The Webroot SecureAnywhere® client is so lightweight and effective due to our cloud-based architecture. The endpoint agent simply sends file data to the Webroot Intelligence Network and then receives back an immediate determination on whether the file is known good, bad, or undetermined. This reduction of on-device processing leads to improved system performance and eliminates the need for definition files to be stored on disk.
This means pain-free deployment, no maintenance, and more available memory on every endpoint. The install is only 700KB, and the full footprint on disk is 3-5MB. PassMark testing has found Webroot SecureAnywhere to be 98% smaller than the average endpoint antivirus client.
The Webroot SecureAnywhere® Agent is an ultra-light 700KB client designed for significantly better operational speed than other AV solutions.
On disk, it occupies less than 4MB* of space. During scanning, its RAM usage is around 12MB*or less. It is by far the world’s lightest, smallest and most efficient endpoint protection Agent.1
Webroot succeeds where other solutions have failed, with a smaller footprint and faster scanning. It’s an easy-to-manage, time-saving product.
The Webroot SecureAnywhere Agent works by sending file signatures and ancillary data on programs and objects to the Webroot® Intelligence Network™. It then receives real-time predictions and determinations on whether an object is ‘known’ good, ‘known’ bad, or unknown/undetermined.
The reduction of on-device processing directly contributed to Webroot SecureAnywhere scoring a record 78/80, or 97.5%, in independent performance testing. These tests focused on different performance metrics determined by PassMark Software and compare Webroot SecureAnywhere to seven of the world’s leading AV vendors.
Webroot SecureAnywhere uses a variety of techniques to reduce the impact it has upon local endpoint resources. These include parsing the disk at the RAW level (to maximize scan speeds), minimizing network communication and intelligently tuning its memory usage when resource-intensive applications are detected. This feature is especially useful in traditional and virtualized server environments as well as on PCs.
During the most comprehensive scans, Webroot SecureAnywhere typically sends between 300KB and 2MB of data to the Webroot Intelligence Network for analysis. It normally receives back less than 250KB of data. On average, normal daily operation of the Webroot SecureAnywhere Agent exchanges less than 100KB of data with the Webroot Intelligence Network.
The result of optimizing Agent size, functionality, scanning, communications and interoperability within the endpoint environment is that it’s never obvious to end users that the program is using any CPU or RAM resources, and therefore never gets in their way.
Such low resource usage also permits Webroot SecureAnywhere to run concurrent scans, or effortlessly scale and run on virtual machines operating within a single physical server - without any disruption.
This low system impact also improves security, as Administrators may schedule regular security scans during the working day without impacting a user’s ability to keep using their machine; something not achievable with other solutions.
With the Webroot SecureAnywhere® Agent, there are no local signature definition updates, so user productivity is never impacted by recurring updates.
Our light impact on system resources also means that Administrators can schedule regular security scans during the working day without impacting the user’s ability to use their machine; something that’s impossible with most other solutions.
Definition Updates ‘In the cloud’
Usually, there is a lot of management involved but this is much simpler. Now, it’s just automatic.
Webroot SecureAnywhere maintains all threat updates at the cloud level within the Webroot® Intelligence Network™, so every Webroot SecureAnywhere user world-wide is instantly protected at exactly the same time.
This collective approach has several substantial benefits that turn into significant cost savings in person-hours, hardware, software and bandwidth.
Most importantly from a prevention and compliance perspective, every user is continually up-to-date when they are connected to the Internet and at the greatest risk. However, separately configurable Offline policies ensure they are fully protected when offline too.
There are now no operational risks such as ’blue screens’ due to a corrupt definition updated and the unplanned compatibility changes they may produce. Network bandwidth is also minimized, as there is no longer the need to distribute large definition update files that can consume 5MB+ per day. Plus, IT saves time thanks to never having to test and administer new updates. There is also no need to maintain or pay for any on-premise servers dedicated to AV signature definitions.
Eliminating definition updates represents a huge advance in the design of antivirus technology and one that is unique to Webroot SecureAnywhere.
