How much electronic sweeps cost in Brazil: what public contracts show
By BlackSweep team · Published
In the Brazilian public procurement we analyzed, an electronic sweep service cost from R$ 4,000 to R$ 131,000, depending on area and scope. The equipment is expensive: a full kit cost R$ 495,000 to R$ 620,000 each, and a non-linear junction detector had a median of R$ 320,000. The figures come from 51 items published on Brazil's PNCP portal between 2023 and 2026.
- Sweep service: lowest and highest contract
- R$ 4,000 – R$ 131,000
- Full kit: lowest and highest price
- R$ 495,000 – R$ 620,000
- Non-linear junction detector: median
- R$ 320,000
- Technical training: median per seat
- R$ 17,500
Main findings of the study
- Service prices vary 33-fold between contracts. We found only 3 service engagements: R$ 4,000 (selected area, Creci-MG), R$ 43,650 (physical premises, Cremesp) and R$ 131,000 (sweep, physical inspection and phones at headquarters and units, TJES). The sample is small and scopes differ.
- The full kit became 14% to 25% more expensive from September 2025. All 11 purchases through July 2025 were at R$ 495,000 per kit. The next 8 ranged from R$ 562,600 to R$ 620,000, with a R$ 600,000 median. Kit composition may vary between purchases.
- The largest purchase totals R$ 26,010,000. The Ministry of Justice awarded 45 kits in 2026 at R$ 562,600 each, plus R$ 15,400 of training per kit. In December 2025 the same ministry had registered up to 34 kits at R$ 580,000, a R$ 19,720,000 ceiling.
- A non-linear junction detector costs R$ 204,790 to R$ 385,100. The median of 13 purchases is R$ 320,000. This is the instrument that finds powered-off electronics.
- A professional spectrum analyzer has a R$ 430,200 median. The R$ 430,200 figure repeats in 4 of 7 purchases, and the OSCOR Green is named in two of them.
- Training an operator costs R$ 15,500 to R$ 19,500 per seat. The median is R$ 17,500 across 9 technical training engagements.
- Most purchases have no competition. 40 of 51 items were contracted without bidding, the route Brazilian law allows when competition is not feasible[1]. A single supplier appears in 26 of the 28 contracts in the dataset.
What these numbers mean if you are hiring a sweep
Prices cannot be compared without scope. A January 2024 Folhapress report cites about R$ 2,000 per service, and detectors sold from R$ 100 that are "much less sophisticated"[2]. The public contracts above run from R$ 4,000 to R$ 131,000. Ask in writing for the area covered, the techniques used and the deliverable.
Ask which equipment will be on site. A low quote does not prove poor work and a high one does not prove good work, but instrument costs show that a professional kit is an investment of hundreds of thousands of reais. Our data cannot say which equipment each provider uses.
Require a report with clear limits: areas examined, procedures, restrictions and findings. See what to require before hiring and our sweep FAQ.

How we did the study
We queried the public search of Brazil's National Public Procurement Portal (PNCP) on Nov 5, 2026. Law 14,133/2021 created the portal for centralized, mandatory disclosure of procurement acts[1].
We used 30 Portuguese terms, such as "varredura eletrônica", "contraespionagem", "TSCM" and "junção não linear", across notices, contracts and price agreements. This returned 1,731 records.
We filtered for related subject matter and read 95 records with their items and values. We manually classified 51 items and excluded false positives: IT vulnerability scanning, metal detectors, monitored alarms, generic counterintelligence courses and technical support.
A notice and contract for the same purchase count once. When a purchase bundles several instruments, each enters its own category at its own value. Medians use each item unit value, not weighted by quantity.
Limitations and conflict of interest
- The data covers public purchases only. It does not measure the price of a private sweep of a home, vehicle or company.
- There are only 3 service engagements, with different scopes. They are not a market average.
- Values are contracted, awarded or registered, not necessarily paid. Price agreements are quantity ceilings.
- PNCP catalog descriptions often do not match the actual object. Classification was therefore manual and may contain errors: every row links to the original.
- Term searches may have missed purchases, and one query failed despite retries (kit contrainteligência (editais)). The selected records start in 2023.
- BlackSweep sells sweep services and has a commercial interest in this topic. The company does not appear as a supplier in any record, and we do not state our own prices here. Supplier names are on PNCP.
