Well, can't tell about the freebies, but F-Secure has been global in the Endpoint protection market for ages. As far as I know, they aren't an OEM of any of those on the list.
For clarity, I don't sell any software whatsoever. I just install what my customers want and if asked tell them what I like or dislike. Knowing how big F-Secure has grown in Europe it feels odd that they're not on the chart.
Read my lips... F-Secure do not do any Advanced Endpoint Protection products. They only do traditional AV, which in laymans terms is FUBAR. What you're asking is "Hey why isn't Fred Johnsons Horse Drawn Buggys tested in Supercar Magazine?".
AEP aka Next Gen AV does stuff like Cloud based sandbox/AI/Machine Learning as well as a huge raft of non-signature based analysis. So when a previously unseen piece of malware lands it will shut it down.
I put Cylance through some testing a few years back and had impressive results with it (including defeating two genuine malware attempts that the signature based stuff didn't have protection for for up to 6 weeks). I did check f-secures product page and they didn't not have any of this capability.
For clarity I don't sell software either. I work in government as an internal security consultant.
Also there is a 30 day trial, feel free to give it a spin. If I put money down for it is that not a decent recommendation?
