Cyber Security for UK HR Consultancies and Recruiters
Why HR and recruitment businesses hold some of the most sensitive data there is — and what to do about it.
The data HR businesses hold
HR consultancies and recruitment agencies handle some of the most sensitive personal data in existence. CVs, employment histories, salary details, references, DBS checks, medical information disclosed during hiring, performance management records, disciplinary files, redundancy data — all of it is highly personal and highly protected under UK GDPR.
Recruiters also hold client business information — headcount plans, salary structures, strategic hiring intentions — that clients expect to be treated as strictly confidential. A breach that exposes this information damages client relationships and can destroy a firm's reputation.
Why this sector is particularly exposed
HR and recruitment businesses receive unsolicited emails and documents from strangers as a matter of course — CVs, covering letters, application forms. This makes phishing significantly harder to defend against, because staff are trained to open documents from people they don't know.
A malicious document disguised as a CV can install malware silently when opened. This is one of the most common attack vectors specifically targeting recruitment businesses.
Regulatory requirements
UK GDPR
You are likely both a data controller (for candidate data you collect) and a data processor (for employee data you handle on behalf of clients). Both roles carry significant obligations. Candidate data must only be retained as long as necessary and must be stored securely.
Special category data
If you handle health data, criminal records (DBS), or information about trade union membership during recruitment, this is special category data requiring additional protections.
ICO enforcement
The ICO has fined several recruitment businesses for poor data handling — particularly around retaining candidate data for too long, sharing it without authority, and failing to secure it properly.
Client contractual obligations
Most client contracts will include data protection clauses requiring you to implement appropriate security measures. A breach could expose you to contractual liability as well as regulatory action.
Priority actions for HR and recruitment businesses
Enable MFA on all systems
Email, your ATS or HR platform, and any cloud storage. Essential given the volume of external communication.
Protect against malicious documents
Ensure Microsoft Defender or equivalent is active and scanning email attachments. Consider opening CVs in a protected view before enabling editing.
Strict access controls on candidate data
Candidate records should only be accessible to the consultants working on relevant assignments. Not all staff should have access to all records.
Data retention policy
Many HR and recruitment businesses retain candidate data far longer than necessary. A clear policy — and the systems to enforce it — reduces your GDPR exposure significantly.
Secure data sharing with clients
Stop sending candidate data as unencrypted email attachments. Use a secure portal or at minimum password-protect sensitive documents.
Staff training on CV-based attacks
Brief all consultants on the risk of malicious documents disguised as CVs. Know the warning signs and what to do if something looks suspicious.
