Why Cyber Security is Important
Live Global Cyber Attack Map
According to a well-cited University of Maryland study, hackers target computers and networks almost continuously. This relentless pace highlights the non-stop vigilance needed to keep systems safe.
From small blogs to major e-commerce portals, no site is too small or too large. Cybercriminals use automated tools to scan for vulnerabilities, reminding us that proactive security is critical for every online presence.
Email remains one of the most common (and successful) entry points for hackers. Ongoing employee awareness training is vital to mitigate these risks.

The U.S. leads the world in cost per breach, underscoring just how high the stakes can be, particularly for businesses handling sensitive data at scale.
Experts estimate that cybercrime damages will surpass $10.5 trillion by 2025. This staggering number dwarfs the damage inflicted by many natural disasters and ongoing geopolitical concerns.
Attackers often remain undetected for months, giving them ample time to infiltrate networks, exfiltrate data, and cause serious damage before discovery.

Prolonged downtime means lost productivity, revenue, and customer trust. A swift, well-practiced incident response plan can make all the difference.
