Network Security Services
Our network security services include managed security services and global security consulting services for enterprises.
Managed Security Services (MSS). Our MSS services enable enterprises to effectively monitor and manage their network security infrastructure on a 24x7 basis while reducing the associated time, expense, and personnel commitments by relying on VeriSigns security platform and experienced security staff. Our MSS services include:
Global Security Consulting Services. Our Global Security Consulting Services help enterprises assess, design, and deploy cost-effective and scalable network security solutions. Our consulting services are also available to help enterprises integrate our PKI services with existing applications and databases and advise on policies and procedures related to the management and deployment of digital certificates.
Authentication Services. Our Authentication Services include our Managed PKI Services, Managed PKI Fast Track Services and Unified Authentication that can be tailored to meet the specific needs of enterprises that wish to issue digital certificates to employees, customers or trading partners.
VeriSign Affiliates typically enter into a multi-year technology licensing agreement with us whereby we receive up-front licensing fees for the Service Center or Processing Center technology, as well as ongoing royalties from each digital certificate or the Managed PKI Service sold by the VeriSign Affiliate.
