Results that Speak for Themselves

"Delta Security responds to any alarm activations in a timely fashion and they provide very detailed incident reports following these activations. I would have no hesitation in recommending Delta for your security service. They offer a very reliable and professional service and are very flexible in being able to cover any one-off attendance or special requests".

“Delta Security Management has provided a first-class service from the outset, proving to be consistently helpful and conscientious in working with us to improve the security of our premises. Their responses to callouts are prompt and their reporting is always thorough. They are very easy to work with and nothing seems to be too much trouble for them. I would not hesitate to recommend them.”



"We have only recently engaged the services of Delta Security Management, we have been extremely impressed by all of the services they have provided. The initial set up was made extremely easy and the transition was instant. We have had 2 incidents where we have required attendance to site, this was prompt on both occasions and dealt with swiftly, followed up the following day by a full report. We are looking forward to a good working relationship in the future"
