Right fit if
Right for cyber consultancies, CHECK and CREST-accredited test houses, MSSPs, and incident response specialists. Particularly strong for SMBs with deep specialist expertise (industrial control systems, cloud security, secure-by-design) where the buyer needs real depth rather than a generalist.
Wrong fit if
Wrong fit if your security offering is bundled inside a wider IT outsource (use Technology Services 3 instead), if you cannot demonstrate accreditation against the relevant scheme (CHECK, CREST, NCSC CCP), or if your only cyber capability is reselling third-party tools.
