Cybersecurity : best practices implemented by BeeBryte

CYBERSECURITY: Best Practices Implemented by BeeBryte.

In today’s increasingly technology-driven world, businesses are rapidly embracing digital transformation. However, this evolution raises many challenges, particularly in terms of cyber security, which can slow down their progress.

Lack of data protection, phishing, account hacking, and non-confidentiality represent a solid base from which many organisations can have their cybersecurity breached.

For a company like BeeBryte, where technology plays an important role in its business sector, it is essential to take proactive measures to ensure the smooth running of its offering and to guarantee good security for its stakeholders.

IT security can no longer be relegated to second place; it must be a major priority that is tempered because if we do not meet customer requirements, there will be a loss of trust. In this article, we’ll explore the various practices put in place by BeeBryte for good protection against cyber threats; to do this we’ll look at:

– Protecting our customers’ data

– The principle of least privilege

– Reducing the attack surface

– Security by design approach: security from the outset

– The shadow IT phenomenon: a risk to be avoided

– Raising staff awareness

– The pragmatic approach of ISO standards



– Protecting our customers’ data

BeeBryte takes IT security seriously, particularly as our solution interacts directly with systems that are essential to our customers, such as those that control heating, ventilation and other energy equipment.

Our main objective is to keep all information and data exchanged between on-site installations, our connection device (gateway/box) and our cloud platform totally isolated and safe from any unauthorised modifications.

Our team follows and monitors best practices and security alerts, in particular recommendations from recognised cybersecurity bodies such as ANSSI in France and the CSA in Singapore. These recommendations directly influence the security measures we apply.

To protect our customers’ data, we employ a comprehensive security strategy that includes:

  • Physical and digital access control: Only qualified BeeBryte personnel can access our gateway/box.
  • Data encryption and authentication: All communication between the gateway/box and our cloud platform is encrypted, and each connection must be authenticated to ensure that only authorised users or systems can access the data.
  • Secure remote updates and maintenance: We can remotely update our gateway’s operating system and applications to correct any potential security problems. The aim is to comply with a patch management policy for all our equipment.
  • Regular back-ups: We back-up and archive data so that it can be restored quickly in the event of an incident.

Various data can be retrieved from the customer’s equipment. These include supply, return, defrost and outdoor temperatures, as well as temperature, pressure and defrost setpoints. It also includes the status of equipment such as valves, defrosts, fans, compressors and alarms.


– The principle of least privilege

Within the BeeBryte organisation, we ensure that employees or systems only have access to the information they need within the internal IT system. To achieve this, each user or system is assigned a role in the various departments, with permissions corresponding to what is necessary for them to carry out their tasks. We regularly check compliance with this principle by reviewing access to verify the consistency of information and detect any unauthorised accounts.

For example, certain data may be released unexpectedly, either by an employee (acting in good faith) or by following the compromise of a human or technical account. This can lead to risks by leaking sensitive information.

Another aim of this approach is to reduce the cross-functional impact between the customers that BeeBryte manages.

Finally, we apply the principles of defence in depth to strengthen our systems against threats, putting in place a few security measures to defend our systems more effectively.


– Reducing the attack surface

Today, there are many online scanners competent in identifying all the elements exposed on the internet linked to a given target. Everything we expose on the internet is potentially accessible to anyone, from anywhere. Our approach is to limit as far as possible what is available directly on the internet.

Although our BeeBryte site is designed to be accessible on the internet, any tool intended for internal use only will not be exposed on the web, only on our internal network.


– Security by design approach: safety from the outset

The “security by design” approach represents an evolution in the way we approach the security of IT projects. Rather than leaving security as an afterthought, this approach seeks to integrate security requirements from the earliest design phases of a project.

Historically, security was often seen as a final step, resulting in higher costs to correct deficiencies detected late on. By investing in safety upstream, we make it easier to modify safety aspects that may not be properly implemented or considered at the outset of the project.

By adopting this method, we guarantee cost optimisation while ensuring that every element of the design complies with the required safety standards.


– The “Shadow IT” phenomenon: a risk to be avoided

Shadow IT occurs when departments or employees use company software or tools without the knowledge or direct agreement of the IT department. This exposes the organisation to security and compliance risks, as these elements are not considered in the company’s IT or cyber strategy.

This phenomenon has recently increased with the advent of teleworking, giving employees access to unsecured applications from home.

Another component of this phenomenon is everything that automation engineers, maintainers and technicians install on customer networks without the knowledge of their respective IT departments. To remedy this situation, it is imperative to train staff and raise their awareness of security, and to promote a culture of transparency in which all employees are encouraged to report their technology needs.


– Raising staff awareness

We regularly organise security awareness sessions for newcomers and existing staff to share good day-to-day practices. These sessions cover topics such as protection against phishing, which is a form of attack in which fraudsters try to obtain confidential information by posing as legitimate entities, through fraudulent emails or websites.

One example of phishing is when you receive an e-mail asking for your bank details and your ID because you have won X euros. This is a risk that should be totally avoided and reported.

During security awareness sessions, we cover practical advice on how to identify and respond to phishing attempts, as well as how to keep accounts and passwords secure. In addition, we raise awareness of the precautions to be taken when surfing the internet, and also in the use of USB devices, to minimise security risks.

– The pragmatic approach of ISO standards

There are more than 23,000 ISO (International Organisation for Standardisation) standards covering fields such as management, technology and the production process. They have been developed to help (mainly large) companies manage and develop their offering.

When it comes to safety, rather than complying with these standards, which can be costly, we are adopting a pragmatic approach, drawing on available national resources to establish a minimum safety base.

We follow the ANSSI recommendations for VSEs/SMEs, as well as the IT hygiene guide. This approach enables us to reach an initial level of maturity in terms of security and to comply with national requirements, while gradually committing ourselves to higher security objectives.

We favour a proactive, voluntary approach rather than waiting for compliance to become a legal or contractual obligation.



It is essential to remember that cybersecurity is not just a series of technical measures; it represents an ongoing commitment on the part of any organisation, which must constantly adapt and strengthen its security practices to deal with evolving threats.

At BeeBryte, we take this challenge very seriously, integrating security into every stage of our operations and instilling a culture of cybersecurity that involves every member of our team.

By following robust principles such as security by design, least privilege and keeping abreast of international best practice and standards, we not only ensure that our customers’ critical data and energy devices are protected, but also contribute to a safer digital environment for all.

All of these good practices form the basis on which we can move forward with complete peace of mind. Once all these practices have been put in place and integrated into the way the company operates, we can move on to much more important and structural projects (ISO 27001, etc.).
