Human Resources
Support Services
Security-informed human capital solutions — from workforce risk management and background investigations to security leadership support and sensitive HR situations that require experienced, independent expertise.
People Are Your Greatest Asset —
and Your Greatest Risk
The human element is the most complex variable in any security program. The employee who becomes an insider threat, the key hire whose background was never properly investigated, the termination that wasn't handled with sufficient security planning — these are not hypothetical risks. They are recurring realities across organizations of every size and sector.
GS3 brings its security expertise directly to the human capital function — ensuring your people are properly vetted, your workforce risks are identified and managed, and your sensitive HR situations are handled with the professionalism and safety they require.
We are not an HR firm. We are a security firm with deep experience in the human dimensions of organizational risk — and that distinction is exactly what our HR clients value most.
The Lens HR Firms Don't Have
GS3 evaluates human capital decisions through a security lens — identifying risks that standard HR processes routinely miss and applying investigative tradecraft that no HR generalist possesses.
The Independence You Need
GS3 operates as an independent third party — critical when internal investigations, sensitive terminations, or executive-level reviews require neutrality that internal HR cannot provide.
Connected to GS3's Full Capability
HR support engagements can draw on GS3's full capability — investigations, protective services, threat assessment, and advisory — providing a level of depth no HR-only firm can match.
Four Categories. One Integrated Approach.
Workforce Risk Management
Identifying, assessing, and mitigating the security risks that originate from within your workforce — before they escalate into incidents that affect people, operations, or reputation.
Insider Threat Programs
Design and implementation of insider threat detection programs — behavioral indicator frameworks, reporting protocols, and supervisory training to identify and address internal risks before they materialize into theft, sabotage, or violence.
Workplace Violence Prevention
Threat assessment services for specific individuals, behavioral threat assessment team consultation, threat management plans, and safety protocols for organizations responding to concerning employee behavior or credible threats to the workplace.
Sensitive Termination Support
Security planning and on-site support for high-risk terminations — executives with information security concerns, volatile employees, or individuals with a known history of threatening behavior. GS3 ensures the process is handled safely for all parties involved.
Investigative Services
Independent, professionally conducted investigations that provide HR and legal counsel with the factual findings needed to make defensible employment decisions.
Background Investigations
Comprehensive pre-employment and ongoing screening: criminal history (all jurisdictions), employment and education verification, reference interviews, professional license validation, global watchlist screening, and financial background for roles with fiduciary responsibility.
Executive Vetting & Due Diligence
In-depth background investigations on C-suite candidates, board nominees, investors, and key hires — examining reputational history, financial background, litigation history, regulatory sanctions, and security-relevant associations beyond what standard screening captures.
Workplace Misconduct Investigations
Independent investigation of harassment allegations, hostile work environment claims, theft, fraud, and policy violations — conducted with interviewing discipline, evidentiary rigor, and full documentation to support HR and legal action while protecting the organization's legal position.
Security Leadership & Program Development
Strategic support for organizations building or evolving a security function — from designing the program architecture to recruiting and vetting the right leadership.
Security Director Search & Vetting
Candidate sourcing, background investigation, and competency assessment for corporate Security Director, CSO, and senior security leadership hires — ensuring the individual who leads your security function can actually perform it.
Policy & Procedure Development
Creating or reviewing security policies, codes of conduct, employment standards, and HR security protocols — aligned with current best practices, regulatory requirements, and the specific operational realities of your organization and jurisdictions.
Security Org Design
Structuring the security function for organizations that are building for the first time or redesigning after growth — defining roles, reporting lines, staffing models, vendor relationships, and key performance indicators for the security team.
Operational HR Support
Execution-level support for organizations managing specific personnel challenges, security staffing needs, or workforce events that require GS3-level expertise.
Security Personnel Staffing
Sourcing, vetting, and placing qualified security professionals — protective agents, security managers, investigators, and analysts — for permanent, contract, and project-based engagements. Every candidate is vetted to GS3's standard before presentation.
Security Training Programs
Designing and delivering security training curricula for corporate employees and security personnel — executive safety awareness, travel security, situational awareness, de-escalation, active threat response, and role-specific operational procedures.
Reduction-in-Force & Labor Event Security
Security planning and on-site support for layoffs, workforce reductions, union actions, and organizational restructuring events — ensuring the safety of HR and leadership personnel throughout a potentially volatile workforce event.
