Room For Improvement

Arbor DDoS needs improvements in automation, interface, third-party integration, pricing, support, documentation, traffic decryption, and WAF features.

Team Lead Network Engineer at Artco Group d.o.o Sarajevo
Reliable protection ensures robust network defense and simplifies DDoS management
I am not sure if we plan to use additional features because we have many vendors and platforms that we support. We use the main function and that is it. The prices for Arbor DDoS are expensive. The licensing is subscription-based. From our sales department, they discuss that prices are very high. A potential improvement could be establishing a contract with Cisco to sell via their channel. This could be beneficial because we work extensively with Cisco. If you are a Cisco partner, you can sell Arbor DDoS. That would be good for customers that are Cisco-based because many customers in Bosnia are Cisco-based customers. BH Telecom, our main customer, sells Arbor DDoS to other customers for protection. They buy Arbor and sell the product services to others via Internet links. They sell add-on DDoS protection via Arbor DDoS. In Bosnia and Herzegovina, Arbor DDoS is not present in many customers. Some customers try to sell it, but they sell other vendors such as F5. Arbor DDoS is mainly seen in telecom operators but not much in other customers.

Displays flexible, user-friendly interface with minor licensing challenges
The product could be improved with a more intuitive interface for complex configurations and more advanced analytics. Additionally, enhanced security features, like a more robust Web Application Firewall, and stronger APIs for better automation would be beneficial. Overall, the main areas for improvement are in strengthening the advanced features to better meet the demands of large-scale enterprise environments. key features for the next release should focus on three areas. First, an enhanced, next-generation security suite with a more powerful Web Application Firewall (WAF) and integrated bot protection. Second, more advanced and customizable analytics dashboards to provide deeper insights into application performance. Finally, greater support for modern, cloud-native environments, including better APIs for automation and seamless hybrid-cloud traffic management
