"An ounce of prevention is worth a pound of cure." said Benjamin Franklin in 1736 as he was trying to advise his fellow Philadelphians to implement the impressive fire prevention measures he had seen put into place in Boston.
And so here we also beseech you to take preventative measures. We've had multiple companies come to us to fix hacked websites, hacked email accounts and lost data. Believe me, you take these things for granted until they're gone.
Don't believe you're immune because you're just a small or medium enterprise, or in a niche industry no one cares about, or aren't very public-facing. Hackers take advantage of complacency, and know that companies that think they're off the radar can be guilty of it and hence easy targets. Not to mention a lot of hacking is automated, so their scripts come after you no matter who you are.
