Cyberthreats are now too advanced for traditional security models that automatically grant users access once they’re inside a trusted network. In this environment, clicking on something as unassuming as a shopping link can lead to big problems, such as data breaches, ransomware attacks, and costly downtime. The zero trust security model is designed specifically to proactively address these kinds of issues.
What exactly is zero trust?
Zero trust is a cybersecurity framework that treats every user, device, and application attempting to access a file or system to be a potential threat. The framework enforces this by requesting an additional form of verification that requires active input from a trusted device or account before granting access. This double verification occurs at every stage of interaction.
Every access request is authenticated, authorized, and encrypted based on policies that consider factors such as user role, device health, location, and behavior.
Zero trust is built around the following core principles:
- Verify explicitly: Authenticate every attempt at access using multiple data points such as device integrity, geolocation, and user biometrics.
- Use least privilege access: Provide users with access rights strictly limited to what is essential for their assigned duties or specific functions.
- Assume breach: Operate under the assumption that your network has already been compromised by an attacker. Apply strict access controls to all movements, including files opened through links in accessible documents.
Why are more businesses adopting zero trust?
Zero trust is an essential tool because many businesses now operate with logistical flexibility that didn’t exist before 2020. Many business are facilitating work from home arrangements, satellite offices, and work from the field, thanks to deeper integration of cloud networks and mobile device security. This adaptability improves productivity and allows the business to take advantage of unique market opportunities, but creates more entry points for attackers.
Thankfully, zero trust is able to close these gaps, allowing businesses with any work setup to operate securely. Here are some reasons businesses are making the shift:
Better protection against internal and external threats
Insider misuse and stolen credentials are two leading causes of data breaches. Zero trust plays a key role in these situations because a zero trust system will still require an additional, irrefutable layer of authentication even if an attacker steals a legitimate user’s login credentials.
Improved visibility and control
Zero trust frameworks allow businesses to monitor who is accessing what, when, and from where. This provides a complete picture of network activity and helps identify unusual behavior, such as logins from a different country.
Compliance and data protection
Many regulations, such as HIPAA, GDPR, and SOC 2, require strict control over data access and security. Zero trust policies and security measures largely adhere to these regulations and best practices, significantly reducing compliance risk.
Stronger security for hybrid and cloud environments
As workloads move to the cloud, zero trust ensures that security policies extend beyond physical infrastructure and into multi-cloud or hybrid setups.
How zero trust works in practice
Zero trust frameworks require multiple technologies and processes working in sync. The most important components of zero trust include:
- Identity and access management (IAM): Centralized systems must verify users through multifactor authentication (MFA) and role-based permissions.
- Endpoint security: Every device trying to connect to the network must meet specific security standards before access is granted.
- Network segmentation: Dividing networks into smaller zones limits how far a potential attacker can move if a breach occurs.
- Continuous monitoring: Real-time monitoring of network activity and user behavior enables businesses to detect potential threats.
- Encryption and secure data handling: Data must be encrypted in storage and in transit to prevent misuse of or unauthorized access to sensitive information.
For many organizations, working with a managed IT services provider can simplify the adoption of zero trust. By leveraging external expertise and security tools, businesses can strengthen defenses while minimizing disruption to daily operations.
Zero trust is not a product, but an organizational mindset
A widespread myth about zero trust is the belief that it can be implemented with just one software tool. In reality, building a zero trust environment requires strategic planning, the right technology, and consistent policy enforcement. Once all of these are in place, businesses can create a safer, more resilient network where users can work confidently no matter where they are or what device they’re using.
