Looking after your data, infrastructure and people
is a 24/7 job. Trust our experts to do it right.


If businesses want to avoid leaving themselves vulnerable to a breach, the onus is on them to approach their security holistically. In many sectors, not having adequate security protocols in place not only puts you at risk of reputational damage; it can even put you on the wrong side of the law.

We take your business security incredibly seriously. Over our years of honing our security services, Node4 has developed a multi-faceted approach, which equips you with the tools to avoid, recognise and respond to threats. We can provide an all-round assessment of your existing security posture, offer expert guidance to you over a window of time, or even take on your security operations ourselves.

Whatever level of support you opt for, you can operate safe in the knowledge that you are complying to industry regulations, your employees will be kept security savvy and threats will be monitored around the clock, giving you peace of mind in all aspects of your business. 

Below are the main areas of security that we cover. To find out more about anything you see here or to speak to our security consultants about reducing your risk, get in touch.



Many businesses simply don’t have the resource to dedicate to full-time, senior security personnel, but we don’t think that should be a barrier to you accessing superior security services. Our business advisors will supply leadership and expertise, as well as providing an objective evaluation of your security operations.

We recently helped AdviseInc to evaluate their infrastructure, adapt to the evolving cyber security landscape and ensure their data remained as secure as possible.

Advise Inc


Securing your business begins with insight and expertise, but to put it into practice, industry-leading technology is required. We are certified suppliers of next-generation technology solutions which will protect you from unforeseen disruptions and fortify your borders against threats, both outside and within your organisation.

An open and trusting nature is beneficial for your business, but it also brings significant risk. Read this blog from Glenn Akester, Technology Practice Lead, to learn more.



As the technology that enhances your business advances, so does the technology that can be used against it. Failing to confront this reality can put your staff, customers and valuable data at real risk. At Node4, we provide a range of services designed to inform you about the threats you face and put safeguards in place to prevent them before they strike.

Staying on top of ever-changing data privacy regulations is a challenge for every business, but there is more to remaining compliant than simply adhering to the minimum government standards. We can help you stay privacy compliant with the full compliment of technical, physical and administrative security protocols.


Our team of experienced Chief Information Security Officers provide a cost-effective approach to improving your security posture, with your virtual CISO advising on governance, risk management, security testing and incident response. They operate based on what you need, whether that’s unbiased guidance, direction or control to bring you the level of protection that you need in line with your enterprise programmes, company policy and business objectives.


Cyber Essentials is a UK scheme aimed at all businesses and is generally regarded as essential for any businesses serving UK Government. We can help you to prepare for certification and manage the certification process for Cyber Essentials and Cyber Essentials Plus. Cyber Essentials is managed and governed by NCSC the UK Government National Cyber Security Centre. 


One advantage of using a managed service like ours is being able to use best practice and experts who work on a variety of IT infrastructures day in day out. Without compromising customer security, we look at trends and vulnerabilities and investigate your infrastructure from the outside and the inside using the “lens” which hackers would use.

“The solution provided by Node4 means we no longer need to worry about hardware faults and can address more pressing issues to help move the business forward.

In the event of a disaster, we can be up and running again within an hour – without doing any of the ongoing maintenance or running updates in the meantime.”



Our recent research on mid-market IT priorities shows time and time again that data privacy is the top priority for most businesses. One of the very real and complex threats impacting these businesses is called phishing.
