As organizations grapple with the dual challenges of increasingly sophisticated attacks and the proliferation of hybrid networks, HMFs offer a ray of hope.

The modern threat landscape has evolved at an astonishing pace, and organizations are facing unprecedented challenges in safeguarding their digital assets. Cyber threats are no longer sporadic or unsophisticated; they have become relentless and highly advanced. To underscore the gravity of the situation, let’s delve into some alarming statistics:

  • Rise in Cyber Attacks: According to a recent report by a leading cybersecurity firm, cyber attacks have increased by 67% compared to the previous year. This sharp uptick in attacks demonstrates the urgency for organizations to fortify their defenses.
  • Complex Attack Vectors: The nature of cyber attacks has become increasingly multifaceted. Attackers are no longer limited to traditional methods but employ a combination of tactics, such as social engineering, malware, and zero-day vulnerabilities. This complexity has made it challenging for traditional security tools to keep up.
  • Targeting Nontraditional Devices: Cybercriminals are now targeting a broader range of devices beyond traditional computers and servers. IoT devices, which are becoming ubiquitous in homes and businesses, have emerged as prime targets. In 2022, there were over 15 million IoT device-related cyber attacks reported globally.
  • Shortage of Cybersecurity Professionals: The shortage of skilled cybersecurity professionals remains a persistent challenge. As organizations face a surge in cyber threats, they are grappling with the scarcity of qualified experts to defend against these attacks. Studies indicate that there will be a global shortage of 3.5 million cybersecurity professionals by 2023.

In light of these alarming trends, it is evident that organizations need to adopt innovative and comprehensive cybersecurity solutions to safeguard their networks effectively.

Coordinated Protection: The Essence of Hybrid Mesh Firewall

At the core of an HMF lies its ability to provide coordinated protection by integrating a spectrum of next-generation firewall (NGFW) solutions. These NGFWs span a wide range of deployment options, from chassis-based systems to appliances tailored for large and small sites, virtual machines, cloud-native firewalls, and Firewall-as-a-Service (FWaaS) offerings. This integrated collection of NGFWs operates in synergy to create a unified defense mechanism.

Historically, organizations have relied on on-premises firewalls or siloed NGFWs to secure different segments of their environments. This approach left room for mismatched security policies, management confusion, and vulnerabilities that attackers could exploit. In contrast, HMFs offer a cohesive solution that eliminates these shortcomings.

A key advantage of HMFs is their ability to traverse today’s multi-cloud and hybrid data center landscapes. They achieve this through a unified management console that coordinates protection across all IT domains. This console empowers enterprise IT teams to automate NGFW capabilities, such as data collection, AI-assisted deep analysis, and a unified response, without redundancy or manual overhead. In an era where the cybersecurity skills gap constrains resources, this automation is invaluable.

Moreover, HMFs establish a unified security posture that is easy to manage and devoid of coverage gaps, creating a formidable defense against attackers.

Key Considerations for Implementing a Hybrid Mesh Firewall

Whether an organization is in the process of implementing an HMF architecture or exploring the concept for the first time, several critical considerations come into play. With a plethora of information circulating about HMFs, it is essential to cut through the noise and focus on key priorities.

Assessment of Current NGFW Solutions: The first step involves a comprehensive evaluation of the existing firewall solutions and services within the organization’s environment. This assessment serves as the foundation for building an HMF architecture. Next-generation firewalls should encompass a range of features, including deep packet inspection, application control, website filtering, Quality of Service (QoS), malware detection, and zero-trust enforcement. Integration capabilities and the presence of a single, intuitive management console are equally vital.

Harnessing AI and ML: In the face of an expanding threat landscape, the incorporation of Artificial Intelligence (AI) and Machine Learning (ML) capabilities is imperative. These technologies empower NGFWs within HMFs to detect and defend against both known and unknown threats effectively. AI and ML enable HMFs to classify applications, web URLs, users, devices, malware, and more while automating policy enforcement across domains. The heart of HMF automation lies in AI and ML, significantly reducing manual effort and enhancing protection across IT and Operational Technology (OT) environments.

Integration with Enterprise-Wide Security: While HMFs offer robust security, they are only one piece of the broader security puzzle. Modern enterprises require a comprehensive, integrated cybersecurity approach that extends across the entire network infrastructure. This approach encompasses firewalls, endpoint protection, secure access, and cloud security. To maximize effectiveness, HMF deployments should seamlessly integrate with the overall security infrastructure, promoting unified management and visibility.

Flexible Pricing Models: Business needs evolve rapidly, necessitating the flexibility to deploy a range of firewalls without commitment to a single form factor. Usage-based pricing models, such as Fortinet’s FortiFlex program, empower organizations to pay only for the services they utilize. This flexibility allows them to scale security services according to dynamic requirements, effectively managing budgets in the ever-evolving landscape of network security.

Third-Party Validation: In a crowded cybersecurity marketplace, determining the most suitable solutions for specific needs can be challenging. Third-party validation is a valuable tool for evaluating product efficacy. Independent testing organizations offer objective assessments of security solutions, devoid of commercial bias. Organizations exploring NGFW and HMF vendors should prioritize those who have undergone third-party testing, providing transparent and unbiased insights into their solutions.

Final thoughts:

In conclusion, the relentless evolution of cyber threats necessitates innovative solutions to safeguard enterprise networks comprehensively. Hybrid Mesh Firewalls (HMFs) represent a paradigm shift in network security, offering coordinated protection, automation, and integration across diverse IT domains.
