Cyber Security Services for Businesses in Northern Ireland
Cyber security is no longer only an IT concern. It's a business risk that needs to be actively managed.
3PS provides managed cyber security services for SMEs across Northern Ireland. We help protect your systems, devices and users through ongoing management rather than waiting for an incident to happen.
From firewall and endpoint protection to security monitoring, staff training and penetration testing, our services work together to reduce risk and support the way 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 an ongoing approach to protecting your business. Firewalls are maintained, endpoints are secured and important updates are applied to reduce avoidable weaknesses.
This reduces your exposure to phishing, ransomware and unauthorised access while helping your systems remain stable as your business changes.
When issues do arise, they are handled quickly and properly - but the focus remains on prevention.
How We Protect Your Business
Firewall Management
We manage your firewall settings, security rules and updates to control access to your network and block unwanted traffic. Regular reviews help keep protection aligned with your systems, staff and changing business needs.
Endpoint Protection
Endpoint detection and response helps protect your computers and servers from malware, ransomware and suspicious activity. We manage the protection across your devices and investigate threats that traditional antivirus may miss.
Threat Detection
24/7 managed detection and response adds expert oversight to your security technology. Suspicious activity is investigated quickly, helping contain genuine threats before they cause wider disruption to your business.
Cyber Security Training
Practical training helps your staff recognise phishing emails, suspicious links and common social engineering tactics. Regular testing reinforces good habits and reduces the likelihood of an avoidable mistake becoming a security incident.
Account Security
We protect Microsoft 365 and Google Workspace accounts with multi-factor authentication, access controls and permission management. This helps prevent stolen passwords from exposing your email, files and business data.
Penetration Testing
Controlled testing identifies weaknesses that an attacker could use to gain access to your systems. You receive clear findings and prioritised recommendations, helping you address the most important risks first.
Security That Supports Compliance
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 Built on Recognised Standards
Cyber security needs to be consistent, structured and accountable.
ISO/IEC 27001 Certified
3PS is certified to ISO/IEC 27001, the internationally recognised standard for information security management.
Our security processes and risk controls are independently audited within the scope of our certification. This provides external assurance that information security is managed through documented policies, responsibilities and ongoing review.
Applying the Same Discipline to Your Business
We bring the same structured approach to the environments we manage for our clients.
This helps businesses improve oversight, understand their risks and maintain security controls that are properly documented and regularly reviewed.
Who we support
Cyber security should be actively managed, not installed once and forgotten.
We work with SMEs of 10 to 250 employees that rely on technology to keep operating. They get the security expertise and oversight they need without the cost of a dedicated in-house team.
Based in Northern Ireland, 3PS supports organisations across the UK and Republic of Ireland.

Why Businesses Choose 3PS for Managed Cyber Security
Cyber security is most effective when it is managed consistently as part of your wider IT environment.
We bring security into everyday IT management, helping clients understand what is protected, where improvement is needed and how risks are being addressed.
Consistency Over Time
Security needs change as your business changes. We review and improve controls over time, with clear communication so you understand the work being completed and the risks being addressed.
Better Visibility, Fewer Surprises
Better visibility makes it easier to identify weaknesses and prioritise improvements. This helps reduce unexpected issues and gives your business a clearer view of its current security position.
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.
