SSL Inspection with Firewalls: Challenges and Effective Solutions

In our ever-evolving digital landscape, the focus on cybersecurity and data integrity has never been higher. SSL inspection, which is the process of decrypting and inspecting HTTPS traffic to monitor and regulate web content, is one way organizations aim to boost their cybersecurity posture. Many businesses trust their firewalls to undertake this task, but as technology advances, this approach presents several challenges:

1. Strain on Firewall Performance

The computational load required to perform SSL inspection can be demanding, and this additional burden may affect a firewall’s core functions. If a firewall is overtaxed with decrypting and inspecting traffic, its primary responsibility—shielding your network from threats—may suffer.

2. Limited SSL Inspection Capabilities

Not all firewalls are created equal. While some might possess robust SSL inspection capabilities, others might offer limited functionality or none at all. If you’re relying on a firewall without the necessary capabilities, your organization’s web traffic remains largely unseen.

3. Emerging Encryption Technologies

With encrypted DNS (DoH) and Encrypted Client Hello becoming increasingly popular, firewalls will find it increasingly challenging to intercept and examine traffic. These encryption advancements can limit the efficacy of even the most sophisticated firewalls, rendering them less effective for SSL inspection.

Given these challenges, many experts suggest looking beyond firewalls for SSL inspection.

Proxy-Based Solutions: The Way Forward

For environments seeking comprehensive SSL inspection without overloading their firewall, proxy-based solutions are often the ideal answer. These solutions are specifically crafted to execute SSL inspection tasks, offering detailed monitoring and reporting on employee web activity.

One of the trusted names in this arena is Wavecrest Computing. With nearly three decades in the field, Wavecrest has designed tools like Cyfin and CyBlock to address the specific challenges of SSL inspection.

CyBlock stands out as a premium choice for those in need. Not only does it offer the extensive monitoring and reporting features found in Cyfin, but it can also filter web access in real-time if desired. For businesses solely seeking SSL inspection, monitoring, and reporting, CyBlock fits the bill perfectly.

In Conclusion

Relying solely on a firewall for SSL inspection can lead to potential vulnerabilities and performance issues. As encrypted web traffic becomes the norm and emerging encryption technologies come into play, the challenges will only increase. Solutions like Cyfin and CyBlock from Wavecrest Computing can help businesses rise to these challenges, ensuring robust cybersecurity while providing detailed insights into web activity. If your current setup falls short or you’re aiming to optimize SSL inspection without taxing your firewall, Wavecrest offers the specialized solutions you need.
