Vores kunder siger

Danny's security company performed the security and alarm service in the Jeudan Group both at the headquarters and a large number of selected properties. I have always experienced Danny and his people as loyal and punctual. There was never any doubt about Danny, he did a really good job and was due to his good efforts known and respected with his company. I can only give Danny the best recommandation along the way.
Frank Ewert
Direktør & partner at Executive Cognito A/S
I used Danny's company for a total security solution, including fencing, when our vessel - Pacific Orca - called at the port of Copenhagen for a naming ceremony. Danny handled all of the safety parameters very well. His staff were timely , professional and polite. On top of that Danny responded quickly on various ad hoc demands we had last minute. I can highly recommend Danny's services and I will use him again should the need arise.
