/month):

  • Typical SaaS vendor (e.g., Datadog): $7,500–$15,000/month + hidden fees
  • Typical cloud-native (e.g., AWS CloudWatch): $5,000–$10,000/month + egress
  • EventGuard: One low flat rate license – then $0/month after that
