Cyberattacks are becoming more frequent and sophisticated, and SMEs are particularly vulnerable.

The cost of a cyberattack for an SME can be considerable. According to a study conducted by the Ponemon Institute, the average cost of a cyberattack is $2.2 million. This figure includes direct and indirect costs of the attack, such as lost revenue, costs to repair IT systems and damage to the company’s reputation.

This is today a major issue for our companies, particularly for innovative companies.

Business leaders must therefore prepare for a cyberattack and prevent potential devastating consequences for their business.

Indeed, a cyberattack can result in the loss of sensitive data, business interruption, loss of customers and revenue, and even business bankruptcy .

Here are some tips to help you anticipate a cyberattack:

Computer hygiene is the set of good practices that help protect your computer system against cyberattacks.
These practices are simple and basic, but they are essential to limit the risks of hacking, data theft or the spread of viruses.

The main rules are as follows:

  • Protect your devices: It’s important to have up-to-date antivirus and firewall software, and configure them correctly. It is also recommended to regularly update your software and operating system.
  • Secure your network: it is important to protect your Wi-Fi network with a strong password and not to connect unknown devices to the network.
  • Control user access: it is important to limit user rights to what is necessary for their work.
  • Manage mobility: It is important to secure mobile devices, such as smartphones and tablets.
  • Keep your computer system up to date: It is important to regularly update your software and operating system, as updates often fix security vulnerabilities.
  • Take care of your digital identity: it is important to choose strong passwords and not reuse them across multiple services. It is also recommended to be vigilant about the websites and applications to which one gives access to one’s personal information.

What are the signs of a cyber attack ?

Be vigilant if you notice:

  • computer performance problems : slowdowns, crashes, breakdowns, etc.
  • unauthorized access to computer systems : remote connections, failed connection attempts, etc.
  • unauthorized modifications of data : file modifications, deletions or additions, etc.
  • suspicious emails or messages : emails containing attachments, malicious links, etc.
  • activities on social networks : publication of suspicious messages or content, etc.

You must act quickly by:

  • i ant the computer system to prevent the attacker from accessing other data or systems .
  • change passwords for all sensitive accounts .
  • Contact an IT security professional for assistance .

It is also important to report the attack to the appropriate authorities. This will help fight cybercrime and help other businesses protect themselves.

What tools to protect yourself?

Here are some examples of tools and resources that can be used to detect cyberattacks:

  • Computer security software , such as antivirus and firewalls, can detect and block malware and attacks.
  • Intrusion detection systems (IDS) can monitor network traffic for suspicious activity.
  • Security event management (SIEM) systems can collect and analyze security data from different sources to detect cyberattacks.
  • Cyber attack alert services can provide real-time notifications in the event of an attack.

Additionally, businesses can also put processes and procedures in place to detect cyberattacks. For example, they can train their employees to identify suspicious emails and links, and they can implement data backup and restoration policies.

And insurance to protect yourself?

Cyber insurance can also be a valuable tool for SMEs wishing to protect themselves against cyberattacks.

Indeed, cyber insurance can help SMEs cover the significant costs of a cyberattack and recover from the attack more quickly. It is a contract that allows a company to protect itself against the financial consequences of a cyberattack. Cyber insurance generally covers the following costs:

  • Costs to repair damage caused by the attack , such as restoring data, implementing additional security measures, or paying ransoms.
  • Communication and public relations costs related to a cyberattack.
  • Legal and judicial costs linked to a cyber attack.

Here are some tips if you want to take out cyber insurance:

  • Compare the different cyber insurance offers available on the market.
  • Make sure cyber insurance covers your business’s specific risks .
  • Read the terms of cyber insurance carefully before purchasing it .
