SST Gloucester TEMPEST test facility
Secure Systems & Technologies (SST)Gloucester
Secure Systems & Technologies (SST) operates a Gloucester TEMPEST test and certification facility within Spectrum Control’s SSIA business. The current NCSC listing assures SST for TEMPEST product testing under the Formal TEMPEST Certification Scheme, CFTCS. The owner also advertises UK-linked development testing and reporting support. The assurance is specific to TEMPEST, without a general EMC accreditation claim.

Key facts
- Exact Gloucester facility
- Brunel Court, Waterwells, Quedgeley, Gloucester GL2 2AL. Owner UK contact and NCSC profile identify this location, while the SST UK brand page describes the purpose-built Gloucester TEMPEST facility.
- Scheme-specific assurance
- NCSC’s current CFTCS page describes an accredited test facility and screen enclosure for TEMPEST product certification. One initial product example and subsequent limited production assurance checks are separate stages.
- Published enquiry
- Owner UK telephone +44 1452 371999 and its contact form. NCSC lists Andy Trapp on +44 1452 557344 and Laurence Beesley on +44 1452 557332. These are source-listed contacts, without independent present-role verification or decoded protected email.
Testing capabilities
CFTCS TEMPEST product examination and testing
NCSC describes products examined against the TEMPEST standard by engineers qualified to CFTCS standards and tested in an NCSC-accredited screen enclosure. The initial CFTCS test is performed on one example of the product. Exact product configuration, scheme requirements and certification costs require agreement.
Limited TEMPEST Production Assurance Testing
The NCSC scheme description requires TPAT after the initial test to check that the build standard is consistent. These limited tests apply to the production run to maintain TEMPEST integrity. They are distinct from the initial product test, without a blanket certification claim for other configurations.
TEMPEST development testing and reporting support
The UK SST page links the owner’s TEMPEST testing service, which advertises confidence testing during development, TEMPEST control/test plans and test reports. Early-stage considerations, problem solving and obsolescence planning are also offered. No guaranteed pass, cost saving or delivery date is inferred.

Access and contact
Use the owner UK telephone +44 1452 371999 or contact form. The current NCSC profile lists Andy Trapp on +44 1452 557344, while its CFTCS page lists Laurence Beesley on +44 1452 557332 and labels him Operations Manager. That role is source-listed and has not been independently verified. Agree product configuration, initial CFTCS or production/development work, reporting, site access, costs and programme.

Standards and accreditation
- Formal TEMPEST Certification Scheme
- The current NCSC CFTCS page states that SST meets the required criteria for TEMPEST product testing and describes NCSC-accredited product certification testing. Assurance is specific to this scheme, with exact configuration and production requirements to confirm.
- Initial test and production assurance
- NCSC describes one initial product example, followed by limited TEMPEST Production Assurance Testing on the production run to check build consistency. These distinct stages do not certify arbitrary variants or establish a general EMC method range.
- Management-system context
- The UK owner page lists ISO 9001, ISO 14001 and ISO 45001 for its secure facility. These are management-system claims, separate from the NCSC TEMPEST testing assurance. No ISO/IEC 17025 or general EMC laboratory accreditation was verified in the checked sources.
What to confirm with the facility
- Confirm the exact product configuration, CFTCS requirements and initial-test versus limited production-assurance stage. Assured TEMPEST testing is separate from general EMC accreditation and other global brand/product standards.
- Confirm the development test, control/test plan and reporting deliverables. The owner’s advertising does not establish a guaranteed pass, cost, response time or delivery date.
- Request the required screen-enclosure and test limits directly. Total secure-facility floor area and management-system certifications do not establish laboratory dimensions, frequency coverage or EMC method capacity.
- Provide the product/configuration, quantities, required scheme or test stage, preparation, handling/access needs, reporting and preferred programme dates.

Sources and review
Reviewed by Arc on 1 October 2026 in Europe/London using six fresh official owner and NCSC captures. The exact Gloucester facility, UK owner enquiry and NCSC CFTCS assurance support three TEMPEST testing/support groups. One initial product example, limited production assurance and development work are separately described. The NCSC-accredited screen enclosure is retained without invented dimensions or performance range. General global EMC wording, total secure-facility floor area and management-system certificates are not transferred into local methods or test accreditation. NCSC-listed Andy Trapp and Laurence Beesley contact routes remain qualified, and protected emails are not decoded. No public page publication/modification date was verified. Original titles, canonicals, date-metadata absence, JSON-LD, bodies, headers and retrieval provenance are preserved. Prior owner bytes are identical. The current NCSC profile differs in raw bytes from the preserved prior capture, and current exact TEMPEST assurance controls the guide. Imported EMC accreditation and postcode coordinates are cleared.

Global specialists in TEMPEST security products and test services | SST | Emcon
Owner identifies SSIA as a Spectrum Control business unit with UK SST and Canadian Emcon brands. Global TEMPEST/EMC personnel and product-scheme wording is not transferred into exact Gloucester EMC methods or blanket accreditation.
Secure Systems & technologies (SST)
UK brand identifies a purpose-built Gloucester TEMPEST design/manufacturing/test/certification facility and links the TEMPEST services page. The total secure-facility floor area is not a test capacity. ISO 9001, ISO 14001 and ISO 45001 are management-system context rather than laboratory method accreditation.
Owner contact identifies SST UK office at Brunel Court, Waterwells, Quedgeley, Gloucester GL2 2AL, telephone and contact form. Canadian office is separate, no form submission or guaranteed response inferred.
Secure Systems & Technologies (SST) | National Cyber Security Centre
NCSC current profile assures SST for TEMPEST product testing under CFTCS and as a TEMPEST vendor, with Gloucester address and listed Andy Trapp telephone. This exact profile does not establish general EMC accreditation. Protected email is not decoded and current job title is not inferred.
Assured to provide TEMPEST product testing (CFTCS) | National Cyber Security Centre
NCSC states SST meets CFTCS criteria and describes product examination/testing in an accredited screen enclosure, one initial product example and subsequent limited production assurance tests. Laurence Beesley is NCSC-listed as Operations Manager with a telephone, without independent verification of a present role. Assurance is confined to the stated TEMPEST scheme.
UK SST brand links this shared TEMPEST service page, advertising development confidence tests, control/test plans, test reports and lifecycle support. No assured pass, fixed cost/turnaround or all global product standards is inferred.
