Splunk Attack Range is a free threat simulation tool. NetSPI Detective Controls Testing is a commercial threat simulation tool by NetSPI. Compare features, ratings, integrations, and community reviews side by side to find the best threat simulation fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Detection engineers and security architects building Splunk environments need Splunk Attack Range to close the gap between rule development and real-world validation; it generates instrumented attack scenarios that let you test detections against actual adversary behavior before production deployment. The platform's 2,343 GitHub stars reflect active adoption by teams that have moved past theoretical rule tuning, and the open-source model means you're not paying licensing fees while iterating through dozens of attack chains. Skip this if your organization doesn't already have Splunk as a SIEM or lacks the engineering bandwidth to manage local lab infrastructure; Attack Range assumes technical depth and adds no value as a point-and-click simulation tool.
NetSPI Detective Controls Testing
Security teams responsible for validating whether their detection tools actually catch attacks should use NetSPI Detective Controls Testing to expose the gap between what they think they're detecting and what they're actually catching. The platform runs MITRE ATT&CK-aligned simulations across Linux, Azure, macOS, and ESXi environments, then tells you precisely which alerts fire and which don't, covering the DE.AE (Adverse Event Analysis) function that most detection stacks struggle with in practice. This works best for organizations with mature SOC operations that can act on granular detection misses; if your team is still building basic alerting rules, you'll get noise instead of insight.
An open-source platform that builds instrumented environments, simulates attacks, and integrates with Splunk for detection rule development and testing.
