NCC Group vs Aristi

Side-by-side comparison of NCC Group and Aristi for penetration testing services. Compare their services, accreditations, compliance expertise, and pricing.

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 Aristi holds Cyber Essentials. From a delivery standpoint, NCC Group operates globally from Manchester, while Aristi operates at a national level out of Birmingham. This matters for on-site testing, time zone alignment, and regional regulatory knowledge. There's a meaningful size gap: NCC Group (500+ team) brings deeper bench strength and capacity for concurrent engagements, while Aristi (11-50 team) offers the smaller firm advantage of senior-led engagements and direct access to principal consultants.
