Conclusion:
When it comes to cybersecurity, waiting until something breaks is the worst plan. That’s why these incident response companies are such a big deal. They help you stay one step ahead-or at least stop things from going completely off the rails when a breach happens. Whether you’re a small company or a big one, having a team that knows what to do during a crisis is a lifesaver. And honestly, if you don’t have some kind of response plan already in place, now’s probably a good time to fix that. Better to deal with it before things go sideways than try to pick up the pieces after.
