Corelight logs produced up to 4x better accuracy (95.2% vs 25.8% for NetFlow), 5x greater critical incident visibility, and nearly halved investigation time (14.7 vs 27 minutes) compared to lower-fidelity sources. The research, sponsored by Corelight, concludes that data quality outweighs LLM model selection in determining SOC investigation success, and recommends security leaders prioritize telemetry quality over model upgrades. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does the quality of network telemetry data or the choice of LLM matter more for AI-driven security investigations? Data quality matters more than model selection, according to a controlled benchmark comparing Corelight enriched logs, nDPI firewall logs, Snort 3 alerts, and NetFlow across a 44-question capture-the-flag test and an incident response task. Corelight logs achieved 95.2% CTF accuracy versus 25.8% for NetFlow, a roughly fourfold difference, while using the same LLMs (Claude Opus 4.6, Gemini Pro 3.1 Preview) under identical prompts. _Teams weighing telemetry upgrades against model upgrades can track this kind of security tooling research on daily.dev._ ### How much faster is an AI security investigation when using enriched network logs instead of NetFlow data? An LLM-driven investigation completed in 14.7 minutes using Corelight enriched logs, compared to 27.0 minutes with NetFlow records and 26.3 minutes with firewall logs, nearly doubling investigation time with lower-quality data. The slowdown occurred because models entered repeated retry loops when protocol-level context was missing from the telemetry. _daily.dev is where security engineers follow findings like this when scoping SOC automation investments._ ## Similar posts on daily.dev - [Essential Data Sources for Detection Beyond the Endpoint](https://daily.dev/posts/essential-data-sources-for-detection-beyond-the-endpoint-p1jtpqr3v) · Unit 42 · 0 upvotes · 0 comments - [Why SOC efficiency is the most valuable currency in cybersecurity](https://daily.dev/posts/why-soc-efficiency-is-the-most-valuable-currency-in-cybersecurity-vges8esep) · CSO Online · 0 upvotes · 0 comments - [Addressing the 57% blind spot: Kaspersky on measuring SOC effectiveness](https://daily.dev/posts/addressing-the-57-blind-spot-kaspersky-on-measuring-soc-effectiveness-s3qgm610n) · TechCentral · 0 upvotes · 0 comments - [What an ex-NSA red teamer wants every SOC to stop doing](https://daily.dev/posts/what-an-ex-nsa-red-teamer-wants-every-soc-to-stop-doing-mmevqzeba) · The New Stack · 0 upvotes · 0 comments - [Why More Analysts Won’t Solve Your SOC’s Alert Problem](https://daily.dev/posts/why-more-analysts-won-t-solve-your-soc-s-alert-problem-qjs6yqta1) · BleepingComputer · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#llm](https://daily.dev/tags/llm) [View this post on daily.dev](https://daily.dev/posts/why-data-quality-dictates-security-operations-success-8hvktotl0) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Why data quality dictates security operations success","url":"https://daily.dev/posts/why-data-quality-dictates-security-operations-success-8hvktotl0","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/why-data-quality-dictates-security-operations-success-8hvktotl0"},"datePublished":"2026-08-17T13:59:27.345Z","dateModified":"2026-08-17T14:00:06.062Z","description":"A controlled benchmark study compared how different network telemetry sources affect AI-driven SOC investigations, testing Corelight enriched logs, open-source...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/c35a0667f445e541fadb07069654645c?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/c35a0667f445e541fadb07069654645c?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"CSO Online","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"CSO Online","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/98667e4b5cac46cf9c470819c6cf71cd","url":"https://daily.dev/sources/csoonline"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/why-data-quality-dictates-security-operations-success-8hvktotl0","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"security,llm","timeRequired":"PT6M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"CSO Online","item":"https://daily.dev/sources/csoonline"},{"@type":"ListItem","position":3,"name":"Why data quality dictates security operations success"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/why-data-quality-dictates-security-operations-success-8hvktotl0#faq","mainEntity":[{"@type":"Question","name":"Does the quality of network telemetry data or the choice of LLM matter more for AI-driven security investigations?","acceptedAnswer":{"@type":"Answer","text":"Data quality matters more than model selection, according to a controlled benchmark comparing Corelight enriched logs, nDPI firewall logs, Snort 3 alerts, and NetFlow across a 44-question capture-the-flag test and an incident response task.
