Firewall Deployment
Security and Compliance
Business Firewall Solutions from RJ Cortel Ltd
In today’s digital-first world, where cyberattacks are on the rise and data breaches can cost businesses thousands in both revenue and reputation, a strong firewall is one of the most important components of your company’s IT security posture. At RJ Cortel Ltd, we specialise in providing robust, scalable firewall solutions tailored to the unique needs of each client—whether you're a growing SME or an established enterprise.
We work closely with trusted, industry-leading firewall manufacturers, including DrayTek, WatchGuard, and Netgate, to ensure that your business network is protected from external threats, malicious traffic, and unauthorised access. Our service goes beyond simple hardware supply; we offer complete consultation, configuration, deployment, and ongoing support, helping you stay ahead of evolving threats.
Why Firewalls Are Essential for Modern Business
A firewall acts as the digital gatekeeper of your network, inspecting and controlling incoming and outgoing traffic based on an organisation’s pre-established security rules. In simple terms, it helps stop unauthorised access while still allowing legitimate communication to pass through.
With more employees working remotely or accessing systems from mobile and BYOD (Bring Your Own Device) endpoints, securing the network edge is more crucial than ever.
Without a firewall in place, or with one poorly configured, your internal systems and sensitive data are left exposed to cyber threats ranging from ransomware and phishing attempts to brute-force attacks and unauthorised remote access.
Prevent Data Breaches
Firewalls block harmful traffic before it enters the network, preventing data breaches that could compromise sensitive information. This proactive defense mechanism is crucial for maintaining the integrity and confidentiality of your business data.
Detect and Block Suspicious Behaviour
Modern firewalls detect and block suspicious behaviour, such as port scanning or malware communication. By monitoring network traffic for unusual patterns, firewalls can identify and neutralise potential threats before they cause harm.
Secure Remote Working
As remote work continues to reshape how businesses operate, having secure pathways for employees to access company resources is essential. All of our firewall solutions support modern VPN technologies that enable staff to connect securely, whether they’re at home, on the move, or at a client site.
We help configure and support encrypted connections, split tunnelling, and endpoint policies to ensure your network remains protected without sacrificing usability or speed. Combined with Multi-Factor Authentication (MFA), these setups dramatically reduce the attack surface of your business IT.
Enforce Access Controls
Firewalls enforce access controls within a network, ensuring that only authorised personnel can access specific resources. By segmenting the network, firewalls prevent unauthorised access and potential internal threats, helping secure your assets and data.
Meet Compliance Standards
They can assist you with meeting your compliance standards, such as ISO 27001, Cyber Essentials or GDPR by providing a layer of security that controls the access to sensitive information and monitors the network for violations.
Consultation to Support - A Complete Service
RJ Cortel handles every aspect of the firewall process, from initial consultation to post-deployment monitoring and support. We begin by understanding your current infrastructure, your compliance needs, and any known security issues. From there, we propose a device or solution that’s tailored to your environment—not just in performance but in budget and scalability.
Firewall Options to Suite Every Business
At RJ Cortel, we don’t just throw a product at the problem. We assess your business needs, infrastructure, user count, remote access requirements, and overall threat exposure before recommending a solution. Every business is different, and your firewall should reflect that.
We commonly deploy three types of devices, depending on scale and security demands. Additionally, we offer cloud based and endpoint firewalls to ensure a comprehensive coverage for all scenarios.
-
Ideal for small to mid-sized businesses, DrayTek firewalls offer reliable, cost-effective solutions with excellent VPN capabilities and strong feature sets. With robust WAN failover, Quality of Service (QoS), and content filtering tools, DrayTek routers and firewalls are perfect for businesses that need secure, dependable internet access and remote worker support.
They’re easy to manage and integrate well into hybrid work environments, offering SSL and IPsec VPN functionality for remote access users without the high overhead of enterprise hardware.

For businesses that prefer open-source flexibility and fine-grained control, we recommend Netgate devices powered by pfSense. These solutions are highly customisable and suitable for tech-savvy teams that require deep configuration and traffic shaping options.
Netgate firewalls offer strong performance, a wide range of VPN support (OpenVPN, IPsec, WireGuard), and affordable licensing. They’re a great option for companies who want enterprise-level control without the recurring subscription costs of proprietary systems.

When security and performance are paramount, WatchGuard offers a powerful, enterprise-grade solution. These firewalls come equipped with advanced Unified Threat Management (UTM) features including intrusion prevention, antivirus scanning, application control, and zero-day threat detection powered by AI.
WatchGuard’s Total Security Suite gives businesses deep visibility into network behaviour and offers automated response to detected threats. It’s particularly well-suited to multi-site organisations and those handling sensitive customer or financial data, thanks to its high throughput and comprehensive reporting tools.
