Most businesses hope their security posture will hold up against a cyber attack.
We make sure you're in safe hands.
Our free cyber security review checks the four places small businesses are most often caught out, then gives you a clear, prioritised action plan in plain English.
Do you know how exposed your organisation really is?
A cyber security review will give you the data you need to understand your current risk position.

Cyber threats now target every part of your organisation. Our cyber security review will evaluate user identities, roles, policies and cloud environments, highlighting vulnerabilities, gaps, and improvement opportunities.

We'll share the results of our cyber review with you, identifying areas of risk, and we'll discuss a roadmap to improve your security posture.

Our FREE cyber security review focuses on the four areas where most attacks succeed: Microsoft 365 and email security, user access and admin roles, device security and updates, and backups.
Together, these checks give you a complete picture of where your business is exposed, and a clear, prioritised starting point for fixing it.
Could a stolen password give someone access to your business?
We review multi-factor authentication (MFA), sign-in protection and email filtering, so phishing and account takeover are far harder to pull off.
Who can access what?
We look for dormant accounts and leavers who may still have access.
We'll also review where too many admin roles and permissions are in use and any signs of business email compromise (BEC).
Are your laptops and phones patched, protected and recoverable?
We check that devices are up to date, secured against threats and can be recovered if lost, stolen or infected.
Is your backup strategy fit for purpose?
We check that the right data is backed up, that it can really be restored, and how quickly you could get back to work.
Our free cyber security reviews are designed to take less than 24 hours from start to finish. Once we have gathered the initial information we will complete the assessment and arrange a call to go through the results and provide you with a usable roadmap.
We need read-only access to your Microsoft 365 environment, and we'll spend time asking questions about your IT environment. We can't change any settings, and you stay in complete control of what we see.
Yes. We only use your details to carry out the assessment, and we don't share them with anyone else.
Antivirus only covers one small part of your security. System 15 looks at how your accounts, permissions, devices and backups work together, because that's where most real problems start. We call it defence in depth, as a single solution can't provide complete protection.
You decide what to do next. You can work through the plan yourself, ask your current IT provider to help, or talk to us about supporting you. We provide a range of managed IT services to protect organisations of all sizes.
The cyber security review is free, and the report is yours to keep. We can advise on costs for implementing any recommendations highlighted within your report.
BEC is a targeted cyber attack where criminals impersonate trusted leaders, suppliers, or colleagues as a way to trick employees into sending money or sharing sensitive data.
