Managed Firewall

Make your firewall investment work harder

Energy companies in the industrial sector spanning oil, gas, and renewable energy, play a key role in providing the essential resources needed to power our economies and meet consumer demands.

Building and maintaining an effective cyber security posture is vital in countering today’s threats. It is important to ensure that your defences are multi-layered to minimise your attack surface, make it more challenging for attackers and to increase your ability to detect and respond to threats. You should ensure that each layer is operating effectively, enhance your security posture and enable your business to be resilient to cyber threats.


Firewalls are an essential part of any cyber security posture. Most organisations have them in one form or other, but they can often be overlooked in terms of their efficacy and can cause infrastructure management overheads that prevent you from focussing on other essential activities.

The world has seen an increased shift to home or hybrid working, from on-prem to cloud, and to more complex IT environments. Cyber criminals are becoming more sophisticated as well as increasing the volume of activity against organisations in all industries and sectors. Therefore, it is vital that you ensure your firewall is working hard for you, and that you’re getting a return on your investment, enabling you to focus on your core business.

How Can Sapphire Help

With our team of specialists, Sapphire provides you the skilled resources to not merely install and configure your firewall, but to provide proactive management of them, ensuring the necessary actions are taken before they become a risk.

Aligning with best practice
We will work with your teams to agree the best most stable version of code for your organisation and to align with NCSC best practice.

Proactive 24/7 monitoring and maintenance
We will continuously monitor and maintain your firewall(s) providing regular updates, patching, and rule modifications to ensure optimal performance and protection, avoiding the need for your staff to operate 24/7 or be on-call. We provide a rule modification process that is simple and easy to follow and works with your change control procedures.

Threat mitigation
We can easily connect the Firewall service to our SOC/mXDR service or your third-party providers. Should you or your SOC need us to assist in a ransomware situation, we are available 24/7 to support.

Manage complexity
If your organisation has deployed multiple firewalls across different locations, each firewall having its own set of rules and configurations, it can create a great deal of complexity. Sapphire’s managed service helps efficiently handle that complexity.

Audit and compliance
Regular analysis of firewall rules is an often overlooked but essential aspect of firewall management and compliance with Cyber Essentials/ISO27001/NIST and other regulations. We will ensure compliance with industry standards and best practices through the provision of a well-managed firewall service.
