In today's interconnected world, cyber attacks have far-reaching consequences, ranging from identity theft to the loss of critical data. The security of critical infrastructures such as hospitals or financial services is imperative for the smooth running of society. Cyber-threat researchers, such as Cyllene's team of specialists, play a key role in identifying new threats, raising public awareness and strengthening the tools available to guarantee security on the Internet, thus ensuring a safer environment for all.

What is Cyber Security?

Cybersecurity, or information systems security, aims to protect a wide range of devices, networks and data from malicious attacks, whether in the context of corporate computing or on mobile terminals. It falls into a number of specialized categories.

• Network security aims to counter intrusions and malware, securing the computer network.


• Application security comes into play right from the design phase, to prevent threats that could compromise data. Guaranteeing data integrity and confidentiality, information security applies equally to data storage and transmission.


• Operational security manages data protection processes, including user authorizations and storage policies.


• Disaster recovery and business continuity strategies determine a company's response in the event of a major incident, and its procedures for getting back to business as usual.


• Finally, end-user training underlines the importance of making individuals aware of good practices to reduce risks, such as avoiding suspicious attachments or not connecting unidentified devices, thus reinforcing corporate security.

Our cybersecurity experts will guide you through all these stages, to provide you with the offer best suited to your needs.

Cyber threats

Cyber threats encompass a range of digital dangers, including attacks such as phishing, ransomware, malware and other malicious tactics aimed at compromising the security of data and IT systems.

• Phishing, a common cyber-attack technique, involves sending fraudulent e-mails masquerading as legitimate communications, with the aim of stealing confidential information, such as login data or credit card details. Education on security practices and the use of technological solutions for filtering malicious e-mails are effective ways of guarding against this threat.


• Ransomware, a form of malicious software, aims to block access to computer files or systems in exchange for a ransom. However, payment of the ransom does not guarantee data recovery or system restoration. Ransomware defense solutions and informative guides can be valuable resources in countering this attack.


• Malware, another type of malicious software, aims to gain illegal access to a system or cause damage. Specific protection solutions, such as Cisco Secure Endpoint, offer effective means of countering these threats. Social engineering, a tactic in which hackers entice people to divulge sensitive information, can be combined with other threats to increase the chances of clicking on malicious links or downloading harmful software. Knowledge of social engineering techniques can reinforce vigilance and protection against these attacks.

From user training to firewalls, Cyllene can help you implement your cyber security strategy.
