Software as a service (or SaaS) is a method for delivering applications as a service over the Internet. SaaS, also known as cloud application services, does not require software installation or maintenance and is easily accessible via the Internet. According to Gartner, SaaS is anticipated to reach $104.7 billion by 2020.

Security is vital in today’s dynamically evolving cloud environments. Here we’ve discussed the top ten DevOps security best practices. But these approaches apply to other cloud settings as well.

What Exactly Is SaaS Security?

Software-as-a-Service (SaaS) environments are especially pleasing to hackers because they contain sensitive data, including payment card numbers and personally-identifying information. As a result, businesses must emphasize SaaS security.

SaaS security refers to a collection of procedures businesses use to protect their assets when employing a SaaS architecture. According to the National Cyber Security Centre’s (NCSC) SaaS security principles, the consumer & the service provider share responsibility for security.

Vendors are now creating SaaS Security Posture Management (SSPM) systems that regulate and automate SaaS security.

Best Practices To Protect Your Application

Ensure the security of the software development life cycle

Safe SDLC entails activities that promote security at each level, so it is built into the process. This includes incorporating SaaS application security requirements alongside functionality in your project specification, analyzing architecture risks during the discovery phase, technology selection, using secure coding methodologies, performing penetration testing, and taking other precautions.

These tasks allow you to identify and address potential vulnerabilities or flaws as early as possible. For example, using the most recent versions of libraries and frameworks can automatically avoid XSS.

Compliance Certificates Must Be Rigorous

Searching for certifications such as the Payment Card Industry Data Security Standard (PCI DSS) requires a SaaS provider to go through an audit process to ensure sensitive data is transported, processed, and kept securely.

A high-security standard involves managing security, policy, procedures, software design, network architecture, and other key safeguards. SOC 2 Type II is now very useful in ensuring that the cloud service is created and operated to maintain the highest level of data security.

Safeguard Sensitive Data

It is critical to safeguard the application and database against threats such as Blind SQL injections, Authentication Failure, Security Misconfiguration, Cross-Site Scripting, XML External Entities, Broken Access Control, etc. You may also find information on the most common assaults and how to avoid them here. It is necessary to protect the data over the application using any SSL certificate like multi-domain, wildcard SSL, etc.

Make use of a CASB

In some circumstances, SaaS providers cannot deliver the level of security you require. A Cloud Access Security Broker (CASB) solution can add security measures that SaaS providers do not provide natively. CASB technologies can help supplement the security model of the provider.

When deploying a CASB tool, check that the deployment configuration (API or proxy-based) is acceptable for your organization’s architecture.


Ensuring the security of your SaaS application is paramount to protecting sensitive user data and maintaining customer trust. Adopting best practices such as regular security audits, multi-factor authentication, and data encryption is essential to protect your application from potential security breaches. By implementing these best practices and staying up-to-date on emerging security threats.
