Advanced protection has secured critical web workloads and provides clear traffic visibility

From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

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.

Quotes from Members

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

"So far I use free tier and happy with it."

"CloudFlare has positively improved my site's speed, performance and security."

"The tool is user-friendly."

"Cloudflare's DNS services deliver the best performance in terms of speed and reliability."

More Cloudflare pros

"Mitigating network level volumetric attacks, complete network visibility and complete control on applying countermeasures."

"We found what we wanted in Arbor DDoS; it met our expectations as IT users of different types of complex environments and fit our needs."

"The ability to correlate Arbor managed objects with internet services deployed accurately profiles traffic and makes coordinating appropriate mitigation response simple."

"The solution is easy to use."

"The AI capabilities and anomaly detection using machine learning modules like isolation forests and auto-encoders are the most effective in mitigating DDoS attacks."

"With real-time packet capture features, you can easily and quickly response."

"When there was an attack, the attack was contained only on the IPs under attack, the rest of the network was not impacted, and that is the most important part."

"Arbor DDoS helps consolidate visibility on traffic and on DDOS attacks attempts, can perform direct mitigation action on the network, and has helped us achieve our network and application uptime goals."

More Arbor DDoS pros

"It is a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."

"I like the fact that the product provides a hybrid solution."

"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 very efficient and robust appliance."

"This is a hybrid solution."

"The DDoS protection features are valuable."

"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."

"The most important aspect, in general, is that the price is suitable for most clients."

More Corero pros

Cons

"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."

"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."

"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."

"The solution could work at being less expensive. It costs a lot to use it."

"For the services I am using, it is a bit expensive."

More Cloudflare cons

"Implementation could be better."

"I believe that the Arbor Cloud should be available, even if the customer does not have any Arbor appliance on-premise."

"A small improvement could be a better reporting system."

"The regional support here in African could improve, such as marketing and account managers."

"Auto mitigation is a feature provided when DDoS is observed on any of link/customer (configured under auto mitigation). It automatically starts mitigation with default filters. In default filter mode, there could be an impact on the customer’s link,"

"An improvement would be to provide information on how pricing is done on different customer levels."

"An improvement to Arbor DDoS would be to make evaluation licenses and virtual machines available."

"With Arbor DDoS, its integration issues with other technologies or other vendors' technologies is an area of concern that could be improved."

More Arbor DDoS cons

"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."

"It could use support in Spanish."

"The product must provide more Layer 7 capabilities."

"Juniper is known in our country, but it is not very popular."

"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."

"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."

"Lacks international presence."

More Corero cons

Pricing and Cost Advice

"The price of the solution is expensive."

"The price is reasonable."

"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."

"We are using the free version."

"We are using the free tier of the solution."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."

More Cloudflare pricing and cost advice

"The price of this solution is a little high in the African market, it should be lower."

"Start with a small license. Measure your bandwidth requirements."

"Pricing is slightly on the higher side."

"Arbor's products are very expensive. Their competitors are cheap when compared with Arbor."

"Arbor DDoS is quite expensive, but all these solutions are expensive because they deal with confidential information."
