ESET vs Microsoft Defender

ESET and Microsoft Defender compared side by side: protection, performance, pricing, and features. Which antivirus suits you better?

ESET

/ 10

ESET Home Security Essential is the top choice for users seeking a lean, high-performance security solution. The software barely taxes the system, making it excellent for gamers, freelancers, and older hardware. Protection levels are very high, even though the feature set is slimmer than Norton or Bitdefender. In return, renewal costs are more moderate than many competitors.

Microsoft Defender

8.7

/ 10

Microsoft Defender comes pre-installed on every Windows PC and provides solid baseline protection against malware, phishing, and ransomware. In independent tests, Defender now performs well and is often sufficient for users with cautious browsing habits. However, anyone who needs VPN, password manager, extended web protection, or parental controls should consider a paid suite. As a free reference point, Defender is the most important comparison benchmark.

Our verdict

Microsoft Defender is a respectable free baseline for Windows in 2026. ESET (score: 8.8 out of 10) adds web/phishing filter, ransomware module, VPN and password manager – features Defender still does not provide.

On price, ESET currently sits at CHF 38 in year one, Microsoft Defender at CHF 0. Watch the renewal price closely: both are transparently listed in the table above and matter more long-term than the introductory price.

Strength profiles: ESET scores highest on system impact, Microsoft Defender on price-performance. If you care most about one of those dimensions, the choice is clear. For all-round needs, either product is a safe pick.
