The short version

  • Only AdBlock Plus has a free tier, so it costs nothing to try first.
  • Each has a real cost: AdBlock Plus acceptable Ads allowlist model generates controversy over ad filtering conflicts of interest; 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: AdBlock Plus covers Ad blocking, Securiti covers Sensitive data discovery.
  • Prices and features above were last checked on 31 August 2026.

  • A privacy team automating deletion requests across dozens of systems where the hard part is knowing where a person appears at allnot AdBlock Plus

  • A company putting internal data into retrieval-augmented AI applications and needing to prove that regulated fields are not reaching the modelnot AdBlock Plus

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

AdBlock Plus

  • Acceptable Ads allowlist model generates controversy over ad filtering conflicts of interest
  • Smaller feature set compared to open-source alternatives like uBlock Origin
  • Less customization and dynamic filtering compared to uBlock Origin
  • Mobile version less comprehensive than desktop extension
  • Chrome version increasingly limited due to Manifest V3 migration

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  • Pricing is unpublished and modular, so scoping is difficult without a sales engagement and the eventual cost depends on module choices that are hard to evaluate before you have seen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

AdBlock Plus: What does Adblock Plus block?

Adblock Plus blocks banner ads, pre-roll and mid-roll video ads on YouTube, pop-ups, sidebar ads, and most standard display formats. With Acceptable Ads disabled and EasyPrivacy enabled, it achieved a 100/100 score on AdBlock Tester in April 2026.

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.

AdBlock Plus: What browsers does Adblock Plus support?

Adblock Plus is available for Chrome, Edge, Firefox, Opera, Safari, and Yandex Browser.

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.

AdBlock Plus: Is there a premium version of Adblock Plus?

Yes. Adblock Plus Premium costs $40 annually or $4 per month and allows users to block cookie consent pop-ups, while the free version includes core ad blocking.

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.

AdBlock Plus: What is Acceptable Ads?

Acceptable Ads is an opt-in setting that allows advertising Adblock Plus deems unobtrusive to display on websites; it is disabled by default but can be toggled in Settings.

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.
