From my point of view, the biggest return on investment when using the solution is that it makes it a lot easier to delegate some of the tasks that were traditionally used, such as building policies on the firewalls and doing it through Cisco Umbrella.

The biggest return on investment when using Cisco Umbrella for me is the ease of use of the fact that we've deployed this with our Cisco VPN Secure Client, so every computer has the Umbrella module in it.

Room For Improvement

Cisco Umbrella needs enhancements in reporting, integration, user-friendliness, protection, licensing, infrastructure, and support for an improved user experience.
F5 BIG-IP DNS requires interface, pricing, and documentation enhancements, better security, improved integration, and faster support response.
Making it more flexible and easy to deploy, particularly when integrating with other technologies like Active Directory and proxies, would be beneficial.
Manager Cyber Security Department at Mana
The product can only shield a small area, making it less effective for larger spaces or multiple users.
Director at Infosonik Systems Ltd
I have to write an email to Umbrella support to get assistance, unlike the other products where I can call the Cisco technical assistance center and get an engineer.
CTO at Next Technologies Ltd
F5 BIG-IP DNS is not the best for DNS denial of service because they handle it as part of BIG-IP features, mainly used for GSLB, while other vendors provide complete DDI solutions, including DHCP, DNS, and IP address management, along with specialized DNS security, offering much more than just GSLB and basic recursive DNS security.
Solutions Architect at Mideast Communication Systems-MCS
The user interface could be more modern and simplified.
Associate Consultant at HCLSoftware
 

Setup Cost

Cisco Umbrella's pricing is fair yet varies, offering value in security coverage with opportunities to bundle for discounts.
F5 BIG-IP DNS offers valuable features but is costly, requiring either perpetual or subscription licenses, with mixed user reviews.
We've bundled that with our firewall stuff and our VPN, which brings the price down and adds the ability to grow.
Senior Network Engineer at Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C.
The only cost associated is the license cost unless additional solutions need to be integrated with Umbrella, which would incur extra costs.
Director at Infosonik Systems Ltd
The prices need to be lower as the current pricing is exceedingly high.
Network Solutions Architect at a financial services firm with 10,001+ employees
My experience with pricing, setup cost, and licensing was good.
Associate Consultant at HCLSoftware

The DNS layer security provided by Cisco Umbrella is very effective for our security posture, offering us vast improvements in visibility over DNS queries and potential threats.
Manager Cyber Security Department at Mana
The most valuable feature of Cisco Umbrella is its DNS security.
Network Solutions Architect at a financial services firm with 10,001+ employees
The best possible thing is that it is very easy to deploy, easy to configure, and very fast to get onboarded with a customer because this is a cloud-based service.

The best feature of F5 BIG-IP DNS is global server load balancing. It intelligently directs user DNS requests to the most optimal data center based on server health and geographical location, and it enhances performance.

Ensures comprehensive protection with seamless threat logging and efficient policy management
My favorite feature of Cisco Umbrella is probably just the DNS and the fact that when a security threat happens, all of that gets logged in their Umbrella portal, and it's very easy to find who's been accessing the site and how many people have accessed it, so that we can go to them and make sure they're not compromised. The features of Cisco Umbrella benefit my company by providing less time to search for things through logs, to look for what we need. It's just one place to go, and we just search for it, and we find it really fast. The fact that there's a virtual database that has all that information is great on our portal.

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.
