Over the last few years, the way we work has changed significantly (especially post-Covid). Employees are now working more flexibly for a better work-life balance but understandably, many businesses have struggled to keep their security policies up to date in line with the rapid pace of change. With the rise in people now working remotely, data being stored and accessed in the cloud, and cyber threats being more sophisticated, relying on the old models that assume everything “inside the company” is safe, simply don’t work with how you work anymore.
That’s where Zero Trust comes in. A modern approach to security designed for how businesses actually operate today. So, let’s break it down.
Why Traditional Security Models No Longer Work
Traditional IT security models were built around a perimeter. If you were inside the company network (in the office, on a managed device), you were considered “safe.” That made sense when everything lived in one place, but today many businesses promote more freedom for their employees giving them the option to work from home (or anywhere else) and use their own devices. Additionally, most applications are now more commonly hosted in the cloud and data tends to be shared over cloud platforms for teams to collaborate effectively. This means that effectively, the network perimeter has disappeared so we need to adapt how we protect our systems from cyber threats.
What Is Zero Trust?
Zero Trust is a security concept based on a simple, but effective, principle: “never trust, always verify”. Instead of assuming that everything inside your network is safe, Zero Trust assumes the opposite; that no user, device, or app should be trusted by default, no matter where it’s located.
Every access request must be:
- Verified: is this user who they say they are?
- Authorised: do they have permission to access this resource?
- Contextually Validated: are they accessing from a secure device, in an expected location, at an expected time?
Only after passing these checks is access granted. If anything changes, such as logging in from a new location or on an untrusted device, access can be re-evaluated.
How Zero Trust Works in Practice
Zero Trust isn’t a single product; it’s a mindset and a collection of technologies working together.
Here’s what that typically includes:
Strong Identity Verification
Use Multi-Factor Authentication (MFA) and Single Sign-On (SSO) to make sure users are who they say they are and that they’re using secure, approved credentials.
Least Privilege Access
Users should only have access to the data and systems they need, nothing more. Think of it like having keys to only the rooms in the building you work in, not the whole office.
Device Trust
Verify that the device trying to connect is healthy and compliant. This can include up-to-date antivirus, disk encryption, and being enrolled in Mobile Device Management (MDM) like Apple Business Manager or Microsoft Intune.
Continuous Monitoring
Just because a user was verified once doesn’t mean they should stay trusted forever. With Zero Trust, behaviour is continually monitored, and access can be revoked if anything suspicious is detected.
Micro-Segmentation
Rather than one big network, divide systems into smaller zones. If a threat enters one area, it can’t spread laterally to everything else.
Why Zero Trust Matters More Than Ever
In 2025, the stakes for business cybersecurity have never been higher. Ransomware attacks continue to rise and phishing is more sophisticated. Insider threats (both accidental and malicious) are a growing concern. Even large businesses are seeing costly breaches which can be devastating and cause trading to come to a halt.
Regulatory pressure (e.g. GDPR, ISO 27001) is also increasing and people are more concerned about the security of their data (as they should be).
Zero Trust helps you stay ahead by focusing on minimising risk, limiting exposure, and responding faster. It’s not just about security, it’s about business continuity, customer trust, and reputation.
Zero Trust on Apple Devices + Microsoft 365
For Apple-based businesses, Zero Trust is more achievable than ever:
- Use Apple Business Manager and MDM to enforce device compliance and actively monitor the security of your endpoints.
- Leverage Microsoft 365 Conditional Access to control access based on risk levels. Lock your systems down as much or as little as you need to.
- Apply Azure AD Identity Protection and Intune to manage identities and devices together.
Getting Started
Implementing Zero Trust doesn’t mean overhauling everything overnight. You can start small:
- Roll out MFA for all accounts and ensure your team are using secure passwords. Password managers such as Keeper can be effective for this.
- Review user permissions (especially for cloud platforms). Inception Support can provide a full IT review with our consultancy service, to give you full visibility. Find out more here.
- Monitor device health and bring your endpoints under management. Enrolling your devices into ABM and Addigy (MDM) means that you can have an overview of all of your Apple devices, and Inception Support can look after things in the background so you don’t even need to think about it.
- Educate your team on phishing, social engineering, and security hygiene. Speak to Inception Support if you would like cybersecurity training for your users
The goal is progress, not perfection!
The Take-Away
Zero Trust isn’t just another cybersecurity buzzword. It’s a practical, necessary shift in how we think about business security in an increasingly remote, cloud-first world. It might sound a bit intense, but done right, it’s one of the best things you can do to future-proof your organisation.
