Rankiteo Explanation : Attack with significant impact with customers data leaksDescription: Yale New Haven Hospital (YNHH) suffered a data breach incident after a file created for research was unintentionally posted on a public facing website and was accessed by a small number of people. The exposed file included name, telephone number, email address, age range, preferred language, medical record number, procedure type, and date and location of service. YNHH engaged a third-party forensic firm to assist us in our investigation and ensured the website and content were no longer accessible or searchable via the internet. | |||||||

What Do We Measure?
Every week, Rankiteo analyzes billions of signals to give organizations a sharper, faster view of emerging risks. With deeper, more actionable intelligence at their fingertips, security teams can outpace threat actors, respond instantly to Zero-Day attacks, and dramatically shrink their risk exposure window.
These are some of the factors we use to calculate the overall score:
Identify exposed access points, detect misconfigured SSL certificates, and uncover vulnerabilities across the network infrastructure.
Gain visibility into the software components used within an organization to detect vulnerabilities, manage risk, and ensure supply chain security.
Monitor and manage all IT assets and their configurations to ensure accurate, real-time visibility across the company's technology environment.
Leverage real-time insights on active threats, malware campaigns, and emerging vulnerabilities to proactively defend against evolving cyberattacks.
