Modern software development must be as fast as the business. The modern AppSec toolbox lacks integration, which creates complexity that slows down software development life cycles. Contrast reduces the complexity that hinders today's development teams. Legacy AppSec uses a single-size-fits all approach to vulnerability detection and remediation that is inefficient, costly, and expensive. Contrast automatically applies the most efficient analysis and remediation technique, greatly improving efficiency and effectiveness. Separate AppSec tools can create silos that hinder the collection of actionable intelligence across an application attack surface. Contrast provides centralized observability, which is crucial for managing risks and capitalizing upon operational efficiencies. This is both for security and development teams. Contrast Scan is a pipeline native product that delivers the speed, accuracy and integration required for modern software development.

Phylum defends applications at the perimeter of the open-source ecosystem and the tools used to build software. Its automated analysis engine scans third-party code as soon as it’s published into the open-source ecosystem to vet software packages, identify risks, inform users and block attacks. Think of Phylum like a firewall for open-source code. Phylum can be deployed in front of artifact repository managers, integrate directly with package managers or be deployed in CI/CD pipelines. Phylum users benefit from its powerful, automated analysis engine that reports proprietary findings instead of relying on manually curated lists. Phylum uses SAST, heuristics, machine learning and artificial intelligence to detect and report zero-day findings. Users know more risks, sooner and earlier in the development lifecycle for the strongest software supply chain defense. The Phylum policy library allows users to toggle on the blocking of critical vulnerabilities, attacks like typosquats, obfuscated code and dependency confusion, copyleft licenses, and more. Additionally, the flexibility of OPA enables customers to develop incredibly flexible and granular policies that fit their unique needs.

open-appsec is an open-source initiative that builds on machine learning to provide pre-emptive web app & API threat protection against OWASP-Top-10 and zero-day attacks. It can be deployed as add-on to Kubernetes Ingress, NGINX, Envoy and API Gateways. The open-appsec engine learns how users normally interact with your web application. It then uses this information to automatically detect requests that fall outside of normal operations, and sends those requests for further analysis to decide whether the request is malicious or not. open-appsec uses two machine learning models: 1. A supervised model that was trained offline based on millions of requests, both malicious and benign. 2. An unsupervised model that is being built in real time in the protected environment. This model uses traffic patterns specific to the environment. open-oppsec simplifies maintenance as there is no threat signature upkeep and exception handling, like common in many WAF solutions.
