Please trace where the cybersecurity requirement comes from. The answer is usually either a contract with a "special" customer whose industry is affected by regulations and who must pass these requirements onto contractors, or the fact that regulations apply to your company directly.

If you can trace it to a particular unusual customer, be vocal about the consequences. If it is due to regulations, sorry, there is nothing you can do. Otherwise, if there is no external reason for the "security" tightening, complain to the person who made this wrong decision and to his manager.

In any case, giving you the tools that are necessary for your work (and by "work", I mean not just being a glorified messenger), like a separate test environment, must be a priority for your manager, even if those tools cost 100000 USD.
