By Type :

The type segment is classified into firewalls, virtual private networking, hyper-scale network security, unified threat management, network management, and others. Firewalls accounted for the largest market share in 2022 as firewalls offer a wide range of features, including stateful packet inspection, URL filtering, antivirus and antimalware scanning, and deep packet inspection. The multi-layered approach allows organizations to defend against various types of threats, creating firewalls as an attractive all-in-one security solution. Additionally, firewalls offer more granular control over the DNS enquiring behavior and automatically detect accounts and resources that fail to comply with the organization's set of security rules. Firewalls are responsible to configure, monitor, and maintain security policies across the network, thus contributing notably to the dominance of the segment. For instance, in March 2021, Amazon Web Services, Inc. launched Amazon Route 53 Resolver DNS Firewall to block DNS queries for malicious domains and also provide granular control over the DNS querying. Additionally, the firewall offers two managed domain botnet command and control domains and malware domains to offer protection against threats, thus contributing notably to propel the market growth.

Virtual Private Networking (VPN) is anticipated to register the fastest CAGR in the network security appliance market during the forecast period. VPNs provide a secure method for remote users to access corporate networks over the internet. Additionally, the increasing trend of remote work and rising need for secure access to company resources from various locations, is fueling the demand for VPNs. Moreover, VPNs encrypt data transmitted between the user's device and the corporate network, safeguarding sensitive information and thus contributing to market growth. Furthermore, VPNs help users to maintain privacy by hiding the real IP addresses and routing the internet traffic through secure servers. This feature is particularly important while accessing the internet from public Wi-Fi networks or in countries with strict internet censorship, thus contributing notably in bolstering the market growth.

By Deployment:

The deployment segment is bifurcated into cloud and on-premise. Cloud-based network security appliances accounted for the largest market share in 2022 and are also predicted to witness the fastest CAGR in the upcoming years. The growth is attributed to the ability of cloud-based solutions to offer improved scalability to quickly adjust to meet the changing demands of organizations. Additionally, traditional on-premises security appliances require substantial upfront investments in hardware, maintenance, and ongoing updates. Cloud-based solutions shift the capital expense to an operational expense model, allowing organizations to pay for only the used resources. Moreover, cloud-based security appliances receive real-time updates and threat intelligence from the service provider, thus offering protection against emerging threats. Consequently, the above-mentioned benefits offered by cloud-based network security appliances are contributing notably in bolstering the market growth. For instance, in April 2023, Akamai Technologies, Inc. launched a Prolexic network cloud firewall to provide improved flexibility to the users to secure the network edge. The advanced cloud-based solution is extensively adopted in data centers, offering advanced protection against cyberattacks, hence contributing remarkably in bolstering the market growth.

By Enterprise Size:

The enterprise size segment is bifurcated into large enterprise and small-medium enterprise. Large enterprises accounted for the largest market share in 2022 as large enterprises have higher bandwidth requirements compared to small businesses. The enterprises rely on fast and reliable internet connectivity to support the operations and involve data-intensive activities including cloud computing, video conferencing, large-scale file transfers, and remote access to corporate networks. The vast network of large enterprises is subjected to cyberattacks, thus necessitating the need for advanced security appliances to provide improved protection. Network security appliances are crucial in providing the necessary defenses against cyberattacks, namely Distributed Denial of Service (DDoS) attacks, ransomware, malware, and phishing attempts. Consequently, the aforementioned reasons are contributing significantly in propelling the growth of the network security appliance market.

Small-medium enterprises are anticipated to witness the fastest CAGR in the network security appliance market during the forecast period. The growth is attributed to the increasing adoption of cloud services and e-commerce solutions by small-medium enterprises that require fast and reliable internet connectivity. E-commerce websites are highly subjected to cyberattacks, further increasing the demand for network security appliances to offer enhanced security, thus contributing in promoting the growth of the small-medium enterprises segment during the forecast period.

By End-User:

The end-user segment is classified into government, healthcare, manufacturing, BFSI, power and utilities, oil and gas, media and entertainment, and others. BFSI sector accounted for the largest market share of 21.46% in 2022 owing to the increasing number of cyberattacks on financial institutions including banks. Additionally, the growing need to provide digital privacy and sealed security solutions to financial institutions for the efficient functioning of financial management systems is further contributing to market growth. Network security appliances function by filtering and inspecting incoming and outgoing network traffic, preventing unauthorized access to the network, and protecting against various cyber threats, including malware, DDoS attacks, and intrusion attempts. Subsequently, the increasing need for advanced security solutions in financial institutions is driving the growth of the network security appliance market.

The healthcare segment is anticipated to register the fastest CAGR in the network security appliance market during the forecast period. The healthcare sector handles patient's sensitive information including health history and records of financial statements, which raises the frequency of cyber-attacks. Network security appliances monitor network traffic for suspicious activities and patterns that indicate an intrusion attempt. Additionally, the appliances detect and block or alert administrators about potential threats, helping to mitigate security breaches. Consequently, the ability of network security appliances to prevent unauthorized access of data is contributing remarkably in bolstering the growth of the healthcare segment during the forecast period.
