Data comes in the form of emails, bank details, medical details, manufacturing processes, staff bank details, in fact, any information available about your business, your staff and your clients.
How well could your business cope if that detail became unavailable due to being encrypted by ransomware? How valuable would that data be to cyber-criminals if it was breached?
How likely are your clients to trust you again or recommend you if their data had been breached because you had not implemented robust security systems?
Without adequate security systems, not only is your data at risk but so is your reputation and potentially your entire business.
