TL;DR: Zero-trust involves believing that no user or application should be granted automatic trust. It encourages organizations to verify every access while treating every user or application as a potential threat. Zero-trust is a great starting point for businesses that want to build formidable cybersecurity. It can adapt to the complexity of the modern work environment. This includes a hybrid workplace and protects people, devices, applications, and data.
Zero-trust should not be mistaken for a solution or a platform, regardless of how security vendors market it to you. You can’t just buy it from a security vendor and implement it with the click of a button. Remember these three principles when implementing zero trust:
1. Never trust, always verify
Adopt a “never trust, always verify“ approach to security. Instead of assuming that a user, device, or application is trustworthy because it has connected before, verify every request for access. Confirm identities, check permissions, and make sure users can access only the systems and information they need to do their jobs.
Support this approach with strong identity and access management (IAM) controls.
- Define clear roles, assign permissions based on job responsibilities, and review user accounts regularly to ensure access remains appropriate.
- Remove or update permissions as employees change roles or leave the organization, and require multi-factor authentication (MFA) whenever possible to provide an additional layer of protection.
- Finally, monitor login activity for unusual behaviour, such as sign-ins from unfamiliar devices or locations. By continually verifying users and their access rights, you can reduce the risk of unauthorized access and limit the impact of a compromised account.
2. Zero-trust: Limit access
Misuse of privileged access is one of the most common reasons for cyberattacks. Limiting access ensures that users are granted minimal access without affecting their day-to-day activities. Here are some standard security practices that organizations have adopted to restrict access:
- Just-in-time access (JIT) – Users, devices or applications are granted access only for a predetermined period. This helps determine the time one has access to critical systems.
- Principle of least privilege (PoLP) – Users, devices or applications are granted the least access or permissions needed to perform their job roles.
- Segmented application access (SAA) allows users to access only permitted applications, preventing malicious users from gaining access to the network.
3. Assume a breach and maximize cybersecurity
Don’t wait for a cyberattack to reveal weaknesses in your defences. Instead, assume that a breach has already occurred and build your security strategy accordingly. This mindset encourages you to verify every connection, monitor for suspicious activity, and respond quickly when something doesn’t look right.
Treat every application, service, identity, and network—whether inside or outside your organization—as potentially compromised. By limiting access, segmenting your network, and continuously monitoring your environment, you can detect threats sooner and contain them before they spread. Assuming a breach also helps you improve incident response, reduce the impact of an attack, and strengthen your overall security posture. Most importantly, it helps protect your data, your employees, and your business.
