Executive SummaryUpdated on Dec 5, 2024

Arbor DDoS and Fortinet FortiDDoS compete in the realm of DDoS protection. Arbor DDoS holds the advantage due to its superior reporting, traffic visualization, and flexible deployment options.

Features: Arbor DDoS provides advanced reporting, real-time packet capture, and a hybrid protection approach, making it suitable for ISPs and large enterprises. Its precise traffic filtering significantly enhances security. Fortinet FortiDDoS offers specific protection resources and support, beneficial for targeted network defense, despite not offering the high-level insights that Arbor provides.

Room for Improvement: Arbor DDoS could improve its auto-mitigation to reduce the impact on legitimate traffic and enhance scalability with better integration with non-Arbor technologies. Fortinet FortiDDoS requires upgrades to manage higher bandwidths efficiently and could benefit from improved application traffic management beyond network layer protection.

Ease of Deployment and Customer Service: Arbor provides multiple deployment options, including hybrid cloud and on-premises, whereas Fortinet offers only on-premises deployment. Both receive positive remarks for customer service and technical support, although Arbor's support team is highly rated for its expertise and resolution efficiency.

Pricing and ROI: Arbor DDoS is priced higher but is seen to provide positive ROI, especially for larger enterprises, justified by comprehensive features. Fortinet FortiDDoS is cost-effective yet still expensive for SMBs, with limitations in scalability. Both solutions help maintain uptime and reduce potential financial losses from DDoS attacks, though Arbor's ROI stands out in larger deployments.

Has helped manage client domains with streamlined access control and threat visibility

I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

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:

Pros

"Easier http to https redirect using page rules"

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

"The solution automatically detects and responds to certain types of traffic based on geolocation."

"It is easier to configure and develop documentation to see how we have configured firewalls."

"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."

"The solution offers the flexibility to control configuration rules."

"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."

"I rate its stability a ten out of ten."

More Cloudflare pros

"Analytics and its attack mitigation capabilities are valuable features of the solution."

"Its scalability is big. It is for large deployments of big organizations and service providers."

"The most valuable feature is mitigation, which can blackhole the IP."

"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."

"The auto-mitigation, that signaling feature, where it automatically raises an alarm that a line is under attack, is important. The upstream service provider will then do something to reduce the load on our internet lines. The fact that it's automated means I don't have to sit and always be looking at threats coming through. It does it almost automatically, without any intervention by me."

"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 solution provides good protection against volumetric DDoS attacks."

More Arbor DDoS pros

"The protection resources and the support are valuable features of the solution."

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

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

"The product's initial setup phase was really easy."

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

"It is a user-friendly product in terms of monitoring and updating policies."

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

More Fortinet FortiDDoS pros

Cons

"Cloudflare could be improved by introducing a mid-tier pricing option."

"Support response time could be improved."

"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."

"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."

"There might be helpful if there was some web application firewall feature."

"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."

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

More Cloudflare cons

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

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

"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."

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

"The look and feel of the management console is a little old, excessively simple. If you compare it with other solutions, the look and feel of the console is like you're using technology from five or six years ago. It doesn't show all the technology that is actually behind it. It looks like an older solution, even though it is not."

"They should improve the reporting section and make it a little bit more detailed. I would like to have much better and more detailed reports."

"I think the diversity of protection is extremely limited. It must be expanded in future upgrades and versions."

"Based on my experience and feedback from colleagues, Arbor can make better use of the product because you have to spend a lot of time finding information in a huge number of papers."

More Arbor DDoS cons

"Alerts and reporting features must be improved."

"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."

"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."

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

"The solution can be a little more user-friendly and it can be more affordable."

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

"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."

"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."

More Fortinet FortiDDoS cons

Pricing and Cost Advice

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

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

"The product's pricing is cheap."

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

"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."

"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."

"That is one of the great features. I was able to access the majority of the features and services for free."

"A free version of the solution is available."

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 price is a little high."

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

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

"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 pricing of the solution is cheap."

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

"I don't know about the pricing details as our company's service provider offers us the solution as an inbuilt feature within the internet bandwidth they provide us."

More Arbor DDoS pricing and cost advice

"The solution is reasonably priced."

"The product’s pricing needs improvement."

"It's quite pricey."
