Quantum Armor

Silent Breach

Your attack surface is the sum of every attack vector that can be used to breach your perimeter defenses. In other words, it is the total quantity of information you are exposing to the outside world. Typically, the larger the attack surface, the more opportunities hackers will have to find a weak link which they can then exploit to breach your network. Professional hackers typically follow the cyber kill chain when attacking a target, and surveying the target's attack surface is normally the very first step in this process; what is known as advanced reconnaissance. Reducing the attack surface can minimize risk further down the cyber kill chain, preventing attacks before they even occur by eliminating potential attack vectors as early as possible. The cyber kill chain is a method of categorizing and tracking the various stages of a cyberattack from the early reconnaissance stages to the exfiltration of data.

Sprocket Security

Sprocket will work with your team to scope your assets and conduct initial reconnaissance. Ongoing change detection monitors and reveals shadow IT. After your first penetration test occurs, your assets are then continuously monitored and tested by expert penetration testers as new threats emerge and change occurs. Explore the routes attackers take exposing weaknesses across your security infrastructure. Work with penetration testers during your identification and remediation processes. Reveal the hackers' perspective of your organization's environment by the very same tools our experts use. Stay informed when your assets change or new threats are discovered. Remove the artificial time constraints on security tests. Attackers don't stop, and your assets and networks change throughout the year. Access unlimited retests, and on-demand attestation reports, remain compliant, and get holistic security reporting with actionable insights.

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.
