What are Threat Modeling Tools with a Free Trial?

Threat modeling tools are software solutions that enable organizations identify, assess, and prioritize security threats within their systems, applications, and networks. These tools enable security teams to create structured models of their infrastructure and simulate potential attack scenarios, helping to uncover vulnerabilities before they can be exploited. Threat modeling tools typically allow users to map out the flow of data, identify entry points, and analyze the potential impact of different types of threats, such as unauthorized access or data breaches. By automating aspects of the threat identification process, these tools help organizations proactively strengthen their security posture. They are essential for risk management and ensuring that security controls are effectively implemented.

DevArmor

DevArmor

DevArmor is an application security platform built for modern engineering and security teams. Instead of scanning for vulnerabilities only after code is written, DevArmor works earlier in the process — automating threat modeling and embedding secure-by-design practices directly into how teams build software. This helps organizations identify architectural and design-level risks early, where they're cheapest and easiest to fix. DevArmor is designed to fit the way engineers already work, so security becomes part of the development lifecycle rather than a bottleneck at the end. It gives security teams visibility into design risk across their applications while empowering developers to make secure decisions without needing to be security experts. With growing coverage for modern stacks — including AI-powered components — DevArmor supports AppSec, DevSecOps, and shift-left initiatives across the software development lifecycle.

Devici

Security Compass

Devici is a diagram-focused threat modeling tool that helps AppSec teams and DevSecOps engineers create clear, repeatable models without relying on scattered diagrams or manual documents. Teams map system components, describe their behavior through attributes, and Devici identifies relevant threats and possible mitigations from its maintained library. The platform supports real-time collaboration, reusable patterns, templates, and version history, which helps groups standardize how they document risks across applications. Developers can contribute without needing deep threat modeling knowledge, while security teams can guide reviews and maintain consistency. Devici offers a practical way to keep threat models current as designs change and reduces the effort required to move from architecture diagrams to actionable security decisions.

Cisco Vulnerability Management

Cisco

A tidal wave of vulnerabilities, but you can’t fix them all. Rely on extensive threat intel and patented prioritization to cut costs, save time, and keep your teams efficiently focused on reducing the biggest risks to your business. This is Modern Risk-Based Vulnerability Management. We created Risk-Based Vulnerability Management software and now we’re defining the modern model. Show your security and IT teams which infrastructure vulnerabilities they should remediate, when. Our latest version reveals exploitability can be measured, and accurately measuring exploitability can help you minimize it. Cisco Vulnerability Management (formerly Kenna.VM) combines real-world threat and exploit intelligence and advanced data science to determine which vulnerabilities pose the highest risk and which you can deprioritize. Spoiler alert: Your mega-list of “critical vulnerabilities” will shrink faster than a woolen sweater-vest in a hot cycle.
