Refers to the extent to which information used in the hiring process provides reliable, authentic, and meaningful evidence about a job candidate, employer, or employment opportunity. High-quality signals increase confidence that information (e.g., a person’s identity, skills, credentials, work experience, assessments, references, or an employer’s identity and job posting) is accurate and can be trusted in making employment-related decisions.
Artificial intelligence and digital hiring platforms are making it easier to generate résumés, applications, profiles, credentials, job postings, and interview responses at scale, including “fraudulent” applications. In this context, traditional hiring signals may become less reliable indicators of a candidate’s qualifications or organizational legitimacy. Therefore, employers and hiring platforms are increasingly supplementing “traditional” signals with verification and risk indicators such as identity verification, credential verification, device and network information, location consistency, behavioral patterns, digital identity history, and fraud detection. Many of the verification measures are being implemented at the front end of the hiring process, not at the backend when employers traditionally conducted reference checks and credential verification.
It is increasingly critical to implement signal quality in the hiring process early in the process. Signal quality does not necessarily measure whether a candidate is qualified for a job. It addresses whether the information and evidence used to evaluate the candidate, employer and opportunity are sufficiently authentic, reliable, and trustworthy to support a hiring decision.
There is now an increasingly used category of “hiring technology” emerging around candidate identity, hiring fraud detection, and workforce verification. Several companies illustrate different parts of this emerging market:
- Greenhouse offers Real Talent, a suite specifically described as helping organizations reduce fraud, improve “signal quality,” and build trust across the hiring pipeline. This is especially significant because Greenhouse is a major applicant tracking/hiring platform, suggesting the concept is moving into mainstream recruiting infrastructure.
- Socure launched a Workforce Verification solution in 2025. Its approach evaluates identity, contact, device, behavioral, résumé, and other signals to identify potentially fraudulent applicants. It can apply different levels of verification depending on perceived risk rather than subjecting every applicant to exactly the same process. Socure distinguishes this from a traditional background check: a background check verifies information about someone, while workforce verification seeks to establish that the person behind that information is authentic.
- Crosschg offers candidate fraud detection and identity verification, including government-ID and biometric checks, device/IP fingerprinting, résumé analysis, deepfake detection, and reference validation. Its ApplicantX offering, launched in 2025, is positioned as an end-to-end hiring-fraud defense platform.
- TurboCheck focuses specifically on applicant fraud detection for recruiters. Its tools examine digital identity and contact information and can flag suspicious résumé, profile, email, phone, and identity patterns before candidates progress further in hiring. Its website identifies customers including staffing and recruiting organizations, providing evidence that these tools are being deployed in actual hiring environments.
It should be noted, not every digital signal is inherently fair or appropriate for employment decisions. Location, device reputation, behavioral patterns, and digital-history data can create privacy, discrimination, accessibility, and false-positive/negative concerns. A candidate traveling internationally, using a VPN, sharing a device, having a thin digital footprint, or changing locations could appear “unusual” without being fraudulent. These systems can raise important questions about what signals should be collected, how they are weighted, whether candidates can challenge errors, and whether a low confidence score becomes an automated barrier to employment.
