sorry, dear forum, I still just another question too.
Which scan engine does F-Secure use? Is it Bitdefender + 's own or did F-Secure develop its own scan engine?
I ask out of interest. Thank you very much for your effort.
Sorry for my reply. I am only an F-Secure user (their home solutions).
Current F-Secure solutions (at least, most of them) are not about mentioned 'scanning' engine / platform. If you ask, who is it now? Well, take a look at the leaderboards for detection and overall engine quality in independent reports and tests. For example, the one created by Avira is fine. :)
But it should be noted that in any case - the "main" (traditional) engine is not the only one in the multi-layered protection provided by F-Secure. So, even if a certain engine/core is based on 'third party' ones - F-Secure maintain it anyway and build some tweaks around it. Kind of traditional (signature-based and advanced one techniques) is called F-Secure Capricorn. Previous engines was "F-Secure Aquarius". Both are based on the industry-leading scanning platform at the time. However, this is just a tool that any company can use (including its own development company). Because of this, there may be differences (often small or negligible) in implementation or capabilities. That is, for example, signature detection will be more often at the same level. And the rest may depend on the circumstances despite the one main core.
F-Secure SAFE also has some other engines that cover some specific detection techniques or add additional ways to combat threats.
In addition, quite powerful and own (at least, was) F-Secure engine is "cloud one". It is also expanded view of their Ultralight design.
Another cool thing is F-Secure DeepGuard. You could read about these technologies and realizations there: https://blog.f-secure.com/whitepapers/
For example, whitepapers: "F-Secure Ultralight", "F-Secure Security Cloud", "F-Secure DeepGuard" (3rd edition). I think they should provide comprehensive information.
// In general, I mean that F-Secure has created a long time ago, let's say, an "engine" that allows you to use different "cores" at once. Including scanning. Therefore, F-Secure solutions can detect a treat based on multiple engines. And use them for scanning.
But the answer to your question is only the first paragraph of my reply.
