Cybersecurity protects an organization against external and internal malicious attacks. These include denial of service attacks, phishing attempts, ransomware, malware, and spyware. Key features include continuous vulnerability scanning, threat detection, endpoint protection, application security, multilayer protection, and a capability to respond to cyberattacks. An essential capability is an ability to identify and protect against future cybersecurity threats leveraging AI and machine learning capabilities.


Cybersecurity software should include integration capabilities that allow users to blend different forms of protection such as access control, identity management, and other cybersecurity tools used in application management.


Effective cybersecurity management includes reporting capabilities that allow users to assess cybersecurity effectiveness and identify vulnerabilities and areas for improvement.
