Welcome back to the FCR Media News ongoing series dedicated to highlighting Ireland’s top businesses, county by county. This time, we’re turning our focus to the capital to find the Best Security System Suppliers in Dublin.
The competition for the top spot was fierce, immediately demonstrating the incredibly high standard of security businesses operating across the county. To ensure this list represents the absolute elite, we employed a rigorous methodology: any business with fewer than 30 reviews and any business with a Google Star Rating lower than 4.9 was excluded.
Our ranking is strictly based on objective data gathered from Google Business Profiles: the primary factor is the Google Star Rating. Where multiple businesses share the same star rating (a frequent occurrence in this high-calibre list), we give the higher ranking to the company that has received the greater number of customer reviews. The resulting list of 13 companies represents the undisputed pinnacle of professionalism, quality, and customer satisfaction in Dublin’s security industry.
Now on to the list.
13. Aztec Security
4.9(37)
Coming in at number 13 on our ranking is Aztec Security, which has earned an impressive 4.9-star rating across 37 Google reviews.
