What is Ransomware?
Ransomware is becoming more and more of a major threat to businesses, it is impacting all types and sizes. Ransomware is a type of malicious software designed to block access to your files, data or computer until a sum of money is paid. Distributed in a variety of ways and is difficult to protect against as it’s constantly evolving.

Protect your business against Ransomware
A ransomware protection strategy requires a three-way approach – education, security, backup
User education is a powerful way to protect your business. It is critical your team understands ransomware and the threats it poses. Make sure they are able to recognise suspicious websites and emails and if they come across a potential threat they know what to do.
Antivirus is key and you should ensure it is always up to date in order to protect you from newly identified threats, some offer ransomware specific functionality. Minimise vulnerabilities in your system by keeping all business applications patched and updated.
It’s essential your business has a robust incremental backup strategy in place. If you suffer a ransomware attack, this will allow you to roll-back your data to a point- in-time before it happened and you will not need to pay the ransom. It is also a good idea to keep several copies – offsite & cloud.
