Security as a Service (SecaaS): A Comprehensive Guide

In today’s digital landscape, where cyber threats are constantly evolving, businesses need a robust and comprehensive approach to security. Security as a Service (SecaaS) has emerged as a powerful solution, offering a wide range of security services delivered on a subscription basis. This comprehensive guide will delve into the intricacies of SecaaS, exploring its benefits, types, deployment models, considerations, and future outlook.

What is Security as a Service (SecaaS)?

SecaaS, as the name suggests, is a cloud-based security model that provides various security services to businesses through a subscription or pay-as-you-go model.
