Why this matters

London buyers pick the local pentest vendor, then re-procure when the report fails review.

  • Local vendors that lack CREST or CERT-In credentials get bounced at procurement on the second deal.

  • Templated reports do not survive UK GDPR, FCA cybersecurity, ISO 27001, PCI DSS, and Cyber Essentials Plus review or first SOC 2.

  • Engagements without re-test inside the audit window cost London security leads a second SOW.
