Why is Cybersecurity important?
The digital age has made life easier and more efficient, but it has also brought significant risks to our online safety. Cybersecurity plays a crucial role in protecting sensitive data and ensuring a secure digital environment against these growing threats. Cybersecurity is essential for the following:
• It helps in protecting sensitive information like personal data, financial records, and confidential business assets from unauthorized access, ensuring data remains secure from cybercriminal threats.
• Cyberattacks can cause significant financial losses, both directly, such as through ransomware, and indirectly, like reputational damage that impacts business. In 2023, global cybercrime costs surpassed $6 trillion.
• It prevents system downtime caused by cyberattacks, helping organizations avoid business disruptions and significant financial losses
