Automated threat intelligence and flow-based mitigation have improved our DDoS defense
A very useful feature in Arbor DDoS is its ability to send flow spec announcements to routers. For example, if it is clear that a Layer 3 or Layer 4 attack is occurring and the attack pattern is identified through source and destination IP addresses and ports, you can generate flow spec filters. These filters are transferred through BGP to border routers, which automatically build filters, mitigating the attack even at the network's boundary and preventing it from reaching the TMS. This allows the TMS to focus on other tasks. This is a highly effective feature that can mitigate huge volumetric attacks; for example, we experienced a 32-gigabit attack, and all those 32 gigabits were dropped by our border routers, not by Arbor DDoS itself. The flow spec announcement was generated by Arbor DDoS, and as far as I know, the same technology is used by Radware, but it comes under a different feature and a different license. At the time, we were told that flow spec mitigation was an additional very expensive license to purchase from Radware, while Radware included everything in one package.

A cost-effective choice for website security and informative support with issues related to CDN quality
One area where they could improve is in providing real-time support options because now you need to open a support ticket and wait for their response. It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance. I have found their Content Delivery Network service to be lacking in quality, and it could certainly be enhanced to provide better performance. I would also like to see improvements in the deployment process, as it currently takes more time than desirable. Another significant concern is that their service when your website is down, turns it into a static site. This means that if customers try to visit your site during downtime, they will see old content from the static site, which is not ideal. The CDN and tracking services are areas that need improvement, as well as addressing their bandwidth limitations.

Quotes from Members

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

Pros

"It's just one dashboard with mitigation. You decide which mitigation you want and at what threshold to do this or that. Its operation is pretty simple. It's easy."
"Arbor has the ability to learn and self-create the appropriate profile for each customer, ensuring that false positives are kept to a minimum."
"The solution is easy to use."
"Its scalability is big. It is for large deployments of big organizations and service providers."
"I am convinced with the kind of scalability Arbor brings in; the Cloud subscription, which is available as one of its features, makes the scalability limitless."
"The solution provides good protection against volumetric DDoS attacks."
"The stability is okay and we have not encountered problems with the solution."
"It's very user-friendly."
"The initial setup was very easy."
"Domain name scanning since it allows us to scan all our domain names and determine whether it has malware or if is reported as phishing."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
"The initial setup was straightforward. Straight forward because the plugin can simply be installed and then it does its job. It's not complex, there is no learning curve. The online scan is simple, you put in the website address and the scan gives us a report on the browser itself. It's simple to use."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"Rather than locate some things manually, the Sucuri plugin scans and allows us to pinpoint whether there is malware or some problem in the site."
"For people who own a personal website, this solution is worth trying out since their security solution is somewhat full-fledged."
"The most valuable part is the analytics and visualization."
 

Cons

"The solution's shortcomings are related to its documentation, so it's an area that needs to improve."
"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."
"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."
"Implementation could be better."
"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."
"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."
"The support got worse after NETSCOUT acquired Arbor."
"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 main improvement I would like to see is support for .NET applications. If they could include this feature, I would include more sites in the protection."
"It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance."
"In terms of improvement, the cost factor is always there."
"Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section."
"I would rate this solution an eight out of ten. The reason is that we have found sometimes customers or Google saying that there is something wrong with the website but Sucuri says that the site is clean so we do have to look at the site manually which means that the Sucuri scan does not pick up anything and everything."
"Confident score: Currently it does not have one and there are cases that most websites flagged are false-positives."
 

Pricing and Cost Advice

"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."
"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."
"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."
"Arbor's products are very expensive. Their competitors are cheap when compared with Arbor."
"I'm a technical guy. But I know it's expensive compared to its competitors. After you have the on-premise solution, for your solution to be effective you have to subscribe to an "upper level," so there's another cost. There is also a subscription to cloud services, which is another cost."
"The price of Arbor DDoS depends on many parameters. It depends on the physical capacity of the environment, and it is not a straight-line price. It's fairly competitive in the market on the price."
"Pricing is slightly on the higher side."
"The price is a little high."
"The ROI has been very good. Because of the solution, I have a tax break. The site developers were not always experienced people. We used to pay more for cleaning up the site when it was infected. Now, we have peace of mind knowing that the solution will clean up the site and that we won't have to go through the unnecessary process of restoring it from a backup. The protection on the WAF and the measures for backups have also prevented our site from going down."
"I’d simply say it’s really worth it."
"Sucuri offers different plans, both the standard plan and an advanced plan. So there are different plans to choose from."
"It stands out as a more cost-effective option compared to other cloud-based security services like Cloudflare or JetPass."
