I found this list:
Should your enterprise seek out a free antivirus tool? What are the 10 best free antivirus products? How do they compare to endpoint security?
solutionsreview.com
I read somewhere that some free versions of AVs can only be used for non-commercial use.
You can probably try each one and see which one doesn't slow down the PCs.
To be honest the Quote stated about some AV-Scanners being for Home use only is partially correct.
Why?
Some AV Developers use different Engine versions for Home and Business solutions.
Reason?
These are especially important because of IT-Solutions for specific areas of business-software.
Example?
SAP, SAP Business One, Manufacturing Software, CAD and allots more... those are business-critical applications.
OK and that means what?
The SMB / SOHO / Ent. solutions of AV Products have exclusions build in or can be optimized for the business-solution required.
Performance or Protection?
The thing is both is hard to achieve since there is no baseline "per-se" - But as a business you are required to protect your systems as much as possible. (Perspective from a German Technical-Consultant) - Why is that? Here we have laws and specific insurance policies that require a company to be as technologically protected as possible otherwise the owner has to pay out of its own pocket. So to protect that investment in a company I suggest a complete solution. From the Network Side up to the Client.
What are you talking about and who are you?
I myself am a:
- Technical-Consultant
- Sophos Consultant / Engineer / Architect
- and more... do not want to get in to detail that much. ^^
So what is my final suggestion?
Take a look at Sophos XG Firewall in combination with Sophos Intercept X Advanced
What does that do?
The Firewall is your first line of defense with build in dual-scanner, https-inspection, IPS/IDS and lots more.. the main point is "Heartbeat" that communicates with your AV Sophos Intercept X Advanced an tells the Firewall if the system has been compromised! If so it can isolate that system from itself and other clients in the Network. The AV has a very unique Ransomware protection and detects encryption attempts as soon as it detects them - It will isolate itself - restore the encrypted files - give a report on how that process was executed and lots more...
If someone needs more details just PM me...
