A dedicated security website/blog for Norton

Nabeel Mansoor:

Yes, I have come across this blog however as I mentioned it lacks latest threats and security update news unlike Securelist.com - Hope Norton would take this up as it would be of great benefit.

I got your point. You may refer to the Protection Bulletins and Symantec Blogs published by Broadcom. They are regularly updated on weekdays. 

NortonLifeLock (formerly Symantec) sold its virus research department to Broadcom and Norton's engine is currently maintained by Broadcom.

Nabeel Mansoor:

Thanks Anthony. Your reply was indeed enlightening. So with Broadcomm buying Symantec Enterprise business, Norton Security does not own or possess their own virus research department but rather depends upon a 3rd party?

Sadly, yes, according to the SEC filing. 

We are dependent upon Broadcom for certain engineering and threat response services, which are critical to our products and business. We could lose our access to these or other data sources, including threat intelligence, which could cause us competitive harm and have a material adverse effect on our business, operating results, and financial condition.
Our endpoint security solution has historically relied upon certain threat analytics software engines and other software (the Engine-Related Services) that have been developed and provided by engineering teams that have transferred to Broadcom as part of the Broadcom sale. The technology, including source code, at issue is shared, and pursuant to the terms of the Broadcom sale, we retain rights to use, modify, enhance and create derivative works from such technology. Broadcom has committed to provide these Engine-Related Services under a transition services agreement, substantially to the same extent and in substantially the same manner, as has been historically provided. As a result, we are dependent on Broadcom for services and technology that are critical to our business, and if Broadcom fails to deliver these Engine-Related Services it would result in significant business disruption, and our business and operating results and financial condition could be materially and adversely affected. Furthermore, we cannot provide assurance that we will be able to obtain data from alternative or additional sources if our current sources become unavailable, and if we are able to obtain alternative sources, we could be unable to integrate or deploy them in time, which could cause us competitive harm and have a material adverse effect on our business. Additionally, in connection with the Broadcom sale, we lost many industry-specific engineers and other capabilities, including certain threat intelligence data which were historically provided by our former Enterprise Security business, the lack of which could have a negative impact on our business and products.
