Cyber Security Services for Businesses in Northern Ireland
Cyber security is no longer just an IT concern. It's a business risk that needs to be actively managed.
At 3PS, we provide practical, structured cyber security services for small and medium-sized businesses across Northern Ireland. Our approach is built around managed cyber security - meaning we actively reduce your risk over time, rather than simply responding after something goes wrong. From firewall management and endpoint protection to security monitoring, user awareness training and penetration testing, we deliver layered network security services that align with how your business operates.
Proactive Cyber Security — Not Just Reactive Protection
Effective cyber security isn't about reacting after something goes wrong. It's about reducing the chances of it happening in the first place.
We take a proactive approach by continuously managing the systems that protect your business. Firewalls are monitored and maintained, endpoints are secured, patches are applied promptly and emerging risks are identified through ongoing security monitoring - before they become incidents.
This reduces exposure to common threats such as phishing attacks, ransomware and unauthorised access, while ensuring your systems remain stable and secure as your business grows.
When issues do arise, they are handled quickly and properly - but the focus remains on prevention.
What Our Cyber Security Services Cover
Firewall Management
We provide a fully managed firewall service, ensuring your infrastructure is correctly configured, kept current and aligned with best practice. Rules are reviewed regularly, risks are addressed promptly and your network perimeter stays properly controlled.
Endpoint Protection & Device Security
We deploy and manage endpoint protection across all your devices - desktops, laptops and servers - with managed security that defends against malware, ransomware and unauthorised access. Devices are kept updated, secured and aligned with Cyber Essentials requirements as standard.
Security Monitoring & Threat Detection
We provide continuous security monitoring across your key systems and endpoints. Unusual behaviour is flagged, emerging threats are identified early and action is taken before they escalate - giving you visibility and response capability that most SMEs don't have on their own.
Cyber Security Awareness Training
We deliver practical cyber security awareness training that helps your staff recognise phishing emails, suspicious links and common social engineering tactics. The goal isn't box-ticking - it's building genuine awareness that reduces the likelihood of a costly human error.
Penetration Testing & Vulnerability Assessment
We carry out and coordinate penetration testing and vulnerability assessments to identify security gaps across your environment - with clear, prioritised recommendations on what to address and how.
Security That Supports Compliance and Business Requirements
For many businesses, good cyber security and compliance aren't separate concerns — they go hand in hand. The controls we put in place to protect your systems are the same ones required by Cyber Essentials, making certification a natural outcome of good security management rather than a separate workstream.
Security-Led IT Support Backed by Recognised Standards
Cyber security needs to be consistent, structured and accountable.
ISO/IEC 27001 Certified
3PS is fully certified to ISO/IEC 27001 - independently audited and verified against the internationally recognised standard for information security management. Our internal risk controls, processes and governance meet a level of rigour that most providers simply don't operate to.
The same discipline, applied to your business
We apply that same structured discipline to client environments - helping businesses build better governance, improve risk awareness and implement security practices that actually hold up under scrutiny.
Who we support
We work with SMEs across the UK that need more than basic antivirus and a firewall they set up years ago. Typically, organisations with between 10 and 250 employees - businesses that handle sensitive data, depend on their systems and can't afford a serious security incident. Based in Northern Ireland, we support clients throughout the UK and Republic of Ireland.

Let's Review Your Cyber Security
If you're not confident your current cyber security setup would stop a determined attacker - or simply aren't sure where you stand - it's worth finding out before a problem forces the issue. An initial conversation allows us to assess your environment, identify risks and highlight where improvements can be made. You'll come away with a clear, honest view of your current security posture - and a practical sense of what needs to change.
FAQ's
Let's get through them together.
At a minimum: firewall protection, endpoint security, monitoring and staff awareness training - all properly managed, not just switched on and forgotten. Most SMEs have some of these in place; fewer have all of them working together effectively. That gap is where most incidents happen.
Honestly? Most businesses don’t know until they’re tested. A structured security review assesses how your systems are configured, how they’re managed day to day and where the real risks are - giving you a clear, evidence-based view rather than assumptions.
Less than you might think - and significantly less than the average cost of a breach. Effective cyber security for SMEs is scalable and practical. We focus on the controls that make the biggest difference to your risk profile, without unnecessary complexity or cost.
Yes - and that’s deliberate. Security built into how systems are managed daily is far more effective than security treated as a separate service. For clients on our managed IT support, protection is continuous and consistent, not periodic.
