The short version

  • Only WireGuard has a free tier, so it costs nothing to try first.
  • Each has a real cost: DataGrail no pricing is published, and while benchmarking suggests it undercuts OneTrust for comparable scope, cost still scales with request volume and connected systems, which grow with the business.; WireGuard manual key management required; WireGuard does not provide automated peer discovery or key distribution mechanisms
  • 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.

DataGrail

  • No pricing is published, and while benchmarking suggests it undercuts OneTrust for comparable scope, cost still scales with request volume and connected systems, which grow with the business.
  • Automated fulfilment only works for systems with a supported connector, so homegrown applications and legacy databases still need manual handling, and those are usually where the awkward data lives.
  • Discovery works by observing integrations and traffic patterns, so genuinely isolated systems, offline data and files on employee machines remain invisible and outside the data map.
  • It is narrower than the enterprise privacy suites, lacking the assessment, third-party risk and wider GRC modules a large regulated organisation will also need, so it may be one of two platforms rather than the only one.
  • Deletion automation is irreversible and mistakes are unrecoverable, so teams need real confidence in identity verification before enabling it, and that caution often keeps deletion semi-manual for months after purchase.

WireGuard

  • Manual key management required; WireGuard does not provide automated peer discovery or key distribution mechanisms
  • No built-in support for address allocation or DHCP; all IP assignments must be manually configured
  • Limited to UDP; TCP encapsulation requires wrapper tools, making it unsuitable for environments blocking UDP
  • Stateless protocol design means lost packets trigger peer disconnection rather than transparent reconnection
  • Requires operational expertise to securely configure and deploy; not suitable for non-technical users without wrapper tools (Tailscale, Mullvad)

Questions people ask

Is DataGrail or WireGuard better?
Neither clearly leads. DataGrail starts at On request and WireGuard at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, DataGrail or WireGuard?
WireGuard has a free tier; the other does not. Paid plans start at On request for DataGrail and Free for WireGuard.
Does DataGrail or WireGuard run on more platforms?
DataGrail runs on Web, API. WireGuard runs on Linux, Windows, macOS, iOS, Android, FreeBSD, OpenBSD.
Can I use WireGuard for free?
Yes. WireGuard has a free tier, so you can try it without paying. DataGrail starts at On request.
What is DataGrail best used for?
DataGrail is most often used for a consumer brand whose deletion requests keep missing data in marketing tools the privacy team did not know existed, a company processing hundreds of ccpa requests a month where manual fulfilment has become a full-time job, a privacy team leaving onetrust because the platform tracked requests but staff still completed them by hand, an organisation needing evidence for a regulator that deletion actually occurred in every system, not that a ticket was closed. Of those, a consumer brand whose deletion requests keep missing data in marketing tools the privacy team did not know existed and a company processing hundreds of ccpa requests a month where manual fulfilment has become a full-time job are not what WireGuard is typically brought in for.
What can DataGrail do that WireGuard cannot?

Answered from the vendors’ own pages

DataGrail: How is DataGrail different from OneTrust?

OneTrust orchestrates the workflow; DataGrail focuses on connecting to systems and completing the request, and benchmark data suggests it prices materially below OneTrust for comparable scope.

WireGuard: Is WireGuard free?

Yes, WireGuard is free and open-source software. The Linux kernel module is licensed under GPLv2; implementations for other platforms use MIT or Apache 2.0 licences. There are no licensing fees.

Source
DataGrail: Does it find systems we do not know about?

Yes. Continuous discovery of unsanctioned tools processing personal data is its main technical claim.

WireGuard: How does WireGuard differ from IPsec and OpenVPN?

WireGuard replaces complex negotiation protocols and state machines with simple public-key cryptography. Its code is roughly 100 times smaller than IPsec, making it faster to audit, deploy, and maintain. It uses modern cryptographic primitives rather than legacy algorithms.

Source
DataGrail: What does it cost?

Not published. Pricing is quoted by request volume and connected systems, with multi-year commitments typically discounted.

WireGuard: Can I use WireGuard for a commercial VPN service?

Yes. Several commercial VPN services (Mullvad, IVPN, ProtonVPN) use WireGuard as their underlying protocol. You must implement peer management, key distribution, and endpoint selection on top of the WireGuard protocol.

Source
DataGrail: Does it cover consent as well as requests?

Yes, it includes consent management, though publishers needing certified advertising consent usually use a specialist CMP.
