At CNS we understand the critical importance of safeguarding your SME against ransomware attacks. As your trusted IT partner, our primary goal is to ensure that your organisation remains resilient in the face of evolving cybersecurity threats. This guide outlines our expert advice and guidance on protecting your business from ransomware, as well as explaining how CNS can help you defend against malware attacks.


Understanding Ransomware

What Is Ransomware?

Ransomware is a malicious software that encrypts your valuable data, making it inaccessible. Cybercriminals then demand a ransom for the decryption key. Unfortunately, paying the ransom is not a guaranteed solution and can exacerbate the problem.


Why Are SMEs Vulnerable?

SMEs are increasingly targeted by ransomware attacks for several reasons:

Limited Resources: SMEs often lack the in-house expertise and budget necessary for comprehensive cybersecurity.

Lack of Awareness: Many SMEs underestimate the severity of the ransomware threat and thus fail to prepare adequately.

Easy Targets: Cybercriminals view SMEs as lucrative targets, as they are less likely to have robust security measures in place.

A good managed service provider should assist you in implementing robust protection strategies:
