How many of you have managed critical infrastructure in your life? None.
Have you any experience running systems for a large multi-national financial institutions/banks? None.
What about working in a university or protecting a major oil company in the Middle-East? No you haven't.
Your seriously telling people you can protect Windows systems in those situations I listed with only in built Windows tools? Seriously?
That day may come in about 25 years when you only need Windows in built tools but in today's climate you still need other vendors security tools to keep malware free.
In my early years 2011 , i worked in a school (200+ machines) and help the IT manager/admin which is also an IT teacher and ex-NASA, guess what ? no 3rd party security apps were used. Only Win7 Ent with Applocker/SRP/group policy and Norton Ghost (as fail-safe) and still now, they upgraded to Win10 Enterprise and are very happy with it, and yes still not using 3rd party softs.
I knew an Chief IT who fought his CEO to remove a 3rd party famous vendor because the softwares caused more issues than good on his networks.
Big Corporations don't use Win10 Home, they use Win10 Enterprise; where you get Group Policy, Applocker and an arsenal of security features designed to lock employees' workstation nullifying the need of 3rd party vendors softwares.
Symantec and Sophos are those "popular vendors who emerge not because their software solutions but for their hardware-based solutions.
Those huge corporations are focused on securing their networks with hardware (Hardware FW , honeypots, virtualized servers, etc...) not softwares and even less Kasperky or BD lol.
Huge corporations dont use classic vendors, they have tailor-made softs from vendors mostly unknown to the general public.
One example is Blue Ridge Network, many government agencies in US are using a tailored version of Appguard.
Saying you should only use Windows tools and using any 3rd party tools are for the super paranoid is bad advice. Telling people to uninstall Kaspersky or Norton or Bitdefender and stop being paranoid and only rely on Windows will only result in more malware infections not less.
who said that? We say to every users
"keep the native security and if you
still feel
unsecure, add whatever you want , but most important , have
safe habits"
the idea of relying primarily on native windows security features is for educated and cautious home users who don't have special needs.
The corporate situations you mentioned will have to use a more sophisticated solution, as you said.
Exact , we are in a Home user forum. not a corporate-oriented one.
