Firewall Trends in 2022: What to Expect for Network Protection

    skycentral.co.uk | Firewall Trends in 2022: What to Expect for Network Protection


    In today’s highly connected digital world, network security is of utmost importance. With cyber threats evolving and becoming more sophisticated, organizations need effective measures in place to protect their sensitive data and systems. One crucial component of network security is a firewall. Firewalls act as a barrier between a trusted internal network and an untrusted external network, filtering and controlling incoming and outgoing network traffic based on predefined security policies. As we enter 2022, it is important to be aware of the emerging trends in firewalls and what to expect for network protection.

    Increased Focus on Cloud-Based Firewalls

    One significant trend we can expect to see in 2022 is an increased focus on cloud-based firewalls. As more organizations adopt cloud computing and move their infrastructure to the cloud, the need for cloud-native security solutions becomes crucial. Cloud-based firewalls offer several advantages, including scalability, flexibility, and ease of management. By leveraging the cloud, organizations can dynamically adjust their firewall resources based on traffic patterns and scale them up or down as needed. Additionally, cloud-based firewalls can be integrated with other cloud services, such as threat intelligence platforms, to enhance security capabilities.

    Application-Aware Firewalls

    Another trend to watch out for in 2022 is the rise of application-aware firewalls. Traditional firewalls primarily focus on IP addresses and port numbers to control network traffic. However, with the increasing use of complex applications, this approach proves to be insufficient. Application-aware firewalls provide greater visibility and control by inspecting the content of network packets and understanding the context of the application-layer protocols being used. These firewalls can identify and block specific applications or application features that may pose security risks. This trend is particularly important as organizations rely on a wide array of web-based applications, including cloud-based collaboration tools and SaaS applications.

    Enhanced Threat Intelligence Integration

    As cyber threats continue to evolve, firewalls need to keep up by integrating advanced threat intelligence capabilities. In 2022, we can expect to see firewalls incorporating more sophisticated threat intelligence feeds and machine learning algorithms for threat detection and prevention. By leveraging threat intelligence data from reputable sources, firewalls can identify known malicious IP addresses, domains, and URLs to block, thereby significantly reducing the risk of successful attacks. Furthermore, machine learning algorithms can enable firewalls to identify anomalies and patterns in network traffic that may indicate potential threats, enabling proactive protection.

    Integrated Network and Endpoint Protection

    Networks are not the only entry points for cyber attacks; endpoints, such as laptops, desktops, and mobile devices, are equally vulnerable. In 2022, we can expect to see more integration between network and endpoint protection tools. Firewalls will play a central role in this integration, allowing for the exchange of threat intelligence information between the network and endpoint security solutions. This synergy will enable organizations to identify and respond to threats across the entire network ecosystem more effectively. For example, if a firewall detects a suspicious network connection, it can trigger an endpoint protection solution to conduct a deeper analysis of the corresponding device.

    Advanced Behavioral Analysis

    Behavioral analysis is an essential component of modern firewalls. By analyzing network traffic patterns and behaviors, firewalls can detect abnormal activities and potential security breaches. In 2022, we can expect to see advancements in behavioral analysis techniques. Firewalls will employ more sophisticated algorithms that can identify not only known patterns but also detect anomalies that may indicate novel attack vectors. This trend is critical in the face of emerging threats and zero-day attacks, where traditional signature-based approaches may fall short. Moreover, behavioral analysis can provide organizations with valuable insights into their network traffic, helping them identify inefficiencies, performance bottlenecks, and potential areas for improvement.


    As we move into 2022, the landscape of network security and firewalls continues to evolve. Cloud-based firewalls, application-aware firewalls, enhanced threat intelligence integration, integrated network, and endpoint protection, and advanced behavioral analysis are all trends to watch out for in the upcoming year. Organizations must stay informed about these trends and ensure their network protection strategies align with the latest advancements in firewall technology. By adopting these trends and investing in robust firewall solutions, organizations can enhance their network security posture and protect their valuable assets from the ever-evolving cyber threats in the digital age.
