The traditional Virtual Private Network (VPN) has long been considered the gold standard for secure remote access, serving as a cornerstone of cybersecurity strategies for decades. However, as cyber threats evolve and digital infrastructures become increasingly complex, this once-reliable solution is showing concerning vulnerabilities that organizations can no longer afford to ignore.
The attack surface of traditional VPNs presents several significant concerns that demand attention from organizations seeking to protect themselves against increasingly sophisticated threats. In this blog post, we will explore why upgrading and separating duties for infrastructure are essential in reducing the risk associated with these networks.

Breaches: The New Normal
In today's threat landscape, experiencing a breach is no longer a matter of if, but when. This stark reality is supported by troubling statistics: according to IBM's latest research, the average cost of a data breach has risen to approximately $4.88 million. More concerning still, 40% of breaches now involve data stored across multiple environments, with cloud-based data breaches carrying the highest price tag at $5.17 million.
The implications of these statistics extend beyond immediate financial impact. Organizations must now consider the long-term consequences of data exposure, particularly in light of emerging quantum computing threats. The rise of "steal now, decrypt later" attacks presents a particularly insidious challenge, where threat actors harvest encrypted data today with the intention of decrypting it once quantum computing capabilities become available.
Considering this impact, it is essential for organizations to adopt preemptive cyber defense strategies that minimize and consolidate their VPN attack surface and limit the potential damage in the event of an incident. This means we must use the network properly, to segment the multi-cloud, create defensible security architectures that cannot easily be attacked, and deliver strong resilience to threats and threat actor techniques.
The Multi-Function Firewall Dilemma
The reliance on multi-function firewalls (MFFs) as the primary defense mechanism for traditional VPNs has created a complex web of security challenges. Modern operating systems and applications come equipped with their own security features, including intrusion detection, anti-malware capabilities, and application-level sandboxing. When these native security features interact with MFF functions, they often create a tangled mess of conflicts and redundancies.
This complexity manifests in several critical ways. Performance suffers as resource-intensive rule processing creates bottlenecks in network traffic. Security teams struggle with visibility, finding themselves unable to effectively monitor and analyze security events across multiple functions. The consolidated nature of MFFs often creates significant blind spots, making it difficult to identify the root cause of security incidents or maintain comprehensive audit trails.
1. Overlapping Security Functions
Many modern operating systems and applications have multiple security functions built-in, such as intrusion detection and prevention, antivirus software, and sandboxing. But these features often overlap or conflict with one another when implemented in conjunction with MFFs. Clear separation of duties, even in software, matters.
2. Performance Impact
Multi-function firewalls can introduce significant performance overhead due to the complexity of their rules and rule engines and the need for frequent updates and maintenance to avoid zero-day exploits. Secure remote access that offers built-in defense is needed.
3. Lack of Visibility
With multiple security functions competing for resources, it is challenging to gain a comprehensive understanding of an organization's overall security posture.
The Path Forward: A Modern Security Infrastructure
The future of network security lies in preemptive cybersecurity measures and innovative technologies like Dispersive Stealth Networking. This approach moves beyond traditional reactive security models to create a more resilient and proactive defense strategy.
Dispersive Stealth Networking represents a paradigm shift in how we think about secure communications. Unlike traditional VPNs that rely on a single encrypted tunnel, Dispersive Stealth Networking splits network traffic into multiple streams, dynamically routing them through different paths. This approach not only makes it exponentially more difficult for attackers to intercept or manipulate network traffic but also provides built-in redundancy and improved performance.
The preemptive cybersecurity aspect of this new approach focuses on identifying and mitigating potential threats before they can materialize. This includes continuous network monitoring, threat hunting, and the use of advanced analytics to detect patterns that might indicate impending attacks. By moving security operations into a proactive state, organizations can address vulnerabilities and potential attack vectors before they can be exploited.

To mitigate these issues and reduce the attack surface associated with traditional VPNs, organizations should adopt more sophisticated but easy to deploy solutions that prioritize separation of duties, consolidating and protecting infrastructure, signaling and key management and upgrade their infrastructure accordingly.
This may involve:
1. Segmenting and Isolating the Infrastructure itself (VPN Self-Protection): Divide critical systems and data into separate segments to limit lateral movement in case of a breach. Traditional VPNs are vulnerable, because today, the protocols themselves are the attacker’s exploit target.
2. Implementing Least Privileged Access: Grant users only the necessary permissions for their tasks, reducing the risk of insider threats.
Conclusion
The traditional VPN-based approach to network security is no longer sufficient in today's threat landscape. By embracing preemptive cybersecurity measures and innovative technologies like Dispersive Stealth Networking, organizations can significantly enhance their security posture and better protect themselves against both current and emerging threats.
The key to success lies in moving beyond reactive security measures to a more proactive, comprehensive approach. Organizations that embrace these changes and implement modern security architectures will be better positioned to face the challenges of tomorrow's threat landscape.
The time for change is now. As cyber threats continue to evolve and become more sophisticated, organizations must adapt their security strategies accordingly. The layering of preemptive cybersecurity measures like Dispersive’s Stealth Networking provides a robust foundation for this evolution, enabling organizations to stay ahead of threats rather than constantly playing catch-up.
