Regardless of the network security systems your company has in place, it is a matter of “when” rather than “if” a hack occurs. Responding quickly after a breach is critical to minimise the damage that can be done. The sooner you are aware of a data breach, the sooner you can plug the hole.
Using an intrusion detection service will not only alert you when the network has been compromised, but it will collect invaluable data your business can use to protect itself from future intrusions.
Furthermore, these solutions incorporate sophisticated threat detection algorithms that detect any untoward actions from employees, especially those who might have become disgruntled with the organisation and are looking to steal or compromise data.
