What are Threat Modeling Tools?
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.

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.

ARIA ADR
ARIA Cybersecurity Solutions
ARIA Advanced Detection and Response (ADR) is an automated AI SOC solution purpose-built with the capabilities of seven security tools — including SIEMs, IDS/IPSs, EDRs, Threat Intel tools, NTAs, UEBAs, and SOARs. With this single, comprehensive solution organizations will no longer have to settle for limited threat surface coverage or struggle to integrate and maintain disparate tools at substantial cost and little return. ARIA ADR’s machine learning-powered threat models, guided by AI, can find and stop the most harmful network-borne threats such as ransomware, malware, intrusions, zero-day attacks, APTs and more—in just minutes. This is a powerful advantage over most traditional security operations approaches that surface more noise than threats and require highly-trained security operations staff. There is also a cloud-based version of ARIA ADR which is a great entry level option for organizations. -

MITRE ATT&CK
MITRE ATT&CK
MITRE ATT&CK® is a globally-accessible knowledge base of adversary tactics and techniques based on real-world observations. The ATT&CK knowledge base is used as a foundation for the development of specific threat models and methodologies in the private sector, in government, and in the cybersecurity product and service community. With the creation of ATT&CK, MITRE is fulfilling its mission to solve problems for a safer world — by bringing communities together to develop more effective cybersecurity. ATT&CK is open and available to any person or organization for use at no charge. Adversaries may execute active reconnaissance scans to gather information that can be used during targeting. Active scans are those where the adversary probes victim infrastructure via network traffic, as opposed to other forms of reconnaissance that do not involve direct interaction. -

Microsoft Threat Modeling Tool
Microsoft
Threat modeling is a core element of the Microsoft Security Development Lifecycle (SDL). It’s an engineering technique you can use to help you identify threats, attacks, vulnerabilities, and countermeasures that could affect your application. You can use threat modeling to shape your application's design, meet your company's security objectives, and reduce risk. The Microsoft Threat Modeling Tool makes threat modeling easier for all developers through a standard notation for visualizing system components, data flows, and security boundaries. It also helps threat modelers identify classes of threats they should consider based on the structure of their software design. We designed the tool with non-security experts in mind, making threat modeling easier for all developers by providing clear guidance on creating and analyzing threat models. -
