Top 10 Cybersecurity Threats Facing SMEs in 2025

In 2025, small and medium-sized enterprises (SMEs) face a cybersecurity landscape that’s more complex and dangerous than ever before. With attackers increasingly targeting smaller businesses due to perceived vulnerabilities, it’s crucial for SMEs to understand the threats and take proactive steps to defend their operations.

Here are the top 10 cybersecurity threats SMEs must prepare for in 2025:

1. AI-Powered Cyber Attacks
