Home officces may very well be more secure than actual offices
If you follow proper data handling procedures, you have much less risk with a home than a rented office building. A home is going to have a very small number of people coming and going and even fewer people with access to the systems.
Including myself, only three people have access to my home, and I know them extremely well. I do my work in a dedicated home office that has its door closed at all times (mostly for keeping the temperature consistent), and to get to it, you have to pass through my bedroom. While, with the office my employer issued me, there are literally hundreds of other people that have access to it in addition the dozens of cleaning and maintenance staff.
On the networking level, my office has its own Internet connection, which goes through a firewall that allows nothing in and does a lot of filtering on stuff going out. I can verify my network hasn't been tampered with since its a very basic layout with each of the 4 computers in that room being connected right to the backside of the firewall / router. Since its all my own traffic, there is very little that needs to be allowed, and I can heavily filter the stuff that is allowed. While my workplace network has to deal with everyone's traffic, devices being added and removed on a daily basis, not to mention how permissive the network needs to be to handle the wide variety of needs for the other projects operating. And I don't have to worry about some PHB downloading a bit of malware and infecting the whole network.
