The short version
- Each has a real cost: Microsoft Defender defender Suite requires existing Microsoft 365 E3 or equivalent base licensing; 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.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Microsoft Defender
- Defender Suite requires existing Microsoft 365 E3 or equivalent base licensing
- Some Defender products use pay-as-you-go pricing with variable costs
- Prices vary based on Microsoft agreements, requiring sales contact for custom quotes
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- Pricing is unpublished and modular, so scoping is difficult without a sales engagement and the eventual cost depends on module choices that are hard to evaluate before you have seen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.

Both, deliberately. It runs data security posture management and privacy operations off one discovery catalogue, which is its main argument against buying two products.
Microsoft Defender: What add-ons are available for Microsoft Defender?
Microsoft Defender Vulnerability Management Add-on costs $2/user/month with annual commitment and includes a one-month free trial. Additional pay-as-you-go products include External Attack Surface Management, Cloud Security Posture Management, and Sentinel.

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

Yes, Microsoft Defender Suite is included in Microsoft 365 E5 at $60/user/month (paid yearly with Teams). Prices may vary based on Microsoft agreements, requiring contact with Sales for customized quotes.
SourceSecuriti: 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.
