Quick Summary
In 2025, the global average cost of a data breach is on the rise, exceeding $4.8 million.268 and identity-based attacks make up 79% of breaches, according to IBM's latest X-Force Threat Intelligence Index.
With remote work options, the widespread adoption of multi-cloud and hybrid environments, and perimeter-based defence, are proving to be inadequate. Through this lens, we can clearly see why zero-trust architecture provides an essential approach to cybersecurity.
By implementing zero trust, no device, user, or system is automatically trusted, leaving nothing and no one to chance. Zero trust has transitioned from concept to boardroom concern as enterprises, particularly in a post-cloud revolution world, ramp up their efforts to secure the premises.
In this blog, we will outline how zero trust works, why it matters, and what businesses need to do to keep pace.
What is zero trust architecture in cybersecurity?
Zero trust architecture is a contemporary approach to cybersecurity that is based on a core concept of "never trust, always verify."
In contrast to traditional models that assume trust after the entrance of an authenticated user into the system. Zero trust requires the authentication and authorisation of every user and device at all times, regardless of location.
Zero Trust should be especially important nowadays, with a majority of the implementations in hybrid and cloud-based infrastructures.
It minimizes implicit accept as true with, which reduces lateral motion throughout IT systems—one of the principal strategies attackers use to take advantage of sufferers' structures, environments, and data. In the context of software development, this approach ensures that security is embedded at some stage in the development lifecycle, similarly strengthening defenses against ability threats.
As reliance on third-party SaaS tools increases, there is a growing need for non-permanent workforces that operate remotely. Therefore, implementing zero-trust network architecture has become imperative in providing a secure environment across dynamic digital landscapes.
Benefits of the cloud revolution
Cloud-based technologies have changed the game for everything from data storage practices to the ability to create entire technology environments.
1. Scalability and flexibility
Organisations can more easily scale a security policy onto the regional or team scale; zero trust policies are easier to enforce and wardrobe secure if all cloud-based architecture.
2. Enhanced visibility
Cloud-based systems provide centralised logs, analytics, and behavioural tracking, which significantly advance anomaly detection capability, the primary business use-case of zero trust network access.
3. Reduce infrastructure spend
No longer locked into key, heavy, and costly security tools, on-prem. Cloud services remove you from "buying" security features, with vendor-built-in security protocols giving you a ground-up approach to the entire zero-trust network architecture.
4. Real-time policy enforcement
Access policies and user alternatives are simple to implement in a real-time fashion, with cloud API services that allow access while still enforcing policies around access that support adaptive security based on user behaviour, device posture, and location.
5. Business continuity
The cloud has proven quite powerful for again embracing a remote work concept by allowing teams to utilise and access data and apps securely, whenever and wherever they need it. This is an intended use of zero-trust architecture.
6. Accelerated time to compliance
Most cloud service providers are now including built-in compliance tools regarding FISMA, HIPAA, GDPR, ISO, etc.
Despite the selected model, we can review and evaluate your equipment, developed to match Gartner's continuous compliance standards, as part of our obligation to support a zero confidence model that improves the year. In a time of Cloud Revolution, this approach ensures that we are ahead of compliance and safety expectations.
How does zero trust network architecture work?
At its core, zero-trust network architecture works by continuously verifying users, devices, and applications before granting access to any resource.
This model relies heavily on multi-factor authentication (MFA), identity and access management (IAM), microsegmentation, and real-time behavioural analytics.
Every request is evaluated based on context—like user identity, location, device health, and the sensitivity of the data being accessed.
If any element is suspicious, access is denied or further verification is required.
Unlike legacy firewalls, zero trust minimises attack surfaces by only allowing the right person the right access at the right time—no exceptions.
Which cybersecurity framework has recently introduced controls for zero-trust architecture?
Several leading frameworks now include controls for zero-trust architecture. The most significant updates have come from:
1. NIST (National Institute of Standards and Technology)
NIST released SP 800-207, a special publication dedicated solely to zero trust. It outlines design principles, implementation scenarios, and security controls focused on zero-trust network architecture.
2. CISA (Cybersecurity & Infrastructure Security Agency)
CISA’s Zero Trust Maturity Model helps federal and commercial organisations plan and implement zero trust network access strategies effectively.
3. ISO/IEC 27001:2022 Update
This recent ISO update includes provisions that encourage granular access controls and identity-first design, key components of the zero trust model.
4. MITRE ATT&CK Framework Integration
MITRE’s framework now incorporates techniques that align with zero-trust assumptions, such as attacker dwell time and lateral movement prevention.
What are the 5 pillars of zero trust network architecture?
To successfully implement zero trust network architecture, organisations need to align with its five core pillars:
1. Identity
This involves rigorous authentication of users and devices through MFA, biometrics, and behavioural patterns. Identity is the first checkpoint, ensuring that only verified individuals get access. Strong IAM systems form the base of a Zero trust architecture.
2. Device Security
Before letting a device connect, the system checks its security posture. Is it patched? Is antivirus running? Regardless of whether it's a mobile device, laptop, or IoT, it will be measured against pre-defined security compliance.
3. Network Segmentation
The network is divided into many small segments to limit the lateral movement of threat actors. Even if a threat actor breaches the network, they only damage a limited amount of resources. With zero trust network access, individuals can only access parts of the network that they are permitted to access based on their role.
4. Application Workload Security
Each application has its own trust boundaries and has its own access policies. Application workloads are monitored for abnormal activity, and access is re-evaluated continuously in real-time.
5. Data Protection
Zero trust encrypts data at rest and in transit. Access is determined based on classification, sensitivity, and user context. This pillar guarantees that critical business and customer data is protected at all times.
What is the future of zero trust network access?
The zero trust network access will look ahead, will be automated, and fueled by artificial intelligence.
According to Gartner, by 2026, approximately 60% of organisations will stop using^16 VPN in favour of ZTNA (Zero Trust Network Access) solutions.
The future of ZTNA will rely heavily on behaviour-based detection^17, continuous monitoring, use of machine learning to address ongoing risks, and risk assessments will be made in real-time. Further, ZTNA will be a highly scalable, context-aware gatekeeper for all of the changes that take place as companies move towards multi-cloud solutions.
ZTNA must adapt to changes in device posture, user behaviour, and information sensitivity. Finally, quantum-resilient encryption and decentralised identity management will also be the future of zero-trust architecture frameworks.
Along with better compliance support and API level control, ZTNA will not only be about protection, but also enabling faster and safer innovation across industries.
