The short version

  • 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.; ExpressVPN ownership passed in 2021 to Kape Technologies, formerly Crossrider, whose earlier browser extension platform was widely used to distribute adware, and Kape also owns VPN review publications, so nominally independent rankings a buyer consults may originate inside the same corporate group.
  • They diverge on capability: BigID covers Structured and unstructured scanning, ExpressVPN covers TrustedServer.
  • Prices and features above were last checked on 31 August 2026.

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.

ExpressVPN

  • Ownership passed in 2021 to Kape Technologies, formerly Crossrider, whose earlier browser extension platform was widely used to distribute adware, and Kape also owns VPN review publications, so nominally independent rankings a buyer consults may originate inside the same corporate group.
  • In 2021 the company's then chief information officer was named in a United States Department of Justice deferred prosecution agreement over work for a foreign government's offensive cyber programme and remained in post, which is a governance fact that sits uncomfortably alongside a product sold entirely on trust.
  • Audits are point-in-time engagements against an agreed scope, so they establish that specified servers and code matched the stated policy when examined, not that the infrastructure behaves the same way today or under different ownership.
  • Several country locations are virtual, meaning the hardware physically sits elsewhere, and after India's 2022 directive requiring VPN providers to retain subscriber data ExpressVPN withdrew its Indian servers, so an Indian connection is routed through hardware in another country, which matters if you need genuine in-country routing.
  • There is no port forwarding and no dedicated IP option, so seeding torrents, hosting a service behind the tunnel and any inbound connection do not work, and users who need those capabilities have to use a different provider.

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.

ExpressVPN: Who owns ExpressVPN?

Kape Technologies, which acquired it in 2021. Kape was previously named Crossrider and also owns CyberGhost, Private Internet Access and Zenmate, along with the review sites vpnMentor and Wizcase.

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.

ExpressVPN: Is the British Virgin Islands jurisdiction actually useful?

It has no mandatory data retention law and is outside the Five, Nine and Fourteen Eyes arrangements, which is the reason it was chosen. It also means limited practical legal recourse for a subscriber, so the jurisdiction protects the company's ability to hold no data rather than protecting you against the company.

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.

ExpressVPN: Has the no-logs claim been audited?

Yes, repeatedly. PwC and KPMG have examined the no-logging claims and the TrustedServer architecture, and Cure53 has reviewed the applications, extension and protocol. The reports are published.

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.

ExpressVPN: Can I torrent with it?

Yes, peer-to-peer traffic is permitted on the network, but there is no port forwarding, so you can download but you cannot accept inbound connections and seeding performance suffers as a result.

ExpressVPN: Does it work in China or similar networks?

Sometimes, using obfuscated connection modes, but no provider can guarantee this and availability changes without warning. Treat it as best effort and have a fallback.
