Raja Waqar Ahmad - PeerSpot reviewer
Suitable for use cases around multiple data centers and provides good stability
F5 is working on improving its identity management features. This is an important area for improvement, as it is a key component of Zero Trust architecture. So, when I was working on the zero-trust architecture, I noticed that there was a lack of documentation. The National Institute of Standards and Technology (NIST) has published some documentation and frameworks for ZTA implementation. In the NIST framework, multiple vendors can be used for different components of the architecture. For example, for identity management, common vendors include Azure, Intune, AWS, Cisco Duo, and Zscaler. I remember reading about F5 mentioned in the context of the ZTA framework. So, it's encouraging to read that F5 is being considered for ZTA implementations. Netskope is also using F5 for their ZTA solutions. I would also like to see all of F5's features integrated into a single box, as it would be the most beneficial for end customers. F5 is already enhancing its security capabilities. Initially, load balancing and security required separate devices, but now F5 offers solutions that combine both functionalities in a single device.

Simple solution and good WAF
Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section. Users get errors or EBAs, and if they want to read about it, they need to find it in the help section of the site. It would be more helpful to allow users to see more information and tips immediately from within the alert.

Quotes from Members

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

Pros

"The configuration process is straightforward, making it easy to set up wide IPs and distribute traffic across local US sites and data centers via VPN."
"F5 BIG-IP DNS is useful, depending on how you use it."
"F5 BIG-IP DNS has been rock solid in terms of stability for years."
"BIG-IP DNS's best feature is the Global Traffic Manager (GTM)."
"It is easy to administer."
"The management is very easy."
"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."
"The most valuable feature of the solution is security."
"The initial setup was very easy."
"The most valuable part is the analytics and visualization."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
"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."
"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."
 

Cons

"The monitoring capabilities of F5 BIG-IP DNS could be improved."
"I would like to see the login facilities improved, as well as more troubleshooting."
"In the product, one of the shortcomings is related to its configuration part...Though you can find some manuals or F5 documents, in real life, it's very hard to understand this product."
"I would like to see more marketing documentation, rather than technical documentation."
"I would like to see deeper integration with VMware in the sense that F5 compliments VMware, in the context of application availability."
"F5's technical support responds a little slowly."
"There is room for improvement in pricing. It is very pricey."
"The analysis services needs improvement."
"It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance."
"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."
"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."
"In terms of improvement, the cost factor is always there."
"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."
 

Pricing and Cost Advice

"You cannot do much around DDoS protection without an additional license from F5."
"In some cases, it is expensive."
"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."
"BIG-IP DNS is more expensive than its competitors like Citrix, but it gives good value for money."
"I would rate the pricing a three out of ten, with ten being a low price."
"They are competitively priced."
"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."
"Sucuri offers different plans, both the standard plan and an advanced plan. So there are different plans to choose from."
"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."

What do you like most about Sucuri?
The initial setup was very easy.

The pricing is very reasonable. Sucuri offer other features as an add-on, such as backup, but these have an additional cost. We host the sites ourselves, so I don't take it because it was redundant.
