CoStar Group – Belbex.com


Part of US-based CoStar Group – with a presence in the USA, Canada and Europe – Belbex.com is an open portal where tenants, buyers and investors can find their ideal property quickly, easily and securely. This real-estate information and marketing platform specialises in offices, warehouses, plots of land and other properties, as well as rental and sales for small private buyers and large investors alike. Most of Belbex.com’s business is currently centred in Madrid, although expansion to other Spanish cities is being planned. The CoStar Group portals are visited by 37 million tenants and buyers around the world each month. With nine million daily searches, searches on CoStar Group portals make up 83% of all Internet searches for offices, warehouses and venues. In 2016, their users closed over one trillion dollars’ worth of transactions through internal and third-party portals.

The company was looking for a way to allow portal users (suppliers) to maintain data privacy, while also providing end-to-end tracking of contacts made through online ads. In the first phase, Colt needed to provision enough phone numbers to assign a unique one to each real estate ad. This meant having access to a lot of available numbers, implementing a system to manage those numbers, and applying security measures to prevent external threats to the platform.

Belbex.com also needed to track all telephone activity for every listing on the portal, while simultaneously maintaining confidentiality for all ads. Once the ad is removed, the advertiser no longer receives calls. Such commitment is costly for Belbex.com, since each ad has its own unique number. “We currently have a high volume of numbers, and this will only continue to grow.” With Colt’s ability to provide numbers in different markets, Belbex.com can now expand the service to the 13 countries where Colt operates. This will make it possible to send and receive calls from anywhere in the world through a single web interface. Data security was also a key requirement for which Colt deployed an end-to-end private link with a Colt Ethernet connection between Belbex.com and the Colt INteractiv platform. This private link also helps deflect DDoS attacks since INteractiv can only receive data from the Belbex.com link.

Colt’s comprehensive solution frees us from managing all of the active telephones as well as their programming, statistical control and consumption. We receive actionable insights for the entire flow of communication, which in turn simplifies technology management and drastically reduces operating costsJuan Ramón Trujillo, CTO at Belbex.com
