WinPure Clean & Match

WinPure Clean & Match v11 is an extremely powerful data quality, data cleansing, data matching and entity resolution solution designed to help organisations turn inconsistent, duplicate and fragmented data into accurate, trusted and usable information. The platform provides an integrated environment for profiling, cleaning, standardising, matching, deduplicating and consolidating data, helping organisations improve data quality without having to move sensitive information to external cloud-based processing services. WinPure Clean & Match can be used across customer, business, supplier, patient, citizen, product and other operational datasets where identifying duplicate or related records and creating a reliable view of data is critical. ## Data Profiling & Data Quality Insights WinPure enables users to profile their data before beginning cleansing or matching. Data Quality Insights helps users understand the condition of their datasets through metrics covering areas such as completeness, validity, consistency, patterns, character distributions and statistical values. Insights & Recommendations goes further by analysing profiling results and highlighting potential data quality problems and recommended next actions. This helps teams move from simply measuring data quality to identifying what should be addressed. ## Data Cleaning & Standardisation The CLEAN module provides tools for transforming inconsistent source data into standardised, usable information. Users can build reusable cleaning processes to correct, format, standardise and transform data across large datasets. Capabilities include data transformations, text manipulation, standardisation, regular expressions, data parsing, value replacement and other data cleansing operations. Live Transformation Preview allows users to see the effect of transformations before applying them, helping make data cleansing processes easier to understand and control. ## Data Matching & Deduplication WinPure Clean & Match provides advanced fuzzy and exact data matching capabilities for finding duplicate and related records across one or multiple datasets. Matching can be configured around the characteristics of the data rather than relying on a single matching technique. Users can define which fields should participate in matching, configure matching rules and thresholds, and use different comparison approaches where appropriate. This allows organisations to identify matches even when records contain spelling variations, abbreviations, formatting differences, missing information or other inconsistencies that make conventional exact matching ineffective. Typical examples include identifying records such as: **Acme Technologies Ltd** **ACME Technology Limited** or: **Jonathan Smith** **Jon Smith** as potentially representing the same real-world entity despite differences in the underlying data. ## Flexible Matching Algorithms WinPure supports multiple matching approaches so that different types of information can be compared using techniques appropriate to the characteristics of the data. Rather than treating every field identically, matching configurations can be tailored for information such as names, organisations, addresses, email addresses, telephone numbers and identifiers. This provides greater control over the balance between identifying genuine matches and reducing false positives. ## Match Explainability Understanding why records have been identified as matches is an important part of trusting matching results. WinPure Match Explainability provides visibility into matching decisions, helping users understand which information contributed to a match and how records were evaluated. Users can explore match information at record and group level, making it easier to validate results, investigate questionable matches and explain matching decisions to other stakeholders. ## Entity Resolution with Match AI For more complex entity resolution requirements, WinPure also provides Match AI, powered by Senzing technology. Match AI is designed to identify relationships and entities across datasets where information may be incomplete, inconsistent or distributed across multiple records. This provides an additional entity resolution capability alongside WinPure's configurable rules-based matching engine. ## Master Record Selection Once duplicate records have been identified, organisations frequently need to determine which record should represent the entity. WinPure provides configurable Master Record selection capabilities that allow users to automatically identify the preferred record within a duplicate group. Selection can be based on data completeness or configurable business rules, helping organisations establish consistent survivorship processes rather than manually selecting records. ## Golden Records Matching and identifying duplicates is often only the beginning of the data quality process. WinPure helps organisations progress towards consolidated Golden Records by identifying related records, selecting preferred information and maintaining a consistent identity for the resulting entity. Golden Record Identity provides persistent identification that can help organisations maintain entity continuity as datasets are refreshed or additional records are introduced. This is particularly valuable for master data management, customer data consolidation, migration projects and environments where the same entities appear across multiple operational systems. ## Secure Local Processing WinPure Clean & Match is designed for organisations that want greater control over where their data is processed. Data cleansing, profiling and matching can be performed locally rather than requiring organisations to upload entire datasets to an external SaaS platform. This makes WinPure particularly suitable for organisations handling sensitive, confidential or regulated information, including public sector, healthcare, financial services and enterprise environments. ## Designed for Business and Technical Users WinPure combines sophisticated data quality and matching capabilities with a visual interface. Users can configure profiling, cleansing and matching workflows without needing to develop an entire data quality solution from code. At the same time, configurable matching rules, algorithms, thresholds and data transformations provide the flexibility required for more complex data quality projects. ## Common Use Cases Organisations use WinPure Clean & Match for a wide range of data quality projects, including: * Customer and contact deduplication * CRM data cleansing * Database consolidation * Data migration * Master data management * Entity resolution * Duplicate detection * Customer 360 initiatives * Single customer or citizen views * Golden record creation * Supplier and business matching * Data standardisation * Data profiling and quality assessment * Preparing data for analytics and AI * Improving data before CRM, ERP or other system migrations ## Building Trusted Data Poor-quality data can affect reporting, analytics, CRM adoption, operational processes, regulatory activities and AI initiatives. WinPure Clean & Match brings profiling, cleansing, matching, entity resolution and Golden Record capabilities together to help organisations understand their data, improve its quality and identify the real-world entities represented within it. The result is cleaner, more consistent and more trustworthy data that organisations can use with greater confidence.

Postio

Postio is a suite of UK data validation APIs designed to assist developers in verifying addresses, emails, and phone numbers efficiently. The platform offers three primary services: address lookup, email validation, and phone validation, each tailored to meet the specific needs of applications requiring accurate and up-to-date data. The address lookup API provides comprehensive coverage of the UK's Postcode Address File (PAF), encompassing approximately 30 million addresses. By inputting a postcode, users receive a structured address output, ensuring data accuracy and consistency. This service is synchronized nightly with Royal Mail, guaranteeing that the address data remains current. The email validation API performs multiple checks to ascertain the validity of an email address. It examines the syntax, verifies MX records, conducts SMTP handshakes, and detects disposable email addresses. Additionally, the API offers typo suggestions, such as correcting 'gmial' to 'gmail', enhancing data quality and reducing the likelihood of errors. The phone validation API focuses on UK phone numbers, normalizing them to the E.164 international standard. It identifies the type of line—mobile, landline, VoIP, or non-geographic—and provides information on the original and current carriers. This service also indicates whether a number has been ported and assesses its reachability, offering valuable insights for applications that rely on accurate phone data. Integration with Postio is streamlined through its RESTful API, accompanied by official SDKs for various programming languages, including Node.js, Python, PHP, Ruby, Go, and .NET. For client-side applications, Postio offers a browser SDK that enables UK address autocomplete functionality with minimal setup.

The platform offers 100 free lookups to new users, allowing them to evaluate the services before committing financially. Data security and compliance are central to Postio's operations. The platform is hosted in London, ensuring that address and email data remain within the UK, while phone checks utilize an EU carrier network.
