Protect Your Business With Cross Domain Enterprise Cyber Security Solutions
Cross Domain Solutions allow businesses to securely exchange data between IT, OT, and Cloud environments.
This is crucial for any business that wants to realise the full benefit of digital transformation and AI while strengthening their commercial cyber security.
At 4Secure, we provide enterprise cybersecurity solutions that turn defence into a strategic advantage. We ensure secure data flows, regulatory compliance, and operational resilience.
Commercial Cyber Security Measures from 4Secure
4Secure provides specialist enterprise cyber security solutions for industries where secure data exchange, network separation, and operational resilience are essential. Our approach is vendor-agnostic and tailored to the specific requirements of your environment and risk profile.
Cross Domain Solutions
Cross Domain Solutions enable controlled, policy-enforced data exchange between networks with different security requirements. 4Secure solutions inspect, filter, and validate data before it crosses the boundary, helping you prevent data leakage and malicious content while maintaining essential information flows.
Our Cross Domain Solutions can support both bidirectional and unidirectional data flows, making them suitable for use cases ranging from secure information sharing to IT/OT integration and critical infrastructure.
TrustedFilter®
TrustedFilter® is 4Secure’s secure-by-design data transfer software. It normalises, inspects and verifies data at the content level, while providing data transformation and policy enforcement across environments with different security requirements. It can be deployed on-premise or in the Cloud and can work alongside existing security controls.
For commercial businesses, TrustedFilter® can help secure data flows across financial services, OT, and critical infrastructure environments while supporting compliance and operational resilience.
Data Diodes
Data diodes enforce one-way data transfer at the hardware level, maintaining physical separation between networks. They are particularly useful where you need to move operational or security data out of a protected environment without creating a route back into it.
4Secure designs Cross Domain Solutions around data diodes where unidirectional transfer provides the appropriate level of assurance, with TrustedFilter® available to add content inspection, validation, and transformation capabilities.
IT/OT Secure Connection
As your business connects operational technology to IT networks, you need to balance data access with the security requirements of critical systems. 4Secure provides controlled, policy-enforced IT/OT data exchange using hardware-enforced security, intelligent data filtering, and protocol inspection.
This enables you to gain greater visibility from your OT environments while limiting the cyber risks associated with connecting previously separated networks.
BUSINESS BENEFITS
The Business Benefits of Strong Commercial Cyber Security
4Secure helps strengthen your commercial cyber security by securing the boundaries between networks, controlling how data moves, and applying security controls to the information being transferred.
Reduce Cyber Risk
Controlling how data moves between different environments can reduce the opportunities for malicious content, unauthorised access, and data leakage, helping to avoid a cyber incident. 4Secure’s Cross Domain Solutions inspect, verify, and control data before it crosses network boundaries, while data diodes can enforce physically one-way data flows where required.
Support Regulatory Compliance
If your business operates in regulated industries, you need to demonstrate that sensitive information is properly protected and that security controls are appropriate to the risks they face. 4Secure’s solutions help you enforce defined data-transfer policies and maintain secure separation between environments, supporting compliance requirements across commercial and critical infrastructure settings.
Maintain Operational Continuity
Security measures should not prevent critical systems from receiving the information they need. 4Secure enables controlled data exchange between IT, OT, and other environments, helping your business maintain visibility and connectivity while protecting critical systems from unnecessary exposure to cyber threats.
Enable Secure Digital Transformation
Connecting previously separated environments can create opportunities for better visibility, analytics, and automation, but it can also introduce new security risks. By securing data flows between IT, OT and Cloud environments, 4Secure helps you adopt new technologies without compromising the security of critical systems.

Unbeatable Outcomes
For Critical National Infrastructure (CNI), Operational Technology (OT), and finance, cybersecurity is a strategic enabler as well as protection. A strong security posture can unlock new opportunities, streamline operations, and build trust with stakeholders. At 4Secure, we help organisations move beyond compliance and defence, delivering security that drives commercial and operational success. Our solutions provide three key outcomes:
Compliance as a Strategic Advantage
Regulatory requirements such as NIS2, ISO 27001, and industry-specific cybersecurity standards demand rigorous security measures. Rather than treating compliance as a box-ticking exercise, we help organisations integrate security into their operations, making compliance a business strength.
A well-secured organisation not only avoids penalties and reduces the chance of a data breach, but builds trust, secures contracts, and differentiates itself in competitive markets.
Resilient and Uninterrupted Operations
Cyberattacks and system failures can cause operational downtime, financial loss, and reputational damage. Our IT-OT security solutions provide segmented, secure, and highly resilient architectures, ensuring that critical systems remain operational.
This means businesses can reduce risk, maintain service continuity, and gain a competitive edge by proving their security maturity to regulators and partners.
Secure and Controlled Data Flow
Real-time data exchange is critical for operational efficiency, but uncontrolled data movement introduces cyber risks. Our Cross Domain Solutions and data diodes ensure secure, policy-enforced data transfer, allowing organisations to leverage data securely across networks.
This not only reduces risk but also enables faster, safer decision-making in highly regulated environments.
Sectors We Protect From Cyber Attacks
Our work spans across industries as diverse as telecommunications to government contracting, from banking and military applications to SMEs and somewhere in between.
