# Microsoft Defender vs Tech Domain

The clearest difference is review sentiment: Tech Domain at 80% against Microsoft Defender's 34%. Tech Domain also leads on in-app purchases (none vs 3) and iOS requirement (15.6 vs 17.0). Microsoft Defender's advantage is rating (4.7 vs 4.0) and ratings volume (22K vs 6). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Microsoft Defender sells 3 in-app purchases, starting at $6.99 per month. Tech Domain asks for nothing beyond the download.

Microsoft Defender holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Microsoft Defender has 22K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 34% of Microsoft Defender's written reviews are positive against 80% of Tech Domain's, so the app with the better star average is not the one people write more warmly about.

Microsoft Defender ships an update every 2 weeks, Tech Domain every 11 days. The most recent releases landed on November 8, 2026 and November 4, 2026 respectively.
