Endpoint Protection
The endpoint protection category demonstrates clear market leadership with three vendors—Sophos (74%), SentinelOne (72%), and CrowdStrike (68-69%)—achieving consistently high shortlist rates across maximum model diversity (4). Microsoft 365's repeated appearance at declining rates (68%, 60%, 49%) suggests context-dependent relevance, likely reflecting its bundled security features versus standalone endpoint solutions. With 43 consensus brands but only 12 evaluation brands and zero prompt coverage, the data reveals broad market awareness but limited comparative analysis depth.
