Application security is noisy and overly complicated. The good news: you can relieve that unnecessary noise and dramatically reduce your risk of attacks with Invicti. Keeping up with security is more manageable with accurate, automated testing that scales as your needs shift and grow. That's where Invicti shines. With a leading dynamic application security testing solution (DAST), Invicti helps teams automate security tasks and save hundreds of hours each month by identifying the vulnerabilities that really matter. Combining dynamic with interactive testing (DAST + IAST) and software composition analysis (SCA), Invicti scans every corner of an app to find what other tools miss. With asset discovery, it's easier to discover all web assets — even ones that are lost, forgotten, or created by rogue departments. Through tried-and-true methods, Invicti helps DevSecOps teams get ahead of their workloads to hit critical deadlines, improve processes, and communicate more effectively.

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.

With triggers in your CI/CD pipeline, SecureStack can check for common security issues and stop those issues from getting into your applications. SecureStack embeds security automatically with every git push. We built our technology to test every facet of your application security looking for things like missing security controls, are you using encryption correctly; we test the efficacy of your WAF and are your cloud-native components secure and more than 250 other data points. All of that was delivered in less than 60 seconds. See what a hacker can see when they view your applications. Test and compare your development, staging and production environments to quickly find critical differences and understand ways to fix high-priority defects. We help you decompose your web application so you are aware of all the resources your app is using behind the scenes.

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.

JupiterOne is a cyber asset analysis platform every modern security team needs to collect and transform asset data into actionable insights to secure their attack surface. JupiterOne was created to make security as simple as asking a question and getting the right answer back, with context, to make the right decision. With JupiterOne, organizations are able to see all asset data in a single place, improve confidence in choosing their priorities and optimize the deployment of their existing security infrastructure.

OWASP ZAP (Zed Attack Proxy) is a free, open-source penetration testing tool being maintained under the umbrella of the Open Web Application Security Project (OWASP). ZAP is designed specifically for testing web applications and is both flexible and extensible. At its core, ZAP is what is known as a “man-in-the-middle proxy.” It stands between the tester’s browser and the web application so that it can intercept and inspect messages sent between browser and web application, modify the contents if needed, and then forward those packets on to the destination. It can be used as a stand-alone application, and as a daemon process. ZAP provides functionality for a range of skill levels – from developers, to testers new to security testing, to security testing specialists. ZAP has versions for each major OS and Docker, so you are not tied to a single OS. Additional functionality is freely available from a variety of add-ons in the ZAP Marketplace, accessible from within the ZAP client.
