Compare antivirus programs for Windows
For help choosing security software, read our comparison:
It protects a device against viruses, ransomware, phishing and network attacks using Kaspersky's real-time scanning engine, which reached 100% protection with no false positives in independent AV-Test and SE Labs trials. The same engine runs across Kaspersky Free, Internet Security and the company's business tools, but here it is paired with a two-way firewall and Safe Money. In practice, when you open a banking site, Safe Money launches it in an isolated browser window and offers an on-screen keyboard so keyloggers cannot capture card details. This makes it stronger than the built-in Windows Defender for users who shop and bank online regularly.
It includes the Kaspersky VPN (Secure Connection), but the bundled version is limited to 300 MB of encrypted traffic per day. That allowance is enough to secure a short banking session or login on public Wi-Fi, but it runs out quickly during streaming, large downloads or a full working day on a hotspot. Unlimited VPN data is only available in the Kaspersky Plus and Premium plans, not in this edition. If daily private browsing matters to you, treat the included VPN as an occasional safety tool rather than an always-on connection.

For more privacy-software context, read our VPN overview:
Parental controls (Safe Kids) and the password manager are not built into this edition as full versions; they install as separate companion apps with limited functionality. The bundled password tool can store and autofill credentials but lacks the full vault, data-leak checking and unlimited capacity of the standalone Premium Password Manager. Likewise, the free Safe Kids component covers basic content filtering and screen-time limits, but advanced family management is reserved for the Kaspersky Premium plan. If a household needs proper child-safety rules per device or a complete password vault, that is a reason to look at a higher tier rather than this product.
Kaspersky replaced its classic Internet Security and Total Security lineup with three plans — Standard, Plus and Premium — that all share the same protection engine. Internet Security sits closest to the mid-range in capability: it covers core protection and Safe Money but limits the VPN and ships parental controls and the password manager only as restricted add-ons. Plus adds an unlimited VPN and the full password manager, while Premium layers on identity protection, full parental controls and priority support. The table below shows where the paid tiers differ so you can decide whether the extra privacy and family tools are worth a higher plan.
| Feature | Standard | Plus | Premium |
|---|---|---|---|
| Real-time anti-malware | ✓ | ✓ | ✓ |
| Firewall & Safe Money | ✓ | ✓ | ✓ |
| VPN | 300 MB/day | Unlimited | Unlimited |
| Password manager | ✕ | ✓ | ✓ |
| Parental controls | ✕ | ✕ | ✓ |
| Identity protection | ✕ | ✕ | ✓ |
Confirm that you do not need an always-on VPN, full parental controls or identity-theft monitoring, because those are missing or capped in this edition. The product is a strong fit if your priority is malware defense plus protected online banking on Windows or Mac, where the Safe Money browser and 100%-rated engine do the heavy lifting. Buyers comparing brands should note that Kaspersky here lacks dark-web monitoring, which Norton 360 includes at a similar level. If you mainly want clean, low-impact core protection and secure payments, this edition covers it; if you want bundled privacy and family tools, the Plus or Premium plan is the better target.
Norton and Kaspersky compared
For a direct security-suite comparison, read our article:
Yes, one license covers Windows, macOS, Android and iOS, so you can protect a mixed household from a single product. Note that protection depth varies by platform: the firewall and Safe Money are strongest on Windows, while some extras run as limited companion apps on Mac and mobile. There is no free Kaspersky antivirus for macOS, so a paid plan is required to cover a MacBook.
Kaspersky has consolidated its consumer range into Standard, Plus and Premium plans, which now use the same protection engine as Internet Security. The Internet Security edition is still available through software-key shops and remains fully functional for malware protection and secure payments. If you want unlimited VPN or full identity tools out of the box, the Plus or Premium plan is the current equivalent path.
