11 Tools Used by Cybersecurity Teams in Top MNCs

Today, as industries continue to undergo digital transformation at a rapid pace, cybersecurity has emerged as one of the key building blocks of the business landscape, especially among large multinational corporations (MNCs). Not only do they store and manage large volumes of sensitive data and operate across multiple geographical locations, but they also rely on interconnected systems to connect to one another. Due to these factors, they are prime targets for cyberattacks such as ransomware, phishing, insider threats, and advanced persistent threats (APTs). MNCs are rapidly installing an increasing number of best in class cybersecurity technologies to protect themselves against these new and growing threats; furthermore, these tools have a great deal of value for individuals beginning their careers in cybersecurity.

Cybersecurity teams in leading MNCs defend themselves from these evolving threats through the use of a robust ecosystem of tools that provide the following functionalities: monitoring, detection and prevention, and incident response. All of these tools serve to help identify vulnerabilities, but they also help to provide real-time protection and quick response times to incidents that occur.

This blog will discuss 10 of the most common tools used by leading MNCs’ cybersecurity teams to establish and maintain an effective enterprise security program. We will examine tool capabilities and discuss how those capabilities translate into critical components of a comprehensive enterprise security strategy.
