Room For Improvement

Enhance Link11 with intuitive interfaces, real-time alerts, automated reporting, improved WAF, unified panels, and better bot management.
I would like to see an option to decrypt the traffic with Arbor DDoS, as some clients are interested in this, particularly for application layer attacks on port 443.
Network Engineer at A1 Bulgaria
I would like to see a roadmap for one or two years, and it is tough to predict what will happen in that timeframe without a clearer description.

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.

Offers flexibility with a kill switch for bypassing Reblaze if needed and provides a reliable Layer 7 defense against attacks
There is still some room for improvement when it comes to bot management from Reblaze because they are relatively new compared to other vendors in the town. AWS WAF, the Web Application Firewall from AWS, has a vast database of bad IP addresses due to its long-standing presence in this business. Reblaze, being a new entrant, is still building its database of bad IP addresses and malicious systems. So, Reblaze needs to work on that aspect. But other than that, I don't think scaling Reblaze has been an issue. There were some initial glitches, but they were all sorted out. So currently, I would say that the bot management and the database are areas they should focus on for further improvement.
