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.

Effective network and DDoS protection with suitable pricing
I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Because this Arbor DDoS product is the best, I do not need to spend time supporting it."
"We are able to respond quickly and prevent DDoS attacks."
"It provides packet capture and we can block or whitelist whichever IPs we need to. Whatever traffic we want to block - and we get IPs from internal teams and from national teams - we block at the Arbor level only, because if it gets to the firewall then firewall bandwidth will be taken."
"The AI capabilities and anomaly detection using machine learning modules like isolation forests and auto-encoders are the most effective in mitigating DDoS attacks."
"The stability is okay and we have not encountered problems with the solution."
"Arbor DDoS's best feature is that we can put the certificates in, and it will look at layer seven and the encrypted traffic and do the required signaling."
"Its scalability is big. It is for large deployments of big organizations and service providers."
"Reporting is quite good. There are several pages of reporting on DDoS attacks, and you can find all the details that you need."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"This is a hybrid solution."
"The most important aspect, in general, is that the price is suitable for most clients."
"The DDoS protection features are valuable."
 

Cons

"There is always room for improvement for any product or service. If we can bring in more agility when deploying services, that is definitely a scope which we can work towards. Nowadays, everything is being offered as a service model. It is not that we have to deploy the physical hardware, many things move up to the cloud, or even can be delivered in the VNS form in the customer's environment as well. So, in that space, if we can add more features to make it more seamless for customers to use and make it available through some marketplace, not only at the hyperscalers, but also for any on-prem deployment, that definitely would be a big plus."
"The prices for Arbor DDoS are expensive. The licensing is subscription-based."
"Because we had some routers that were somewhat old, they were not integrated with Arbor. They did not support the NetFlow version that Arbor was running. That was a challenge. We had to upgrade the routers. Some backward-compatibility would be helpful."
"I would also like more visibility into their bad actor feeds, their fingerprint feeds. We try to be good stewards of the internet, so if there are attacks, or bad actors within our networks, if there were an easier way for us to find them, we could stop them from doing their malicious activity, and at the same time save money."
"Sometimes it blocks legitimate traffic. If a legitimate user is trying to access the server continuously, the product suspects that this is a DoS traffic file. That is a case where it needs to improve. It needs machine-learning."
"An improvement would be to provide information on how pricing is done on different customer levels."
"On the application layer, they could have a better distributed traffic flow. They could improve that a bit. For network data it is very effective, but the application layer can be improved."
"They also have limited sizes of the boxes. Different sizes are needed because some customers are very small while others are very big, such as ISPs, so this categorization should be available."
"The product must provide more Layer 7 capabilities."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"It could use support in Spanish."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"Lacks international presence."
 

Pricing and Cost Advice

"Arbor DDoS is quite expensive, but all these solutions are expensive because they deal with confidential information."
"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."
"As far as I know, they are the best in this sector, in DDoS protection. They know it, I know, because their service prices are too high. They provide cloud DDoS protection for ISPs, but that is also too expensive."
"You need to find a way to get a good offering from Arbor by negotiating a price. That is the challenge."
"The pricing of the solution is cheap."
"The price of this solution is a little high in the African market, it should be lower."
"It is an expensive product. I use this product for its different features."
"I don't deal with the pricing, but it seems that you need to get basic support in order to upgrade the software and implement some patches."
"Its price is normal."
"The price of Corero is affordable."
