Firewalls have been a staple in network security for decades, but as technology evolves, so do the threats to our networks. Traditional firewalls are no longer enough to protect against modern cyber attacks. That’s where next-generation firewalls (NGFWs) come in. In this article, we’ll explore the latest security features in firewalls and why NGFWs are essential for network protection.
Fisch Solutions team of network engineers provide Network and Firewall Support to businesses around New York, New Jersey, and Connecticut with the latest tools and technologies.
The Evolution of Firewalls
Traditional Firewalls
Traditional firewalls were designed to monitor and control incoming and outgoing network traffic based on predetermined rules. They were effective at blocking known threats, but they lacked the ability to detect and prevent more sophisticated attacks.
Next-Generation Firewalls
Next-generation firewalls (NGFWs) are the latest iteration of firewalls, designed to provide more advanced security features. They combine traditional firewall capabilities with additional security features such as intrusion prevention, malware protection, and application control.
NGFWs use deep packet inspection (DPI) to analyze network traffic at a granular level, allowing them to identify and block malicious activity. They also have the ability to monitor and control applications, providing better visibility and control over network traffic.
The Latest Security Features in Firewalls
SASE Replacing VPNs
SASE, which stands for Secure Access Service Edge, is a modern approach to network security that combines network security functions with wide-area networking (WAN) capabilities to support the dynamic secure access needs of organizations. SASE is designed to provide secure access to applications and data for users, regardless of their location. This is achieved by moving security services to the cloud and delivering them as a service, rather than relying on traditional on-premises security appliances. SASE aims to simplify network security and improve performance by providing a unified, cloud-native security platform that can adapt to the changing needs of modern businesses.
SASE is gradually replacing traditional Virtual Private Networks (VPNs) as organizations shift towards a more cloud-centric and mobile workforce. Unlike VPNs, which often backhaul traffic to a central data center for security inspection, SASE offers a more direct and efficient way to secure network traffic by providing security services closer to the user. This approach not only enhances security but also improves performance and user experience, especially for remote workers accessing cloud-based applications. By consolidating networking and security services into a single cloud-delivered solution, SASE offers a more scalable, flexible, and cost-effective approach to network security in today’s digital landscape.

Threat Prevention
One of the most significant advancements in NGFWs is their ability to prevent threats before they can cause harm. Traditional firewalls rely on static rules to block known threats, but NGFWs use advanced techniques such as behavioral analysis and machine learning to identify and block unknown threats.
NGFWs can also detect and prevent threats at multiple points in the network, including the network perimeter, internal network, and even in encrypted traffic. This multi-layered approach to threat prevention is crucial in today’s threat landscape, where attacks can come from anywhere.
Network Protection
NGFWs provide comprehensive network protection by combining traditional firewall capabilities with additional security features. They can block malicious traffic, prevent unauthorized access, and detect and prevent threats in real-time.
NGFWs also have the ability to segment networks, creating virtual firewalls within a single physical firewall. This allows for more granular control over network traffic and helps contain any potential threats.
Application Control
With the rise of cloud-based applications and the increasing use of personal devices in the workplace, traditional firewalls are no longer enough to control network traffic. NGFWs have the ability to identify and control applications, allowing organizations to block or limit access to certain applications.
This feature is especially useful for organizations that want to restrict access to non-work-related applications or limit the use of bandwidth-intensive applications.
Advanced Threat Intelligence
NGFWs use advanced threat intelligence to stay ahead of emerging threats. They can gather information from multiple sources, including threat feeds, security blogs, and social media, to identify and block potential threats.
This real-time threat intelligence allows NGFWs to adapt and respond to new threats quickly, providing better protection for organizations.
Centralized Management
NGFWs offer centralized management, allowing organizations to manage and monitor their entire network from a single console. This makes it easier to enforce security policies, track network activity, and respond to threats.
Centralized management also allows for better visibility into network traffic, making it easier to identify and respond to potential threats.

Why Your Organization Needs an NGFW
Protection Against Advanced Threats
As cyber attacks become more sophisticated, traditional firewalls are no longer enough to protect against them. NGFWs provide advanced threat prevention capabilities, making them essential for organizations that want to stay ahead of emerging threats.
Better Visibility and Control
NGFWs offer better visibility and control over network traffic, allowing organizations to identify and respond to potential threats quickly. This is especially important for organizations that deal with sensitive data or have compliance requirements.
Cost-Effective Solution
NGFWs offer a cost-effective solution for network security. By combining multiple security features into a single device, organizations can save on hardware and maintenance costs.
Simplified Management
With centralized management, NGFWs make it easier to manage and monitor network security. This saves time and resources, allowing IT teams to focus on other critical tasks.
New York Firewall and Network Support, How to Choose which one.
When choosing an NGFW for your organization, there are a few key factors to consider:
Security Features
The first and most crucial factor to consider is the security features offered by the NGFW. Look for features such as threat prevention, network protection, and application control.
Scalability
As your organization grows, so will your network. Make sure the NGFW you choose can scale to meet your future needs.
Integration with Existing Systems
NGFWs should integrate seamlessly with your existing systems, such as your network infrastructure and security tools. This will ensure a smooth implementation and reduce the risk of compatibility issues.
Ease of Management
Choose an NGFW with a user-friendly interface and centralized management capabilities. This will make it easier to manage and monitor your network security.
