We deliberately excluded Gartner's mandatory feature categories – risk identification, continuous monitoring, risk response management, and learning and analytics – from the table. These are table stakes for any vendor appearing in the MQ. Including them would add noise without differentiating signal.

The five columns we selected represent dimensions where vendors differ meaningfully in architectural approach, not just feature presence. They are derived from the intersection of Gartner's vendor cautions, customer review pain points, and Knovolo's own architectural decisions.

We define causal reasoning as the ability to propagate a global event through a structured world model – from actor to commodity to supply chain impact – generating competing hypotheses with evidence-weighted plausibility scores, rather than producing a single opaque risk verdict.

Altana receives a partial mark for their graph-based architecture, which provides more legible reasoning than black-box scoring – their knowledge graph covers over 2.8 billion shipments and 500 million companies at facility level. However their scoring methodology is not formally verified in the way Knovolo's Convergent Signal Confirmation framework is. Everstream, Prewave, and Resilinc produce risk scores without publishing a formal causal inference framework. Customer reviews of Exiger and Prewave specifically cite arbitrary or unverifiable plausibility scores as a primary pain point.

We define EU-sovereignty as core infrastructure hosted exclusively within the EU, combined with a customer-side relay architecture ensuring supply chain data never has to leave the customer's environment. No competitor in the table meets this definition.

Everstream explicitly leverages AWS data services for their platform, confirmed via their own published partnership announcements. Resilinc's platform is US-headquartered with no published EU data residency architecture. Altana operates a federated hub-and-spoke model where customer data stays in dedicated spokes – a more privacy-conscious architecture than standard SaaS – but the company is US-headquartered and does not publish EU-sovereign infrastructure commitments. For the UK government contract, Altana operated within isolated government cloud infrastructure, demonstrating flexibility, but this is not their standard commercial offering. Prewave is Austria-based but does not publish a comparable data residency architecture.

The CLOUD Act allows US authorities to compel US-headquartered companies to produce data stored on their infrastructure, regardless of where that data physically resides. This creates structural exposure for EU customers of US-headquartered vendors that no contractual data residency commitment fully eliminates.

We define customisability as the ability for customers to meaningfully configure the product to their specific supply chain topology – not just select from vendor-defined templates. Knovolo provides a drag-and-drop geographic canvas, customer-defined nodes, custom filter logic, and direct access to the STP server via their relay.

Customer reviews of Everstream and Exiger consistently cite rigid UI, rigid workflows, and lack of combined filtering as primary frustrations – including reports of too many clicks between query and result, and missing bulk actions on alerts. Prewave receives a partial mark for their industry pre-configurations and SAP integration, though customers specifically flag limited combined filtering flexibility. Altana's platform is noted in the MQ as requiring comprehensive training and effective change management, with a steep learning curve that limits practical customisability for most users. Resilinc customers flag rigid automated refresh cycles and no plugin support for external tooling.

Altana and Prewave lead on multitier mapping. Altana's proprietary knowledge graph maps over 850 million facilities across more than 500 million companies, with over 125 million facility-to-facility relationships, covering Tier 0 through Tier N. Prewave maps through their SAP Supply Chain Orchestration partnership, enabling N-tier graph integration with network effects across the SAP customer base.

Resilinc maps to part-site and raw material level, five tiers deep, using a hybrid of supplier-validated data and AI-driven autonomous mapping – confirmed by their own platform documentation. Everstream receives a partial mark given their sub-tier visibility capabilities, though the MQ notes ongoing work to improve network completeness.

Knovolo receives a partial mark: customers can define their own supplier nodes with geographic resolution on the canvas, but automated N-tier discovery is not available at GTM. This is an honest gap, and one we expect to close over time.

Prewave is the clear leader on ESG and sustainability risk management. Their platform covers more than 150 risk categories across 400+ languages, includes an AI-powered Carbon 360 emissions module estimating emissions across all supply chain tiers, and integrates with the EU's TRACES certification platform for EUDR compliance. The Gartner MQ notes that Prewave's sustainability experts actively participate in European Commission regulatory bodies and global standards organisations.

Altana, Everstream, and Resilinc offer ESG capabilities as part of broader platforms. Everstream raised their Series B specifically via Morgan Stanley's 1GT platform, which focuses on companies addressing carbon impact – indicating ESG is a meaningful product direction, though without Prewave's regulatory depth. Altana and Resilinc each offer sustainability risk modules without equivalent regulatory alignment.

Knovolo does not offer ESG-specific functionality at GTM. This is an honest gap, not a roadmap item.
