Best 11 IaC Tools For 2025

Code your way to optimal cloud security. Infrastructure as Code (IaC) tools like Terraform, AWS CloudFormation, and Azure Resource Manager empower you to manage and secure your cloud infrastructure with code, ensuring consistency, compliance, and reduced risk across your entire cloud estate.

Traditional methods of infrastructure development are tedious and time-consuming. Organizations are always looking for efficient ways to build and deploy scalable applications without compromising agility or flexibility. An Infrastructure-as-a-Code development tool (IaC) gives companies all the features and resources they need to manage IT resources and consistently automate their provisioning.

Infrastructure as Code solutions can transform enterprise outcomes by enhancing efficiency and providing ease of use, flexibility, and versatility during the development of projects. Below, we will describe what IaC security tools are and which are the best IaC Tools in 2025 that can fit your different project requirements.

What are IaC Tools?

IaC tools are special software solutions that provide a method of provisioning and managing IT resources using machine-readable files or code. IaC tools help organizations cut expenses, enhance speed, and reduce risks brought about by manual configurations.

In DevOps environments, increasing automation and promoting standardization is critical to success. Organizations need to build, deploy, and reduce time to market web infrastructure applications and easily accommodate changing resource demands. Modern IaC tools support advanced scalability and seamless updates, preventing sudden downtimes or disruptions.

Need for IaC Tools

More and more businesses are relying on Infrastructure as Code (IaC) to automate and scale IT operations. IaC lets organizations define, manage, and provision infrastructure quickly and uniformly through code. However, with this level of automation comes one significant risk: codifying security vulnerabilities that can rapidly spread throughout an entire infrastructure.

The Capital One Data Breach taught us many lessons in the past. This incident was not solely IaC-related but was initiated by a firewall misconfigured within their cloud setup, providing access to confidential customer data from over 100 million users. This event shows that such configuration mishaps are catastrophic. We need o to take them seriously. When such misconfigurations are included within IaC templates, they are copied into every deployment and increase the radius of damages. 

Cybercriminals are well aware of these weaknesses. They’re now focusing more on code weaknesses in the infrastructure, knowing that if they crack one, they would get to an organization’s sensitive assets. Most traditional security mechanisms are geared toward applications and networks and pay little attention to the code that defines infrastructure. This leaves blind spots for weaknesses to hide, waiting until they are found out.

IaC tools are built to scan, analyze, and report infrastructure code for misconfigurations, compliance violations, and security weaknesses before they are introduced into production environments. They fix vulnerabilities before adversaries can reach and exploit them. 

For CISOs and CEOs, the stakes go beyond immediate financial losses. IaC’s weaknesses include regulatory penalties and tarnishing brand images. Security engineers and SOC analysts must protect dynamic, code-driven environments where traditional security tools often fail. IaC security tools provide visibility and control over the code that constructs the infrastructure to arm security teams with the means to protect their organizations effectively.

Overlooking IaC security is like laying a foundation riddled with cracks; it’s only a matter of time before the structure falters. IaC’s automated nature means that any embedded vulnerability isn’t just a single point of failure but a flaw that goes through the entire system. Infrastructure as Code security isn’t optional anymore. We need it, and that’s why the demand for IaC tools will continue to surge.
