The short version

  • Only Arc has a free tier, so it costs nothing to try first.
  • Each has a real cost: Arc no longer receiving active feature development as of May 2025, entering maintenance mode; Securiti value depends entirely on connector coverage and completed scanning, so the first useful data map commonly takes months and stalls whenever a data owner will not grant access to a system.
  • They diverge on capability: Arc covers Spaces and Profiles, Securiti covers Sensitive data discovery.
  • 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.

Arc

  • No longer receiving active feature development as of May 2025, entering maintenance mode
  • Limited cross-platform availability compared to mainstream browsers
  • Smaller ecosystem of extensions compared to Chrome
  • Focused on macOS and Windows, with limited iOS support

Securiti

  • Value depends entirely on connector coverage and completed scanning, so the first useful data map commonly takes months and stalls whenever a data owner will not grant access to a system.
  • Usage-based pricing tied to data volume means costs rise as the estate grows rather than as the security programme matures, and organisations with large but low-risk data lakes pay for scanning they do not need.
  • The breadth across DSPM, privacy and AI governance means each individual module is competing with a specialist, and buyers who only need one of the three often find a focused tool does that job better for less.
  • Classification accuracy on unstructured and free-text data requires tuning, and untuned deployments generate false positives that erode trust in the catalogue precisely when teams are being asked to act on it.
  • Pricing is unpublished and modular, so scoping is difficult without a sales engagement and the eventual cost depends on module choices that are hard to evaluate before you have seen your own data map.

Answered from the vendors’ own pages

Arc: Does Arc Browser cost anything to use?

Arc is completely free to download and use with no subscription required. All features are available at no cost.

Source
Securiti: Is Securiti a DSPM tool or a privacy tool?

Both, deliberately. It runs data security posture management and privacy operations off one discovery catalogue, which is its main argument against buying two products.

Arc: What operating systems does Arc support?

Arc is available on macOS, Windows, and iOS. Windows and mobile versions are available for download.

Source
Securiti: What does it cost?

Not published. Pricing is modular and usage based, quoted by data volume and selected modules, and it is also available through the AWS marketplace.

Arc: Will Arc continue to receive new features?

As of May 2025, Arc entered maintenance mode with no new features planned. The Browser Company's focus has shifted to Dia browser, though Arc continues to receive security updates.

Source
Securiti: How long until it is useful?

Expect months, not weeks. The limiting factor is configuring connectors and getting access approvals to the systems you most want scanned.

Securiti: Does it govern AI use?

Yes, it includes controls over data flowing into models and retrieval pipelines, which is increasingly the reason enterprises shortlist it.
