Top Network Firewalls for 2023

Small companies are the target of more than half of today's cyber attacks because they often have weaker network protection, making them an easier target for hackers. According to the National Cyber Security Alliance, 60% of small and medium-sized businesses that are hacked fail within six months.

Any corporation that handles big amounts of data or connects people to the Internet must have a firewall in place. End users, customers, and data are shielded from all external parties by a firewall, allowing organizations to function without concern for cybersecurity.

Firewalls are responsible for handling a significant portion of a corporate network's inbound traffic. Despite the fact that they are not responsible for the security of the entire infrastructure, they are a vital component of network defense. Consider the environments it supports, the flexibility of its security rules, and the performance needs of your main apps and workloads when selecting a firewall for your firm.

In this article, we provide a brief introduction to network firewall options without providing a ranking. Through the selection of the appropriate firewall for your organization, you can make the best decisions.

4. Sophos Firewall

Sophos's solutions include network security, endpoint security, cloud security, and MDR. Its firewall products fall under many product categories. Firewalls and the Intercept X endpoint security solution are the most popular products offered by Sophos.

In the last year, significant firewall-related upgrades have included the introduction of the Sophos XGS line of hardware firewalls, the introduction of the Sophos ZTNA product, and the release of new software subscriptions. Additionally, Sophos has strengthened XGS performance and SD-WAN orchestration.

Sophos Firewall was designed from the start to solve some of the most pressing issues with existing firewalls. These are the most common criticisms regarding modern firewalls:

• Lack of insight into network threats and activities. Most firewalls make it difficult to access vital information and do a poor job of highlighting what is essential.

• Lack of security and functionality, or excessively difficult configuration. Most firewalls either lack the essential technology to stop the most recent sophisticated attacks or are difficult to set up, thus reducing the likelihood that they are set up correctly.

• Failure to respond to network incidents as they arise. Most firewalls give minimal, if any, visibility into the presence of network threats. Additionally, they do not react automatically when they do.

• Lack of tools to quickly configure and administer complicated SD-WAN VPN overlay networks, as well as inadequate transition management between numerous SD-WAN links in the case of a breakdown.

Sophos Firewall is superior to rival network firewalls in four significant ways:

• Exposes hidden hazards: Sophos Firewall performs a far better job of revealing hidden dangers than competing systems, thanks to its visible dashboard, robust on-box, and cloud data, and unique risk insights.

• Blocks unknown attacks: Sophos Firewall makes blocking unknown threats faster, simpler, and more effective than competing firewalls by providing a comprehensive array of sophisticated security features that are incredibly simple to configure and maintain.

• Responds instantly to incidents: Sophos Firewall with Synchronized Security responds automatically to events on the network owing to Sophos Security HeartbeatTM, which provides real-time intelligence between your endpoints and firewall.

• Optimizes your SD-WAN network: Sophos Firewall's Xstream SD-WAN features make setting up complicated SD-WAN overlay networks a simple point-and-click operation.

You can also get the most out of your applications by using automated performance-based WAN connection selection and quick, seamless link changes.

17. Huawei

Utilizing firewalls to ensure the security of carrier networks is typical practice.However, firewalls are only capable of analyzing and blocking threats based on their signatures. This technique cannot handle unknown threats adequately and may degrade device performance. This passive, single-point technique does not adequately prevent or defend against unknown threat assaults. Particularly, threats concealed in encrypted traffic cannot be efficiently recognized without violating user privacy.

Huawei next-generation firewall delivers the newest capabilities and collaborates with other security devices to proactively protect against network threats, strengthen border detection capabilities, effectively defend against advanced attacks, and tackle performance degradation issues.

The product's pattern matching and encryption/decryption service processing acceleration capabilities significantly enhance the firewall's capacity to handle content security detection and IPSec services.
