What is Shift Left Security? A Complete Guide
Because cyber threats grow quicker than you can say “data breach,” traditional security solutions might feel like a never-ending catch-up game. What if you could safeguard your program from the start, rather than correcting holes later? Enter Shift Left Security, a proactive strategy which includes security tests early in the development process.
Compared to traditional reactive solutions, shift left security in cyber security guarantees that vulnerabilities are identified and repaired before they become expensive. This methodology not only streamlines development but also fortifies your defenses where they matter most, right at the source. In this blog, we’ll explore what is shift left security, why it’s changing the way we think about security, and shift left security best practices that every development team should adopt.
What is shift left security?
Shift Left Security flips the traditional approach to cyber security on its head. Instead of waiting until the end of the software development process to hunt for vulnerabilities, it brings security into the conversation right from the start. Think of it as catching a leak while the pipe is being built, instead of dealing with a flood later.
Having security checks early, during coding and design, developers can spot and fix issues before they spiral into costly problems. For example, using tools that scan code for vulnerabilities as it’s being written ensures potential risks are addressed immediately. This approach isn’t just about saving time or money; it’s about building stronger, safer software from the ground up.

What is shift left testing?
Shift Left Testing focuses on moving testing earlier in the software development process. Instead of waiting until the final stages to find bugs, teams start testing during planning, design, or even as code is written. This early approach catches issues sooner, saving time and reducing the cost of fixes.
Studies show that fixing a bug during the design phase can be up to 15 times cheaper than addressing it after release. Beyond saving resources, Shift Left Testing strengthens software quality and makes the process more efficient.
This practice pairs seamlessly with shift left security, which integrates cyber security checks early on. Also, this pair can create a development cycle that’s not only faster but also more secure and reliable.

Why is Shift Left Security important?
Shift Left Security is more than just a buzzword, it’s becoming essential for businesses that want to stay ahead. The benefits are clear: tackling vulnerabilities early saves both time and money. For example, research shows that fixing a security issue during the coding phase can be up to 30 times cheaper than addressing it after deployment.
Additionally, companies that have embraced Shift Left Security in DevOps report fewer high-severity vulnerabilities, thanks to integrating security measures right into their development workflows. Catching problems before they escalate, you prevent costly fixes, reduce the risk of breaches, and make your software more secure from the start.
Adopting Shift Left Security Cyber Security practices also fosters collaboration between development, operations, and security teams, ensuring that everyone is on the same page. This proactive approach doesn’t just reduce risks, it speeds up the overall development process and improves the quality of the final product. Simply put, shifting security left is a smart investment in both your product and your peace of mind.

Key Components of Shift Left Security:
Here are the 5 main key components of shift lift security:
Security in Design:
Security in the design phase ensures that security considerations are a key part of the planning process, rather than being an afterthought. This means defining security requirements right alongside functional requirements and threat modeling at the start. Including security in the design phase can help the developers to build systems that are less likely to contain vulnerabilities or require significant changes later on.
For example, designing with secure defaults, incorporating least-privilege principles, and evaluating potential risks during system architecture design are essential to reducing attack surfaces early. This proactive approach is not only cost-effective but also strengthens the entire system’s defense.
Code Scanning and Static Analysis:
Code scanning and static analysis tools are essential to Shift Left Security because they automatically analyze source code for vulnerabilities as it is being written, long before the application is compiled or deployed. Static Application Security Testing (SAST) tools scan the code for known vulnerabilities and weaknesses in the code structure itself, without needing to run the application.
These tools help identify issues such as SQL injection vulnerabilities, cross-site scripting (XSS), and buffer overflows early in the development cycle, preventing them from being exploited later. Running automated scans during the coding phase, can help the developers to receive immediate feedback and correct issues quickly, which is one of the Shift Left Security best practices for mitigating cyber threats early.
Automated Testing:
Automated testing is a game-changer when it comes to security in development. Rather than waiting for a code review or deployment phase to spot issues, automated tests run continuously as code is being written. This means every time a developer makes a change, the system automatically checks for vulnerabilities. It helps catch things like SQL injections, cross-site scripting (XSS), and other flaws that could open the door for cyber attacks.
What makes automated testing stand out is its consistency, no developer can skip it, and it doesn’t slow down the process. Studies show that integrating these tests early on can reduce vulnerabilities in production by up to 40%, allowing developers to catch issues before they become bigger problems.
Developer Training:
It’s one thing to have tools in place, but it’s another to have developers who understand how to use them effectively. Developer training is critical in the Shift Left Security approach, making sure developers are up to speed on secure coding practices and the latest vulnerabilities.
You can make sure that security is integrated into the development process rather than being introduced as an afterthought by teaching developers to identify common security threats and how to mitigate them. Additionally, organizations with highly skilled engineers are less likely to have significant security breaches. According to studies, security awareness training can really reduce occurrences by up to 30%.
Collaboration:
Collaboration is a cornerstone of Shift Left Security. It involves breaking down silos between development, security, and operations teams to work together from the start. Instead of addressing security at the end of the development process, teams work hand-in-hand to identify and fix potential vulnerabilities early on.
This continuous communication makes security a shared responsibility, streamlining the process and ensuring faster resolutions. Research shows that organizations with strong collaboration across these teams experience 60% fewer security breaches. When development, operations, and security teams align, security becomes an integral part of the software lifecycle, reducing risks and improving overall efficiency.

How to Implement Shift Left Security?
Here’s a simple table outlining practical steps to implement Shift Left Security in your development process. This approach not only improves security but also streamlines the entire workflow, ensuring that risks are tackled early on.
| Step | What to Do | Why It’s Important |
|---|---|---|
| Start with Security in Design | Integrate security features like encryption and authentication in the design phase. Conduct threat modeling to identify risks early. | Later in the development process, risks are much decreased when security is included from the beginning. |
| Adopt Shift Left Security Best Practices | Involve security teams in the early stages of planning, design, and code reviews. Foster collaboration between development, security, and operations teams. | Security becomes everyone’s responsibility, making it easier to identify vulnerabilities earlier. |
