SLI Compliance

SLI Compliance is an American laboratory that tests and evaluates voting systems for compliance with applicable standards and certification requirements. The organization was founded in 1997 in Wheat Ridge, Colorado, and operates as a division of Gaming Laboratories International (GLI), a testing and assurance company established in 1989 and headquartered in New Jersey. GLI is known primarily for evaluating gaming equipment and related technologies, while SLI Compliance serves the election-technology sector. The laboratory became accredited by the United States Election Assistance Commission (EAC) in 2007. EAC accreditation is significant because it permits an independent testing laboratory to assess voting-system technologies under the federal certification framework used in the United States. SLI Compliance has therefore occupied a specialized role between election-technology suppliers, testing standards, and federal certification authorities rather than functioning as a consumer-facing hardware or software brand. By 2021, SLI Compliance and Pro V&V were identified as the only two organizations authorized by the EAC to certify voting systems in the United States. SLI's EAC certification authorization expired in January 2021. The EAC stated that the laboratory remained in good standing and attributed the delay in re-accreditation to the COVID-19 pandemic and resource constraints. SLI Compliance was re-certified the following month, allowing it to continue participating in the federal voting-system certification process. The available public record provides limited information about SLI Compliance's internal leadership, productized service lines, financial performance, and geographic operations beyond its United States election-testing role. Its principal offering is laboratory testing and certification support for voting systems, rather than the manufacture or retail sale of election equipment. The organization remains associated with GLI, whose broader business covers testing and validation services in regulated technology markets. In July 2025, it was reported that CVC Capital Partners was preparing to acquire GLI. That proposed transaction is relevant to SLI Compliance because the laboratory is part of GLI's corporate structure, although the available reference material does not establish whether the transaction was completed or what operational changes, if any, would affect SLI Compliance.

SLI Compliance was founded in 1997 in Wheat Ridge, Colorado, as a laboratory focused on testing voting systems. Its work developed within the regulated United States election-technology environment, where voting-system manufacturers and election administrators require independent testing against formal standards and certification requirements. The organization later became a division of Gaming Laboratories International, commonly known as GLI. GLI was founded in 1989 and is based in New Jersey. Although GLI's principal historical focus has been testing and validating gambling equipment, its corporate structure has included specialized testing activities in other regulated technology fields. SLI Compliance represents GLI's voting-system testing operation. A significant institutional milestone occurred in 2007, when SLI Compliance received accreditation from the United States Election Assistance Commission. EAC accreditation enabled the laboratory to participate in the federal voting-system certification system. In practical terms, the laboratory's role is to test voting technologies and provide the technical assessment used in the certification process; it is not primarily a manufacturer, retailer, or election administrator. By 2021, SLI Compliance and Pro V&V were described as the two organizations authorized by the EAC to certify voting systems in the United States. SLI's accreditation expired in January 2021. The EAC nevertheless stated that the laboratory was in good standing and explained that re-accreditation had been delayed by the COVID-19 pandemic and resource limitations. The laboratory regained certification the next month. The publicly available information does not provide a detailed account of changes to SLI Compliance's ownership, leadership, laboratory locations, service catalog, or customer base after its re-certification. In July 2025, CVC Capital Partners was reported to be preparing to acquire GLI. Because SLI Compliance is a GLI division, the proposed transaction could affect its corporate ownership, but the available source does not establish that the acquisition was completed or describe any resulting changes to SLI Compliance.
