We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"It is a good cloud-based solution for DNS security.""Cisco Umbrella is such a solution and can be implemented very fast and easy. All that we must do is redirect the DNS registers in their routers, or the active directory service of the enterprise that are going to use in Umbrella services. If you buy the service now, in two hours you are protected by the service because it's very fast to put in service.""The single-pane-of-glass management is really important. In today's era, administration costs and operational expenses will cost you a lot, and it reduces that as well. You don't need extra resources to manage all your parameter firewalls, looking at every single device to allow resources internal access. By just introducing the single-pane-of-glass management, it has lifted the burden off of management, especially the network management.""We can have a full overview and a quick overview of all the DNS requests. For us, it's quite important.""Cisco's technical support is pretty good. When a solution is available, they will find it. On a scale from one to ten with ten being the best, I'd rate Cisco's technical support at nine.""Application performance has greatly improved and there are less operational issues. Productivity has been going up because we have less operational issues. Also, we have happy customers.""There is much differentiation within the licensing so if anyone wants DNS security from the DNS security log, we are there already, and if anyone wants to go to a secure internet gateway, that is also available. We can get the integrated cloud DLP license keys. That is a good benefit with Cisco Umbrella. You can get a complete solution in a single licensing.""It enables us to go granular in the customization of blocking some categories on the DNS."

"The most valuable feature of Quad9 is that it is a free solution."

More Quad9 Pros →

"We don't have to buy equipment to use it. And when our engineers set it up on our side, we just configured a few settings and we were in.""The initial setup is very straightforward.""I like the granularity of the control of all the traffic, including SSL inspection. I also like the fact that the user interface is intuitive. The latencies with Zscaler are minimal compared to those of any other competitor. Other competitors do not really have the global scale that Zscaler has and cannot promise low latencies.""The solution is stable and reliable.""The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users.""The most valuable features of Zscaler Internet Access are it's on the cloud, high network performance, and the interception of users is very easy.""The most valuable feature is the ability to drop packets.""The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."

Cons
"The design of the screens could be improved. Sometimes you're trying to look for information, for what you think is critical that should be on that first screen of the dashboard so that you can quickly take screenshots to have people help out, but you have to hop between screens to find little pieces of evidence.""The locks and management could be better. The product is fairly new, and it may take some time to get all the features up and running.""The price could be better. The price is definitely a bit high, but we have to pay a premium for Cisco products.""Network connectivity was a bit of a challenge at the beginning, but we were able to get the right help from Cisco.""It could be more secure. It would be better if they provided a transferring proxy as an add-on and more integration.""It had the ability to do a lot of app control. So, every single app that went through that portal was registered, but there is a general issue with the whole app control. As soon as you add a mobile phone to your network, all of the apps get registered through the system, and you can approve, reject, or just let them go through. When I looked at it, it was impossible to manage app control. There was just so much data. I didn't apply that service because I just didn't have the time to manage it. It would be good if there was a way to categorize applications.""In my experience with Umbrella support, sometimes the response times take a bit more time than we would like... sometimes, if you go through email, it can take quite a while to get a response.""Having ready-to-go templates with best practices is definitely something that would be an improvement. Deployment, from day one, is something that definitely needs to be improved for Cisco customers."

More Cisco Umbrella Cons →

"Quad9 could improve by having more free features, such as custom DNS filtering."

More Quad9 Cons →

"I would like to see more training and video documentation.""We'd like to have more plugins and integration.""Technical support could be better.""The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments.""One thing that they could improve is the ability to import rules from other platforms.""The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again.""The main issue with Zscaler Internet Access is proxy IP detection, which sometimes makes sites inaccessible.""What could be improved in Zscaler Internet Access is its price. It could be cheaper."

Pricing and Cost Advice
  • "It has a reasonable price. It is certainly not as expensive as it used to be. It is in line with other offerings on the market. There are a number of different flavors of Umbrella. They could bring Umbrella SIG down a bit because its price is a little bit high for what it does, but I also understand why its price is high."
  • "Cisco Umbrella is expensive and could be cheaper."
  • "When talking about Cisco solutions in general there pricing model is horrible. For example, you can sell a Meraki-based solution, but if the customer starts shopping around, someone is going to have access to the pricing at a level that you cannot compete because they do not have uniform pricing. Not everybody gets fair pricing. Unless you are one of the real major corporations selling the solution your ability to compete is impossible. Cisco will acknowledge the situation and assure you next time it will be in your favor but it never becomes favorable for you. Cisco is not very good in this regard. However, Umbrella is good."
  • "The licensing fee is paid on a yearly basis."
  • "In the region I'm from, that of EMAR, Europe, the Middle East, Eastern Asia and Africa, our organizations do not have many liquid cash assets, so the price could be better."
  • "The price depends on the use case, and it's a bit linear. But it depends on the customer's strategy and how Cisco plans to optimize the costs."
  • "We were using the free version, and we implemented the paid version about two months ago. I'm paying a fair price, but everything is negotiable with Cisco. One of the benefits that I got by having Cisco Umbrella is the licensing of the Cisco AnyConnect VPN client."
  • "There are no hidden costs with Umbrella. Everything is included in the package."

  • "The price of Zscaler Internet Access should improve, it is expensive."
  • "We have found the solution to be expensive."
  • "Licenses are available on a per-host basis. Some features like sandboxing require an additional fee, but most standard features are included in the license."
  • "We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
  • "Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."

    Overview

    Cisco Umbrella offers flexible, cloud-delivered security according to users’ requirements Cisco Umbrella includes secure web gateway, firewall, and cloud access security broker (CASB) functionality all delivered from a single cloud security service. Cisco Umbrella’s protection is extended to devices, remote users, and distributed locations anywhere. As company employees work from many locations and devices, Cisco Umbrella is the easiest way to effectively protect users everywhere in minutes.

    Cisco Umbrella uses machine learning to search for, identify, and even predict malicious domains. By learning from internet activity patterns, this DNS-layer security solution can automatically identify attacker infrastructure being staged for the next threat. These domains are then proactively blocked, protecting networks from potential compromise. Cisco Umbrella analyzes terabytes of data in real time across all markets, geographies, and protocols.

    Cisco Umbrella works with leading IT companies to integrate its security enforcement and intelligence. Built with a bidirectional API, Cisco Umbrella makes it easy to extend protection from on-premises security appliances to cloud controlled devices and sites.

    Cisco Umbrella is suitable for small businesses without dedicated security professionals, as well as for multinational enterprises with complex environments.

    Why use Cisco Umbrella?

    • Simplify security management: Cisco Umbrella is the fastest and easiest way to protect all users within minutes and reduces the number of infections and alerts sent from other security products by stopping threats at the earliest point. With no hardware to install and no software to manually update, ongoing management is simple

    • Reliable reporting: Cisco Umbrella reports show activity for each device or network in the system. Users gain a more complete picture of the security risks facing their organization and can take action to remedy them.

    • Manage and control cloud apps: Umbrella provides visibility into sanctioned and unsanctioned cloud services in use across the enterprise. Users can uncover new services being used, see who is using them, identify potential risk, and block specific applications easily.

    Reviews from Real Users

    Cisco Umbrella stands out among its competitors for a number of reasons. Some of the major ones are its DNS-based protection, ability to protect users no matter where they are located, stability, and high performance.

    Daniel B., a network specialist at Syswind Kft, writes, “We primarily use the solution as cloud security for our branches. It protects us from direct internet outbreaks. It makes for good flexibility. The solution is very easy to manage. We found the initial setup, for example, to be quite simple. Efficient protection on the DNS level and even higher. The sandboxing feature analyses and handles the complicated security risks.”

    Victor M., SOC & Security Services Director at BEST, notes, “It provides security for the remote workers and it helps to improve enterprise security in a very easy way. We mainly enjoy web software protection capabilities. It prevents the end-users from getting into bad sites or sites that potentially could have malware or could be phishing. It helps end-users avoid the wrong sites. The solution works very smoothly. The user interface is good.”

    Quad9 is a free, recursive DNS service that replaces your ISP's or company's default domain name server (DNS) settings. Quad9 blocks lookups of malicious host names from an up-to-date list of threats when your computer makes any internet transaction that uses the DNS.

    This blocking action protects your computer, mobile device, or IoT systems against a variety of risks, including malware, phishing, spyware, C2 command-and-control domains, exploit kit-compromised sites, and botnets. It can also boost performance while ensuring privacy.

    Quad9’s service uses threat intelligence from a variety of sources, including:

    • Cisco
    • F-Secure
    • Netlab
    • IBM X-Force
    • Anti-Phishing Working Group (APWG)

    Quad9 employs DNSSEC, which assures that the results supplied are accurate. It also filters out websites that have been categorized as hazardous using blacklists provided by various security suppliers.

    Quad9 supports DNS over TLS (DoT) and DNS over HTTPS (DoH). It’s been increasingly obvious in recent years that standard DNS has significant security flaws due to a lack of encryption. As a result, it is more susceptible to DNS hijacking. Quad9 users are effectively protected from cyber criminals as well as government censorship.

    The Quad9 service is run by the Quad9 Foundation, a non-profit organization based in Switzerland whose purpose is to make the internet a safer and more reliable place for everyone.

    Quad9 Features

    Quad9 has many valuable key features. Some of the most useful ones include:

    • Privacy: Quad9 is the custodian of a worldwide DNS infrastructure that allows people to communicate and participate in governance and civil society more easily. Quad9 protects their users' privacy by not collecting personal data; Quad9 protects their consumers' privacy by preventing connections between their devices and harmful Internet sites. Quad9 provides users with performance by placing servers in hundreds of communities all over the world to deliver service on a local level. Because of their non-commercial position, they are able to give equal emphasis to regions that are otherwise underserved.
    • Addresses: Quad9 offers a number of distinct recursive DNS service options. Each has its own IP address (or, in certain situations, hostname), which you may use to configure your devices.
    • Threat blocking: Both commercial and publically available threat intelligence feeds have been merged by Quad9. Each was picked based on its shown ability to identify threats and provide a comprehensive set of capabilities for detecting exploits, malware, ransomware, spyware, and other potentially hazardous websites. Quad9’s threat intelligence (TI) partners provide us with data on feeds that are rapidly updated and dispersed as new domain-based risks emerge, and these domains or hosts are updated in their lists.
    • Locations: Quad9 systems are available in more than 150 places in 90 countries, with significant expansion planned. Quad9's servers are primarily positioned at internet exchange points, which are the locations with the highest concentration of interconnections within a typical network region.

    Reviews from Real Users

    Below are some reviews and helpful feedback written by Zscaler Internet Access users.

    A Service Manager at a construction company says, "There are a bunch of different capabilities that are valuable within the platform. We use quite a lot of them, but not everything. The ones that are most important to us are the URL Filtering and the application control. For our needs, the cloud-native proxy architecture is a very good solution. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."

    Owen N., Security Architect at Claro Enterprise Solutions, explains that the solution’s most valuable features include “The integration of the gateway that inspects all ports and protocols. So, there is threat prevention; The cloud sandbox; VNS security; Access control that will protect URL filtering and the cloud firewall; Data protection that will protect your gateway, like your CASB or your cloud DLP; The capabilities of this will point your traffic to Zscaler Cloud.”

    An Architecture Senior Manager at an insurance company mentions, "The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go." He also adds, “The solution provides quick access to cloud services, securing our data and allowing us to inspect all our traffic.”
