Ierabu Group Partners with Rest Solution for Web Application Features

Ierabu Group Collaborates with Rest Solution



Ierabu Group, a pioneer in the DX support services for the real estate industry, has recently announced a new partnership with Rest Solution, a company providing rental guarantee services. This collaboration enables users of the "Ierabu BB" platform to efficiently utilize a web-based application feature that integrates with Rest Solution's rental guarantee services.

Background and Overview



Founded in 2008 and headquartered in Shinjuku, Tokyo, Ierabu Group aims to create a reliable environment for housing selection. Its real estate DX Division is at the forefront of developing specialized services for the real estate market. Rest Solution, based in Chiyoda, Tokyo, focuses primarily on rental guarantee services for tenants, landlords, and rental companies. Their platform offers comprehensive solutions ranging from tenant screening to support during default cases, legal proceedings, and more.

As part of this new integration, the Web application feature on the Ierabu BB platform now allows for online applications for rental guarantees, streamlining the application process. Property management companies that utilize Rest Solution's services can manage all aspects of application submission—including updates like changes or cancellations—directly through the interface, significantly enhancing operational efficiency.

Enhanced Features and Security



One of the key aspects of this integration is the use of an API that adheres to the OWASP ASVS standards. This ensures secure data transfer during the application process, providing peace of mind to all parties involved. By leveraging such security measures, Ierabu Group is committed to promoting a trustworthy and efficient digital ecosystem for real estate transactions.
