Compare the SD-WAN Market

Security has become one of the core requirements of any technological solution as the ever evolving threat landscape has further exemplified the need for strict security requirements. This increasingly complex nature of security and the ever more global workforce has stretched most IT departments to their limits, which negatively impacts the overall security posture of organizations.

What is a Managed Security Service Provider (MSSP)?

As the name implies, these are service providers who offer managed security services at scale which reduces the management burdens of in-house IT departments. MSSP or Managed Security Service Providers specialise in providing security services across the board for your business. They achieve business outcomes by providing services such as Managed Detection and Response (MDR), Cloud Access Security Broker (CASB), NextGen Firewall as a service (NextGen FWaaS), Security Event Monitoring and Event Management (SIEM). These services cover all security aspects of an organisation, from single-user devices to SD-WAN, Edge Computing, and even Cloud Security.
