How the two are positioned
Both are outside-in. The comparison is about what a finding is worth when you have to defend it, and how much of the model you are allowed to see.
Side by side
| Dimension | PuReAI | SecurityScorecard |
|---|---|---|
| Score format | 0-100 numeric score with the four weighted segments shown separately. | A-F letter grade mapped from a 0-100 score across ten factor groups. |
| Model visibility | Weights published; each finding contributes once, in one segment. | Factor groups and signal categories documented; the size-normalisation and calibration steps are described conceptually, not as an exact published formula. |
| Evidence per finding | Raw artefact attached: DNS record, certificate, banner, commit or document. | Issue-level evidence and signal detail available inside the platform per factor. |
| Regulatory mapping | Dedicated DORA, NIS2, ISO 27001, NIST CSF, PCI DSS and TIBER-EU mappings. | Compliance reporting features referencing common frameworks are part of the platform. |
| Deployment | Cloud or sovereign/on-premise, including air-gapped. | Vendor-hosted SaaS platform delivered through SecurityScorecard's cloud. |
| False positive handling | Confidence level on every finding; version-inferred vulnerabilities labelled as inferred. | Dispute and remediation workflow available for factor-level findings. |
| Score cadence | Continuous, with score history showing degradation between reviews. | Continuously refreshed scoring described as built on real-time intelligence. |
| Data volume claim | Focused, per-domain OSINT across twelve modules. | Vendor states its engine analyses billions of data points across a borderless digital footprint. |
| Primary buyer motion | Free domain report, then a scoped engagement. | Free security rating, then enterprise subscription. |

A closer look
Overview
PuReAI
PuReAI takes a numeric-first approach: a single 0-100 Company Risk Score built from four published, weighted segments, with every contributing finding traceable back to a specific artefact. It is designed for teams who need to explain a movement in score, not just report it, whether that explanation goes to an internal risk committee, an auditor, or a supplier disputing their rating. The platform treats regulatory reporting as a first-class feature rather than an add-on, with dedicated mappings to frameworks used by EU financial and critical-infrastructure regulation. Deployment can be entirely inside the customer's own infrastructure when jurisdictional or sovereignty requirements apply, without changing the scoring methodology used.
SecurityScorecard
SecurityScorecard is a well-known ratings platform that expresses cybersecurity posture as a letter grade from A to F, mapped from an underlying 0-100 score, across ten factor groups covering areas like network security, DNS health, patching cadence, and application security. Its public methodology materials describe a signal collection and attribution pipeline, size normalisation to make scores comparable across organisations of different sizes, and a calibration process feeding into the scoring engine, branded as TITAN AI on its current site. SecurityScorecard positions itself around a very large data collection footprint and real-time refresh, aimed at both internal security posture management and third-party risk monitoring at scale.
Deployment options
PuReAI
PuReAI is available as a managed cloud service or as an on-premise, customer-hosted deployment, including a fully air-gapped configuration with no external network dependency. Organisations in regulated sectors, or those with strict data residency or sovereignty requirements, can run the same scoring engine and published weighting entirely inside their own environment. This is a deployment choice, not a different product tier: the methodology, segment weights and evidence model are identical whether the platform runs in PuReAI's cloud or the customer's own infrastructure.
SecurityScorecard
SecurityScorecard's public site and documentation describe a cloud-based, vendor-hosted SaaS platform accessed through its web portal and API. There is no publicly documented option for customers to deploy the SecurityScorecard scoring engine inside their own on-premise or air-gapped environment; the product is consumed as a hosted service, which is standard for ratings platforms of this type but does not accommodate customers whose procurement rules require the workload itself to reside on their own infrastructure.
Scoring transparency
PuReAI
The scoring formula behind PuReAI's Company Risk Score is published outright: Compromises at 0.4, Issues at 0.3, Supply Chain at 0.2 and Exposure at 0.1. Each finding is attributed to a single segment, so a change in score can be traced to the exact category and evidence that caused it. This is intentionally simpler and more literal than a multi-factor model with internal calibration steps: the goal is that a supplier, a regulator or an internal reviewer can recompute the logic behind a number without needing PuReAI to explain it to them.
SecurityScorecard
SecurityScorecard documents its scoring approach in materials such as its public 'Deep Dive in Scoring Methodology' guide, describing ten factor categories, a signal processing workflow, an attribution engine, size normalisation and a calibration process before scores are finalised into the 0-100 range and mapped to a letter grade. This is more detail than many competitors publish, and SecurityScorecard also documents its ten risk factors individually. The precise mathematical weighting used inside the scoring engine to combine signals into a factor score, however, is described narratively rather than published as an exact formula customers can independently recompute.
Data collection
PuReAI
Collection is passive, external and artefact-preserving: every finding retains the underlying DNS record, certificate, banner, exposed commit or document that produced it, and inferred findings (such as a vulnerability inferred from a software version string) are explicitly labelled as inferred rather than confirmed. No credentials or supplier cooperation are required, and a confidence level is attached to each finding so reviewers can weigh evidence quality directly.
SecurityScorecard
SecurityScorecard collects signals across ten factor categories from internet-wide scanning, threat intelligence feeds, and its own sensor and honeypot infrastructure, describing this on its site as non-intrusive, outside-in measurement covering an organisation's public digital footprint. The company states its engine processes very large volumes of data points to build a real-time view of an organisation's posture, with an attribution engine responsible for mapping observed infrastructure back to the correct organisation.
Coverage
PuReAI
PuReAI focuses on depth per domain: twelve OSINT modules run against each scored entity, including supply-chain discovery to surface dependencies the customer had not declared, aimed at portfolios where each supplier relationship warrants detailed review rather than a broad, shallow scan across thousands of unrelated companies.
SecurityScorecard
SecurityScorecard emphasises breadth, describing coverage across a very large and borderless set of organisations with continuous monitoring, which supports use cases like scoring an entire vendor portfolio quickly or benchmarking against industry peers without waiting for individual onboarding.
Integrations
PuReAI
Findings and score changes route into common workflow tools including Splunk, Sentinel, Jira, ServiceNow and Slack, plus a webhook and REST API, available consistently whether PuReAI runs in the cloud or on-premise.
SecurityScorecard
SecurityScorecard publishes integrations with common GRC, ticketing and SIEM tools through its marketplace and API documentation, consumed against its cloud-hosted platform since there is no customer-hosted deployment option.
Pricing model
PuReAI
A free domain report is available to start, with paid engagements scoped by number of monitored domains and suppliers, and by deployment mode (cloud or on-premise). No fixed public price list is published, since scope varies by portfolio.
SecurityScorecard
SecurityScorecard offers a free security rating as an entry point, with paid tiers and enterprise subscriptions for ongoing monitoring, vendor risk management and additional modules; SecurityScorecard does not publish a fixed public price list on its site.
Support
PuReAI
Analyst-reviewed disputes with a fixed five-business-day resolution window are available on every finding, alongside standard account and technical support channels.
SecurityScorecard
SecurityScorecard documents a dispute and remediation workflow for factor-level findings, along with a support help centre and knowledge base covering platform usage and scoring questions.

Questions we get asked
Why a number rather than a letter grade?
A letter grade hides the distance between two suppliers in the same band. The four segments are shown separately so you can see whether risk comes from an active compromise or from surface size.
Does PuReAI score our suppliers automatically?
Yes - identified vendors and dependencies are scored continuously, with the same published formula used for your own domain.
Can SecurityScorecard be run on-premise?
SecurityScorecard's own documentation describes it as a cloud-hosted platform; it does not publish an on-premise deployment option.
