Many of them are not noticed until weeks or months after the incident. 

Thus, a healthcare organization should invest in solid security solutions to prevent and mitigate these attacks.

You can stay one step ahead of cybercriminals and avoid HIPAA penalties by using antivirus software against malware, password managers for password encryption, a VPN for privacy, and security AI.
