A real desktop computer in a nice office.
A real laptop computer to share ideas on, walk around with.
A secure internal network to store work well away from the outside world.
A computer to search the web and use social media on that is not work connected, an entire different physical network.
If staff have to travel to other nations give them a brand new work phone and new laptop. Trendy looking but consumer grade.
The only contact is their boss and legal support. The computer device only has a few productivity apps for global meetings.
Do not allow any extra company data to move out of your nation with the worker.
Have staff meet their international contacts face to face in a secure setting, no smartphones, IoT around them. Use paper for vital information not a laptop file with all the brands secrets.
The worker does not return to your nation with any new data.
Be aware any nation can get access to that device globally so it could bring back issues that can a pass any reinstall. Dont trust any company device after it has been outside your own nation.
Make sure staff have all the documents for the language of systems they are using. If its close source, buy the full support.
If open source, download it all off site and keep an internal database updated for searches and issues.
That will stop interesting searches by staff on the web showing what your brand is working on.
Dont just give away your designs, new work everyday with complex search terms.
Expect your internet and other networks to be of interest to competitors, random people on the net, cults, faith groups, other private brands, governments and their security services, former mil/gov workers now in the private sector.
If its really vital, use secure paper files and a secure vault for meetings. No smart phones, smart devices, IoT allowed.
Read up on what the NSA, CIA, GCHQ can do to networks, to devices physically and on networks.
All the software and hardware issues gov/mil contractors can offer the private sector for the right price.
Be aware of buying new devices online and having them shipped in.
Alternation might be passible on the way. Crypto junk fresh out of the box as installed.
Educate staff on approaches by random strangers, new friends with interesting questions about work, who could have had contact with smartphones, laptops outside of work.
Make sure staff have full 24 hour legal and security support to report any efforts to ask about work, security at work.
Dont bring malware into work via random devices found. Dont allow "new friends" to just wonder around secure work areas to physically place malware or collect the results of past malware.
Do to allow any random sales reps to wonder around work. It could be an effort to map the building and place malware or collect data.
With your data more secure, a brand can then bring new products and services to the market without having their own gov, other governments, security services or competitors interfering with new products. Protect your brand, your staff, your ideas and bring new products to market.
Always hire staff on merit, do interviews and look at their entire background.
Look at their university life, are they smart or did they always need help from smart people around them?
Good workers can work, they don't need constant help or advice when given work. If staff have few skills find out why they slipped past the complex interviews? Inside help? If they have few real skills, what else is fake about them and why are they working for you?
Secure the interview system and do more background work on everyone why wants a job with your brand. Do not trust any of their paperwork or stories, look at every detail and see what is true.
Once only good workers are allowed in most of the issues are with expected brand products, marketplace not unskilled staff. Only hire on merit and make sure the skills listed are real.
Staff should be working for your band, your brand should not be working to help staff with their lack of skills.
Secure your ideas, only hire good workers, support your workers, don't hire workers that cant work.
