Security is critical for your business

Businesses are experiencing an increase in both the volume and sophistication of cyberattacks.1 With rapid technology adoption and increased hybrid work, the risk is greater for small and medium-sized customers contending with budget constraints and gaps in specialized security skills. Microsoft offers comprehensive solutions to address this evolving threat landscape.


Increase in ransomware attacks

Ransomware is a common threat for small businesses, which make up one-half to three-quarters of the victims. Overall ransomware attacks are up almost 300% in the past year.2


Affected small businesses taken offline

Over 60% of small businesses experiencing a cyberattack were left unable to operate.3 Stay online by adopting comprehensive security with automation to rapidly detect and respond to threats.


Average cost to businesses

It’s estimated that the average cost of a data breach to a business is $108K.4 You don’t need to compromise just because you’re a small business—security that keeps you productive is a critical investment.

Comprehensive security products for your business

Modernize your business security, and upgrade from traditional antivirus software to enterprise-grade security for your apps, identity, data, and devices. Microsoft has easy to use standalone products as well as full-featured packages to keep you secure and save you time, freeing you up to focus on what matters most: running your business.
