Insights, troubleshooting guides, and real-world solutions from enterprise Splunk environments.
A Fortune 500 client was about to spend $35,000 on new hardware. Their Splunk searches were taking 2+ minutes, dashboards were timing out, and users were complaining daily. I found the real problem in 10 minutes. It cost $0 to fix.

"Can you check why this search isn't working?" I looked at the query. Perfect syntax. Correct index. Should work. But it returned zero results. The problem? Permissions. The #1 invisible issue in enterprise Splunk.

"Why is our hot storage at 95% capacity?" I looked at their Splunk environment. 30 TB of storage across the cluster. Plenty of space.

The STIG checklist said "set minimum free disk space to 50%." So they did. And broke their entire Splunk environment. STIG compliance in Splunk isn't about following the checklist blindly.

"We're building a new Splunk environment. What's the fastest way to get it done?" Wrong question. The fastest way to build a Splunk environment is the slowest way to maintain one.

For a decade, "know what's in your software" has meant the SBOM: components, versions, licenses, vulnerabilities. AI systems broke that model, literally. The most consequential thing in an AI system is often the model, and the model is not an ordinary software component.

Most security programs watch threats against AI and software vulnerabilities as two separate disciplines, on two separate screens, owned by two separate instincts. That separation is reasonable. It is also where compound risk hides.

Your security team reports a supply chain risk score. Your board nods. Nobody asks the follow-up question: "Which vendor is driving that number?" When one vendor's components carry the highest risk score across your portfolio, that's not a vulnerability problem, it's a...

For years, federal software compliance had a comfortable shape: produce a document, sign an attestation, submit a PDF. The artifact was the proof. That era is closing, on two fronts, for two different reasons.

Every Splunk administrator has been handed the same assignment. The bill went up, nobody is quite sure why, and someone upstairs would like it to go down. What usually follows is a round of advice — filter at the edge, tune your retention, clean up your sourcetypes.

Most teams treat the license column of an SBOM as paperwork, a field the tool fills in, that nobody reads. Two things are changing that. The EU Cyber Resilience Act puts security-and-support obligations on the products you place on the market, and CISA's finalized 2026...
