All SaaS companies should implement a cybersecurity shift left to protect their customers better. By bringing security measures closer to the development process, vulnerabilities can be identified and fixed before they become problems. This blog post will explain what a shift to the left in cybersecurity means for SaaS companies and their customers and how to get started right away!

How Does Shift-Left Testing Work, and What is it?

Shift-left testing is a software development methodology that emphasizes the importance of testing early on. Developers can catch errors and bugs sooner by shifting testing to the left, saving time and money in the long run. The order of activities in a software development cycle is "left." Testing is usually done after the coding is finished. On the other hand, shift left testing moves testing to the beginning of the cycle. This enables developers to catch errors early on and avoid potential issues later. Shift left testing can also aid in better communication between developers and testers. Involving testers earlier in the process allows them to provide valuable feedback that can help improve the final product's quality. Finally, shift left testing is a proactive approach to software development that can save time and money by catching errors early on.

What Are the Benefits of Shift-Left Testing?

Shifting left has a lot of benefits. It can assist you in reducing the overall number of vulnerabilities in your codebase. It can also lead to better communication between developers and security teams and faster detection and remediation of security issues. Consider the following advantages:

Early Detection of Defects

"Shift-left testing" refers to bringing testing earlier in the software development process to find and fix potential issues. This strategy can save time and money in the long run. Discover is a powerful shift-left testing tool that can help you catch bugs early and avoid problems later. By running automated tests against your code as you write it, Discover can help you identify potential problems quickly and fix them before they become major issues. Furthermore, Discover's visual interface makes identifying potential issues and understanding how they may affect your code a breeze.

Standardized Code Quality

The quality of code is critical to the success of any software development project. With the growing trend of shift-left testing, it is more important than ever to ensure that code is high quality and meets high-quality standards. Shift-left testing is a methodology in which testing is started earlier in the development process, typically as soon as new code is written. The goal of shift-left testing is to find and fix defects early, before they have a chance to impact the final product. By starting testing earlier, developers can avoid the costly and time-consuming process of fixing bugs later in the development cycle. One way to improve code quality is to use static analysis tools. Static analysis tools examine code without executing it, making them suitable for finding bugs early in the development process. By using static analysis tools during shift-left testing, developers can quickly identify and fix defects, improving the quality of their code.

Encourage Better Automation

As software development becomes increasingly complex, the need for effective automation tools grows more urgent. Automation can be particularly helpful in shift-left testing, which refers to moving to test earlier in the development process. By automating shift-left testing, developers can catch errors and potential problems much earlier in the cycle, saving time and effort later on. Automation can also help to improve the accuracy of shift-left testing by eliminating human error. In addition, automating shift-left testing processes can help to speed up the overall development process. When combined with other automation tools, shift-left testing automation can help developers deliver high-quality software products quickly and efficiently.

How Can SaaS Companies Get Started With a Cybersecurity Shift-Left?

It's no secret that cybersecurity is a top concern for businesses of all sizes. But for SaaS companies, the stakes are even higher. With their customers' sensitive data at risk, SaaS companies need to do everything to protect their data and ensure their customers' trust.

One way to do this is to shift security left. In other words, SaaS companies need to embed security into every stage of their development process, from design to testing to delivery. SaaS companies can catch potential security threats early and address them before they cause damage by taking this approach.

So how can SaaS companies get started with a shift left? Here are a few tips:

  1. Make security a key part of your development process. This means incorporating security into every stage of your development cycle, from design to testing to delivery.
  2. Automate as much of your security testing as possible. This will help you speed up your development process while still catching potential threats.
  3. Educate your team on the importance of security. Make sure everyone on your team understands the importance of security and knows how to spot potential threats.


Low-code test automation tools can be a lifesaver when switching to a shift-left testing strategy. They make expanding testing coverage while reducing effort easier. However, unless a dependable and resilient automation exercise exists, the shift left testing experience may not deliver the required results.
