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.

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

M.A. Faisal

General Manager at bKash Limited

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.

Quotes from Members

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

Pros

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

"The most valuable features include the traffic categorization and control of the traffic. The filtering of the traffic is very precise. When you want to stop some traffic, you precisely stop that traffic."

"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 artificial intelligence feature is most appreciated. This solution can lower the throughput and clear the traffic, which is something really important for us. It also provides good protection. It is user-friendly, and its integration has also been really fast. We have many critical applications, and it was easy to integrate Arbor DDoS with our website, mobile application, and web banking."

"There were huge attacks in October, around 62 attacks at 30 gigabits per second, at one of our banks. We used Arbor DDoS to mitigate these attacks, and it performed great."

"We use it not only for DDoS detection and protection, but we also use it for traffic analysis and capacity planning as well. We've also been able to extend the use of it to other security measures within our company, the front-line defense, not only for DDoS, but for any kind of scanning malware that may be picked up. It's also used for outbound attacks, which has helped us mitigate those and lower our bandwidth costs..."

"Companies that live from their presence on the internet will get a very high return on investment from Arbor."

"The quality of the technical support provided by Arbor DDoS is premium."

More Arbor DDoS pros

"It's very user-friendly."

"It is a fast and secure DNS."

"Generally, I am satisfied with this product."

"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."

"Easier http to https redirect using page rules"

"The DDoS protection is the most valuable aspect of the solution."

"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."

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

More Cloudflare pros

"We have researched them all, and it's a good solution all around."

"It allows me to see all the traffic on my network."

"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."

"The product allows the users to adjust the thresholds."

"Packet inspection has been effective for mitigating DDoS attacks."

"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."

"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."

"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."

Cons

"It is an expensive product, so there is room for improvement in terms of pricing."

"For troubleshooting problems, it's not so intuitive. It's not straightforward. This is the core of their kernel, so they need to improve it a little bit... In F5 I have full control of everything."

"I think Arbor DDoS needs improvement in areas where competitors like S5, Redver, or NETSCOUT offer web application firewall functionality or dedicated web application firewall devices. Arbor lacks these features, which is a significant disadvantage. Yes, I would like to see these features introduced in Arbor as well. Regarding real-time detection capabilities, Arbor DDoS works very well. We and our customers are very satisfied with its performance. However, it would benefit from adding Web Application Firewall (WAF) capabilities to reach a larger customer base."

"Real-case scenarios that have taken too long to resolve or were escalated can be directly converted into articles."

"The following areas need improvement: opening and tracking support tickets, online support resources, software upgrades/updates and replacement media, and event management guidelines."

"The product could have end-to-end platform visibility."

"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."

"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."

More Arbor DDoS cons

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."

"There should be a specific price list for enterprise-level customers."

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."

"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."

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

"The solution could be more user-friendly."

"Cloudflare should add more documentation and pricing to the cloud version."

More Cloudflare cons

"The web interface could be much better."

"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."

"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."

"I find that there have been issues in the past year with the solution hanging. It freezes often."

"I would like to see analytics, big data."

"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."

"Alerts and reporting features must be improved."

"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."

Pricing and Cost Advice

"We do not use the Arbor Cloud DDoS solution because it is too costly."

"Regarding pricing, I would rate it as average. Arbor DDoS offers good value for money with our DDoS filter device. For higher protection needs, Arbor’s CloudMeter’s DDoS mitigation or hardware devices might be more expensive, but customers who need them are usually prepared for the cost and the additional resources required."

"It is an expensive product. I use this product for its different features."

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

"Because the solutions from competitors are very different, it's not easy to compare. However, the licensing from Arbor is clear and understandable and the pricing is reasonable when looking at the market, in general."

"The solution is a bit costly if you're a small organization, but I think it's worth the price that they are charging."

"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."

"The pricing of the solution is cheap."

More Arbor DDoS pricing and cost advice

"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."

"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."

"The product's pricing is minimal compared to other products."

"There are no additional costs beyond the standard licensing fees."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"The product's pricing is cheap."

"The price of the solution is expensive."

"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."

"It's quite pricey."

"The solution is reasonably priced."

"The product’s pricing needs improvement."
