London businesses are attractive targets: law firms holding completion funds, accountants with clients' tax records, clinics with patient notes, ecommerce stores with customer accounts. A security audit of your website and applications finds weaknesses before an attacker does and gives you a prioritised list of fixes you can act on.
Typical scope includes authentication and session handling, access control, input validation, dependency vulnerabilities, server configuration, secrets management, backups and logging. UK GDPR requires appropriate technical and organisational measures, and the ICO has fined organisations for failing to apply basic security. Cyber Essentials, the government backed scheme, is required for some public sector contracts and is a sensible baseline for many firms. Payment handling must meet PCI DSS through your provider. Professional bodies like the SRA publish their own warnings about cyber fraud, especially payment diversion scams.
Cost scales with the number of applications, their complexity, whether testing is black box or with source code, and retesting after fixes. Ask an auditor exactly what is in scope, whether they test with permission in production or a copy, how findings are rated, whether a retest is included, and what the report will look like for non technical directors. Frenchy Digital reviews web applications and will refer you to a CREST accredited tester where formal penetration testing is required.
