The biggest potential drawback of ZTNA is having weak user administration. ZTNA requires good identity management and clear access policies. Not having those foundations in place can mean ZTNA takes longer to implement.
Our working lives are faster, more complex, and more demanding than ever before.
People are constantly switching between apps, devices, and decisions. They often do so under pressure and without clear signs of what’s safe. In that kind of environment, mistakes are bound to happen - bad actors are counting on it. That’s why human error still sits at the centre of most security incidents.
Work has changed, but it’s making secure behaviour harder than it should be.
And according to a recent McKinsey report, the rise of generative AI has only made things more complex. Phishing campaigns have grown by 1,200 per cent since 2022 - meaning a single wrong click can now open the door to an entire environment.
So, what does all this mean? As cyber threats change, so too must our defences. In a perfect world, the aim is still to keep attackers out. But security teams know that prevention alone is not enough. You also need to limit the damage if someone gets through, which is where older remote access models are no longer enough.
In this blog, we’ll explore how zero trust network access can ensure you’re ready for future threats.
What are ZTNA solutions?
Zero Trust Network Access (ZTNA) is built on one simple idea: that trust should never be assumed. When using ZTNA solutions, every user, every device, every request must earn its access rights on every visit.
This means that, instead of opening up an entire network for everyone, ZTNA connects users only to the applications they are approved to use. Its access decisions are based on things like the user’s:
Identity
Device information
Location
Behaviour
These checks continue throughout the session, rather than stopping once a login is complete. And instead of showing everyone everything, users are limited only to what they need to do their job. They can’t just browse your network or move between systems unless explicitly allowed. This massively reduces your attack surface and limits the impact, should a cyber incident happen.
How does ZTNA handle remote access?
ZTNA is a particularly appropriate way to handle modern work environments. After all, the idea of a defined network boundary just doesn’t exist anymore. Your applications might be in the cloud or on-premises, with data moving between platforms and users connecting from home, customer sites, shared workspaces, or anywhere else in the world.
When connections can come from anywhere, it makes no sense to give out trusted access easily. Instead, ZTNA handles remote access by removing the idea of a single network. Users don’t connect to your entire network, but to specific applications through a secure broker. This checks who they are and whether they have the right to be there.
For your business, this approach reduces risk in a few crucial ways:
Users can’t see systems they are not authorised to access
Attackers can’t move around the entirety of your environment unchallenged
Access can be blocked instantly if a user raises suspicions
Another bonus? ZTNA actually simplifies your security stack. Rather than having a mishmash of multiple tools to manage remote access, ZTNA brings access control into a single, policy-driven layer.
Zero Trust Network Access (ZTNA) is an application-focused security architecture where access to applications is granted based on verified identity, device posture, and contextual policy evaluation rather than network location. Users and devices authenticate via an identity provider (e.g. SSO using SAML) and connect to a ZTNA gateway or access proxy that checks user identity, device health, location, time, and risk level before enforcing relevant access policies. If approved, the gateway creates a proxied, encrypted session directly from the end user’s device to the specific application, not the broader network.
All traffic passes through the gateway for ongoing inspection, and access can be revoked if needed. This replaces traditional VPNs, reduces perimeter controls, and merges authentication, segmentation, and inspection, which simplifies infrastructure and improves security.
Why ZTNA benefits remote teams
But what about your users? You might not believe us if we tell you that your end users often feel the pain of outdated security first. But it’s true. Slow VPN connections, dropped sessions, repeated logins, and unclear access rules can all make their day-to-day work a chore. That’s without mentioning your IT team trying to keep up with their tickets.
ZTNA helps both sides. For IT teams, it makes things like onboarding, applying policies, and spotting issues much simpler. And for users, access is usually automated and faster now that they’re no longer relying on traditional VPN connections.

There’s usually no major overhaul required, either. ZTNA doesn’t replace everything you already use; it integrates with your existing tools like identity platforms, endpoint security, and monitoring. It’s a much more practical way to roll out modern cyber security.
What are the different types of ZTNA for remote teams?
As you might expect, cloud-delivered ZTNA services are popular for distributed teams. They scale easily and reduce reliance on old VPNs and on-prem infrastructure. Hybrid approaches can also support you if your business still relies on data centres or more specialised systems.
But what matters most is integration. Effective ZTNA works alongside existing identity, monitoring, and endpoint tools so you can move toward a full zero trust model without rebuilding your environment from scratch.
Remote teams ZTNA best practices in 2026
For remote organisations implementing ZTNA in 2026, here are some best practices.
1. Start with a thorough overview of your environment
Before changing access models, you need to understand what you have. That includes users, devices, applications, data flows – anything that goes into making your business tick. Gaps in visibility often become obvious at this stage, which is a useful outcome in itself.
2. Implement strong identity & access (IAM)
Strong identity management is absolutely fundamental for ZTNA. You’ll need centralised identity platforms combined with multi-factor authentication to provide the foundation for your reliable access decisions.
3. Segment and protect data
Modern security should assume that risks already lie inside your network. Planning for the worst in this way limits the damage, should something happen.
Take a look at your system. You’ll notice that tools and data don’t all carry the same level of breach risk. Grouping applications by sensitivity helps focus controls where they matter most. Then, ZTNA enforces these boundaries without relying on complex, unmanageable network rules.
4. Apply least privilege everywhere
Next, give people access to what they need to do their jobs. No more. Access should be granted for a reason and reviewed regularly using a least privilege approach. This again reduces the impact of compromised accounts and limits accidental misuse.
5. Verify users and devices everywhere
Unlike older security models, ZTNA checks don’t stop after the first login. Device health and user behaviour are a part of the decision process throughout each session, letting security adapt to any changes.
6. Use the right systems
Attackers are using the latest tools and tech. And so should you. Things like security dashboards, alerts, automated policy enforcement, and network monitoring all help your team manage ZTNA without adding workload.
7. Monitor and keep improving
Much like other areas of IT, ZTNA is not a one-off project. Holding regular reviews and audits will help you maintain policies that still reflect how your staff can work securely, even as threats change.
What is the future of ZTNA?
ZTNA solutions for remote teams in 2026 are all about earning access. And in the future, ZTNA will become even more important for the most secure networks. Instead of bolting on more software and tools, organisations are starting to look for simpler, centrally managed solutions that actually support their remote work instead of making it harder.
We’ll also see AI-driven threat detection and automation playing a bigger role each year, helping teams detect unusual behaviour earlier and respond faster. The long and short of it is that organisations want stronger security without increasing workloads. ZTNA fits naturally into that.
ZTNA keeps your data safer by making sure only the right people on trusted devices can access it. Even if something goes wrong, it limits the damage by containing the threat. Right now, IT teams are under pressure. ZTNA helps by cutting down complexity, easing compliance, and keeping things secure, without getting in anyone’s way.
