Generating GDPR compliant Wireshark captures

We can generate GDPR compliant Wireshark captures: we can make any wireshark capture "anonymous". This means we can generate based on an existing Wireshark capture a new wireshark capture where all customer IP addresses are replaced by unique 10.x.x.x IP addresses. This way, no customer details are visible anymore.

We can also overwrite specific data inside wireshark packets with e.g. xxx. We support this for the SIP protocol and the RTP protocol. Other protocols feasable on demand. Just send us an email.

Anonymize your VoIP Wireshark captures

Lets face it: a Wireshark VoIP capture contains a lot of personal data. Phone numbers, names, who is calling who, IP addresses, (hashed) digest passwords and if RTP is present it contains even the full voice stream of what was said during a phone call. Sensitive information that you don't want to pass to any third party.

However, if you face any VoIP issues, the helpdesk of your external partner will ask for such Wireshark captures.

Many customer fear to share so much personal and company sensitive information with third parties.

What if you could convert your existing wireshark capture to a wireshark capture that still contains all SIP messages, errors, warnings, flows etc, but where the sensitive info was by some magic replaced?

If that sounds like heaven to you, then the VoIP AnalyzerTool will fit you like a glove.

We support following:

hashed digest passwords responses are overwritten with xxx
user names are overwitten with xxx
phone numbers are overwritten with xxx
customer IP addresses are overwritten with with a unique 10.x.x.x value
RTP voice is overwritten with a new anonymous voice sample

Anonymize RTP voice packets

The VoIP Analyzer Tool can anonymize RTP speech packets inside a wireshark file

RTP headers are not changed, only the speech samples are replaced
RTP packet drop, jitter, delay etc is still exact the same as inside the original RTP packets

EU: General Data Protection Regulation - GDPR compliant Wireshark captures

Brazil: Lei Geral de Proteção de Dados - LGPD compliant Wireshark captures

The GDPR regulation states that personal data cannot be shared with 3rd parties just like that. Simular for the LGDP regulation.

Privacy issues will arise when you want to share a Wireshark capture with a 3rd party e.g. to receive support on any VoIP or network issue.

With the VoIP Analyzer Tool you can make any Wireshark VoIP trace anonymous, while the original SIP message types, the timing, the flow etc is still unchanged. The only thing that is overwritten automatically are the personal data like phone numbers, names, IP addresses etc.
