Sources and methodology
The package review checks technology attribution, organization or site identity, duplicates and public-source support. Source classes can overlap; counts below use the scope named in each row and are not market-share estimates.

|---|---|---|
| First-party web policies, processor lists and DPAs | 88 | Reviewed public evidence within the recorded property or workload; execution and payment remain unverified. |
| First-party PDFs | 6 | Reviewed public evidence within the recorded property or workload; execution and payment remain unverified. |
| First-party product/help documentation | 4 | Reviewed public evidence within the recorded property or workload; execution and payment remain unverified. |

No public sample is offered for this package. Ask to review the delivery scope before buying.
Limitations of this cohort
- Public sources do not verify paid subscriptions, organization-wide deployment or purchasing intent.
- Source retrieval dates record access; they do not make an older statement or historical deployment current.
- Published contact channels do not establish outreach permission, mailbox deliverability or purchasing authority.
- The cohort is not complete coverage. Public signals and vendor statements do not prove current paid use, runtime execution, buying intent, deliverability or outreach permission.
- Source-fetch dates do not refresh historical customer stories or retained observations. Recheck a company's present use before acting.
