Webinar “Decrypting Network Traffic – How to Peek Into Encrypted Packets Using TLS 1.3 with ExtraHop”

In a world where most network traffic is encrypted today, it becomes essential to regain control and context without compromising security and performance. 

During the webinar, we will show how to regain visibility of what is really happening on the network in the era of ubiquitous encryption — even when the traffic is protected by TLS 1.3. We will discuss what “blind spots” encryption creates and why merely monitoring logs or endpoints is not enough for quickly detecting incidents and diagnosing application problems. 

Through examples, we will explain how ExtraHop RevealX combines NDR and NPM capabilities, providing a consistent picture of security and performance, and how it performs TLS 1.3 decryption to ensure insight into communication content and context without losing scalability. We will also discuss good implementation practices: from architecture for large traffic volumes to testing effectiveness in a real-world environment. Finally, we will summarize key benefits and answer participants’ questions. 

1. ExtraHop RevealX – the visibility center for encrypted traffic

• The role of RevealX as a “radar” for the entire network: combining NDR and NPM
• Why full visibility of TLS 1.2 / TLS 1.3 traffic is critical for SOC

2. What can and cannot be seen in encrypted traffic

• “Blind spots” in encrypted networks – limitations of classic tools without NDR
• Risks hidden in TLS metadata, lateral movement, and atypical communication patterns
• Consequences of not correlating events at the network level: delayed detection, more false alarms

3. Principles of TLS 1.3 decryption in ExtraHop

• How ExtraHop implements TLS 1.3 traffic decryption – architecture, methods, requirements
• Principles of safe decryption:
  • which segments and applications are decrypted,
  • what keys and mechanisms are used,
• The impact of decryption on performance: how ExtraHop ensures full insight without performance drop

4. When and why to decrypt TLS 1.3 traffic – practical criteria

• Clear decision criteria: when decryption makes the most sense (and when it does not)
• Real scenarios:
  • detecting attacks in encrypted traffic,
  • incident analysis,
  • monitoring key business applications.
• How to maximize visibility while maintaining compliance (GDPR, internal policies, data segmentation)

5. Combined view of security and performance

• Event correlation across the entire network: fewer false alarms, faster SOC decisions
• Combining the security perspective (NDR) and performance (NPM) on one screen

6. Scaling and reliability of decryption implementation

• How to design ExtraHop deployment for growing TLS 1.3 volumes

7. Summary and Q&A

• Key takeaways: principles of TLS 1.3 decryption, security, compliance, and performance
• Participants’ questions and discussion of specific cases from their environments
