Organisations place significant trust in their employees, contractors and trusted third parties. Security vetting and employment screening help organisations make informed recruitment decisions, yet many assume that once an individual has successfully passed the recruitment process, the risks have been addressed.
Security vetting provides a point-in-time assessment. People, circumstances and risks evolve throughout employment, meaning trust should be continually supported by good governance, effective oversight and proportionate personnel security measures.
For organisations operating in regulated industries, critical infrastructure, financial services and other high-risk environments, understanding how trust can change over time is becoming increasingly important.
Security Vetting Is the Beginning, Not the End
Pre-employment screening plays a vital role in helping organisations make informed recruitment decisions. Identity verification, employment history, qualifications, criminal record checks and financial screening all provide valuable information about an individual’s suitability for a role.
However, these checks reflect a person’s circumstances at the time they are completed. They cannot predict future behaviour or identify risks that may emerge months or years later.
Security vetting should therefore be viewed as one component of a broader personnel security strategy rather than a one-off compliance exercise.
Risk Can Change During Employment
Employees and contractors may experience significant changes during their careers that alter their exposure to risk.
Examples may include:
- Financial pressures
- Changes in personal circumstances
- Increased access to sensitive information
- New overseas travel or foreign contacts
- Changes in responsibilities or privileges
- Workplace grievances
- Exposure to coercion or exploitation
Most individuals remain trusted members of an organisation throughout their careers. However, recognising that circumstances can change allows organisations to identify emerging risks before they develop into more serious issues.
Change of Circumstances Can Reveal New Risks
Changes in personal circumstances do not automatically indicate wrongdoing, but they can create new vulnerabilities that organisations should be aware of, particularly where individuals hold positions of trust or have access to sensitive information, systems or critical operations.
Michael Handley, Managing Director of Security Vetting at GSA Global, said:
“We have recently supported two organisations where employees had successfully completed their initial security vetting and had become trusted members of staff. Sometime later, changes in their personal circumstances prompted a further review through an agreed change-of-circumstances vetting process. As part of the review, financial probity checks identified significant online gambling activity that had developed during their employment but had not been present when they were originally vetted.”
“The concern was not simply the financial implications. In both cases, the individuals were undertaking safety-critical roles, and evidence suggested that gambling activity had taken place during working hours. This created wider concerns around distraction, judgement and potential vulnerability. Importantly, the outcome was not punitive. By identifying the issue early, the organisation was able to support the individuals, reduce the associated risks and avoid the loss of two experienced members of staff.”
This example illustrates an important point. Security vetting is not about assuming people will become a risk. It is about recognising that circumstances can change and ensuring organisations have the correct processes in place to identify emerging concerns, protect their people and safeguard the organisation.
A structured change-of-circumstances process allows organisations to respond appropriately when new risks emerge, while balancing security, employee welfare and operational resilience.
Personnel Security Is About More Than Screening
Strong personnel security combines recruitment screening with clear governance, effective management and an organisational culture that encourages concerns to be raised appropriately.
This may include:
- Proportionate re-screening
- Insider risk awareness
- Whistleblowing arrangements
- Manager awareness and training
- Access reviews
- Ongoing due diligence for sensitive roles
- Clear reporting procedures
Rather than creating unnecessary barriers, these measures help organisations maintain trust while reducing opportunities for fraud, data theft, corruption and other forms of insider harm.
Insider Risk Often Develops Gradually
Many insider incidents do not occur without warning.
Changes in behaviour, unusual access patterns, conflicts of interest, attempts to bypass established processes or unexplained financial pressures may all warrant further consideration.
An effective insider risk programme does not assume guilt. Instead, it enables organisations to identify concerns early, investigate them proportionately and provide support where appropriate.
Security Vetting Supports Better Decision-Making
Security vetting should never be viewed as a guarantee that future risks will not arise.
Instead, it provides decision-makers with reliable information that supports proportionate recruitment and access decisions. Combined with ongoing governance, personnel security and independent investigations where necessary, organisations are better equipped to manage evolving risks throughout employment.
Michael Handley, Managing Director of Security Vetting at GSA Global, who has more than 40 years’ experience across British policing, corporate investigations and bespoke employee vetting, commented:
“Security vetting is about helping organisations make informed decisions based on the information available at a particular point in time. Trust should never be assumed to be permanent. People’s circumstances, responsibilities and access to sensitive information change over time. By combining effective vetting with ongoing personnel security, organisations are better equipped to identify emerging risks, protect sensitive information and maintain confidence in their people over the long term.”
Mike served for 22 years in British policing, specialising in major crime, fraud investigations, protection duties and intelligence-led operations, before establishing MHG Corporate Risks in 2004. Over the past two decades, he has helped organisations across the UK and internationally strengthen their personnel security through bespoke employee vetting, due diligence and risk management programmes. Today, he leads GSA Global’s Security Vetting division, supporting organisations in protecting their people, information and reputation.
