All About Deep Packet Inspection and Its Role in Modern Web

January 2022

With malware and web attacks becoming more common than ever before, there has perhaps never been a more pertinent time to revisit and beef up your organization’s cybersecurity strategy. As part of your cybersecurity solutions, you may also want to implement deep packet inspection (DPI) for added peace of mind and protection against data leaks, malware, and other potential security threats.

What Is Deep Packet Inspection?

Specifically, DPI refers to a method of examining and filtering traffic as it passes through a “checkpoint” on your server. Deep packet inspection is the most thorough filtering method currently in existence. In addition to looking at the source IP address, port number, destination IP address, and other basic information, DPI looks even further at individual packets and their data and metadata.

As a result of this deeper inspection, DPI can often identify threats that could otherwise be overlooked as traffic passes through a server. This can include data exfiltration attempts, malware, criminal command communications, and content policy violations.

When implemented and carried out properly, DPI can help to reduce the risk of your organization falling victim to a data leak or even being infiltrated by malware. Meanwhile, the greater visibility offered by DPI makes it possible to block peer-to-peer downloaders from accessing your server.

Deep Packet vs. Traditional Stateful Packet Inspection

If you already use stateful packet inspection as part of your cybersecurity strategy, you may be wondering whether it’s worth making the switch to DPI. The reality is that DPI offers a much greater level of security than traditional methods of packet inspection. That’s because stateful packet inspection can only look at surface-level information, such as incoming/destination IP addresses and port numbers. It is not able to inspect packet metadata. 

Because DPI can look more closely at a more significant collection of data, it is more effective in identifying and blocking potential security threats when compared to stateful packet inspection alone.

The Importance of Dedicated Hosting in Your Cybersecurity Strategy

Choosing the right packet inspections strategy is only one component of beefing up your cybersecurity. There are plenty of other cybersecurity tips worth keeping in mind if you want to protect your organization from any number of growing online threats.

If you haven’t already, for instance, now is the time to switch to a dedicated server. By hosting your site on a dedicated hosting plan, you can enjoy unrivaled security features that give you added protection and peace of mind — especially when compared to shared or cloud hosting solutions.
