Small Business Cybersecurity: Your Complete Protection Strategy

Small businesses face increasingly sophisticated cyber threats, with 43% of cyberattacks targeting small and medium enterprises. Unlike consumer antivirus solutions, businesses need enterprise-grade protection that can scale, provide centralized management, and protect against advanced threats that target business data and operations.

Why Small Businesses Need Professional Antivirus

The Small Business Threat Landscape

Small businesses are prime targets for cybercriminals because they often have valuable data but limited cybersecurity resources. With the rise of remote work, 32% of organizations are concerned about malware, while 24% worry about sensitive data on remote devices.

  • Ransomware attacks can cripple business operations for weeks
  • Data breaches can result in significant financial losses and reputation damage
  • Compliance requirements demand robust security measures
  • Remote work expands the attack surface exponentially

Critical Business Risks

Consumer antivirus solutions lack the centralized management, advanced threat detection, and business-specific features needed to protect company data, manage multiple devices, and ensure compliance with industry regulations.
