Kaspersky Small Office Security Base

Kaspersky Small Office Security Base protects small businesses with a server, PCs and mobile devices – easy to manage, without an IT department of your own. You install the program, sign in once, and protection then runs quietly in the background.

Why good protection matters

Small businesses are a popular target for ransomware because they rarely have their own IT department. One encrypted computer in accounts or an infected file server can bring operations to a standstill for days. A security package for small offices protects all devices consistently and can be managed without specialist knowledge.

An example from practice

A tax advisory firm with eight workstations, a file server and five company phones protects all its devices with one package. When an employee opens an infected attachment, ransomware protection stops the attack, and the management console shows immediately which computer was affected.

Everyday tips

Good software is the foundation; a few habits make protection even more effective:

• Install updates for Windows, macOS and apps promptly.
• Only open attachments if you know the sender and are expecting the message.
• Never enter passwords via links in e-mails or text messages – open the website yourself instead.
• Use a separate password for every account and enable two-factor authentication wherever possible.
• Regularly back up important files to an external drive that is not permanently connected.

System requirements

• Operating system (Windows): Windows 10 or Windows 11
• Operating system (macOS): current macOS versions
• Operating system (Android): current Android versions
• Server: Windows Server for protecting file servers
• Storage: about 1 to 3 GB of free space, depending on the platform

The manufacturer lists the exact minimum versions on its website.

Frequently asked questions about Kaspersky Small Office Security Base

When does the term start?

When the code is activated, not on the date of purchase. So you can also redeem the code later.

Does the licence renew automatically?

No. The licence simply expires at the end of the term. To renew, buy a new code when needed.

What happens at the end of the term?

The program reminds you in good time. After that, the protection features are no longer active until you enter a new code. Your settings are kept.

Can I extend existing protection?

Usually yes: enter the new code in the same account. With most editions, the remaining term is carried over.

Can I distribute the devices freely?

Yes. You can split the licence across Windows, macOS and Android as you like, as long as you do not exceed the number of devices chosen.

Can I use another antivirus program as well?

No, two antivirus programs running at the same time interfere with each other. Uninstall your old protection before installing.

Can I exchange the licence?

Yes, as long as the product key has not yet been redeemed or activated. Simply send us an e-mail.

Will I receive an invoice?

Yes, with VAT shown, with your company address on request.
