DOMAIN NAME

Managing and securing a portfolio of domain names – Key Accounts

A portfolio of domain names is an invaluable asset for an organisation. And yet in many cases it is the result of several decades of acquisitions carried out haphazardly, with no unified standards and with no one in charge. The risks entailed by this scattered approach are numerous: uncontrolled costs, poor online brand protection, endangering the information system, damage to the brand image, etc. It is nowadays essential to put in place a pertinent and effective domain names policy in order to protect your digital territory and your brand in the broader sense.

CYBERSECURITY
DOMAIN NAME
ONLINE ABUSE

Domain names and online abuse

Domain names constitute sources but also targets of malicious practices on the Internet, including cybersquatting, typosquatting and phishing. Yet specialists are still struggling to classify the numerous types of abuse to which they are subject and to act with the appropriate legal tools. For domain name professionals it is imperative to master the legal context and the most appropriate solutions for identifying, preventing and putting a stop to these various kinds of abuse and thus support their clients in protecting and defending their rights (domain names, brands and trademarks, signs and logos, corporate names, etc.).

DNS Administrator

For some years now, both public and private actors have been seeing certain Internet services become inaccessible on account of problems linked to their DNS hosting. These breakdowns have considerable consequences: clients unable to access their bank accounts, online stores inaccessible, public services closed, etc. The robustness of DNS services generally suggests that Internet services are functioning normally; so, without a suitable DNS administration, an organisation can become extremely vulnerable. It is essential for any organisation to have skilled administration that allows it to maintain a comprehensive, high-quality DNS service, whether it is hosted in-house or entrusted to a hosting service provider.
