Secure remote work and zero trust network access (ZTNA)

Secure remote work and zero trust network access (ZTNA)

Protection of remote access to users and corporate resources through ZTNA and Secure Workspace schemes.

Home/Services/Secure Remote Work

What it is and what it is for

Secure remote work and Zero Trust Network Access (ZTNA) solutions ensure that distributed employees and hybrid teams can securely connect to company servers, cloud workloads, and sensitive applications from anywhere, with contextual identity validation, granular device posture checks, and continuous encrypted access controls without exposing internal network subnets.

Secure remote work connectivity and ZTNA architecture

We replace indiscriminate VPN network bridges with least-privilege, application-level Zero Trust micro-tunnels:

  • Direct application-level routing to cloud or on-premise workloads without ever exposing the underlying corporate network infrastructure.
  • Continuous endpoint health and posture verification (active EDR, updated OS, BitLocker encryption) prior to granting application session access.
  • Adaptive Multi-Factor Authentication (MFA) with biometric push challenges and risk-based geolocation validation preventing credential abuse.
  • Application-specific encrypted micro-tunnels eradicating lateral movement vectors between remote users and internal server subnets.

Enterprise Remote Security with Sophos and WatchGuard

We engineer remote access architectures that deliver rigorous enterprise defense alongside frictionless user productivity:

  • Sophos ZTNA: Native integration with Sophos Intercept X endpoints, instantly revoking application access if endpoint malware is detected.
  • WatchGuard AuthPoint & Mobile Security: Enterprise MFA and robust encrypted gateways featuring push-based verification and mobile risk policies.
  • Unified identity synchronization with corporate identity providers (Microsoft Entra ID, Google Workspace, Okta, Active Directory).
  • Comprehensive session auditing, real-time access telemetry, and compliance logging for regulatory alignment.

Who this service is for

Companies in the legal, healthcare, education, professional services, manufacturing, and retail sectors that lack an in-house security team and support hybrid or remote staff connecting from public and home networks.

What ORIT delivers

  • ZTNA architecture design and rollout replacing legacy corporate VPNs with least-privilege application access.
  • Mandatory Multi-Factor Authentication (MFA) enforcement across all remote entry portals and cloud services.
  • Device posture validation policies verifying endpoint antivirus, OS patches, and disk encryption prior to connection.
  • Granular application-level access controls preventing lateral threat movement within the corporate environment.
  • Remote connection logging and behavioral auditing identifying suspicious login times and abnormal geographical locations.

How we work

1
Phase 1 - Remote access and role assessment: mapping required corporate tools and data sets across workforce roles.
2
Phase 2 - Identity management and MFA hardening: securing identity directories and implementing second-factor authentication.
3
Phase 3 - ZTNA connector deployment: publishing internal enterprise applications without opening perimeter firewall ports.
4
Phase 4 - Endpoint client rollout and user onboarding: guided configuration and employee training for safe connection habits.
5
Phase 5 - Continuous adaptive security: refining contextual access rules and continuously assessing remote device health.

Business Benefits

  • Secure enablement of mobility and teleworking.
  • Access to corporate resources without exposing the internal network.
  • Access control based on identity and device status.
  • Smooth and secure user experience from anywhere.

Frequently Asked Questions

Why is ZTNA superior to a traditional VPN?
A traditional VPN grants broad access to the entire internal network upon authentication. ZTNA enforces the principle of never trust, always verify, providing access strictly to the single application required for the user’s role.
What happens if an employee connects from an infected computer?
ZTNA posture policies evaluate device health before granting access. If the endpoint lacks active antivirus or security patches, access to corporate applications is automatically denied.
Is Multi-Factor Authentication (MFA) mandatory?
Yes. Implementing MFA neutralizes over 99% of identity-based cyberattacks, credential stuffing attempts, and phishing attacks targeting remote workers.
Does secure remote work software slow down employee computers?
No. Modern lightweight ZTNA connectors optimize traffic routing directly to cloud services and corporate resources, providing a seamless user experience.
