The Software-as-a-Service (SaaS) sector is rapidly expanding. Experts also predict that the business will be worth more than $60.36 billion by 2023. The majority of businesses have embraced or plan to use a SaaS model. SaaS can easily save costs and enhance scalability.

If you are running a SaaS business, you must know how to secure your SaaS application. Nowadays we can see so many different cyberattacks. Many SaaS businesses struggle to secure their organization and are at risk of a cyber-attack.

Why is SaaS Security Important?

  1. Cloud Service Protocols: SaaS security will assist you in complying with cloud service requirements such as ISO-27001 or GDPR. Various organizations establish these to protect sensitive information. This will help you gain customer/user confidence while also lowering the risk of a cyber attack.
  2. Shared Responsibility: SaaS security is the responsibility of both the provider and the user. As a result, the user must ensure the security of their data, operating systems, and software stacks. The SaaS provider, on the other hand, is responsible for the infrastructure, physical security, virtual machines, and so on.
  3. Access: SaaS apps are designed to be accessible from any place. This includes using public WiFi and using infected devices. You must conduct web application security testing to disclose vulnerabilities in your SaaS app.
