Cybercrime is a growing concern in South Africa, with businesses of all sizes facing an increasing number of attacks. From financial fraud to ransomware, cybercriminals are targeting companies that fail to implement strong security measures. In 2025, the need for robust cybersecurity strategies has never been more critical.
