Entergy Company Cyber Security Posture
entergy.comAt Entergy (NYSE: ETR), we power life. More than 100 years ago, our founder Harvey Couch started this company with a handshake, some sawdust and a vision. Couch wanted to bring safe, affordable, reliable energy to the Middle South โ energy that would power the lives of people and communities. Today, we own and operate one of the cleanest large-scale U.S. power generating fleets including more than five gigawatts of carbon-free nuclear capacity, a fleet of highly efficient gas resources, and a fast-growing portfolio of renewable resources. The nearly 12,000 men and women of Entergy deliver electricity and gas services to 3 million utility customers in Arkansas, Louisiana, Mississippi and Texas, generating annual GAAP revenues of $13.8 billion. Headquartered in New Orleans, we continue to play a driving role in the economic growth of the Gulf South. Our work matters. Thatโs been true for more than 100 years. And as we look to the next century, we remember the constant that bridges our past and future: We Power Life. Fast Facts: Entergy currently has a 90% rating on the 2022 Corporate Equality Index released by the Human Rights Campaign Foundation. This score places Entergy among the top energy and utility companies in the survey. With roots in the Gulf South region for more than a century, Entergy is a recognized leader in corporate citizenship, delivering more than $100 million in economic benefits to local communities through philanthropy and advocacy efforts annually over the last several years. With a total of 44 awards from EEI for its restoration and mutual-assistance work, Entergy remains the only utility company to have won either EEI's Recovery or Assistance Award, or both, every year since the awards began in 1998.

Rankiteo Explanation : Attack with significant impact with internal employee data leaksDescription: TALX is working with Entergy to notify former and current Entergy employees whose 2016 W-2 data have been acquired by criminals from the TALX portal. An unauthorized third party gained access to the accounts. It was done primarily by successfully answering personal questions about the affected employees in order to reset the employeesโ PINS. It gave unauthorized access to certain Entergy employeesโ online portal accounts and electronic W-2 tax forms for the tax year 2016 or earlier. TALX has arranged for two years of complimentary restoration and assistance help for affected Entergy employees. |

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.
