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

Postman

  • Free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans
  • Only 25 collection runs per month and 1,000 API calls/month on free tier
  • Removed local-only Scratch Pad mode in 2023, forcing cloud account creation and sync
  • Requires Postman account and internet connection for most features
  • Cloud-first architecture with mandatory syncing to Postman's cloud servers
  • No CI/CD integration or advanced security features on free plan

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.

Postman: What is the cost of Postman?

Postman has a free plan limited to 1 user, 25 collection runs/month, 1,000 API calls/month. Team plans start at $14/user/month for Basic. Professional at $29/user/month, and Enterprise at $49/user/month.

Source
BigID: 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.

Postman: Can I use Postman offline?

Postman requires an internet connection to sync collections to the cloud. Since 2023, the Scratch Pad local-only mode was removed. Users must sign in with a Postman account, and collections sync to cloud by default. Offline work is possible but limited without cloud sync features.

Source
BigID: 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.

Postman: Does Postman have team collaboration?

Team collaboration is not available on the free plan (limited to 1 user). Team plans start at $14/user/month and include shared workspaces, real-time collaboration, and team management features.

Source
BigID: 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.

Postman: What are the free plan limits?

Free plan allows: 1 user only, 25 collection runs per month, 1,000 API calls/month, and 1,000 mock server calls/month. No CI/CD integration or advanced security features.

Source
Postman: Does Postman work with other development tools?

Postman integrates with Git repositories, offers a Node.js runner (Newman) for automation, and connects with popular CI/CD platforms. Teams using git-native workflows may prefer alternatives like Bruno.
