BENEFITS

Fortify Your First Line of Defense

External facing systems are your first line of defense against internet-based attacks. Our pentesting provides the visibility and proactive defenses required to protect your digital perimeter from unauthorized access.

Eliminate Public-Facing Blind Spots

Gain clear visibility into your network’s open ports and public machines to proactively manage and secure your digital perimeter.

Harden Entry Points

Replicate attacks on public-facing servers, websites, and firewalls to identify weaknesses before they are exploited.

Ensure Standardized Coverage

Leverage leading OSSTMM standards to ensure comprehensive testing that identifies critical vulnerabilities across your entire external IP range.
OUR APPROACH

Targeted assessments tailored to your infrastructure

Our experts use a combination of reconnaissance, automated scanning, and manual exploitation to uncover vulnerabilities in your public-facing infrastructure:

  • Conduct passive and active reconnaissance to identify IP address ranges and public-facing assets.
  • Identify public-facing machines and resources along with their specific functions.
  • Identify weaknesses across all external endpoints and network resources.
  • Deep-dive into external attack surfaces—including web, FTP, email, and DNS servers—as well as firewalls and routers to uncover complex flaws.
  • All findings are reported and triaged in real-time via the Cobalt platform, including step-by-step remediation guidance.

Fast Start Promotion

“I haven’t had a single vulnerability back from Cobalt that isn’t a real issue. I can hand them to the engineers with confidence that they are genuine, exploitable vulnerabilities. That’s a huge time savings and a much higher value process.”
