Crossbow Enterprise Cybersecurity

Crossbow Enterprise Cybersecurity is a CREST-accredited security and compliance firm that helps regulated businesses achieve and maintain compliance without the overhead of a large consultancy. Crossbow is a PCI Qualified Security Assessor (QSA) and Approved Scanning Vendor (ASV), and a member of the PCI SSC GEAR Committee, contributing to the standards it assesses against rather than only applying them.Our work spans penetration testing across network, web, and application layers; PCI DSS v4.0.1 assessments and SAQ validation; quarterly ASV scanning; and advisory across GDPR and DORA. Every engagement is led by senior, certified assessors, with clear reporting and prioritised remediation guidance built for teams that need to move fast.Crossbow serves [mid-market and growth-stage / enterprise and multi-entity] organisations in payments, fintech, e-commerce, and SaaS that need enterprise-grade rigour with direct access to the people doing the work. For organisations balancing PCI DSS alongside SOC 2, ISO 27001, GDPR, or DORA, we run coordinated assessment and testing that cuts duplicated effort across frameworks.
