Norton Safe Web review

Norton Safe Web gives Chrome users Norton's site reputation checks without a subscription. The extension queries Norton's Remote URL Reputation Service for every page you load, warns you about dangerous sites while you search, shop or browse, and automatically blocks malicious pages and downloads. Norton is clear that the free browser extensions have more limited capabilities than Safe Web inside Norton 360, where it adds AI content analysis that scans text, code and images for over 120,000 scam patterns. That makes the free version a URL filter first, which catches known bad sites well but relies on Norton's database being up to date for new ones. The Safe Web portal lets you look up any site's Norton rating and community reviews before visiting. The extension asks for several broad permissions, which Norton explains in its listing, and its Chrome Web Store rating is the lowest of the free options here. If you already pay for Norton 360, turn it on, since your plan already includes the fuller protection.
