When a company pursues ISO 27001 certification, it often focuses on firewalls, encryption, and access controls. What gets underestimated — sometimes dangerously so — is the human side of information security. The standard is explicit: people are both the greatest asset and the greatest vulnerability in any security framework. That is why background checks on employees are not a nice-to-have under ISO 27001. They are a core requirement.


The question organisations ask most frequently is this: "What are the ISO 27001 requirements for background checks of employees?" In plain terms, what exactly does ISO 27001 require when it comes to screening your people? The answer has real consequences for HR departments, security officers, and compliance teams worldwide.

What ISO 27001 Actually Requires

ISO 27001, the internationally recognised standard for information security management systems (ISMS), includes Annex A Control 6.1, which sspecifically addresses screening. The control requires that background verification checks are carried out on all candidates for employment — and in many cases, on existing employees and contractors — in accordance with applicable laws, regulations, and the sensitivity of the information they will access.


This means screening is not optional once your organisation commits to ISO 27001. The depth and scope of checks must be proportional to risk: the more sensitive the role, the more thorough the verification. Certification auditors will look for documented processes, consistent execution, and evidence that checks are actually being performed — not just policies that exist on paper.


For companies operating across borders — common in industries like finance, IT, critical infrastructure, and energy — this creates a complex challenge. Employment law, privacy regulations, and the availability of official records vary widely from country to country. A screening process that works in Slovakia may not be legally compliant in Brazil or Singapore without significant adaptation.

Why Standard Approaches Fall Short

Many organisations attempt to manage pre-employment screening in-house or through fragmented local providers. The result is inconsistency — different levels of diligence applied to different candidates, gaps in documentation, and compliance exposure that only becomes visible during an audit or an incident.


ISO 27001 does not just ask whether screening happened. It asks whether the process is systematic, proportionate, documented, and auditable. That raises the bar considerably. Manual workflows, spreadsheets, and email-based coordination do not meet that standard.


Add to that the complexity of General Data Protection Regulation (GDPR) compliance in Europe, data protection laws in other regions, and the need to screen not only direct employees but also contractors and external partners — and the picture becomes clear: background screening at scale requires a purpose-built solution.

Validato: Built for Exactly This Challenge

Validato is a global background screening and human risk management company headquartered in Switzerland, operating across more than 200 countries. The platform was designed from the ground up to meet the demands of organisations that take compliance seriously — including ISO 27001 requirements for employee verification.


What sets Validato apart is the combination of automated data collection with human expert assessment. Rather than relying on algorithms alone, Validato’s specialists verify information directly at the source. This Human in the Loop approach delivers results that are not only fast but defensible — exactly what certification auditors and risk officers need.


Validato’s screening services cover the full range of verification needs relevant to ISO 27001:

  1. Pre-employment screening: criminal record checks, identity verification, qualification validation, employment history, etc.
  2. In-employment screening: ongoing integrity checks, re-screening, compliance monitoring, etc.
  3. External employee verification: contractors, auditors, third-party partners, etc.
  4. KYC and AML checks: sanctions lists, PEP status, adverse media, etc.

Crucially, the platform is itself ISO 27001 certified and GDPR-compliant, which matters enormously when you are trying to demonstrate that your own security management meets the highest standards. Using a certified partner strengthens your compliance posture rather than introducing a new risk.

The Global Dimension of Human Risk

ISO 27001 is a global standard, and organisations seeking certification often operate globally. Validato’s reach across more than 200 countries means that whether you are hiring in London, Singapore, Bratislava, or São Paulo, the same rigorous personnel verification process applies. Local legal requirements are factored in automatically, ensuring that your screening programme remains compliant without requiring in-house expertise in every jurisdiction.


This global capability is particularly relevant for sectors that ISO 27001 scrutinises most heavily: financial services, IT and cloud providers, critical infrastructure operators, healthcare, and energy companies. In all of these sectors, the workforce is often international and mobile. Integrity checks must keep pace.

Human Risk Management Goes Beyond the Hire

ISO 27001 increasingly reflects a broader understanding of insider risk. Threats do not only arrive from outside the organisation. Current employees — whether through negligence, coercion, or deliberate intent — represent a significant and growing risk to information security.


Validato’s human risk management consulting service addresses this directly. The team works with organisations to build tailored frameworks for identifying and managing people-related risks across the entire employment lifecycle — from initial screening through to exit. This is not just about ticking boxes for an audit. It is about building a culture of trust and accountability that makes organisations genuinely more secure.

What Auditors Expect to See

When an ISO 27001 auditor reviews your ISMS, they will expect to find documented screening policies, evidence of consistent execution, records of individual checks, and a clear process for handling exceptions. They will also want to see that screening extends to third parties and contractors who access sensitive systems or data.


Validato’s platform provides full transparency across all ongoing and completed validations, with traceable results stored securely for the retention period you define. The audit trail is built in — you are not scrambling to reconstruct records when the auditor arrives.

Compliance is Not the Ceiling — It Is the Floor

Meeting ISO 27001 requirements for background checks is important. But the organisations that take information security most seriously do not treat compliance as the goal — they treat it as a baseline. The real objective is a workforce and partner ecosystem that is genuinely trustworthy, verifiable, and low-risk.


That is what Validato delivers. Through a combination of global reach, technical rigour, expert human oversight, and a platform that makes screening fast and intuitive, Validato helps organisations around the world build the kind of security posture that ISO 27001 is designed to reflect — not just on paper, but in practice.


If your organisation is preparing for ISO 27001 certification or wants to strengthen its existing background screening process, Validato is the partner built for the job.
