Best Threat Modeling Tools with a Free Trial of 2025

Devici is a platform that helps teams move from inconsistent, document-based threat modeling to a clearer, more structured approach. It centers the work on a diagram, so AppSec and DevSecOps teams can map system behavior, add relevant attributes, and let the tool surface likely threats and recommended mitigations. This reduces the time spent interpreting static drawings or spreadsheets and gives teams a shared source of truth they can update as designs change. The workspace supports simultaneous editing, patterns for common system components, and templates that speed up modeling for recurring architectures. Security practitioners can define reusable elements, while developers can contribute without needing deep expertise in threat modeling tools. Devici also provides a maintained threat library, status tracking for each finding, and the option to integrate with issue trackers when teams need to push mitigation work into existing workflows. It offers a straightforward way to standardize threat modeling practices without introducing the overhead of heavier enterprise platforms, making it a practical option for organizations that need something accessible, collaborative, and easy to maintain.

A surge of vulnerabilities can be overwhelming, but addressing every single one isn't feasible. Utilize comprehensive threat intelligence and innovative prioritization techniques to reduce expenses, streamline processes, and ensure that your teams concentrate on the most significant threats to your organization. This approach embodies Modern Risk-Based Vulnerability Management. Our Risk-Based Vulnerability Management software is pioneering a new standard in the field. It guides your security and IT teams on which infrastructure vulnerabilities to address and when to take action. The newest iteration demonstrates that exploitability can be quantified, and effectively measuring it can aid in its reduction. Cisco Vulnerability Management (previously known as Kenna.VM) merges practical threat and exploit insights with sophisticated data analytics to identify vulnerabilities that present the greatest risk while allowing you to deprioritize lesser threats. Expect your extensive list of “critical vulnerabilities” to diminish more quickly than a wool sweater in a hot wash cycle, providing a more manageable and efficient security strategy. By adopting this modern methodology, organizations can enhance their overall security posture and respond more effectively to emerging threats.

ThreatModeler™, an enterprise threat modeling platform, is an automated solution that reduces the effort required to develop secure applications. Today's information security professionals have a pressing need to create threat models of their organizations' data and software. We do this at the scale of their IT ecosystem and with the speed of innovation. ThreatModeler™, which empowers enterprise IT organizations, allows them to map their unique security requirements and policies directly into the enterprise cyber ecosystem. This provides real-time situational awareness of their threat portfolio and risks. InfoSec executives and CISOs gain a complete understanding of their entire attack landscape, defense-in depth strategy, and compensating control, which allows them to strategically allocate resources and scale up their output.
