Review: Cisco Umbrella Offers Full-Coverage Cloud Security

Protect your users from internet-based attacks with this enterprise platform.

Education leaders have taken a strong stance on preventing cyberattacks, especially with so many users learning and working from home during the pandemic.

Attackers have taken advantage of the recent chaos, launching more attacks than ever. Even before the pandemic, ransomware attacks on K–12 schools had become increasingly common. In 2021, more than a thousand schools fell victim to ransomware attacks, according to a January 2022 Emsisoft report.

Cybercriminals have grown more sophisticated with their ransomware attacks, but paying the ransom doesn’t guarantee data will be returned. The best defense is always to prevent the attack in the first place.

To that end, there is Cisco Umbrella. The software can help school districts protect their networks by blocking traffic at a Domain Name System level, which ensures contact with an infected website is halted.

Simple to Manage Security for K–12 IT Teams

Umbrella is a cloud-based security platform, which makes it simpler to implement and maintain than most other enterprise solutions. For school districts with multiple sites, the entire platform can be managed from the cloud. The interface is also user-friendly. Some technical knowledge is required, but you don’t have to be a top-level expert to manage Umbrella.

An Improved Version of the Cyber Tool

Several years ago, Cisco rebranded OpenDNS enterprise security products as Cisco Umbrella. Having reviewed the solution before as OpenDNS, and now as Umbrella, I was surprised by how it remains one of the most comprehensive security solutions for schools to administer, even as it adds new features, such as cloud-based deployment and management and an improved user interface.

More important, the easy deployment of the solution and its simplicity to manage remain intact, placing it among the most crucial tools for keeping school networks safe. Also, by providing this solution in a cloud-delivered security architecture, Cisco adds the ability to provide security that scales with any changes to the academic environment. It’s no longer a problem to add students, classes or even whole campuses and expand protection.

MORE CLOUD SECURITY: These tools secure today's cloud environments in K–12 districts.

Another improvement is that Umbrella requires little maintenance after setting up the initial configuration and policies. It’s intuitively built to do most of the heavy lifting itself with little to no human intervention. Just under 10 minutes after configuration, Umbrella will be protecting any devices with access to a school’s internet.

My favorite feature on the new Umbrella-branded platform is the dashboard, which allows administrators to view the threats Umbrella has thwarted and where those attacks were trying to land. You do not need an advanced degree to understand what is happening in terms of security. You get real-time access to a host of information about your network’s security posture right from the main interface.

Just like its older versions, Umbrella makes it simple to view and modify your threat protection. Users can even submit their own requests to the administrator to review a site they want unblocked or something they think might be suspicious, making security more of a community endeavor.

Before the Umbrella branding, most of the OpenDNS tools that folded into this platform were highly accurate, but they weren’t always easy to use. You could also run into problems trying to monitor all of them at the same time. By folding everything under Umbrella and improving the interface, Cisco has created a security product that is much more than the sum of its parts. That’s just what busy school IT professionals need in this increasingly hostile threat environment.

Cisco Umbrella is Robust, Scalable and Comprehensive


Simplified Threat Hunting Within a School's Network

By drilling down on data collected by Umbrella, network administrators can identify and restrict access to websites based on the needs of the institution.

The Investigate feature also simplifies threat hunting within a school’s network. When conducting threat hunting, Umbrella provides network administrators with critical information, such as IP addresses, domains and malware hashes. It’s an impressive tool for veteran threat hunters. Additionally, Umbrella has three striking features. First, Cisco provides a high number of predefined lists that are constantly updated for effectiveness, which can help school districts reduce overall costs.

Second, Umbrella empowers IT security teams with a platform that effectively blocks malware and phishing attempts from the web. This could allow schools to eliminate and consolidate some of their other security tools.

Finally, Cisco Umbrella provides real-time monitoring on all network devices, including roaming users within the network. This ensures that everyone operating a device on a school’s network is safely navigating the internet and remains protected.
