Your network? Far more than a fortified castle!

Let's take a small step back in time... In the Middle Ages, castles were equipped with walls, arrow slits and moats. The guards also ensured the protection of each inhabitant by scanning the horizon. These methods proved to be effective against enemy invasions! As long as the attack was carried out from the outside...

But what about the people inside the fortress? Can we trust them blindly? Is there not a risk of betrayal or uprising? What about temporary passers-by? And potential spies?

The "zero trust" principle applies: just because people have entered the castle with permission does not mean that we should not continue to keep an eye on their movements and adapt accordingly to ensure that no "strange" activity takes place.

QUANT adopts the same philosophy for your network! All devices and users are untrustworthy until proven otherwise. This vision casts a fresh glance at traditional solutions: it protects a local network, a Cloud or a hybrid infrastructure, in which resources and employees are spread over several locations. 

 

The security for your local, hybrid or Cloud network in 4 steps:

  • Visualisation and authentication
    We take the time needed to understand your technology environment and the data that flow in your architecture. Each (internal or external) user and device (IoT) is identified through an authentication process before access is granted to the various resources and applications. This can be done using the 802.1X protocol or by relying on other techniques such as MPSK, Captive Portal, ...

  • Assigning a role
    First step done! You can now assign a specific login role to each individual or device. This is based on a logical grouping of granted rights (access or no access to certain applications, to communication with other devices, to Facebook or YouTube during breaks...). These are variable and independent of the place where the identity is located. Does one of your employees work from home or in a nearby café? The level of protection of your system will remain the same.
    You can monitor traffic and segment your network dynamically according to assigned roles. Depending on their activities, users will be able to gain or retain access to various applications and data. The icing on the cake is that this control is fully automated!

  • Limitation
    Any anomaly is quickly detected thanks to continuous, careful monitoring and analysis of traffic. In case of breaches, threats are immediately quarantined or disabled. Micro-segmentation effectively prevents propagation

  • Optimisation
    QUANT’s goal? To maintain control and extend security throughout the network, while optimising the end-user experience and internal IT organisation. We ensure that your business remains operational, even in the face of cyberattacks.

frequently asked questions

 

Why should you secure your computer network?

Data theft, identity theft, denial of service, blackmail via ransomware... The consequences of an unsecured system can be disastrous. That can have a negative impact on the company's reputation and break the trust between employees and shareholders, not to mention the loss of competitive advantages. The worst-case scenarios could be legal action and company bankruptcy.  

 

What are the most common cyberattacks on businesses?

  • Phishing: this technique consists of tricking users by sending them a fraudulent e-mail in order to get their personal data.  
  • Exploitation of a software flaw
  • The president scam: although the name of this threat may make you smile, the process is anything but positive! The fraudster contacts a target company by phone or e-mail, pretending to be the president of the parent company or group. After establishing a climate of trust, the malicious person asks for an unscheduled, urgent and confidential international transfer.
  • Brute force login attempts
  • Acquisition of illegitimate names and domains
  • Denial of service attack: this aims to make a server inaccessible in order to cause a breakdown or malfunction of the service.
