At CETSAT, we take a mature, experienced approach to cybersecurity.
Based in Yeovil and supporting clients across the UK, our cybersecurity experts help organisations prevent data breaches, reduce risk, and stay compliant. We combine enterprise-grade protection with practical support designed around your people and processes.
Every business is a potential target. Research shows that almost half of UK companies experience a cyber attack every year. The question is not if you will be targeted, it is whether you are prepared.
Our goal is to ensure that when a threat appears, your systems resist it, your people recognise it, and your business keeps moving.
The financial, reputational, and operational impact of a cyber attack can be severe. From ransomware and data theft to insider threats, the damage often extends far beyond downtime.
Our in-house cybersecurity team provides protection tailored to your organisation. We deliver vulnerability scans, penetration testing, Cyber Essentials certification, patch management, maintenance, and ongoing monitoring to keep you one step ahead.
We provide fully managed cybersecurity services that safeguard every part of your business infrastructure.
Our partner email gateway. Though Microsoft 365 is a reliable platform, there is much more potential to unlock. Mimecast protects your emails by offering a solid wall of defence, scanning messages before they even hit your inbox. As a result, phishing attempts and malicious attachments are detected and blocked before reaching your users.
Our centrally managed security solution protects your devices against modern threats with minimal impact on performance. By connecting to live threat intelligence databases, we identify and block viruses, ransomware, and malicious files in real time.
Lost or stolen laptops are one of the biggest risks to company data. Our managed encryption ensures every file on your drive remains secure. If a device goes missing, we can remotely wipe it to prevent data exposure.
Outdated software is one of the biggest causes of cyber breaches. Our managed patching service, powered by NinjaOne, automatically installs the latest security updates across every device, keeping your systems safe and compliant.
We monitor patch status in real time, close vulnerabilities quickly and reduce downtime — so you stay secure without lifting a finger.
Traditional antivirus reacts after an attack has begun. ThreatLocker takes a Zero Trust approach, blocking anything not explicitly approved to run. Application whitelisting and ringfencing ensure only safe, authorised programs can execute, drastically reducing your exposure to unknown threats.
We configure, manage and monitor ThreatLocker policies to keep your systems locked down, giving you complete visibility and control over what runs on your network.
Technology alone cannot keep you safe. The strongest cybersecurity comes from combining the right systems with confident, well-informed employees.
We work with organisations across the UK to build security awareness at every level. From cultural assessments and phishing simulations to ongoing staff training, we turn your team into a proactive defence network.
Every business has a different level of risk tolerance. At CETSAT, we help you identify where your greatest risks lie and implement measures that protect you without disrupting operations. Learn more about Cyber Essentials certification.
Using advanced threat analytics and proactive monitoring, our Security Operations Centre (SOC) can detect suspicious behaviour that traditional firewalls may miss. Learn more about our SOC and monitoring solutions.

Here are some of the most common questions we get about managed cybersecurity and compliance.
Cybersecurity protects your systems, data, and people from digital threats such as phishing, malware, and data breaches. For most UK businesses, even one attack can cause days of downtime, financial loss, and reputational harm. Strong cybersecurity keeps your operations secure and trusted.
We offer managed cybersecurity services including antivirus, device encryption, firewalls, vulnerability testing, Mimecast email protection, and Cyber Essentials certification. Our SOC provides 24/7 monitoring and rapid response to threats.
Cyber Essentials is a government-backed UK certification that protects organisations from common online threats. Many tenders and insurers require it. CETSAT can assess your readiness and guide you through to full certification.
Human error causes most security breaches. We provide awareness training and phishing simulations to help your employees spot and stop threats quickly.
Yes. Although we are based in Yeovil, Somerset, we deliver managed cybersecurity services to organisations across the UK through secure remote support.
Costs depend on your organisation’s size and needs. CETSAT designs scalable, cost-effective solutions that provide enterprise-level protection without unnecessary extras.
