Zero Trust Security

What is SIEM software? How it works and how to choose the right tool

Evolving beyond its log-management roots, today's security information and event management (SIEM) software vendors are introducing machine learning, advanced statistical analysis and other analytic methods to their products.


This specific security model is designed to verify every person and device on a network. When any of them require access to the network, this solution verifies them without considering whether they are insider or outsider of the company. In this upgraded era of technology, threats can come from anywhere. So, it is not wise to trust the employees and all the machines within your network. This solution with its multi-layered dimension of security levels checks out the accessibility of the devices and persons.The castle-and-moat concept is an outdated traditional IT network security. It does not allow us to have access from outside the network easily. But the system remains vulnerable from the insiders’ threat. In this old-fashioned security, everyone inside the network is trusted by default. This blind trust can often result in serious damage to the company.

Case study

Today, companies do not keep their data in one place anymore. So, the appeal of castle-and-moat security systems is no longer valid. Many of them are using the cloud to store their data and it is difficult for single security to control the entire network alone. When anyone is not verified before having access to the network, hackers can have the chance to manipulate the network. They cause data breaches. According to the research by IBM states that a single data breach can cost over $3 million. If this is the average cost, then you can not say you are safe from the threats without using the zero-trust security.

Problem statement

You never can tell how trustworthy your employees are. Often they bring forth cyber attacks or threats to your network unknowingly. In the worst-case scenario, you might be the victim of intentional threats by your own employees. The automatic trust of the devices and the users are not safe anymore. The time-limit of any access can also have a negative effect on your network. Without this, anyone can stay a longer period in your network and try to cause harm. It is often evident that once an attacker gets access to the network, he can damage the entire network step by step. As the security perimeters are not segmented in several parts, one-time access is all the hacker needs to do the damage. Read more


At present, workloads are increasing frequently in companies. So, they need to store their data in public, private and sometimes hybrid clouds. This solution gives you deeper visibility into the activities of the users, devices, networks, applications, and data.
