"Is this how it's like at all large companies?" Short answer is probably yes. Depending on where you are located, but with large corps you may end up with SOX among other things.

Over time all the tools will fine tune to all the new processes and the overhead will hopefully be reduced. If there is ambition for this.

Also, have in mind that many large security breaches happens when large corporations acquisition smaller companies and tries to incorporate them too fast.

Do not be too quick to switch job is my general advice.
