Report Card

Executive Summary

Trellix holds a marginal position in AI-generated recommendations for endpoint detection and response software. The September 2026 LLM Authority Index benchmark shows Trellix with valid recommendation coverage of 2.50%, meaning the brand appears in a recommendation shortlist in only 13 of 520 qualified observations. Its raw mention presence rate of 5.58% indicates that AI systems name Trellix in roughly 29 observations, but the conversion from presence to recommendation is weak.

The sentiment picture is more encouraging than the coverage picture. Trellix recorded 18 positive mentions, 11 neutral mentions, and zero negative mentions in September 2026, producing a net sentiment score of 0.6207. This suggests that when AI systems do reference Trellix, the framing is generally constructive. The challenge is that these positive references rarely translate into valid recommendations.

Trellix's strongest platform signal comes from Google AI Mode, where it recorded 5 valid recommendations out of 123 observations, a coverage rate of 4.07%. This is the only platform where Trellix exceeds 4% recommendation coverage. Its weakest platform signal is Copilot, where Trellix recorded just 1 valid recommendation out of 70 observations, and ChatGPT, where it recorded 4 valid recommendations out of 71 observations but zero top-three placements.

The brand recorded a single rank-one recommendation in September 2026, appearing first in one observation on Google AI Mode. This narrow pocket of direct recommendation strength suggests that specific prompt patterns can surface Trellix as the leading answer, but those patterns are not yet repeatable at scale.

What Trellix Is Winning

Questions This Section Answers

• What is Trellix's clearest evidence-backed strength in AI recommendations?
• Where does Trellix hold its narrowest pocket of recommendation strength?

Trellix's clearest evidence-backed win is the absence of negative framing. The September 2026 benchmark recorded zero negative mentions across all 520 qualified observations. Every mention of Trellix was either positive or neutral, which is a cleaner sentiment profile than several larger competitors in the category.

The brand also holds a narrow but meaningful recommendation pocket on Google AI Mode. Trellix achieved 4.07% valid recommendation coverage on this platform, its highest platform-level rate, and recorded its only rank-one recommendation there. This suggests that Google AI Mode responses are more willing to surface Trellix as a recommended option than other AI surfaces.

Trellix's net sentiment score of 0.6207, while below the category leaders, reflects a mention base that is predominantly positive. When AI systems reference the brand, they do so constructively, which provides a foundation for future recommendation growth.

Where Trellix Has the Clearest AI Visibility Gaps

Questions This Section Answers

• How does Trellix's conversion from mentions to recommendations compare with category leaders?
• Which platforms show the weakest AI visibility for Trellix?

The dominant gap for Trellix is the conversion of presence into recommendation. The brand appears in 29 observations but is recommended in only 13, a conversion rate below 45%. By comparison, CrowdStrike Falcon appears in 468 observations and is recommended in 306, a conversion rate above 65%. Trellix is being named in AI answers without being selected as a recommended option.

Competitor displacement is severe. CrowdStrike Falcon leads the category with 58.85% valid recommendation coverage, Microsoft Defender for Endpoint follows at 56.54%, and SentinelOne holds 55.38%. Trellix's 2.50% coverage places it in the bottom tier alongside Cybereason at 2.50% and VMware Carbon Black at 2.31%. The gap between Trellix and the fourth-place brand, Sophos Intercept X at 35.38%, is more than 32 percentage points.

Trellix's top-three rate of 0.19% means the brand appears in a top-three recommendation position in only 1 of 520 observations. Its average recommended rank of 5.91, when it does receive rank-eligible recommendations, places it well outside the positions that drive buyer consideration. The brand has no presence on Gemini in the September 2026 dataset, recording zero mentions across 76 observations.

Biggest Opportunity

Questions This Section Answers

• What is Trellix's clearest path from being referenced to being recommended?

Trellix's clearest path from reference to recommendation lies in converting its existing positive mention base on Google AI Mode into repeatable top-three placements. The platform already surfaces Trellix in recommendations more often than any other AI surface, and it is the only platform where the brand has recorded a rank-one recommendation. Expanding the citation and evidence layer that supports Google AI Mode responses, while building comparable source footprints on ChatGPT and Perplexity, would give AI systems more retrievable material to justify Trellix as a recommended option rather than a passing reference.

Competitive Landscape

Questions This Section Answers

• Where does Trellix rank across top-three placement, average recommended rank, and sentiment?

CrowdStrike Falcon, Microsoft Defender for Endpoint, and SentinelOne hold dominant recommendation-stage strength in the endpoint detection and response category, with all three brands exceeding 55% valid recommendation coverage. Trellix sits in the bottom tier of the tracked competitor set, alongside Cybereason and VMware Carbon Black.

Average recommended rank covers rank-eligible recommendations only.

Trellix's position in the table reflects a brand that is present in AI answers but rarely selected as a recommended option. Its top-three rate and rank-one rate are tied for the lowest in the category alongside Cybereason, and its average recommended rank of 5.91 places it near the bottom of the field. The brand's sentiment score of 0.6207 is the second-lowest among tracked competitors, indicating that its mentions carry less positive framing than the category leaders.

Prompt Evidence

Google AI Mode / Best EDR Platform Discovery and Evaluation Prompt: "What are the software used in cyber security?" Result: Trellix received its only rank-one recommendation of the September 2026 benchmark, appearing as the first recommended option in this discovery-oriented prompt.

ChatGPT / Best EDR Platform Discovery and Evaluation Prompt: "Which tool is best for cyber security?" Result: Trellix was mentioned but did not appear in a top-three recommendation position, with the brand surfacing in lower recommendation slots or as contextual reference.

Perplexity / Best EDR Platform Discovery and Evaluation Prompt: "endpoint security software" Result: Trellix appeared in a recommendation list but at an average rank outside the top three, consistent with its overall pattern of presence without prominent placement.

What CiteWorks Studio Would Do Next

Phase 1: AI Market Discovery Audit Map the specific prompts and surfaces where Trellix appears as a reference versus a recommendation, with particular focus on Google AI Mode where the brand shows its strongest signal.

Phase 2: Recommendation Readiness Plan Identify which product attributes, use cases, and buyer segments AI systems associate with Trellix, then align owned content to those themes to improve recommendation eligibility.

Phase 3: Owned Answer Layer Buildout Develop comparison-ready content, capability documentation, and evaluation guides that give AI systems structured material to cite when assessing endpoint detection and response options.

Phase 4: Citation / Authority Layer Development Strengthen the third-party evidence base across analyst coverage, integration documentation, and customer validation to support Trellix as a recommended option rather than a passing mention.

Phase 5: Monthly AI Visibility and Recommendation Tracking Track Trellix's presence, recommendation coverage, top-three rate, and rank-one rate monthly to measure whether the conversion gap between mentions and recommendations is closing.

Why This Matters

AI-generated recommendations are becoming the first filter in enterprise technology selection. When a buyer asks an AI assistant which endpoint detection and response platform to evaluate, the brands that appear in the recommendation shortlist shape the consideration set before a single sales conversation begins. Trellix's current position means it is being named in AI answers but rarely chosen, a distinction that matters because presence alone does not influence buyer choice.

The next move for Trellix is targeted correction of the prompt, page, and citation layers that determine whether AI systems treat the brand as a reference point or a recommendation. The September 2026 benchmark shows the brand has a positive mention base and a narrow pocket of recommendation strength on Google AI Mode. Converting those signals into consistent top-three placements requires a deliberate strategy focused on the specific prompts and sources that drive recommendation behavior.

Core Metrics

Sentiment Score

Sentiment Score = (positive mentions × 1 + neutral mentions × 0 + negative mentions × -1) / total mentions

For Trellix in September 2026, this calculation is (18 × 1 + 11 × 0 + 0 × -1) / 29, producing a net sentiment score of 0.6207. This score measures the framing quality of Trellix's mentions across AI surfaces, not customer satisfaction or product performance.

Understanding this score matters because unclassified mention counts are misleading. A brand can appear frequently in AI answers while carrying negative or cautionary framing that undermines its commercial position. Share of voice is a diagnostic metric, not a business KPI. A positive recommendation, neutral reference, cautionary mention, and competitor-displaced mention are not equal signals. Counting all mentions as wins is bad measurement. Classified sentiment is required before interpreting AI visibility, because the same mention count can reflect very different market positions depending on how AI systems frame the brand.

Sentiment by Platform

Methodology

1. This report is a benchmark-based analysis of Trellix's AI market discovery position, not a client implementation case study. It is based on the LLM Authority Index AI Market Discovery Index for Endpoint Detection and Response Software.
2. The reporting window is September 2026.
3. Six canonical AI/search surface families were tracked: ChatGPT, Copilot, Gemini, Perplexity, AI Overviews, and AI Mode.
4. The benchmark began with 800 prompt-surface observations and produced 520 qualified observations after relevance and qualification filtering.
5. The competitor universe includes 10 tracked brands: Bitdefender GravityZone, CrowdStrike Falcon, Cybereason, Microsoft Defender for Endpoint, Palo Alto Cortex XDR, SentinelOne, Sophos Intercept X, Trellix, Trend Micro, and VMware Carbon Black.
6. The public benchmark measures the Brand Recommendation buyer-intent class. No qualified observations were recorded for Pricing & Value or Multi-Brand Comparison classes in September 2026.
7. Stage 0 extraction captured prompt-level observations including query, AI surface, answer, brand outcome, recommendation placement, sentiment, and citations where exposed.
8. A mention is defined as any qualified observation in which the brand appears, regardless of whether it is recommended.
9. A valid recommendation is defined as a qualified observation in which the brand appears in a recommendation shortlist with positive framing.
10. Brand-level percentages use the qualified benchmark set of 520 observations as the public denominator, not the raw 800 prompt-surface observations collected.
11. The public version of this benchmark does not include the full unique prompt count per brand. The dataset recorded 552 unique questions across 800 total prompt-surface observations.
12. Limitations: This benchmark does not measure market share, revenue, sales conversion, every possible AI response, organic-search rankings outside tested AI surfaces, social mention volume, private AI channels, or causality from metric movement alone. Source presence is evidence about the information environment, not proof that a source caused a recommendation.
