we have been setting up a test-bed to evaluate different Web Application Firewalls. To generate malicious traffic we are currently using @sqlmap, the "Nikto" Web server scanner and @kalilinux’s XSSer. Any other suggestions?

to address challenges (e.g. faster release pace, reliability) related to new services developed by @grnet, we opted for cloud native patterns and practices. Currently, through @kubernetesio we are managing multiple services running smoothly on our infrastructure! #K8s #DevOps
