What is our primary use case?
It is our ISP, from where we get our internet traffic. We just send it to them and if anything is suspicious or there is some malicious traffic, we talk to them about what kind of traffic it is. If some machine or some router is being attacked by a malicious user, we try to find out the source IP and why this traffic is coming to us. The Arbor solution is deployed on their premises. We just ask them to control or just stop that traffic. They do the filtration. They provide us all the required details to mitigate an attack on any particular machine.
How has it helped my organization?
Arbor DDoS is a quick solution when you have identified some of the originating suspicious IPs from which you are getting traffic in your network. If you have identified that some of the email gateways, or any of your web applications, or any of your routers are being attacked, it is effective. You can ask your ISP to block such queries. If the originating IPs are dynamic, it is a little bit difficult for them to identify and block the traffic, but to a certain extent you can minimize the DDoS attack impact with this solution.
In application layer DDoS attacks, it suggests the actions that should be taken. But at the network layer, you can simply block the originating traffic IP and block the port instantly. It depends on how proactive you are and how effective your incident response team is. Once traffic has started on any of your machines, it can be very difficult to manage it, but you can minimize the impact of malicious traffic with the Arbor tool.
What is most valuable?
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.
What needs improvement?
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. In today's era, attackers are also developing their skills. Daily, new threats are coming into the environment.
For how long have I used the solution?
I've been using Arbor DDoS for almost seven years. I am the cyber security architect in our company and we have a SOC manager. We work together as a team and we are the only two people who use it.
We do have a team and they instantly contact the ISP if any malicious source IP has been detected. It has been about six months since we have faced an incident in which we had to reach out to our ISP to block some traffic. We then isolated that machine later on. We instantly blocked that port and signature file. Our SOC team works on the operations part.
What do I think about the stability of the solution?
The stability of Arbor DDoS is excellent, whether it is hardware or software stability. Whatever rules are set up inside, it's excellently developed and it excellently manages your good and malicious traffic.
What do I think about the scalability of the solution?
In terms of scalability, it's also excellent. DDoS attacks are not very scalable, but compared with other tools, in terms of mitigating those non-scalable DDoS attacks, it is better. In that way, Arbor is scalable. It is very effective when it comes to mitigating or dealing with DDoS attacks.
We have four SOCs deployed here, and my SOC has one lakh EPS (event per second) capability. It is a big network and we use the biggest telecom operator in India. We just deal enterprise and telecom traffic.
How are customer service and support?
The support is fine. The ISP team works directly with the Arbor team, so they would have a better idea about that part, but from what I know the support is excellent.
How was the initial setup?
We don't have the Arbor solution deployed on-premises. It's with the ISP, so I wasn't involved in the setup or the implementation.
Which other solutions did I evaluate?
Arbor is the most effective solution, when compared with other tools. Although I only have experience with Arbor, I have read a lot about other tools. Today, attackers are developing their skills like anything. When some of your workstation IPs are hacked, or some of your application vulnerabilities are exposed, Arbor solutions are very much effective. Although you may have very limited competency or tools to deal with today's DDoS attacks, Arbor is effective.
Arbor is very precise as far as network layer traffic monitoring and control are concerned, but in my opinion EDR is a better solution when it comes to the application layer and DDoS. Arbor has its modules but EDR is a better solution to mitigate the application layer DDoS attack.
What other advice do I have?
Arbor's hybrid approach to DDoS protection is both an advantage and a disadvantage. Sometimes it is not able to filter traffic adequately because of the hybrid approach. It only takes action after a bit of time. It starts acting on malicious traffic a little bit late because of the hybrid approach. On the other hand, after seeing all the aspects, the analysis is sensible and perfect. So it depends on from which side we look at this feature.
Network layer DDoS attacks are absolutely big. DDoS attacks cannot be mitigated instantly, it takes time. You have to be very aware of your network and about which machine an attack has reached, and what the network architecture is. All those aspects are responsible for the impact of DDoS attacks. Arbor is not absolute but, comparatively, I find it to be an effective solution.
Overall, it's a great product. It is a very effective product in terms of dealing with DDoS attacks, whether it is network layer attacks or application layer attacks. But it is better in network layer DDoS attacks. It is among the best.
