Why Zero Trust Is The Future Of Cyber Security

Zero Trust

With the rise in cyber-attacks and successful data breaches, it is clear we need a new approach to how we protect our IT environments from hackers. Zero Trust is commonly spoken about as the new evolution in cyber security. In this blog post, we explain what Zero Trust is, the benefits and challenges, and how to implement a Zero Trust model for your organisation.

What is Zero Trust?

In cyber security, the concept of zero trust refers to the idea that organizations should not automatically trust anything inside or outside their network boundaries, and instead should verify anything and everything trying to access their systems before granting access. This approach is based on the assumption that it is difficult, if not impossible, to determine with complete certainty whether a user, device, or network is completely secure, so it is better to be cautious and verify all access attempts.

Organisations that adopt a Zero Trust security model are able to better defend against cyberattacks and improve their overall security posture. By verifying the identity of users and devices, Zero Trust can help prevent malicious actors from gaining access to sensitive data. Additionally, by forcing users to authenticate before accessing data or resources, Zero Trust can help ensure that only authorized users are able to access sensitive information.

Overall, Zero Trust is a more effective security model than traditional perimeter-based security because it helps organisations better defend against sophisticated attacks. Additionally, Zero Trust can improve an organisation’s overall security posture by verifying the identities of users and devices, and by forcing authentication before allowing access to data or resources.

The Benefits of Zero Trust

In a world where data breaches are becoming increasingly common, organisations are looking for ways to better protect their information. One approach that is gaining popularity is known as “zero trust.”

Zero trust is a security model that does not rely on predefined trust levels. Instead, all users and devices are treated as potential threats. This means that every user must be authenticated and authorized before they can access any resources.

There are several benefits of using a zero-trust security model:

  1. Enhanced Security: By treating all users and devices as potential threats, organisations can better protect their data from attacks.
  2. Improved Productivity: Zero trust can help organisations improve their productivity by reducing the need for manual processes and approvals.
  3. Cost Savings: Zero trust can also help organisations save money by eliminating the need for costly hardware and software solutions.
  4. Increased Flexibility: A zero-trust security model provides organisations with increased flexibility when it comes to managing their networks and applications.
  5. Improved User Experience: Finally, zero trust can also improve the user experience by providing them with more control over their data and privacy settings.

How to Implement Zero Trust?

There is no one-size-fits-all answer to the question of how to implement Zero Trust, as the approach will need to be tailored to the specific needs of each organisation. However, there are some general principles that can be followed in order to create a successful Zero Trust environment:

  1. Establish strong identity and access management (IAM) controls. This includes ensuring that all users have unique and strong passwords and that these passwords are changed on a regular basis. Furthermore, it is important to have implemented two-factor authentication (2FA) for all sensitive systems and data.
  2. Implement least privilege principles. Users should only be given access to the systems and data that they absolutely need in order to do their jobs. This minimizes the potential damage that can be caused by malicious insiders or external attackers who gain unauthorized access.
  3. Use micro-segmentation to segment your network into smaller, more manageable chunks. This makes it easier to control and monitor traffic flows, as well as isolate any compromised systems from the rest of the network.
  4. Continuously monitor activity on your network using both automated tools and manual reviews. This helps to identify any suspicious behaviour so that you can take appropriate action to mitigate any risks.
  5. Educate employees about cyber security best practices and make sure they understand their role in protecting the organisation from attacks. By raising awareness of potential threats, you can help employees become your first line of defence

What are the Challenges with Zero Trust?

The challenges with Zero Trust are largely due to the fact that it is a relatively new concept, and as such, there is not a great deal of real-world experience with implementing it. Additionally, because Zero Trust requires a complete rethinking of how organisations approach cyber security, it can be difficult to get buy-in from all stakeholders. Finally, because Zero Trust necessitates tight controls on access to data and systems, it can require significant investment in terms of time and money.


Overall, the goal of a zero-trust approach is to prevent unauthorized access to an organization’s systems and data and to limit the damage that can be done if a security breach does occur. By constantly verifying access attempts and limiting access to only those that are absolutely necessary, organizations can better protect themselves from cyber threats and improve their overall security posture.
