The service of information security consulting allows a company to benefit from the expertise of a consultant, whether to fill a lack of expertise in one of the areas of security, to help in the realization of a project or to put in place processes that will enable it to better structure operational security. Through consultation, a company can save money and accelerate the security level of your organization to build a strong foundation in information security management. The company must keep in mind that security is played out on 3 levels: strategic, tactical and operational. If a company wants to become safer, it will have to ensure that it finds a balance between these 3 levels while taking into account its level of maturity. This is where the service of information security counsulting makes sense.
