Cybersecurity
Security built into the network, devices and cloud services you already use, starting with the controls that reduce the most risk.
- 01 Network security
- 02 Endpoint security
- 03 Microsoft 365 security
- 04 Reviews and hardening
Most breaches start with something basic.
A default password on a camera. A remote access port left open. A user account with no multi-factor authentication. Most security incidents in growing organisations begin with gaps like these, not with sophisticated attacks.
Our approach is practical. We review how your environment is configured today, close the gaps that matter most, and keep security settings maintained as the environment changes. Where specialist testing is needed, we coordinate it and act on the findings.
What is included
Four areas of work, each designed, delivered and documented to the same standard.

- Local admin control
03
Microsoft 365 security
Securing identity, email and files.
- Multi-factor authentication
- Conditional access
- Email protection settings
- Admin role review
04
Reviews and hardening
Finding gaps and fixing them in order of risk.
- Security reviews
- Security hardening
- Vulnerability management coordination
- Remediation tracking
How we deliver it
Every project follows the XTSURE Assurance Lifecycle. For this service, it runs in four stages.
-
Review
We examine firewall rules, network segments, remote access, endpoints and Microsoft 365 settings against a practical security baseline.
-
Prioritise
Findings are ranked by risk and effort, so the most important fixes happen first and nothing is changed without a plan.
-
Remediate
Changes applied in planned windows, tested, and recorded, with users told in advance about anything that affects them.
-
Maintain
Settings kept current, new devices brought into policy, and the review repeated at agreed intervals.
What you receive at handover
Documentation is part of the work, not an extra. Every item below is handed over in an organised pack your team can use for years.
- Security review report
- Prioritised remediation plan
- Firewall rule documentation
- Network segmentation plan
- Microsoft 365 security settings record
- Change log
Common questions
Something else you want to know? Ask us directly.
Do you provide penetration testing?
Where a formal penetration test is needed, we coordinate with specialist testing providers, prepare the environment and carry out the remediation afterwards.
Where should a small or mid-sized company start?
Multi-factor authentication on every account, a correctly configured firewall with no unnecessary open ports, separate networks for guests and devices, and endpoint protection on every laptop. These four steps remove a large share of common risk.
Will security changes disrupt our staff?
Changes are planned and communicated. Most, such as firewall and segmentation changes, are invisible to users. Changes that affect sign-in, such as MFA, are rolled out in stages with support.
