Global load balancing has ensured continuous availability and optimized user response times
While F5 BIG-IP DNS is a very powerful solution, some improvements could enhance the overall experience. For example, the user interface could be more modern and simplified. The reporting and analytics features can be improved. Simplified deployment for cloud-native environments could be improved. Overall, F5 BIG-IP DNS is a robust and reliable solution for global traffic management and application availability. With its advanced traffic steering capability, we are definitely getting great benefits from that. However, the user interface is the major thing I think can be improved. The cost also can be reduced. Those are the two or three points that need to be improved. There is some scope for improvement, including the user interface and pricing. That is why I gave it a nine.

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

"One of the most effective feature of F5 BIG-IP DNS is its robustness and integration with our existing F5 infrastructure. It helps us to geographically connect and form an internal topology network with our clients."
"BIG-IP DNS effectively handled a traffic surge. For example, we have application forms replicated across our DCs. If our primary application becomes unavailable, BIG-IP automatically fails over to a client-unaware secondary application."
"BIG-IP DNS's best feature is the Global Traffic Manager (GTM)."
"The most valuable features are DNS security and the speed of operations."
"F5 BIG-IP DNS stands out as they are number one when it comes to WAF and load balancing technologies, and they have plenty of add-on features such as APM and AFM to handle DDoS attacks, DNS security, and GSLB."
"BIG-IP DNS is more expensive than its competitors like Citrix, but it gives good value for money."
"F5 BIG-IP DNS is a stable solution."
"BIG-IP DNS's best features are DNS monitoring and global service load balancing."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
"The most valuable part is the analytics and visualization."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"For people who own a personal website, this solution is worth trying out since their security solution is somewhat full-fledged."
"The initial setup was very easy."
"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."
"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."
"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."
 

Cons

"It would be great to see a F5 BIG-IP DNS cloud version. What we within the Australian government are looking at doing is utilizing a secured DNS service much the same as the English GCHQ version of their protected DNS service."
"The weakness is that extensive training is required to hire the people who need to work on the project."
"I would like to see deeper integration with VMware in the sense that F5 compliments VMware, in the context of application availability."
"The analysis services needs improvement."
"The solution's initial setup is complex compared to Fortinet."
"The costs could always be a bit lower."
"The messaging between NGINX and F5 should be simplified."
"When it comes to denial of service or DNS security, F5 is not the best vendor as dedicated vendors such as Arbor for denial of service and Infoblox for DNS security offer more comprehensive solutions."
"Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section."
"Confident score: Currently it does not have one and there are cases that most websites flagged are false-positives."
"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."
"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."
"In terms of improvement, the cost factor is always there."
"It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance."
 

Pricing and Cost Advice

"I would rate the pricing a three out of ten, with ten being a low price."
"The on-prem version is only available on a yearly license, but the cloud version can be paid for on a day-by-day basis."
"You cannot do much around DDoS protection without an additional license from F5."
"Cost is a factor. It is really costly."
"This product is quite pricey but if you compare the feature set and its compatibility with similar products on the market, you would understand why it's that price."
"They are competitively priced."
"BIG-IP DNS is more expensive than its competitors like Citrix, but it gives good value for money."
"In some cases, it is expensive."
"I’d simply say it’s really worth it."
"It stands out as a more cost-effective option compared to other cloud-based security services like Cloudflare or JetPass."
"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."
"Sucuri offers different plans, both the standard plan and an advanced plan. So there are different plans to choose from."
