Fakturabörsen, a marketplace for invoices, opted for Detectify's security tool over pricier enterprise options due to its comprehensive and cost-effective approach to security testing. Andreas Larsson, CTO/Lead Developer, highlights Detectify's ease of integration, which requires only domain verification, eliminating the need for complex installations. The tool's ability to provide actionable suggestions for resolving vulnerabilities has been well-received by developers, despite occasional frustrations from test results. Regular weekly scans and additional tests with Detectify have enhanced their security posture, aided by seamless Slack integration and soon-to-be-available JIRA integration for automatic ticket creation. Larsson appreciates the ongoing research by Detectify's network of researchers who identify new vulnerabilities, allowing Fakturabörsen to focus on their primary goal of building trading systems while staying updated on security threats.
