At Core4ce, our mission is clear: to protect your organization’s most critical data and IT assets. We take a proactive approach, conducting security assessments that mimic real-world cyberattacks to identify and address vulnerabilities before they can be exploited. By viewing your enterprise IT as an attacker would, we uncover potential weak points and provide you with the insights, tools, and strategies needed to fortify your defenses. Recognizing the ever-changing landscape of cybersecurity, we tailor our services to meet the complex challenges faced by today’s organizations.
Our capabilities are powered by a team of experts with decades of experience in large-scale network security. They’ve conducted hundreds of assessments for clients across government, commercial, and international sectors—ranging from complex, multi-layered networks to global corporations with thousands of live IP addresses.
They’ve worked for kings, countries, and major institutions, hacking into some of the most secure networks—with permission, of course. They remember when the offensive security industry was born – because they helped create it.
They were identified as key personnel and original members of the NSA Green Team deployed to Afghanistan on a “Find and Fix” mission. This deployment focused on identifying vulnerabilities and system owners and working with the onsite administrators to patch or reconfigure the host in a secure manner and then retest the remediation of each. The effort involved well over 60,000 systems in 100 days. The result? Multiple Red Teams were unable to gain access to the hosts upon completion of the mission.
The team’s mantra? Passwords, patches, and misconfigurations. These seemingly low-rated vulnerabilities have been exploited time and again to gain full administrative control across an enterprise—a technique our experts have perfected over the last twenty years.
What gets them up in the morning? The prospect of identifying a zero-day vulnerability – an unknown security flaw that could have devastating repercussions if left undetected. Notably, they’ve uncovered multiple zero-day exploits present in major commercial medical applications and devices.
Want to work for them? Great. Establish your bona fides and they’ll find you.
Want to work with them? Good choice. They’ll validate the defenses of your cybersecurity measures and provide a prioritized list of remediation tasks for your network and applications.
They’re Core4ce’s ethical hacking team, and they’re using their powers for good – one hack at a time.
