Cloud Firewalls protect networks from being attacked, infiltrated, or phished for information by bad actors.  As more organizations utilize the Internet for mission critical functions it becomes ever more important to ensure that those functions remain reliable and available.  This requires both greater network redundancy and greater cloud security in order to protect the applications which are leveraging the cloud to lower costs and increase productivity.  Cloud Firewalls are key to investing this new infrastrcuture by providing reliability through multiple ISP connectivity, and additional security by employing both network-based and endpoint-based anti-virus, anti-spyware, and anti-phishing protection methods which are updated in real-time.
