Zero Trust: the security model to protect the business in the hybrid era

Zero Trust has stopped being a concept confined to technical discussions and now occupies space on the executive agenda. That happens because the traditional "perimeter", the idea that the company is safe inside four walls, no longer answers the current business environment.

With distributed users, cloud applications and diverse devices, security has to keep up with the operation without creating bottlenecks. The logic now is: nobody should be trusted by default, even when already connected to the corporate network.

This change answers a concrete need. Risk goes beyond external attacks and includes compromised credentials and excessive access by employees or partners.

When the company relies on blind trust in whoever is "inside", any small gap can paralyse the entire operation. With a continuous verification architecture, the impact of an incident is isolated and minimized.

Why Zero Trust became a strategic priority

Adoption of this model is tied to the transformation of infrastructure. The network is no longer a fixed place. Today, identities, applications, APIs and outsourced services make up a much wider attack surface.

In practice, controls based only on firewall and VPN (static borders) are no longer enough. The current challenge is to make sure every access is authorized based on context: who is accessing, from where, through which device and why they need that data now.

For the company, Zero Trust is an insurance policy against the interruption of productivity. Among the factors accelerating this change are:

• Expansion of remote and hybrid work;

• Growth in the use of cloud software (SaaS);

• Increase in attacks focused on password theft;

• The need to meet LGPD and other regulatory requirements;

• Frequent integration with suppliers and third parties.

The pillars of Zero Trust in identity management

In this architecture, user identity is the new perimeter. Access is not granted just because the password is correct, but after validating multiple factors: location, time, usual behaviour and device health.

That requires what we call Least Privilege: the employee only has access to what is strictly necessary for their role.

In practical terms, if an HR consultant is hacked, for example, the attacker will not reach financial data or the engineering server. That is because access is segmented and monitored in real time.

Reducing the impact of intrusions: the barrier against lateral movement

One of the great dangers in modern attacks is an intruder being able to "circulate" freely between systems after the first entry. Zero Trust fights that through microsegmentation.

Picture a ship with watertight compartments: if there is a leak in one section, the others stay dry. Zero Trust does the same with your company data.

Even if a breach occurs, it meets technical barriers that restrict its progress. That reduces what we technically call the "blast radius", protecting the strategic core of the business.

On top of that, visibility reaches another level. Monitoring stops looking only at the "entry doors" and starts following internal behaviour, making it easier to detect anomalies before they become a serious incident.

How to deploy the model without "locking up" company productivity

A common mistake is treating Zero Trust as an off-the-shelf project or an isolated tool. Efficient implementation happens in phases, making sure security does not become an obstacle for the people who need to work.

A consistent maturity journey follows this logic:

1. Mapping: understand who the users are and where the critical data is;
2. Classification: separate what is essential from what is secondary;
3. Strong authentication: implement extra validation layers (such as MFA);
4. Segmentation: create barriers between departments and applications;
5. Continuous monitoring: use intelligence to identify out-of-pattern access.

The secret to not paralysing the company is the balance between protection and usability. A well-designed Zero Trust is almost invisible to the legitimate user, yet impassable for the bad actor.

How AKEN structures Zero Trust architectures

Implementing this model demands more than technology; it demands architectural vision and diagnosis.

That is where AKEN acts strategically. Our consultancy structures projects based on the reality of each company, whether it is a multi-site operation or a fully remote team.

We do not deliver a generic checklist, but a security roadmap that evolves as your business grows.

The work of AKEN ranges from assessing identities to defining policies that make sense for the daily operation. The result is a resilient company that does not fear innovation or the opening of new work fronts, because it knows its technology base is protected by a model of constant verification.

Frequently asked questions about Zero Trust

1) What is the Zero Trust model in practice?

It is a security approach in which no access is trusted automatically. Everything has to be verified, validated and monitored, regardless of where the access request comes from.

2) Will this make my employees access slower?

No, when it is well planned. On the contrary: conditional access and Single Sign-On (SSO) technologies can even make the day easier, removing the need for slow, unstable VPNs.

3) My company is mid-sized. Is Zero Trust for me?

Definitely. SMBs are frequent targets because they have simpler defences. Zero Trust lets smaller companies reach the same level of protection as global giants, starting with what is most critical.

4) Do all current computers and systems have to be replaced?

No. The model can be applied gradually to existing (legacy) systems, starting with the identity layer and access to the most important servers.

5) How does Zero Trust help with LGPD compliance?

By strictly controlling who accesses personal data and recording every interaction, the company meets several governance and data protection requirements demanded by the law.

6) What is the first step to start?

The initial step is diagnosis. You need to understand your data flows and who the users with the highest privileges are. AKEN can run that initial assessment to design the ideal journey for your scenario.
