About SECaaS
If you have an email account via Gmail, Hotmail or Yahoo, then you are using SaaS (Software as a Service). Security as a Service is the security-centric application of SaaS. Many people and firms today are running antivirus systems like Malwarebytes or McAfee on their devices, which are good examples of basic Security as a Service.
The fundamental difference this makes is that security is delivered “as a service” as compared to legacy on-premise security programs. The as-a-service model, made possible by the advent of the cloud, provides you with an IT/network security platform without the need to invest in developing, managing and maintaining your own infrastructure.
Depending on your security needs and compliance requirements, there are many types of Security as a Service: threat monitoring and attack defense, data loss prevention, identity and access management, security assessment and auditing, and more.
