California Lie Detector provides professional internal investigation support for businesses and legal counsel throughout Northern California, including Chico, Vallejo, Redding, and Yuba City. We specialize in utilizing polygraph and CVSA (Computer Voice Stress Analyzer) technology to resolve high-stakes workplace issues such as embezzlement, intellectual property theft, and corporate fraud. Our services are conducted with strict adherence to the Employee Polygraph Protection Act (EPPA), ensuring your corporate investigation is both legally compliant and forensically sound.
Testing is available in-person at our primary geographic anchors, specifically our Chico/Butte and Vallejo facilities or via remote CVSA sessions for voice-based risk assessment.

When a breach of trust occurs within a Northern California business, whether it involves intellectual property theft in Vallejo or financial embezzlement in Chico, the priority shifts from suspicion to forensic verification. Our corporate fraud services are designed to support internal investigations by providing a structured, objective method for resolving specific economic losses. Unlike broad employee screening, which is restricted by federal law, we focus on targeted investigations where a specific incident has occurred.
By merging traditional investigative techniques with voice-based risk assessment and polygraphy, we help companies in the Redding and Yuba City corridors identify the source of internal leaks and financial discrepancies. This proactive approach does more than just identify a bad actor; it reinforces an ethical workplace culture and provides the necessary documentation for legal or insurance-related actions.
Our protocols are specifically tuned for complex B2B scenarios, including:
Using a combination of statement analysis and physiological monitoring, we provide your legal or HR team with the clarity needed to make informed decisions. We focus on “forensically reliable truth verification” to ensure that your investigation remains professional, discreet, and aligned with California’s strict labor standards.
In high-stakes corporate investigations across Northern California, selecting the right diagnostic tool is critical for a defensible outcome. California Lie Detector utilizes two primary methodologies: the traditional Polygraph and the Computer Voice Stress Analyzer (CVSA). Both are recognized as forensically reliable for private truth verification when administered by a certified examiner.
While these tools provide an advanced layer of forensic analysis, they are not a “magic button” for truth. Instead, they serve as sophisticated data collection points that, when combined with professional statement analysis, help a business owner or legal team in Chico or Redding make informed decisions regarding internal losses.
The following table outlines the technical application of our corporate tools:
| Feature | Polygraph Examination | CVSA (Voice Stress) |
|---|---|---|
| Primary Metric | Multi-channel physiological (GSR, Cardio, Resp) | Frequency modulation in the human voice |
| Location | In-person only | In-person or Remote-ready |
| Best Use Case | Complex embezzlement or legal defense | Initial risk assessment & interviews |
| Standard Rate | Starts at $500 | Starts at $400 per session |
We frame our results as validated for private use. This means the data gathered is intended for internal corporate decision-making, administrative investigations, and civil prep.
Important Disclosure: As with all non‑polygraph technologies, California Evidence Code 351.1 applies. No method guarantees 100% accuracy. Results should be used as one part of a comprehensive internal investigation.
By maintaining this clinical approach, we ensure that businesses from Yuba City to Santa Rosa receive a professional service that prioritizes data integrity over lie detection hype.
Navigating corporate investigations in Northern California requires a strict adherence to federal and state labor laws. The Employee Polygraph Protection Act (EPPA) generally prohibits private employers from using lie detector tests for pre-employment screening or random testing. However, a critical “Limited Exemption” exists for ongoing investigations involving economic loss.
If your business in Chico, Vallejo, or Redding has suffered a specific incident, such as theft, embezzlement, or industrial espionage, you may legally request that employees with “access” and “reasonable suspicion” undergo testing. California Lie Detector ensures your company stays compliant by providing the necessary framework for these investigations.
To maintain legal integrity during a corporate investigation in Yuba City or the surrounding Butte County area, the following conditions must be met:
We provide the documentation support needed to ensure your HR and legal teams are protected. By focusing on forensically reliable truth verification rather than “employee screening,” we help you resolve internal crises without triggering the legal pitfalls associated with improper testing.
Legal Disclaimer: California Lie Detector provides investigative support. We recommend all corporate clients consult with their legal counsel to ensure specific adherence to California Labor Code and EPPA filing requirements before scheduling an examination.
California Lie Detector maintains a strategic physical presence at four primary geographic anchors to support the Northern California business community. By concentrating our expertise in these hubs, we provide consistent, forensic-quality investigation support without the dilution of “pop-up” locations. For corporate matters requiring immediate action, we offer priority scheduling at our Chico and Vallejo offices.
To minimize operational downtime, we provide remote CVSA (Computer Voice Stress Analyzer) sessions. This technology is forensically reliable for private truth verification and allows stakeholders in Santa Rosa or Sacramento to participate in high-fidelity risk assessments without traveling to a physical office. Remote sessions are conducted via secure, encrypted video conferencing, ensuring that voice-frequency modulation data is captured with clinical precision.
Don’t let internal theft or fraud compromise your company’s future. California Lie Detector provides the forensic clarity you need to resolve workplace disputes and protect your bottom line.

A standard in-person polygraph examination for corporate investigations starts at $500. For businesses seeking a voice-based risk assessment tool, a remote CVSA session starts at $400. These rates include the pre-test interview, the examination, and a formal forensic report for your records.
No. Under the Employee Polygraph Protection Act (EPPA), private employers are generally prohibited from using polygraph or CVSA tests for pre-employment screening. Our services are strictly for internal investigation support related to specific incidents of economic loss, such as theft or embezzlement.
Most sessions require 90 to 120 minutes. This timeframe allows our examiners to conduct a thorough pre-test interview, establish a physiological or vocal baseline, and perform the actual truth verification protocols without rushing the subject.
The CVSA is a validated tool for private use and serves as an additional layer of forensic analysis. While it measures different indicators (voice frequency vs. multi-channel body responses), it is highly effective for initial risk assessments. No method, however, guarantees 100% accuracy.
Our primary geographic anchors are in Chico, Vallejo, Redding, and Yuba City. We also offer remote services for businesses in Sacramento or Santa Rosa to ensure timely investigation support across the North Valley and North Bay.
