DevOps ain’t easy! We are hearing more and more about the breakdown and friction where Dev meets Ops, so let’s not even talk about all the other shift-left domains that add another layer of complexity in the middle like DevSecOps. Where this comes with the need to implement and integrate dozens of security tools in their SDLC. But what if it doesn’t have to be difficult? Jit's DevSecOps Orchestration Platform allows high-velocity Engineering teams to own product security while increasing dev velocity. With a unified and friendly developer experience, we envision a world where every cloud application is born with Minimal Viable Security (MVS) embedded and iteratively improves by adding Continuous Security into CI/CD/CS.

The YAG-Suite is a French made innovative tool which brings SAST one step beyond. Based on static analysis and machine learning, YAGAAN offers customers more than a source code scanner : it offers a smart suite of tools to support application security audits as well as security and privacy by design DevSecOps processes. Beyond classic vulnerability detection, the YAG-Suite focuses the team attention on the problems that really matter in their business context, it supports developers in their understanding of the vulnerability causes and impacts. Its contextual remediation support them in fixing efficiently the problems while improving their secure coding skills. Additionally, YAG-Suite's unprecedented 'code mining' support security investigations of an unknown application with mapping all relevant code features and security mechanisms and offers querying capabilities to search for 0-days or non automatically detectable risks. PHP, Java and Python are supported. JS, C/C++ coming soon

Modern software development must match the speed of the business. But the modern AppSec tool soup lacks integration and creates complexity that slows software development life cycles. Contrast simplifies the complexity that impedes today’s development teams. Legacy AppSec employs a one-size-fits-all vulnerability detection and remediation approach that is inefficient and costly. Contrast automatically applies the best analysis and remediation technique, dramatically improving efficiencies and efficacy. Separate AppSec tools create silos that obfuscate the gathering of actionable intelligence across the application attack surface. Contrast delivers centralized observability that is critical to managing risks and capitalizing on operational efficiencies, both for security and development teams. Contrast Scan is pipeline native and delivers the speed, accuracy, and integration demanded by modern software development.

The ultimate tool to help Node.js developers secure their custom code. Developers are 4x more likely to fix issues before code is checked in. Reshift makes shifting security left seamless with security bug detection and remediation at compile time. A security tool that works with your developers, without slowing them down. Reshift integrates with the developers’ IDE so security issues are found in real-time and fixed before the code is merged. New to security? Reshift makes it easy to build code security into your pipeline for the first time. A tool built for growing software companies looking to level up their security. Not a security expert? Reshift is made for SMB’s, making it easy to set up with no need for security expertise. Improve code security, while learning about secure code.Reshift provides rich content and best practices, so developers learn about security while writing code.

The Code Registry is an AI-powered code intelligence and analysis platform that gives businesses and non-technical stakeholders full visibility into their software codebase, even if they don’t write code themselves. Upon connecting your code repository (GitHub, GitLab, Bitbucket, Azure DevOps, or uploading a zipped archive), the platform creates a secure “IP Vault” and runs a comprehensive automated analysis across your entire codebase. It produces a range of reports and dashboards, including a code-complexity score (revealing how intricate or maintainable your code is), open-source component analysis (detecting dependencies, license status, outdated or vulnerable libraries), security analysis (identifying potential vulnerabilities, insecure configurations or risky dependencies), and a “cost-to-replicate” valuation, estimating how much effort or resources it would take to rebuild or replace the software from scratch.

The Fastest Code Analysis, Hands Down. 40X faster scan times so developers never have to wait for results after submitting pull requests. The Most Accurate Results. Qwiet AI has the highest OWASP Benchmark score, which is nearly triple the commercial average and more than double the 2nd highest score. Developer-Centric Security Workflows. 96% of developers report that disconnected security and development workflows inhibit their productivity. Implementing developer-centric AppSec workflows decreases mean-time-to-remediation (MTTR), typically by 5X - enhancing both security and developer productivity. Automatically Find Business Logic Flaws in Dev. Identify vulnerabilities that are unique to your code base before they reach production. Achieve Compliance. Demonstrate and maintain compliance with security and privacy regulations such as SOC 2, PCI-DSS, GDPR, and CCPA.

Brakeman is a security scanner for Ruby on Rails applications. Unlike many web security scanners, Brakeman looks at the source code of your application. This means you do not need to set up your whole application stack to use it. Once Brakeman scans the application code, it produces a report of all security issues it has found. Brakeman requires zero setup or configuration once it is installed. Just run it. Because all Brakeman needs is source code, Brakeman can be run at any stage of development: you can generate a new application with rails new and immediately check it with Brakeman. Since Brakeman does not rely on spidering sites to determine all their pages, it can provide more complete coverage of an application. This includes pages which may not be ‘live’ yet. In theory, Brakeman can find security vulnerabilities before they become exploitable. Brakeman is specifically built for Ruby on Rails applications, so it can easily check configuration settings for best practices.

GuardRails provides a completely frictionless integration with modern Version Control Systems like Github and GitLab. GuardRails seamlessly selects the right security engines to run based on the languages in a repository. Every single rule is curated to decide whether it has a high security impact issue resulting in less noise. Has built an expert system that detects false positives that is continuously tuned to be more accurate.
