The short version
- Only Wireshark has a free tier, so it costs nothing to try first.
- Each has a real cost: BigID pricing scales with data sources and volume, so the cost rises exactly as the estate you need to scan grows, and the modules shown in a demo, including AI security posture and headless deployment, are frequently separate licences that appear only in the final quote.; Wireshark free and open source under the GNU GPL; downloadable without paying any license fee, no commercial tier
- They diverge on capability: BigID covers Structured and unstructured scanning, Wireshark covers Deep packet inspection.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
BigID
- Pricing scales with data sources and volume, so the cost rises exactly as the estate you need to scan grows, and the modules shown in a demo, including AI security posture and headless deployment, are frequently separate licences that appear only in the final quote.
- Scanning large unstructured estates is slow and computationally expensive, so most organisations sample rather than scan everything, which reintroduces uncertainty into the very question they bought the tool to settle.
- Classification accuracy on messy unstructured content requires tuning, and out of the box false positives on things like reference numbers create a large triage backlog that a small governance team cannot clear.
- It discovers and reports but does not remediate, so realising value requires a separate process and often separate tooling to actually delete, restrict or move the data it flags.
- It is built for large enterprises and both the price and the administrative overhead are disproportionate below a few thousand employees, where a lighter DSPM tool covers the security use case for far less.

Answered from the vendors’ own pages
BigID: What does BigID cost?
It is quoted by data source count and volume. Reported contracts run from roughly 15,000 to 175,000 US dollars a year, and add-on modules such as AI security posture are licensed on top.
Wireshark: Is there a cost to download and use Wireshark?
No, Wireshark is completely free. It's distributed under the GNU General Public License version 2, making it "free software" with no demo limitations. The full version is available at no cost.
SourceBigID: Does it handle unstructured data?
Yes, and that is its main advantage. It classifies data in files and shares and correlates findings back to individuals, not just to data types.
Wireshark: What support options are available for Wireshark users?
Wireshark offers multiple support channels including mailing lists, an active Discord community, the Ask Wireshark Q&A platform, comprehensive documentation, a user guide, and developer resources for those needing technical assistance.
SourceBigID: Will it delete the data it finds?
Not by itself in most deployments. It identifies and routes findings; deletion and remediation happen through your own processes or connected systems.
Wireshark: Are there different pricing tiers or subscription levels?
Wireshark does not offer pricing tiers or subscriptions. There is one free version available to all users regardless of use case, personal, professional, or organizational.
SourceBigID: Is it a privacy tool or a security tool?
Both are sold from the same discovery core. Buyers increasingly come from security wanting data security posture management rather than from legal wanting privacy.
