How

Cyber Security

benefits your business

Threat awareness

We proactively monitor, detect and respond to cyber incidents — stopping problems before they escalate.

Secure access & identity controls

We implement multi-factor authentication, role-based permissions and robust identity governance so only the right people have access.

Vulnerability & patch management

Regular assessments, updates and hardening keep your systems secure and compliant.

Rapid incident response

If a breach happens, our experts act swiftly to contain it, minimise damage and restore normal operations.

Cyber Security

Cyber threats aren’t waiting — and neither are we.


With our Cyber Security service, you’ll get comprehensive, expert-led protection for your entire IT estate — from endpoints and servers to networks and cloud applications. We make sure your business stays secure, compliant and prepared for whatever’s next.

We handle everything from threat detection, access management and vulnerability assessment to incident response and ongoing maintenance. Our team uses advanced tools and best-practice processes to identify risks before they become issues — so you can focus on growing your business with confidence.

Our approach is personal, pragmatic and tailored to your business. You’ll get a security plan that fits your needs, clear reporting so you know what’s happening, and real engineers who speak plain-English, not jargon.

What is Cyber Security?

Cyber Security is the framework and ongoing process of safeguarding your systems, data and users from internal and external threats.

It includes everything from secure configurations and user access controls to real-time monitoring and incident response.

At 39D, we wrap all these elements into a managed service — meaning you don’t need to piece together multiple vendors or rely on reactive fixes. Instead, you get a proactive security posture that's integrated with your broader IT support strategy.

This service is ideal for organisations that:

  • Process sensitive data (personal, financial, or regulated)
  • Have remote, hybrid or multi-site teams relying on network access
  • Want to move from “firefighting” to proactive security management
  • Are tendering for contracts that require certified security compliance (e.g., Cyber Essentials Plus)
  • Need better visibility of risk, vendor controls and incident readiness

Answer

What does managed cyber security actually cover?

Our service covers threat monitoring, access control, vulnerability assessments, incident planning and response, security updates, user awareness and reporting — all wrapped into one managed package.

Is this service only for large businesses?

Not at all. We work with small and mid-sized UK organisations, tailoring our security offering to your size, risk profile and operational needs — so you get the right level of protection, not over-engineered complexity.

What’s the difference between Cyber Essentials and Cyber Essentials Plus?

Cyber Essentials is an effective baseline certification that covers basic cyber hygiene and helps you protect against common threats. Cyber Essentials Plus includes all those controls and adds hands-on technical testing and audit of your systems.

How quickly can you get us covered?

After an initial assessment we’ll agree a roadmap and timing. While full implementation depends on scope, many clients see key protections in place within weeks — then we build ongoing monitoring and improvements from there.

What happens if we experience a cyber incident?

We’ll activate our incident response procedures: we’ll contain the threat, begin recovery, communicate with stakeholders (if needed), and review what happened to strengthen your defences going forward.

Our clients say...

Cannot recommend this company highly enough. Matthew talked me through an IT issue I was having patiently and professionally and all was corrected within just a few minutes. I am a total technophobe so was worried I wouldn't understand what I was being told, I was totally wrong. Clear, precise and in terms even I understood. Would definately use this company again. Five star service.

39D IT Support is so useful for me in my everyday life running a small business. I can call any time to ask for help with my computer systems and someone knowledgeable will answer politely and efficiently. Their service, in my opinion, is second to none. John

We've been using 39D for IT Support for 2.5 years now and they've been absolutely brilliant. They do everything from setting up new equipment, troubleshooting an issue, or offering advice on the best solutions for my business and they're always professional and reliable. Would definitely recommend them to anyone looking for solid IT support.

Matthew and his team have been solving our problems here at Rainbow Estate Agents successfully for the past 5 years or so. No reason to complain and happy to recommend
Alex Smith
This company goes above and beyond to support its clients. Being one of them i have never experienced a more robust support when it comes to IT infrastructure. The advice they give is honest and trustworthy and the speed in which they deliver the ongoing support is amazing. I would highly recommend anyone who is not happy with their current arrangements to contact the team at 39D. If you are yet to invest in protecting your businesses online presence, then make this company your first point of contact.
Sean Hewitt
We have just moved to 39D and I have been VERY impressed with the service we are receiving. Considering we had a huge data merge to undertake they have been patient, quick and very knowledgeable. In particular Matthew, Jake and Chloe have been extremely helpful. We are looking forward to their continued service and expertise.
Tracy Askew
Having a major breakdown on sending and receiving emails. Which is a clearly a problem when running your own business. Also with numerous issues with my IT, I finally decided to try 39d. I was a little apprehensive - I had paid two different companies to try and rectify my problems. Within a morning my emails and IT had been resolved I have now signed up to D39. I can�t tell you how relieved to know that should I have a problem I just have to call D39 and they are there at the end of the phone. Matthew explains in terms I can understand. Highly recommended.
