Sophos Antivirus for vShield trounces the competition

Server ProtectionA new report by the Tolly Group found that Sophos Antivirus for vShield “consistently outperformed Trend Micro Deep Security 9 and McAfee MOVE” in virtual server and virtual desktop (VDI) environments.

Sophos Antivirus for vShield provides centralized, agentless antivirus scanning for virtual machines (VMs) running on VMware’s ESXi hypervisor. It’s natural that an agentless solution would outperform traditional endpoint antivirus products, which have to be installed and run in parallel on each virtual machine. But, as it turns out, even agentless scanners vary quite a bit in their impact on VM and host resource use and performance.

How to protect your virtual machines from malware, without hurting performance

Virtual-machinesVirtual machines — whether running on VMware ESXi, Citrix Xen, or Microsoft Hyper-V — create an interesting security challenge. On one hand, they’re every bit as susceptible to malware and other threats as conventional systems. On the other hand, traditional antivirus software doesn’t always play nicely with dynamic, highly consolidated virtual environments.

In particular, the overhead of running multiple concurrent antivirus scanners on a single host can affect performance and scalability. Meanwhile, the constant starting, stopping, and cloning of virtual machines can leave systems unprotected.

A new Sophos whitepaper explores these challenges and presents two effective approaches to securing your virtual machines without sacrificing performance: agentless antivirus and virtualization-optimized endpoint security.

Do you need antivirus on your Linux servers?

Server ProtectionLinux servers come in many flavors, from Red Hat to SUSE to Ubuntu. All share a common reputation as being largely immune from the malware problems that plague Windows. It’s no surprise, then, that many IT professionals wonder whether it’s really worth installing antivirus software on their Linux servers. As it turns out, the answer, more often than not, is yes.

One reason to consider installing Linux antivirus is that malware for Linux does, in fact, exist. It’s far less common “in the wild” than Windows malware, but rootkits like the one that targeted the SSHD daemon earlier this year demonstrate that it is a real threat. Do you want to explain to the boss that a mission-critical server got trashed because you didn’t think it was likely to get infected?
