If you have been evaluating business class antivirus solutions you have undoubtedly come across the decision to choose between a cloud solution or an on-premise solution. Let’s discuss the difference between them and learn the pros and cons so you can make the educated choice that is right for you.
A cloud solution can also be referred to as a “hosted” solution or “software-as-a-service” (SaaS). Cloud options have become much more robust in the last few years. The fact is, most providers would prefer that you select their cloud option. That being said, it’s not always the right way to go.
Pros:
-Cloud solutions usually use less resources (lighter footprint). This can prevent slowing down your computers keeping everyone more productive. Instead of downloading the software onto each computer, an agent (small file) is installed. This file contains information that will connect your computer to the host. It can also store other information that will assist in the licensing and scanning of your machine.
-A cloud solution will have a browser console. This will allow the administrator to access the admin console from anywhere with an internet connection and manage the antivirus on their computers remotely.
-Deployment is not restricted to the local network and can be delivered by email. Many companies have multiple locations and home office environments. As long as the agent is installed on the computer, the computer can be anywhere. When the computer is connected to the internet, it will have the most recent updates available and be visible on the admin console.
-Cloud solutions will have real-time updates. On-premise solutions require that each computer download the latest signature files, patches, and even latest versions, whereas, the cloud products will always be running with the latest everything.
-Cloud solutions are licensed as a subscription rather than a perpetual license. As long as your subscription is up to date, you are protected with the latest version of the software. This can also allow for more payment options. Some providers will offer monthly payments and allow you to add or remove licenses on the fly, so you are never without protection and you are never paying for licenses that are no longer necessary. NOTE: Some may think it’s better to own the software perpetually. Understand that you only own the software up to the last update when the license expires. Sure, it will continue scanning, but updates are happening regularly, sometimes multiple times a day. An expired perpetual license will not protect against new and emerging threats.
-Most providers are investing more into their cloud solutions, especially for smaller businesses. You may be granted more access to the latest and greatest technologies as an incentive to select their cloud option.
Cons:
-Cloud solutions may not have as many features that mid and enterprise level business may need. The cloud solutions that do offer a more robust feature set often lose the "light weight" advantage of being a cloud solution.
-Subscriptions historically can cost a little more because you are paying the same every year rather than a lower cost maintenance fee.
-Protection ceases if you allow the license to expire. There are no files on your computer to keep scanning. Again, the perpetual model doesn't really offer much more given the frequency of updates that occur.
-Cloud browsers are considered to be less secure, so it is vital to use strong passwords and multi-factor authentication to prevent unauthorized access.
-An Internet connection is required to continue scanning with the latest updates. Some agents store enough information to keep scanning without an internet connection. There are a few solutions that require the connection to scan. This can be an issue for those who travel with a laptop. For example, they may insert a USB drive while not connected. If the USB drive is infected, then the computer is at risk.
My recommendation for small to medium size businesses is to opt for the cloud solution. First, these products are often designed for businesses up to 1000 users and offer the added security of real time updates. Second, the ability to deploy to computers outside of the local network (remote locations and home offices) provide flexibility not readily available with on-premise products. Third, the central admin console is accessible with any internet connection and allows for administrators to manage the solution without being onsite. This adds an additional benefit of securing the physical office by reducing the need for after hours access in case of an alert.
The solution you choose needs to fit your specific business needs. Consider your unique requirements and decide on the features you need to meet them. Your business need should drive your decision rather than the convenience factor or cost. Antivirus isn’t one-size-fits-all . Though the different antivirus solutions are basically similar in nature, each offers a unique edge.
