Transition to Proprietary Signatureless AI Engine for Next-Gen Threat Detection

ahmedmohamed

Dear F-Secure Team,

I would like to propose an important enhancement to your product strategy. Currently, relying on OEM engines such as Avira may limit both scalability and long-term innovation. Instead, I suggest that F-Secure develop its own proprietary AI-driven, signatureless detection engine.

This engine would operate similarly to next-gen solutions like SentinelOne, CrowdStrike Falcon, or Arctic Wolf, which are not dependent on traditional signature databases but leverage machine learning, behavioral analysis, and real-time threat intelligence.

Moreover, building this engine in partnership with such next-gen vendors could accelerate development, strengthen detection capabilities, and significantly reduce licensing costs associated with third-party engines.

This strategy would help F-Secure:

• Create a unique, future-proof competitive edge
• Improve detection accuracy and speed
• Provide customers with a lightweight, cost-effective, and more powerful security solution
• Enhance brand independence from OEM vendors

I strongly believe this approach could transform F-Secure’s positioning in the cybersecurity market.

Best regards,

next-gen solutions like SentinelOne, CrowdStrike Falcon, or Arctic Wolf

I am not very familiar with these solutions, but are they something similar to WithSecure's things like Broad Context Detections, Luminen and other parts of Elements platform, as well as some old stuff like their DeepGuard and Ultralight things?

If so, in the view of your feature request - should F-Secure invent something 'of its own' or partner with WithSecure to somehow 'backport' it to home-users side? Something like a collaboration after demerger?

If 'invent something of its own' - perhaps - it should be already a bit of more next-next-gen solution now.

You might want to take a closer look at the technologies behind SentinelOne, CrowdStrike Falcon, and Arctic Wolf. That way, you’ll see more clearly what I mean — especially regarding static AI detection and machine learning approaches that are purely signatureless, not hybrid models mixing signatures with AI.

Yes, maybe. I only have a general idea about them.

And since they were originally mentioned specifically (and as next-gen solutions), it was not entirely clear to me how to fit this into the landscape of home users, unless perhaps to make some kind of next next-gen design, taking into account the use of approaches that have already long been used in much of the industry.

So, looking at the technologies behind is maybe a bit more thing to me (as I might have missed something). I mean, if the point of this feature request is not to reproduce exactly 'style' of "SentinelOne, CrowdStrike Falcon, and Arctic Wolf" solutions. Because, for example, there is no certainty that this would be enough, and also that the conditional "hybrid" things would not be relevant even today or tomorrow.

Anyway, sorry for the discussion. It would be good if F-Secure developers and official staff would evaluate it properly.

Thanks!

Hi,

An interesting idea came up in the discussion: F-Secure could develop its own fully signatureless AI-based detection engine. The motivation behind this is to reduce reliance on external OEM engines (like Avira), improve detection accuracy and speed, and cut licensing costs. The model would be closer to so-called next-gen solutions such as SentinelOne and CrowdStrike Falcon, which rely purely on AI, machine learning, and behavioral analysis rather than signature databases.

On the other hand, F-Secure and WithSecure already have advanced hybrid technologies in place (DeepGuard, Ultralight, Broad Context Detections, Luminen). Maybe these could be brought more broadly to the consumer side instead of starting from scratch with a completely new engine.

So, the way forward could be seen in two possible directions:

1. invest in developing a fully signatureless proprietary AI engine, or
2. strengthen and expand the existing hybrid solutions to home users.

It would be great to hear which approach F-Secure considers more realistic and strategically sound for the future. "

I I know that the topic requires further study from F-Secure, but the future is moving towards signatureless next-gen AV. It could be adopted by both F-Secure and WithSecure. In fact, if implemented, they would be the first company to provide this technology to home users.

It’s also very possible to use multiple engines along with static AI, and the company could release beta versions to test the solution. The process is not easy, but in the end, the engine would become much stronger.
