Security as a service (SECaaS) is a business model in which a service provider integrates their security services into a corporate infrastructure on a subscription basis more cost effectively than most individuals or corporations can provide on their own, when total cost of ownership is considered. SECaaS is based on the Software-as-a-Service cloud computing model, but is limited to information security type services and does not require on-premises hardware, avoiding substantial capital outlays . These security services often include authentication, anti-virus, anti-malware/spyware, intrusion detection, Penetration testing and security event management, among others. Outsourced security licensing and delivery is boasting a multibillion-dollar market. SECaaS provides users with Internet security services providing protection from online threats and attacks such as DDoS that are constantly searching for access points to compromise websites. As the demand and use of cloud computing skyrockets, users are more vulnerable to attacks due to accessing the Internet from new access points. SECaaS serves as a buffer against the most persistent online threats.
