Documentation read on 7 October 2026
The product compared is Open Opportunities (openopps.com) , UK-based global tender search and alert service aggregating government procurement data from more than 1,050 sources.
Bid / no-bid support belongs to Stage B when enabled; your team keeps the decision.
Our verdict · For a defence, security or industrial supplier bidding on public and NATO tenders
Viglia is the more direct choice if you want each notice from its worldwide monitoring, NATO agencies included, qualified against your catalogue, analysed with citations and given a reasoned bid / no-bid recommendation. Open Opportunities keeps the edge for self-serve search across even more countries at a published price, or for raw procurement data through an API.
Choose Viglia if
- your products are specific and a broad search still leaves your team sorting results;
- NSPA and NCIA matter to you as much as BOAMP, TED, SAM.gov or CanadaBuys;
- you want each requirement cited in the tender documents and a reasoned bid / no-bid recommendation;
- you want the setup done with you and the first selections reviewed together.
Keep Open Opportunities if
- you need portals in countries beyond the 60+ that Viglia monitors and prefer to run your own searches, at a published self-serve price (Solo from £120 per user per month, billed yearly);
- you need procurement data inside your own systems through a pay-as-you-go API.
Viglia at work
What Viglia does with a notice, step by step
For activated sources and accessible documents, Viglia relates requirements to your catalogue and links findings to the source document, including the passage when identified. Stage B supplies bid / no-bid support when separately enabled. The fictional example below illustrates the method, not an observed product execution.

Sourced comparison
Open Opportunities and Viglia compared
The Open Opportunities column only restates what the vendor publishes, or an absence bounded to the pages we read. The Viglia column describes the current commercial scope: Stage A by default and Stage B separately enabled when granted; roadmap items are never presented as available.
| Criterion | Open Opportunities · public evidence | Viglia · current scope | What to check before deciding |
|---|---|---|---|
| Model | A procurement intelligence platform that aggregates government tender and contract data into one searchable database, with a per-seat subscription. About Open Opportunities | An operated monitoring and qualification service for public and institutional tenders, specialised in defence, civil security and fire and rescue, with worldwide monitoring. | Decide who should spend the screening time: your team running searches, or a service delivering a reasoned shortlist. |
| Breadth of sources | Open Opportunities lists more than 1,050 procurement portals across more than 180 countries and invites customers to get in touch about portals not shown on its list. Open Opportunities sources | More than 200 official sources in more than 60 countries, across six continents: France, Europe, the United States (SAM.gov and several states), Canada (CanadaBuys, SEAO), Latin America, Africa, Asia, the Middle East, Oceania, plus NATO (NSPA, NCIA), the UN (UNGM), the EU (TED) and the World Bank. | If you need portals in countries Viglia does not monitor, breadth wins. If your key buyers publish on sources both cover, depth and qualification on those sources matter more. |
| French, NATO and UN sources | Its source list includes BOAMP, PLACE (marches-publics.gouv.fr), Achat Public, TED, UNGM and a NATO procurement entry that describes NSPA. Open Opportunities sources | TED, BOAMP, NSPA, NCIA and UNGM are monitored in a single work queue with a link to each original notice, alongside more than 200 official sources in more than 60 countries. | The source lists overlap. Compare what happens after collection: how notices are ranked, explained and checked against what you actually sell. |
| How relevance is decided | Open Opportunities says activity search lets you describe what you do in your own words and finds tenders for that work, including ones your keywords would never match, in any language. When Open Opportunities isn’t right for you | Matching against your product catalogue: each lot is compared with your products, capabilities and exclusions, and the shortlist explains each match. | Bring the same description of your offer to both and compare the first twenty results, including what each one wrongly kept. |
| Tender documents | Open Opportunities scans notices for tender documents to attach, adds scored CPV codes and links duplicate notices into one record. Open Opportunities home page | Tender-document analysis with requirements, dates and clauses cited to the source document, an exportable compliance matrix and OCR with uncertain passages flagged. | Decide whether you need clean records and attachments, or an analysis of what each tender asks of you. |
| Pricing and trial | Solo at £120 per user per month and Team at £259 per team per month on annual billing, a 30-day money-back guarantee on annual plans, and API credit from £100. Open Opportunities pricing | Pricing on request, set by the sources and the scope operated for you. | A self-serve licence and an operated service are priced differently.

Finding a tender and qualifying it are two separate jobs
Open Opportunities says plainly that nobody’s first page is all relevant: in its test, about 3 in 10 results in its top ten on Find a Tender were worth opening.
Viglia’s work starts after collection: a daily review, an explained shortlist and a bid or no-bid recommendation with reasons. The decision stays with your team.
Measure both steps separately. Count the relevant notices each option finds, then count the minutes your team needs to reach a bid decision on each.
Use the published evidence, then test your own trade
Open Opportunities publishes per-portal results and invites prospects to bring their own searches to a side-by-side comparison.
Viglia’s explainability works per notice: each score and each summary cites its sources, and source health, alignment checks and completeness audits track reliability.
A vendor benchmark tells you how a tool performs on the vendor’s searches. Repeat the exercise with twenty notices from your own market, including corrigenda and multi-lot tenders.
Defence buyers: a source listing is a starting point
Open Opportunities says security-cleared contractors and defence suppliers use it for MOD, NATO and allied nation opportunities.
Its NATO procurement source page describes NSPA and says the source is monitored daily, with alerts by email.
Defence, civil security and fire and rescue are Viglia’s specialisation, with NSPA and NCIA among its named sources and every notice matched against your catalogue and exclusions.
Ask each provider for last month’s NSPA and NCIA notices in your categories, then check them against the agencies’ own portals.
When to keep Open Opportunities
Open Opportunities publishes a page on when its service is not the right choice, for example if you sell to a very small market or do not mind missing opportunities.
Official source: When Open Opportunities isn’t right for you
It also sells an API with structured JSON output, data enriched with countries and categories, and pay-as-you-go pricing per call and per record, for teams that want procurement data inside their own systems.
Viglia is an operated service on more than 200 official sources in more than 60 countries; it does not cover every portal in every country and does not write the response. For self-serve searches across the 180+ countries it lists, Open Opportunities is the natural fit.
Some teams combine both: a broad search tool for countries Viglia does not monitor and an operated service for the markets that drive most of their revenue. Check that the two do not duplicate alerts on the same sources.

FAQ
Do Open Opportunities and Viglia cover the same sources?
Partly. Open Opportunities lists BOAMP, TED, UNGM and a NATO procurement source among more than 1,050 portals. Viglia monitors more than 200 official sources in more than 60 countries, including TED, BOAMP, SAM.gov, NSPA, NCIA and UNGM. The overlap is real; the difference is the qualification layer.

When you need portals in countries beyond the 60+ that Viglia monitors, want to run and tune searches yourself, need an API or prefer a published self-serve price.
Does Viglia publish a recall figure like Open Opportunities?
No. Viglia’s explainability works notice by notice, with each score and summary citing its sources. Test both on the same set of known notices from your market and compare the results yourself.
