Surveillance Investigation Services We Offer
Covert Surveillance Investigations
Think of it as a quiet watchtower. Our covert surveillance services are designed to gather information without raising eyebrows. Whether it’s a cheating partner, suspected employee theft, or suspicious activity, our seasoned investigators observe, record, and report with absolute discretion. No drama, no trace—just facts.
Undercover Operations
Sometimes, the truth hides behind closed doors and guarded conversations. Our undercover agents are trained to blend in, adapt fast, and dig deep. Posing as insiders, they infiltrate environments where open investigation won’t work—be it a fraud ring, illicit business operation, or internal misconduct. It’s gutsy work, but our team is built for it.
Mobile Surveillance Operations
People don’t sit still—and neither do we. Our mobile surveillance experts follow targets across cities, traffic, and unpredictable routes. With fast reflexes and stealthy strategy, we document every move without being noticed. Whether on foot or on wheels, we stay close, yet invisible.
Corporate Security & Fraud Detection
In the business world, one bad move can cost millions—or a reputation. From monitoring employee behavior to exposing white-collar crime, Eye Witness helps companies stay clean, compliant, and secure. We detect fraud, prevent data leaks, and ensure that the people behind your brand are exactly who they say they are.
Electronic Surveillance Methods
Digital footprints tell powerful stories. Using cutting-edge tech, we monitor communications—texts, emails, calls—with full legal compliance. Whether you’re combating cybercrime, uncovering harassment, or preventing data breaches, our electronic surveillance gives you the upper hand in a wired world.
Personal Protection & Stalking Cases
Sometimes, surveillance saves lives. In stalking cases or threats against individuals, our team provides a shield through smart observation and swift response. We track suspicious behavior, monitor threats, and offer real-time intelligence to keep you—and your loved ones—out of harm’s way.
Are you about to take the plunge into marital bliss, but something doesn't feel quite right?
