NS One is a French publisher and vendor of application security solutions, with particularly well-developed expertise in the design of solutions for application security, analysis, monitoring and correlation of security, network and server logs (Security Information & Event Management).
Experience with security problems, acquired through major account work over many years, shows that an approach consisting of piling up security bricks to protect the enterprise Information System has reached its limits. In fact, networks are opening up more and more to facilitate and accelerate company business processes, and this has resulted in an explosion in the number of security breaches and a realization that the massive investments made in security equipment have been ineffective.

Furthermore, offerings that allow supervision and monitoring of infrastructure elements (Security Information & Event Management) are also showing their limits, since, in order to be relevant, the information transferred by these systems must take into account the context in which they were collected, in other words the type of application, the risk level and, more generally, the company’s objectives in the area of security (risk management). It is therefore clear that analysis of security events can only be relevant if it is strongly coupled to the security perimeter and equipment defined by these events.

Companies today are no longer looking for security technologies; they are looking for solutions to manage security in a given application context. In other words, they start with a project linked to their business, such as, for example, the setting up of roaming access, and integrate into their project a solution that will allow implementation of adequate security and monitoring of this security in function of the project context and associated risks. Consequently, roaming access security can not be treated in the same way as the security of a web or e-mail server.

NS One is an ideal provider of solutions for secured access to enterprise applications.

Relying on its know-how and the technologies it has developed, NS One guarantees its customers a high level of security that perfectly matches the incurred risks.

Thanks to a very modular technology, NS One builds solutions that are suited to its customers’ environment and needs. These solutions make it possible to administer and monitor application security in a relevant manner, by associating security technologies (IPS, authentication, etc.) on a common platform and by integrating a new approach in the area of security event correlation.

NS One offers an approach to IT application security that is resolutely efficient and unique in meeting the needs expressed by customers
