What is Pricing model?

Pricing model describes the shape of a provider's charging rather than the amount: a free tier, a low-cost entry plan, or a paid-only product. 2FAS and Adaware Antivirus both pair free with a budget plan, so a reader can try the product before paying. 360 Total Security (Qihoo 360) sits on free alone, and Acronis and Acronis Cyber Protect are budget entries. The trade-off a reader weighs is flexibility against upkeep: a free tier removes the buying decision but often narrows the feature set, while a paid plan costs more and needs a renewal. Check the billing period on any paid tier before you commit.
