The prevention protocol is usually bundled with software, hardware, and policies. The prevention measures cover encryption programs, application firewalls, patch management, and biometric authentication systems.

Cloud Security

Cloud Security refers to the particular set of policies and technologies that preserve data and infrastructure involved in a cloud computing environment.

Endpoint Security

Endpoint Security is a methodology for the safeguarding of corporate networks that are remotely connected to client devices. The connection of Laptops, Tablets, Mobile phones and other wireless devices to corporate networks creates an entry point for security threats. So, Endpoint Security is devised to make sure that all devices connecting to a network follow the defined level of compliance standards.

Internet Security

Internet security refers to various security measures exercised for ensuring the security of transactions done online. In the process, the internet security prevents attacks targeted at browsers, network, operating systems, and other applications. The main aim of Internet security is to set up precise rules and regulations that can deflect attacks that arise from the Internet such as the DDoS attacks.

Mobile Security

Mobile device security is the protection of sensitive data stored on and transmitted by smartphones, tablets, laptops and other portable computing devices. It is also known as the wireless security.

Network Security

Network Security is the protection of a network infrastructure and the devices connected to it. The protection process covers technologies, policies, and practices. It is aimed at safeguarding threats such as unauthorized access, and malicious use and modifications.
