Benchmark Summary

Splunk leads the SIEM Software benchmark with valid recommendation coverage of 31.9% in September 2026, down from 35.8% in July 2026. The largest coverage decline belonged to Splunk, moving from 42.0% in August 2026 to 31.9% in September 2026, a move beyond normal variation. Microsoft SharePoint recorded the largest coverage increase, reaching 0.8% in September 2026, up from 0.0% in August 2026, though the absolute counts remain small. Google Chronicle fell to 7.4% in September 2026, down from 12.0% in August 2026, also beyond normal variation.

Over the three comparable months, Splunk moved from 35.8% to 31.9%, Elastic Security held steady from 17.2% to 17.4%, and Rapid7 InsightIDR moved from 13.5% to 12.9% in valid recommendation coverage. Elastic Security, Exabeam, IBM QRadar, Microsoft SharePoint, Rapid7 InsightIDR, Securonix, and Sumo Logic all remained within normal month-to-month variation this month. Note that Microsoft Sentinel appeared in the August 2026 brand set with 35.6% valid recommendation coverage but was not tracked in the September 2026 set.

The benchmark began with 787 prompt-surface observations in July 2026, 800 in August 2026, and 793 in September 2026, producing 355, 424, and 379 qualified observations respectively after qualification.

Current Benchmark at a Glance

Measure	Jul 2026	Sep 2026	Movement
Qualified benchmark observations	355	379	Up 24
Tracked brands	9	9	No change
Qualified surface breadth	6	6	No change
Recommendation-shaped answer share	25.4%	18.5%	Down 6.9 points
Valid recommendation shortlist share	39.4%	33.8%	Down 5.6 points
Leader by valid recommendation coverage	Splunk (35.8%)	Splunk (31.9%)	Down 3.9 points

In August 2026, qualified benchmark observations rose to 424 before settling at 379 in September 2026. Qualified surface breadth counts the canonical AI/search surface families that produced at least one qualified observation. The six families are ChatGPT, Copilot, Gemini, Perplexity, AI Overviews, and AI Mode.

Research Scope and Qualification

The public benchmark is narrower than the raw collection universe by design. Brand-level percentages use the qualified observations as the public denominator, not the raw collection.

Current Brand Standings

The table below is the primary current-month benchmark view, sorted by valid recommendation coverage.

How to Read the Standings

Presence rate is the share of qualified observations in which the brand is mentioned at all. Valid recommendation coverage is the share of qualified observations in which the brand receives a clear, actionable recommendation. Top-three rate is the share of qualified observations in which the brand appears among the top three recommended options. Rank-one rate is the share of qualified observations in which the brand is the single first recommendation. Net sentiment reflects the balance of positive versus negative mentions, from -1 to +1.

Recommendation Coverage Movement

The table below tracks each brand's valid recommendation coverage from the July 2026 baseline to the September 2026 current period.

Brand	Jul 2026	Sep 2026	Movement since baseline
Elastic Security	17.2%	17.4%	Up 0.2 points
Exabeam	11.3%	7.9%	Down 3.4 points
Google Chronicle	8.2%	7.4%	Down 0.8 points
IBM QRadar	17.5%	14.5%	Down 3.0 points
Microsoft Sentinel	0.0%	0.0%	No change
Microsoft SharePoint	2.0%	0.8%	Down 1.2 points
Rapid7 InsightIDR	13.5%	12.9%	Down 0.6 points
Securonix	9.9%	9.0%	Down 0.9 points
Splunk	35.8%	31.9%	Down 3.9 points
Sumo Logic	6.2%	4.0%	Down 2.2 points

In the prior-to-current month comparison, Splunk moved from 42.0% in August 2026 to 31.9% in September 2026, a decline beyond normal variation. Google Chronicle moved from 12.0% in August 2026 to 7.4% in September 2026, also beyond normal variation.

Category Leader: Splunk

Splunk remained the coverage leader in September 2026 at 31.9%, though it declined from 42.0% in August 2026, a move beyond normal variation. Over the full baseline-to-current series, Splunk moved from 35.8% in July 2026 to 31.9% in September 2026, a decline within normal variation. Its presence rate rose to 92.6% in September 2026, up from 90.4% in July 2026. Its top-three rate fell to 24.5% in September 2026 from 30.7% in July 2026, and its rank-one rate fell to 11.3% from 13.5%.

The month was otherwise quiet for most tracked brands. Elastic Security, Exabeam, IBM QRadar, Microsoft SharePoint, Securonix, and Sumo Logic all stayed within normal month-to-month variation in valid recommendation coverage. Rapid7 InsightIDR declined slightly in each of the two months since July 2026 in valid recommendation coverage, a streak that has not yet reversed.

Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. Among the leading brands, placement patterns differed meaningfully in September 2026.

Brand	Sep 2026 top-three rate	Sep 2026 rank-one rate	Jul 2026 top-three rate	Jul 2026 rank-one rate
Splunk	24.5%	11.3%	30.7%	13.5%
Elastic Security	5.0%	0.3%	3.4%	0.0%
IBM QRadar	4.8%	0.0%	10.4%	0.0%

Close coverage figures can still hide different first-position rates. Splunk held a far higher rank-one rate than the next two brands, even as its top-three rate declined from July 2026 to September 2026.

Buyer-Intent Distribution

All qualified observations in both months fell into the Brand Recommendation class, representing discovery and consideration intent.

Buyer-intent class	Jul 2026	Sep 2026
Brand Recommendation	355	379
Pricing & Value	0	0
Multi-Brand Comparison	0	0
Total qualified observations	355	379

The current public series measures brand recommendation discovery and does not yet contain qualified observations in the pricing and value or multi-brand comparison classes.

Historical Measurement Record

This is an evergreen benchmark URL. New measurements are added to the same report.

Measurement	Qualified observations	Coverage leader	Leader coverage	Largest coverage movement
Jul 2026	355	Splunk	35.8%	N/A (baseline month)
Aug 2026	424	Splunk	42.0%	Microsoft Sentinel +35.6 points baseline to current
Sep 2026	379	Splunk	31.9%	Splunk Down 10.1 points prior to current

Evidence and Source Layer

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure market share, attributable sales, every possible AI response, organic-search ranking, social mention volume, or private and sponsored channels. A metric movement alone does not establish causality.
