Yes, Bitdefender is freely selling variety of SDKs for everyone who’s willing to use them. These SDKs extend far beyond the anti-malware engine, vendors can license and integrate all SDKs they deem appropriate.
Antimalware endpoint protection OEM technology (software development kit - SDK), is now available for integration with your business security products or services.

All SDKs relevant to protecting home user, including Advanced Threat Defence, Anti-Spam, anti-malware, web-filtering are included in Vipre. They are combined with proprietary firewall (not offered by Bitdefender as an SDK). Even the Photon (whitelisting and caching) is included in Vipre under the name Vipre Rapid Scan (tm).
It’s just some components are better configured such as the web filtering (slightly more aggressive) as well as the firewall which out of the box blocks a lot more unneeded connections. Vipre has one of the best firewalls I’ve personally seen. In addition, the product is not difficult to use at all, not over-complicated and not bloated. All in all, seems like a great choice also passing the “girlfriend test”.
