Three Best Practices to Ensure Cybersecurity for Your SME

Many SMEs underestimate the threat of cybercrime, investing less in this area, convinced that they are not prime targets. However, statistics demonstrate that this perception is incorrect: 40% of cyberattacks target SMEs. Indeed, their often weaker security levels make them ideal targets, providing cybercriminals with easier opportunities to bypass their defense systems.

The consequences (data losses combined with business disruption) can, in some cases, be dramatic and lead to bankruptcy.

However, means to protect your IT installations, data, and thus your business, exist.


Identify Risks

First of all, as James R. Clapper, former Director of National Intelligence for the United States said, “you cannot protect what you do not know.” This also applies to your infrastructure (hardware, software, data center, etc.). Therefore, a regular audit is important, as it allows you to take stock of the situation and identify vulnerabilities to address them immediately.


Train Employees

Knowing it can happen is not enough; several preventive tools must be implemented. Antispam and antivirus systems are essential. But to be fully effective, they must be regularly updated, properly configured and comply with current standards.

Fundamentally, and regardless of the tool, every employee must be aware of risks and know what actions to take in the event of a suspicious email. Sometimes, implementing a simple policy for incoming emails and/or consulting an IT expert can be enough to prevent disaster. It is also recommended to conduct fake phishing campaigns within your company to train employees to recognize risks, as security is everyone’s responsibility.


Implement Strong Passwords

It’s often said but too little done : passwords are an important lock. Therefore, implementing an internal policy for strong passwords, combined with a multi-factor authentication (MFA) approach using mobile phones, is an excellent practice.


Regularly Test Backups

If your data is encrypted by a cyberattack and you don’t have a backup, that data is simply lost and unrecoverable. That’s why a reliable backup system is so important. But having a backup is not enough; it also needs to be tested regularly to ensure that the data is fully recoverable and error-free in the event of a crisis.

Backups are often installed on-site, but it is safest to have both on-site and decentralized backups. If you prefer to use an application, make sure it is disconnected from the servers to prevent the backup data from also being encrypted in the event of an attack.

How do you know which solution is suitable for your SME, for your situation? An audit can answer this question and present the best alternative.


In short: nowadays, the question is no longer WHETHER your SME will fall victim to a cyber attack, but WHEN.
