Sentiment score
6.1
F5 Silverline's customer support is responsive but varies; users praise personalization but note challenges with escalations and response times.
The technical support team is very effective in resolving issues.
Support for Arbor DDoS deserves a rating of 10 because when there is a problem with implementation, the people I work with are the best.
Although the team is good, they are not fast, and they lack the skills to manage dynamic attackers.
Their support team is responsive, and they deliver timely updates, addressing any glitches promptly.
They resolve the issues by joining me to fix them.
 

Scalability Issues

7.4
Arbor DDoS excels in scalability, managing large attacks in telecom and banking, though pricing and planning affect deployment.
Sentiment score
7.8
F5 Silverline offers scalable managed services, efficiently handling enterprise demands with flexible expansion and seamless capacity management.
This would enhance the knowledge about scalability options available for Arbor DDoS, making it more accessible and useful for users.
I find Arbor DDoS to be very scalable.
At all locations where there is an Internet gateway, there is Arbor TMS that needs to perform that protection role from DDoS attacks.
F5 Silverline Managed Services is scalable enough without observed limitations.
The solution is fully scalable, and I would give it a rating of ten on a scale of one to ten for scalability.
 

Stability Issues

Sentiment score
8.3
Arbor DDoS is highly stable, reliable, often rated 8-10, but feature configuration during maintenance can be challenging.
Sentiment score
7.3
F5 Silverline delivers stable performance with strong monitoring, minimal downtime, effective support, and high stability ratings despite occasional issues.
It is a very stable product.
They offer regular updates, and overall, I would rate the stability of the solution as nine out of ten.
 

Room For Improvement

Arbor DDoS requires improvements in auto-mitigation, scalability, integration, pricing, support, reporting, and compatibility with older systems.
F5 Silverline needs improved pricing, integration, user interfaces, automation, API, and enhanced features like AI and bot detection.
I would like to see an option to decrypt the traffic with Arbor DDoS, as some clients are interested in this, particularly for application layer attacks on port 443.
Enhancing the handshakes between Arbor DDoS and third-party solutions is essential for obtaining better and real-time data that supports any organization’s support team effectively.
The licensing is subscription-based.
Introducing preemptive support prompts would reduce the manual effort required for creating policies or blocking specific IPs.
Improvements could include the creation of highly optimized profiles.
 

Setup Cost

Arbor DDoS pricing is high, but its superior protection and flexible licensing options justify the cost for enterprise buyers.
Enterprise users view F5 Silverline pricing as competitive but costly, with room for negotiation and flexible licensing options.
The prices for Arbor DDoS are expensive.
For some customers, the cost is expensive, but for enterprises looking to protect their services, it is affordable.
On a scale where ten is very expensive, I would rate the pricing as three.
The solution is expensive
 

Valuable Features

Arbor DDoS offers user-friendly, effective mitigation with hybrid integration, rapid detection, AI capabilities, and reduced false positives.
F5 Silverline Managed Services provides easy setup, robust security features, excellent scalability, and effective DDoS protection with comprehensive reporting.
That is an attack over 10 gigabit per second, and if an attack enters the telecommunication network, that will be a disaster for their customer, their services, and so on.
The feature I find most valuable is the packet capture, which beautifully shows the communication between the client and the server, identifying potential malicious activity.
The most valuable feature was the ability to detect attacks within two seconds and gain visibility of all the traffic.
It allows for centralized management of certificates, protecting applications from top ten attacks like SQL injection and cross-site scripting.
The monitoring tab displays GET and POST requests in a readable format, making it accessible even to non-tech-savvy individuals.

Rapid attack detection and traffic visibility improve security management
The solution was intended for the big clients of Telefonica to clean their internet pipe. We deployed the service to clean the pipe. In some clients' data centers, we implemented a solution that detects and mitigates attacks using Arbor DDoS, our data center solution For me, the most valuable…
Archana Heeralal - PeerSpot reviewer
A reasonably priced product with a good UI, but the navigation is difficult, and the support team takes a long time to respond
Since we use the solution’s cloud, the product has more control over the back end. The customer will not have control. It is part of the product’s feature. When we get more complex requirements or if we want to write more complex tools, the support team will have the visibility to write them because they have control. The navigation is difficult to use. The navigation should be improved. Other products are quite straightforward. If I try to implement a new application and do an onboarding, it is not very easy. We must go to one feature, inside which there will be more features. It should be simplified, and a menu should be provided.
