The round came six years after the company’s $14.5m Series C, which was led by CMEA.
Trident Capital managing director Alberto Yepez said, “AirTight has been a leading innovator in the wireless space since the company’s inception, bringing the industry’s top-rated WIPS to market in 2005 and the first cloud-managed Wi-Fi security solution in 2008.
“The management team demonstrated great skill and discipline driving the company to profitability and positive cash flow in a highly capital-efficient manner.
“Following its initial success in wireless security, AirTight now has an even greater opportunity to lead the way in next-generation Cloud Wi-Fi solutions.”
Last year Trident led a $25m Series D for smart security platform Mocana.
