Cloud edge security software provides enterprises with a cloud-delivered solution to securely access the internet and cloud-based applications that run at the cloud edge or where compute capabilities are run closer to end devices. The software is delivered using software-defined wide area network (SD-WAN) technology. This allows cloud edge security solutions to operate anywhere and combine security functions to protect all network activity.
To address the need for cloud edge security software, many organizations are turning to secure access service edge (SASE) platforms, which converge SD-WAN capabilities with network security functions as a cloud-delivered service.
SASE framework: The SASE framework includes capabilities such as cloud access security broker (CASB) software, zero-trust networking software, and firewall as a service (FWaaS) —all available in a single cloud-delivered service model that simplifies IT.
SASE architecture: SASE architecture also enables companies to return networking and security to the cloud where the applications and data are located. It helps ensure secure access regardless of device location. It provides a set of best practices to secure applications and data in an era where work happens everywhere, and users are the new network perimeter.
There are several benefits to using cloud edge security software, as mentioned below.
Secures data: A major advantage of cloud edge security platforms is that it helps secure the data already being processed at the cloud edge. The sheer volume of data produced by devices at the edge connecting to the internet requires vastly more processing.
Secures real-time transactions: Edge computing moves processing and storage resources closer to the source of cloud data to manage loads. However, the movement of data from the cloud to the edge makes it very vulnerable to attacks. Cloud edge security software helps secure real-time edge data transactions that might take place in the Internet of Things (IoT), such as smart applications in retail or manufacturing. These tools make these transactions more secure and reliable.
Secures endpoints: Examples of cloud edge security software capabilities include web filtering, anti-malware, intrusion prevention systems (IPS), and next-generation firewalls that permit or deny traffic based on IP addresses. These functionalities are often built into the organization's SD-WAN. Effective cloud edge security software enables IT to secure all edge endpoints or devices easily.
IT and cybersecurity staff: IT and cybersecurity staff use cloud edge security tools to securely monitor the data traffic at the cloud edge, ensuring safe B2C and B2B transactions. Securing these transactions keeps intruders from attacking these otherwise vulnerable internet transactions, which may be numerous in volume.
Industries: As enterprises move cloud capabilities across the WAN to users at the edge, industries such as healthcare and finance have more burden to protect sensitive data that comes with strict compliance requirements. Cloud edge security software can prioritize important security fundamentals such as encryption for data stored locally and in transit between the network core and edge computing devices.
There are some challenges IT teams can encounter with cloud edge security software.
Potential design flaws: With edge computing comes devices that can take virtually any form, from micro-data centers at remote locations, or a vast array of IoT devices. An example is the rapid shift to hybrid work models in response to the global pandemic, where millions of distributed remote offices and BYOD devices suddenly had to be managed simultaneously.
However, the design of these edge devices prioritizes functionality and connectivity over security. A poorly designed cloud edge security software approach by buyers does not secure the edge and makes it vulnerable to zero-day threats.
Increased cybersecurity risks: Edge computing increases the risk of cybersecurity threats entering the corporate network. Deploying hundreds of edge computing devices creates hundreds of potential entry points for security attacks and breaches. Cloud edge security solutions must have a 360-degree view of the attack surface and provide a built-in security stack to protect against zero-day threats, malware, and other vulnerabilities at the point of access.
If an organization is just starting and looking to purchase cloud edge security software, g2.com can help select the best one.
Most business pain points might be related to all the manual work that must be completed. If the company is large and has a lot of networks, data, or devices in its organization, it may need to shop for cloud edge security platforms that can grow with its organization. Users should think about the pain points in security to help create a checklist of criteria. Additionally, the buyer must determine the number of employees who will need to use the cloud edge security software and if they currently have the skills to administer it.
Taking a holistic overview of the business and identifying pain points can help the team springboard into creating a checklist of criteria. The checklist serves as a detailed guide that includes both necessary and nice-to-have features, including budget features, number of users, integrations, security staff skills, cloud or on-premises solutions, and more.
Depending on the deployment scope, it might be helpful to produce an RFI, a one-page list with a few bullet points describing what is needed from cloud edge security software.
Create a long list
Vendor evaluations are essential to the software buying process, from meeting the business functionality needs to implementation. For ease of comparison, after all demos are complete, it helps to prepare a consistent list of questions regarding specific needs and concerns to ask each vendor.
Create a short list
From the long list of vendors, it is helpful to narrow down the list of vendors and come up with a shorter list of contenders, preferably no more than three to five. With this list, businesses can produce a matrix to compare the features and pricing of the various solutions.
Conduct demos
To ensure the comparison is comprehensive, the user should demo each solution on the short list with the same use cases. This will allow the business to evaluate like for like and see how each vendor stacks up against the competition.
Choose a selection team
Before getting started, creating a winning team that will work together throughout the entire process, from identifying pain points to implementation, is crucial. The software selection team should consist of organization members with the right interest, skills, and time to participate in this process. A good starting point is to aim for three to five people who fill roles such as the main decision maker, project manager, process owner, system owner, or staffing subject matter expert, as well as a technical lead, head administrator, or security administrator. The vendor selection team may be smaller in smaller companies, with fewer participants multitasking and taking on more responsibilities.
Compare notes
The selection team should compare notes, facts, and figures noted during the process, such as costs, security capabilities, and alert and incident response times.
Negotiation
Just because something is written on a company’s pricing page does not mean it's final. It is crucial to open up a conversation regarding pricing and licensing. For example, the vendor may be willing to give a discount for multi-year contracts or for recommending the product to others.
Final decision
After this stage, and before going all in, it is recommended to roll out a test run or pilot program to test adoption with a small sample size of users. If the tool is well used and well received, the buyer can be confident that the selection was correct. If not, it might be time to go back to the drawing board.
Cloud edge security software is considered a long-term investment. This means there must be a careful evaluation of vendors, and the software should be tailored to each organization's specific requirements. Once cloud edge security software is purchased, deployed, and integrated into an organization’s security system, the cost could be high, so the evaluation stage of selecting the right tool is crucial. The notion of rip-and-replace cost can be high. The cloud edge security software vendor chosen should continue to provide support for the platform with flexibility and open integration. Pricing can be pay-as-you-go, and costs may also vary depending if cloud edge security is self-managed or fully managed.
Organizations decide to purchase cloud edge security software with some type of return on investment (ROI). As they want to recoup the money spent on the software, it is critical to understand the costs that will be saved in terms of efficiency. In the long run, the investment must be worth preventing the downtime and loss of revenue that would be caused by a security breach.
