Side-by-side comparison of NCC Group and Dionach for penetration testing services. Compare their services, accreditations, compliance expertise, pricing, and overall scores.
NCC Group leads in our overall scoring, primarily on the strength of industry accreditations and team research and activity. That said, scores don't tell the full story — the right provider depends on your specific testing scope and compliance requirements. Both hold CREST accreditation, but their credentials diverge beyond that — NCC Group additionally carries CBEST and SOC 2, while Dionach holds STAR. Both operate at a global level but from different home bases — NCC Group in Manchester and Dionach in Oxford — which can affect response times and familiarity with local regulatory environments. There's a meaningful size gap: NCC Group (500+ team) brings deeper bench strength and capacity for concurrent engagements, while Dionach (51-200 team) offers the smaller firm advantage of senior-led engagements and direct access to principal consultants.
