Sabotage/industrial espionage

Are procedures or production processes in your company being sabotaged? Do you have a suspicion that your employees are "serving two masters"? Is your business a victim of bugging by the competition? We not only provide you with evidence and seek out perpetrators, but we also implement preventive measures, in order to protect you from further attacks.

Security checks

Do you doubt the integrity of existing employees? Do the statements made in job application materials of prospective employees strike you as false or exaggerated? Is an applicant concealing important facts from you? Do you want to know more about prospective employees than you can ask in all good conscience during the presentation interview? We find answers to your questions.
