Identity
Who is requesting access.
ZERO TRUST & SECURE ACCESS
Do not trust location alone. Verify the context before granting access.
Users, applications, devices, and data no longer exist within a single perimeter. They are distributed across offices, Data Centers, cloud, mobile devices, remote work, and third-party environments.
In this scenario, being connected to the corporate network should not be enough to establish trust.
Add Solution designs Zero Trust and secure access architectures that combine identity, device, context, least privilege, segmentation and policies so that each user can access what they actually need—under the right conditions.

THE PERIMETER HAS CHANGED
Applications and users are no longer concentrated behind a single boundary.
Offices, home offices, branches, cloud environments, SaaS, data centers, partners and mobile devices form a distributed environment. The assumption that ‘inside is trusted; outside is not’ is no longer sufficient for many scenarios.
REMOTE USER → APPLICATIONS ← CLOUD · DATA CENTER · CORPORATE NETWORK
A network address indicates where a connection came from. It does not necessarily indicate whether it should be trusted.
ARCHITECTURE, NOT PRODUCT
Zero Trust is a security architecture, not a feature to be enabled.
Identity, MFA, device trust, NAC, ZTNA, PAM, segmentation, firewall, endpoint, observability, and SIEM can all play a role. No single control represents the entire architecture.

Zero Trust cannot be bought with a license. It is built by integrating controls.
VERIFY EXPLICITLY
The decision must use more context than simply a username and password.
Identity, MFA, device, location where relevant, behavior, requested resource, risk and security posture can provide signals—depending on the capabilities available in each architecture.
Device
Which device participates in the connection.
Context
Conditions relevant to that request.
Resource
Which application or service will be accessed.
Need
Why access is needed and with what privilege.
IDENTITY + DEVICE + CONTEXT + RESOURCE → POLICY ENGINE → ALLOW / RESTRICT / DENY
Authenticating someone does not mean authorizing access to everything.
Least privilege grants only the necessary resources, in the necessary context, with continuous review according to the architecture.
Identity answers who someone is. Authorization answers how far that identity can go.PAM & Identity Security
Secure architecture must also consider the possibility that a control has already failed.
Compromised credentials or endpoints, unauthorized sessions, untrusted devices, and lateral movement require reducing reach, limiting privileges, expanding visibility, and containing impact.
The question is no longer just “how do we prevent entry?” but also “how far could someone get if they got in?”.
When the perimeter is distributed, identity becomes more important in the access decision.
Users, groups, roles, MFA, service identities where relevant, context, and policies help guide each decision.
PAM & Identity SecurityA valid identity on an unknown device may represent a different context.
Corporate, managed, or BYOD devices, posture, certificates, compliance, and endpoint security can provide signals when supported — without independently guaranteeing a secure endpoint.
Network Access Control (NAC) Endpoint SecurityThe user needs access to the application. Not necessarily the entire network.
Zero Trust Network Access can provide more granular access to applications and resources depending on the architecture.
USER → IDENTITY + CONTEXT + POLICY → AUTHORIZED APPLICATION
Application access and network access do not have to mean the same thing.
A VPN creates a secure channel. Zero Trust questions what should pass through that channel.
A VPN protects communications and provides connectivity according to the architecture. Zero Trust adds verification, context, least privilege and access restrictions. A VPN may remain part of certain environments.
Network Security & FirewallLeast privilege must also exist between networks and applications.
Users, servers, workloads, applications, IoT, environments, and zones can be segmented to reduce unnecessary paths and limit lateral movement — without claiming to eliminate it.
Network Security & FirewallNAC controls admission. Zero Trust expands the trust model.
NAC helps answer who or what is entering the network. Zero Trust extends the decision to what that identity or device should access, in what context, and under what conditions.
Network Access Control (NAC)The greater the privilege, the greater the control over access should be.
Administrators and privileged accounts can reach servers, network devices, firewalls, cloud environments, and critical systems. PAM can add vaulting, approval, session control, auditing, and least privilege, depending on the platform.
PAM & Identity SecurityGiving access to a vendor should not mean placing them inside your infrastructure.
Contractors, support teams, vendors, consultants, and temporary staff need individual identities, MFA, specific resources, defined timeframes, context, least privilege, and auditing.
Third parties need access to the service they support, not necessarily to the network that hosts it.
Access can terminate at the authorized resource without necessarily exposing the entire network.
Applications on premises, in a data center, in the cloud or in hybrid environments can be made available through a chain of identity, policy and secure access.
USER → IDENTITY → POLICY → SECURE ACCESS → PRIVATE APPLICATION
Cloud distributes resources. The trust model needs to follow that distribution.
Identities, workloads, applications, services, administration, remote users, and hybrid environments must be part of the architecture.
Cloud PAM & Identity SecurityAdministering infrastructure requires greater trust—and should therefore require greater control.
SSH, RDP, consoles, firewalls, switches, servers, cloud, and critical systems require identity, MFA, PAM, session, auditing, privilege, and time.
PAM & Identity SecurityA trust decision must leave evidence.
Authentications, access, failures, devices, context changes, policies, sessions, and events gain value when correlated across controls.
SIEM & SOC AI & ObservabilityLEGITIMATE ACCESS
Security should not make every legitimate access attempt an obstacle.
Security, experience, productivity, and operations must coexist. Policies should reflect risk and context.
The goal is not to make legitimate access more difficult. It is to reduce unnecessary trust.
ZERO TRUST JOURNEY
Zero Trust is usually an evolution, not a weekend migration.
Organizations start at different levels of maturity. A phased implementation avoids a “big bang” change and allows each stage to be validated.

ASSESSMENT
Before implementing Zero Trust, we need to understand where trust exists today.
The assessment relates trust, risks, and priorities to build a roadmap compatible with the organization's reality.

Cybersecurity Technologies & ProductsPERGUNTAS FREQUENTES
Decisões importantes sobre Zero Trust & Acesso Seguro
Respostas objetivas para dúvidas técnicas e operacionais que costumam surgir antes de um projeto.
01Zero Trust é um produto?
Não. É uma arquitetura construída pela integração de controles, políticas e processos.
02ZTNA substitui VPN?
Não em todos os cenários. ZTNA pode granularizar o acesso a aplicações, enquanto VPN pode continuar fazendo parte de determinadas arquiteturas.
03MFA é suficiente para implementar Zero Trust?
Não. MFA fortalece a autenticação, mas Zero Trust também considera dispositivo, contexto, recurso, risco, política e menor privilégio.
04NAC faz parte de Zero Trust?
Pode fazer. NAC controla a admissão à rede; Zero Trust amplia a decisão sobre o que uma identidade ou dispositivo pode acessar.
05Zero Trust bloqueia todo acesso?
Não. O objetivo é permitir o acesso legítimo com o contexto e o privilégio adequados, reduzindo confiança desnecessária.
