Contrast Security
Contrast Security
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.Starting Price: $0 -

Plasmic
Plasmic
Plasmic is a visual builder for the web. Non-developers can build pages or parts of pages, and developers can integrate these into any website or app codebase.

Teams can thus move faster, iterate more, and ship higher quality products. Plasmic as a page builder and “visual CMS” is its simplest and most common use case. Editors can create and update content in Plasmic without code, and publish this into their production site without needing to block on developers. Beyond website content, Plasmic can even be used to create frontends for complex web applications (such as Plasmic itself, which was built in Plasmic). This is possible because—despite being easy to start with—Plasmic gives you full visual control and works deeply with code.Starting Price: $0 -
