Penetration Testing for Recruitment Agencies in the UK

Penetration testing for recruitment agencies in the UK

Recruitment agencies are among the largest processors of personal data in the UK economy. A mid-sized agency may hold CVs, contact details, employment histories, salary expectations, and references for tens of thousands of candidates — alongside confidential client requirements, fee arrangements, and commercially sensitive hiring plans.

This combination of high-volume personal data processing and commercially sensitive information makes recruitment agencies attractive targets, and their GDPR obligations are correspondingly significant.

Why recruitment agencies face particular risk

The volume and sensitivity of candidate data creates significant liability. Recruitment agencies hold information that candidates share in confidence — employment history, reasons for leaving previous roles, salary expectations, sometimes health information relevant to workplace adjustments. A breach of this data causes direct harm to the individuals affected.

Client data is commercially sensitive. Confidential hiring plans, salary bands, and organisational restructuring information shared with a recruiter would cause competitive harm if disclosed.

Business email compromise targeting recruitment agencies is an established attack vector. Attackers who gain access to recruiter email accounts can intercept candidate communications, redirect payment of invoices, or conduct targeted phishing against clients and candidates who trust the agency's domain.

Ransomware attacks that encrypt candidate databases bring the business to a halt. Unlike many businesses where operations can continue manually for a short period, a recruitment agency without access to its candidate database cannot function.

The GDPR position for recruitment agencies

Recruitment agencies process personal data under the legal basis of legitimate interests or, for sensitive data, explicit consent. The ICO has published specific guidance for the recruitment sector and has investigated agencies following data breaches.

Key GDPR obligations for recruitment agencies include: keeping candidate data only as long as necessary and with consent for longer retention; ensuring candidates can exercise their rights to access, correct, and delete their data; implementing appropriate security measures proportionate to the risk; and reporting breaches involving personal data to the ICO within 72 hours.

The ICO's view is that recruitment agencies should conduct regular security assessments of their systems as part of their GDPR compliance programme.

Common vulnerabilities in recruitment agency systems

Candidate portals where CVs are uploaded and job applications are submitted are a common vulnerability. These portals handle file uploads — a common attack vector — and store significant volumes of personal data.

ATS — applicant tracking system — integrations with third-party platforms may create data flows that are not fully understood or secured.

Email systems without proper authentication records are a significant risk given the reliance on email communication with candidates and clients.

Staff accounts with shared passwords or no two-factor authentication are common in agencies with high staff turnover.
