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.

Customer interface and support have impressed while artificial intelligence features drive confidence

Arbor DDoS has some difficult pricing rules. For many different small features, we have to pay additional fees for every small feature. If we compare it, it is slightly high and not very affordable. If I compare it to automobiles, when you buy Volkswagen and then consider Skoda, for the cheapest way, you would buy Skoda. But if you want similar features to Volkswagen, you have to pay a little bit more than for Volkswagen. As I mentioned, a good way would be to buy some package of features at small prices. That is one of my recommendations for the company. 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.

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

"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."

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

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

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

"Cloudflare has made management of my website much easier by combining various functions in one platform without compromising quality."

"CloudFlare's caching brings the load speed down from 4.32 seconds to 2.45 seconds."

"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"

More Cloudflare pros

"Valuable features include simple and centralized management of user access and capabilities, as well as Web 2.0 interactive attack alerting, traffic visualization, and mitigation service control."

"Arbor DDoS is used for network protection if you have a DDoS attack, it keeps the session or information moving."

"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..."

"I highly recommend Arbor DDoS to others."

"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."

"I recommend using Arbor DDoS for those wanting to keep their services online."

"The most valuable feature of Arbor DDoS is that it is based in most of the ISPs all over the world, and Egyptian ISPs are one of them."

"We have taken on the Arbor Cloud subscription, which is really useful because you secure yourself for anything beyond your current mitigation capacity. This is a really good feature of Arbor that is available."

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."

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

"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."

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

"It is a very efficient and robust appliance."

"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."

More Corero pros

Cons

"I think they have failed with their technical support."

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."

"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."

"DNS Management."

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."

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

More Cloudflare cons

"The prices for Arbor DDoS are expensive. The licensing is subscription-based."

"When it comes to some false positives, we need to tweak the system from time to time. There is room for improvement when it comes to the actual mitigation because of some false positives."

"If we want to see live traffic, we can do so, but once an attack that lasts for five minutes is done, the data is no longer there."

"The solution could be more granular to include logs per second and enhanced pipeline monitoring for router licenses."

"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."

"There are some price issues with scalability, but technically speaking, the solution is fully scalable."

"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."

"Cloud signaling integration with third-party DDoS solution provider. Currently, it supports only its DDoS APS box."

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."

"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."

"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."

"It could use support in Spanish."

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"Lacks international presence."

"The product must provide more Layer 7 capabilities."

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

Pricing and Cost Advice

"The product's pricing is cheap."

"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."

"The solution is expensive when compared to other products but offers unlimited bandwidth."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

"We don't have any issues with the price."

"The price is reasonable."

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

"I give the price a five out of ten."

More Cloudflare pricing and cost advice

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

"The licensing of a complete Arbor solution, including fire-walling and unified site management, can get expensive."

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

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

"There is room for improvement with the pricing. It is an expensive solution. The issue with the pricing is more the way it is built. Right now we're paying per router, and there's a limitation there. I would like to see bundle-pricing where there is an overall solution cost."

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

"Arbor is striking a good balance between pricing and what they deliver."

More Arbor DDoS pricing and cost advice

"Its price is normal."

"The price of Corero is affordable."
