Penetration testing day rates

Published G-Cloud 15 penetration-testing rates, checked in November 2026. Only suppliers whose listings mention CREST and publish a comparable role rate are included. Prices were published for public-sector buyers and may not reflect comparable scopes. One supplier per row; where several rates exist, a range is shown. Click headings to sort. This site does not favour any supplier.

Organisation size is the employee band stated on the matched CREST profile; membership is the duration displayed on 4 November 2026. Group or brand scope can differ from the contracting entity. Unknown means not verified, not a non-member. Filters combine both selections; Unknown / unverified is available separately. Size ranges follow the published employee-band boundaries, with no split bands or estimated headcounts.

Rates are supplier-published cyber security testing role rates, not fixed penetration-test quotations. Rate ranges combine separate listings and may reflect different scopes. CREST and CHECK mentions in supplier listings are not independently verified credentials. See the linked CREST profiles and entity-scope notes for membership evidence.

Sources and disclaimer

Information is compiled from publicly available G-Cloud 15 service listings and pricing documents checked in November 2026. Supplier names link to an official website where identified, otherwise to their G-Cloud listing. G-Cloud listings, available pricing documents and matched CREST membership profiles are linked separately. CREST profile employee bands and membership durations were captured on 4 November 2026 and are supplier-submitted profile information, not independently audited headcounts. Related-entity profiles are labelled and their values are not attributed to the supplier. Hover over a size or membership value for profile identity and matching notes. Suppliers are initially sorted by CREST membership duration, longest first. Ties are alphabetical; unknown durations appear last. Readers can change the sort using the column headings. There are no paid placements, endorsements or preferential rankings.

This website is provided for general information only, without warranty as to accuracy, completeness or currency. Supplier accreditations, personnel clearance, pricing and availability have not been independently verified. Absence of a mention is not evidence that a supplier lacks a qualification. Rates may exclude VAT, vary by scope and differ from current commercial quotations. Verify all details directly with suppliers before procurement or security decisions.
