A next-generation firewall (NGFW) is a part of the third generation of firewall technology that is implemented in either hardware or software and is capable of detecting and blocking sophisticated attacks by enforcing security policies at the application, port and protocol levels.

Protecting organizations from cyberattacks starts with a next-generation firewall

Enforce consistent, best-in-class network security to protect applications hosted on-premises and in public clouds. Prevent inbound threats, enforce segmentation and microsegmentation, and protect against data exfiltration while running at DevOps speed and scale.

Like “machine learning” and “AI,” Zero Trust has become one of cybersecurity’s latest buzzwords. With all the noise out in the market, it’s imperative to understand what Zero Trust is, as well as what Zero Trust isn’t.
Zero Trust is a strategic initiative that helps prevent successful data breaches by eliminating the concept of trust from an organization’s network architecture. Rooted in the principle of “never trust, always verify,” Zero Trust is designed to protect modern digital environments by leveraging network segmentation, preventing lateral movement, providing Layer 7 threat prevention, and simplifying granular user-access control.

Zero Trust was created by John Kindervag, during his tenure as a vice president and principal analyst for Forrester Research, based on the realization that traditional security models operate on the outdated assumption that everything inside an organization’s network should be trusted. Under this broken trust model, it is assumed that a user’s identity is not compromised and that all users act responsibly and can be trusted. The Zero Trust model recognizes that trust is a vulnerability. Once on the network, users – including threat actors and malicious insiders – are free to move laterally and access or exfiltrate whatever data they are not limited to. Remember, the point of infiltration of an attack is often not the target location.
