The short version

  • Only Microsoft Sentinel has a free tier, so it costs nothing to try first.
  • Each has a real cost: Microsoft Sentinel billing is driven by the volume of log data ingested per day, so cost scales with log noise rather than with users or protected assets; Zencity social listening is structurally biased toward residents who post, so a city using the listening product without the survey product will consistently mistake volume for consensus.
  • They diverge on capability: Microsoft Sentinel covers AI-powered analytics, Zencity covers Organic social listening.
  • 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.

Microsoft Sentinel

  • Billing is driven by the volume of log data ingested per day, so cost scales with log noise rather than with users or protected assets
  • Commitment tier discounts require reserving daily ingestion capacity in advance, and a tier cannot be downgraded until 31 days have passed
  • Commitment tiers start at 100 GB per day, above what smaller estates ingest
  • Charges for Log Analytics, Logic Apps and Machine Learning are billed separately on top of Sentinel itself
  • The free allowance is only up to 5 MB per user per day for selected Microsoft 365 security logs
  • Promotional commitment pricing is time limited and locks in only until a stated end date

Zencity

  • Social listening is structurally biased toward residents who post, so a city using the listening product without the survey product will consistently mistake volume for consensus.
  • Government analysis of residents' public speech, particularly by police departments, has drawn civil liberties criticism and records request scrutiny in United States cities, and agencies need a public answer ready before signing.
  • Sentiment classification of local slang, sarcasm and non English posts is imperfect, and a misclassified theme presented in a leadership briefing can be acted on before anyone checks the underlying posts.
  • Survey sample sizes at neighbourhood level are often small, so the district level breakdowns that councils most want are the least reliable numbers in the report.
  • It reports on opinion without connecting to service delivery systems, so acting on a finding remains a separate manual process in whatever operational software the agency runs.

Answered from the vendors’ own pages

Microsoft Sentinel: How is Microsoft Sentinel pricing calculated?

Microsoft Sentinel uses a pay-as-you-go usage-based model where you pay only for data ingested, stored, and consumed. Flexible commitment tiers are available to reduce total cost of ownership, with specific rates not published on the public pricing page.

Zencity: Is this surveillance of residents?

It analyses publicly posted content and aggregated survey responses rather than private accounts, but the distinction has been contested publicly, especially for police use. Prepare an explanation before procurement.

Microsoft Sentinel: Does Microsoft Sentinel require an Azure subscription?

Yes, Microsoft Sentinel requires a Microsoft Azure subscription to operate. Pricing is handled through Azure and varies based on data consumption and the commitment tier you select. Source: https://www.microsoft.com/security/business/siem-and-xdr/microsoft-sentinel/

Zencity: Why pair listening with surveys?

Because the people who post are not representative of the people who live there. The gap between the two datasets is often the most useful output.

Zencity: What did Zencity acquire?

Elucd, in 2021, which brought community trust survey methodology used with police departments.

Zencity: Can residents find out what our city bought?

Yes. These are public contracts and several have been obtained and published through records requests.
