Valuable Features

Contrast Security Assess is praised for integration, real-time detection, accuracy, and collaboration, enhancing security with IAST and CI/CD support.
Nucleus Security enhances safety and efficiency by streamlining risk management, integrating tools, and prioritizing risks for faster remediation.
The real-time detection feature of Contrast Security Assess helps us very well compared to traditional SAST tools. Traditional tools scan from the outside and guess where problems might be. Contrast Security Assess works from the inside because it is embedded into the application.
Dev Ops Engineer at a tech vendor with 1,001-5,000 employees
The ability to see what is going on and what has been going on in a given application and basically get to see what is coming across it in real time is helpful in finding vulnerabilities to remediate before production deployments.
Threat & Vulnerability Management Senior Analyst at a tech vendor with 10,001+ employees
Instead of fixing each vulnerability reported independently, you can group them and fix them in a single point in the source code, resolving several vulnerabilities at once.

By centralizing everything, Nucleus Security has completely eliminated that friction and dramatically cut down on alert fatigue across our infrastructure and support teams because the platform prioritizes risk based on real-world threat intelligence.
Manager at a computer software company with 201-500 employees
The risk-based prioritization has helped my team focus on the most critical vulnerabilities by considering severity, asset context, and the remediation priorities.

Featured Reviews

Dev Ops Engineer at a tech vendor with 1,001-5,000 employees
Continuous in-app security has transformed our development workflow and has reduced manual checks
Contrast Security Assess changes how the team thinks about security. Instead of us waiting for a security audit at the end of any sprint, vulnerabilities surface as developers are writing and testing code. That shift is significant because fixing a bug in development costs more than fixing it later. It captures everything right there and remediates it because it catches vulnerability and remediates immediately while the application is running. It improves our collaboration between development and security teams, as developers get clear actionable findings immediately. We get continuous visibility into our application risk posture. Ultimately, it helps us to shift fast and save money, which is usually a trade-off, but Contrast Security Assess makes both possible. The feature that stands out most to me in Contrast Security Assess is the ability to capture vulnerability while the application is running. Another standout feature is the real-time detection that finds vulnerabilities as code runs. It has fewer false positives and works continuously in the application; you install it and it is there. It captures issues during development quickly and is easily integrated with a CI/CD pipeline, especially if you are using GitLab or GitHub. The real-time detection feature of Contrast Security Assess helps us very well compared to traditional SAST tools. Traditional tools scan from the outside and guess where problems might be. Contrast Security Assess works from the inside because it is embedded into the application. The agent lives inside the running application, allowing it to see exactly what is happening in real-time. This means we are getting accurate alerts instead of a long list of potential issues that require manual investigation. When it comes to the CI/CD pipeline, Contrast Security Assess really shines for our daily work, as it plugs directly into tools like Jenkins, GitHub, or Azure DevOps. When a developer commits code and triggers a build, Contrast Security Assess is already testing it in the background. If there is any vulnerability, the pipeline automatically flags or stops the application before bad code reaches production. This means security becomes everyone's responsibility, not just the security team's, and it gives us real-time, accurate security that fits into how our team already works.

Unified vulnerability view has improved risk-based decisions but reporting still needs work
One of the main issues with Nucleus Security is its lack of reporting capability. The user interface resembles an early 2000s application style, and although its speed is decent, it could be improved as more data is ingested. The overall appearance and feel need work, especially compared to modern applications from Rapid7, Qualys, and Tenable, which have more engaging user interfaces. The reporting capability is severely lacking; not being able to filter to granularity or have custom built queries is an annoyance that needs an overhaul. Additionally, there are bugs that have not been resolved, such as when you create a report and remove an asset, the asset still appears in the report despite not being present in the system anymore, leading to issues that need to be addressed quickly. Nucleus Security can become a difficult investment because I already have a vulnerability management solution, and I question where Nucleus Security fits with its licensing model. While I acknowledge automation has been described, it would be amazing to control the entire vulnerability management workflow from Nucleus Security without needing to log onto other systems. Having controls or actions that can be sent from the console down to the scanner for rescans would be beneficial. If Nucleus Security is going down this path, it should ensure that it becomes a one-stop shop for vulnerability management across multiple applications.
